A Study of Anticipatory Failure Determination (AFD) based on Scenario Analysis Methods

Theory of Inventive Problem Solving (TRIZ) is a methodological algorithm that helps solve complex problems by generating original ideas. The Anticipatory Failure Determination (AFD) method is one of the problem-solving methodologies within TRIZ. It is a creative way to solve problems when you cannot find the cause of a problem or observe the situation in which it occurs. This study aimed to investigate the effectiveness of the Anticipatory Failure Determination (AFD) method, which is one of the problem solving methodologies within the Theory of Inventive Problem Solving (TRIZ). TRIZ is a methodological algorithm designed to address complex problems by stimulating the generation of original ideas. It involves a shift in thinking: instead of looking for the cause of a problem (i.e., "why does it happen?"), it looks for ideas to solve the problem (i.e., "how can I make it happen?") by formulating a hypothesis and testing the hypothesis. In doing so, they explore and leverage resources that exist within or adjacent to the system to support the failure hypothesis. A resource is anything that is used to fulfill the ideal final result. In this study, scenario analysis, a methodology synonymous with foresight, is integrated into the AFD framework to enhance problem-solving capabilities. By incorporating scenario analysis, the formulation of failure hypotheses crucial to the AFD process is facilitated. Additionally, a case study demonstrating the application of AFD augmented by scenario analysis is presented, showcasing its efficacy in resolving complex problems. This integration aims to proactively mitigate future risks and prevent potential damages. Through this research, a comprehensive understanding of how scenario analysis enriches the AFD methodology is provided, empowering practitioners to pre-emptively address emerging challenges. Ultimately, the goal is to fortify problem-solving capacities and foster resilience in the face of evolving complexities.

The Approach for Identifying Opportunities in Product Innovation Design through Requirement Conflict Analysis

This study introduces a method to explore and broaden potential design avenues for a product by identifying opportunities for innovative design through requirement conflicts. The process involves clarifying user-expected demands using the Ideal Final Result approach and identifying potential conflicts by assessing product performance constraints and user expectations. Utilizing standardized representations of requirement conflicts, a knowledge retrieval technique based on expanding co-referential relationships is applied to analyze these conflicts. A judgment matrix is created to pinpoint clues for recognizing innovative design opportunities initially. Furthermore, the nine-windows method is utilized to expand and identify innovation opportunities along the time and system axis, leading to the identification of two types of innovation opportunities and their expanded outcomes. Ultimately, the method’s feasibility and practicality are validated by identifying innovative design opportunities within the context of the alpine tunnel construction system.

Application of Algorithm for Inventive Problem Solving (ARIZ) for the Heat Dissipation of Energy Storage Supply System for High-Power Locomotive

With the increasing demand for the energy density of battery system in railway vehicles, the ambient temperature of the battery system is increased. This means that the heat dissipation efficiency and battery service life are reduced, thus reducing the reliability of the battery. Contraposing the problem of the heat dissipation of energy storage batteries, the full deployment of the ARIZ algorithm has been provided for applications of problem-solving processes in this investigation. The advantage of using the ARIZ algorithm is that while the engineering system is kept unchanged or less changed, the effective heat dissipation of the energy storage battery with increasing energy density can be satisfied. During the process of the ARIZ algorithm, a mini problem is first defined. Moreover, the ideal final result and physical contradiction are defined. Following this, expanded material field resources are used, and finally, 22 innovative designs are obtained using the problem-solving tool in TRIZ theory. The final design scheme is provided by combining multiple schemes, and the heat compensator dispersion of a partially improved system in the optimized scheme has been simulated. The results show that the heat compensator dispersion of the air conditioning cooling system for battery modules has reached the design goals in this investigation, in which the maximum temperature of the module’s surface has been reduced to below 35.68 °C, and the maximum temperature difference of the module has reduced to below 5.6 °C.

Priorities for the Development of Soil Clearing Technologies

Based on the theory of inventive problem solving (TIPS), in particular, using the concept of an ideal final result, the priorities for the development of tillage technologies are established. This methodology for identifying priorities can also be used for technologies used in other sectors of the economy.

Analyzing the Implementation of a Digital Twin Manufacturing System: Using a Systems Thinking Approach

Digital twin (DT) is a technology that promises great benefits for the manufacturing industry. Nevertheless, DT implementation presents many challenges. This article looks to understand and study the problems associated with the implementation of DT models in a manufacturing domain. It applies systems thinking techniques to analyze and refine these problems. Systems thinking presents several methods and tools that help in studying a problem space and a solution space.

It maps the processes and components for DT implementation. The TRIZ method analyzes, and forecasts problems related to DT development and provides solutions based on patterns of invention. The CATWOE analysis allows identification of stakeholders and the study of the DT model from their perspectives. It provides a root definition of the DT model to refine a problem and the problem’s contradiction. The 9 windows tool helps to delimit the DT implementation problem, based on time and space. It gives eight more perspectives to solve the DT problem. Finally, the ideal final result (IFR) method provides the ideal DT model concept for manufacturing systems.

An Innovation Design Approach for Product Service Systems Based on TRIZ and Function Incentive

Good balance between product and service is the key in the innovative design of product service systems (PSS). In this study, the evolution route of the PSS based on Teoriya Resheniya Izobretatelskikh Zadatch ideal final result was provided. The function model of the PSS was constructed according to the service blueprint and function system diagrams. On this basis, an innovation design method of the PSS based on function incentive was established. The function incentive strategies included function synergy, function supplement, and function substitution. Finally, the PSS design process of agricultural machinery based on computer-aided innovation platform was analyzed to verify this method.

A new model to resolve technical problems

The Algorithm for Inventive Problem Solving (ARIZ) is a very good tool to solve complicated problems. However, it is fussy to get a specific solution under the guides of ARIZ in the Theory of Inventive Problem Solving (TRIZ). A novel approach to getting solutions for inventive problem solving in TRIZ is shown in this paper. A model named 5-R model of finding specific solutions was developed. 5-R model has four steps to obtain specific suggested solutions for technical problems. Reason-occurred-analysis is the first step in this new model. Then a clear statement of the Ideal Final Result is used to encourage breakthrough thinking and get solutions to the problem. After that, suggested resolutions can be obtained with the Contradiction Matrix, the Physical Contradiction, the Substance-Field, the Effects, Function Analysis, System Enhancement route, and Substance-Field Analysis. Finally, a reasonable specific solution for innovative problem solving can be gotten using resource analysis. 5-R model is not difficult to learn and remember. 5-R model improves the efficiency of getting solutions with TRIZ. Finally, a practical engineering problem was solved using this now model successfully.

DO ALL CREATIVE STIMULI WORK THE SAME? INSIGHTS FROM A WORKSHOP WITH PROFESSIONALS

AbstractThe paper presents a comparative study that explores the effectiveness of creative stimuli to foster the generation of creative ideas in non-trained professionals during a co-creative design session. Solution-related stimuli (e.g. patents or biological strategies) are confronted with problem-based stimuli (e.g. TRIZ contradictions or Ideal Final Result), which are less studied in the literature. The 40 participants to the experimental activity benefited from both kind of stimuli, but the solution-related ones allowed a more comprehensive exploration of the design space.

Using TRIZ for Maximizing Information Presentation in GUI

The modern software tools provide numerous graphic elements in their GUI, which demand more and more screen space. As size of a display screen cannot be extended beyond a limit, it is typically seen as a constraint in a graphical user interface. Looking from a TRIZ perspective, computer screen should display all information that user needs (Ideal Final Result). There are various methods of addressing problem of screen space, some of which are, using icons for windows, the desktop metaphor, the large virtual workspace metaphor, multiple virtual workspaces, overlapping windows and increasing dimensions etc.There are many inventions on how to maximize presentation of information on a graphical user interface. This article analyzes nine inventions from US Patent database from a TRIZ perspective illustrating how they solve contradictions in order to achieve desired result.

Inventions on User Configurable GUI A TRIZ Based Analysis

The graphic user interface is a revolutionary development over the prior art technique of the command line interface. Using GUI the user can do even complex operations through simple means like clicking buttons or dragging various graphic elements. Ideally the GUI should contain all those buttons (or menu items or other GUI elements) and only those buttons (or menu items or other GUI elements) that the user needs. Besides the GUI elements should not obscure the display of data, should take no time for searching and should create no confusion in any level of user. Generally the GUI elements are all pre-coded and built into the system by the developer. Even the experienced developer cannot realistically anticipate what options will be required by the users at a future point of time. As it is ultimately the user who knows his requirement, it is better that the user himself configures the GUI according to his requirement. The article discusses the problems involved in implementing user-configurability and illustrates twelve inventions from US Patent database on the same issue. Each invention is analyzed from a TRIZ perspective to illustrate the contradictions, Ideal Final Result and Inventive Principles.

Using TRIZ to Design Error-Free GUI

A graphical user interface has a lot of advantages over its predecessors. Its beauty, simplicity, adaptability, user-friendliness, visual clarity, speed and ease of operation have made it popular and suitable to a broad range of users. But a GUI also has certain limitations. Like any other type of user interface, a GUI can also be operated wrongly which may yield undesirable results. A good GUI should be intelligent to determine user's intention and disallow him doing wrong operations. A less error-prone GUI is certainly more effective and efficient. Ideally the GUI should prevent users from doing any mistake while operating the GUI. A better GUI would intelligently detect and automatically correct all wrong operations done by the user (Ideal Final Result).The article analyzes the features of an ideal GUI, finds out the contradictions in achieving the ideal features and illustrates alternative methods of solving the contradictions. Seven patents are analyzed from US patent database illustrating how each of them tries to reduce operational errors in a GUI.

Arranging Display of GUI Elements - A TRIZ Based Analysis

One of the biggest drawbacks of the graphical user interface is that it consumes the active display area associated with the device. Whether the display screen is a part of a television, computer, or any other consumer device, the graphical user interface appears on the active area of the display screen. As a result the GUI masks a part of the display screen and the amount of information that can be viewed on the screen is reduced. Ideally the GUI should offer all its features without blocking any part of the display screen. The features should be readily available and the user should not face any difficulty in searching them. Operating the GUI should require minimum amount of pointer movements.This article analyses nine inventions from the US patent database from a TRIZ perspective. The analysis tries to draw the Ideal Final Result and illustrates how each of these inventions solves the contradictions in order to achieve specific aspects of the Ideal Final Result.

Using TRIZ for Improving Navigation in Graphical User Interface

A typical user interface consists of several buttons, menus, windows, trees and other type of controls. The increased number of GUI elements and complexities of the GUI controls necessitate the user to acquire certain level of skill and efficiency in order to operate the GUI. There are many situations which further make the navigation difficult. Ideally the user should face no difficulties in navigating through the user interface. Any operation in the graphical user interface should require minimum pointer operations from the user (Ideal Final Result).This objective of a graphical user interface has led to several inventions trying to make the navigation simple and efficient. The article analyzes some inventions from US Patent database and illustrates how each of them has tried to solve different problems of navigation in a graphical user interface.

Identification and Analysis of Cold Metal Defect in Ferrous Casting using TRIZ Integrated Six Sigma Approach

Casting is a process to produce products of complex shape and size which is very difficult to produce by other processes. The various areas in casting process are pattern making, molding, core making, melting, pouring, etc.., It is very difficult to produce defect free casting. There are many defects that affect the quality of casting. This paper represents the procedure to analyze and minimize the cold metal casting defect in Pump Mounting Flange of gray cast iron. The gating systems are not always responsible for the defect occurrence. Here an attempt is made to identify the reason for the cold metal defect using TRIZ integrated Six Sigma approach. The six-sigma (DMAIC) methodology is adopted to carry out the work. Using TRIZ (Theory of Inventive Problem Solving), a tool for inventive problem solving the worsening features and improving features are identified from the TRIZ contradiction matrix and quality tools an ideal final result is obtained. The quality tools such as histogram, cause-and-effect diagram are used in various phases of six-sigma methodology.

트리즈 학습용 소프트웨어 Do-TRIZ 개발

TRIZ is a theory of inventive problem solving. Recently the importance of creative capabilities is being emphasized and many successful cases using TRIZ are being introduced, therefore interest in TRIZ has been increasing. But TRIZ is not easy to learn alone compared to other creative thinking tools. Although it is effective to learn TRIZ through various cases, it is not easy for beginners to experience those many cases. Therefore, we developed a software called Do-TRIZ for TRIZ learning. Do-TRIZ provides descriptions and various examples of key concepts to make it easier for beginners to learn TRIZ. Also, the learners can add new cases continuously on Do-TRIZ. Especially, process-based problem solving modules have been implemented on Do-TRIZ, in order to make it possible to solve problems based on technical contradiction, physical contradiction, and IFR(Ideal Final Result). The learners can use the modules to solve their problems and to share the results. Also, we implemented Do-TRIZ Memo app that works with Do-TRIZ.

Research on IFR of Technological Evolution Bifurcations

Idealization is a powerful tool in TRIZ, and it plays an important role in innovation processes. In the fierce market competition, in order to adopt new technology and make their product approach to ideal product, enterprises spare no effort to improve the degree of product's idealization. At the bifurcation points of product technology evolution, the ideal result that customers need changes, but because of the existence of conventional thinking and market competition, engineers always engage in designing according to the original target ideal result, finally the technology innovation opportunities are lost, so it is of great significance to study the Ideal Final Result (IFR) at the bifurcation points. According to different innovation processes of S-curves, the IFR for product's technology evolution bifurcations are divided into four classifications, Incremental Innovation Ideal Final Result(IFR_II), Radical Innovation Ideal Final Result(IFR_RI), Low-end Disruptive Innovation Ideal Final Result(IFR_LDI) and New-market Disruptive Innovation Ideal Final Result(IFR_NDI). Product's technology system consists of several technology sub-systems, correspondingly, ideal product is made up of several idealized technology sub-systems. It is the objective of product design that realizing the idealization of technology subsystem through innovation design, however, because the presence of conflicts and design constraints among technology sub-systems, the design aim for realizing ideal final results of each sub-system is almost impossible. Therefore, in designing processes, engineers always give priority to several mainstream technology sub-systems and realize their idealization first. This paper decomposes IFR into several ideal results of sub-systems based on a technical system decomposition method, researches a process of technology evolution and a changing process of sub-systems’ ideal results, determines evolution bifurcations’ direction of technology systems through the combination of the sub-systems’ ideal results and then realizes the technology forecasting at the evolution bifurcation points.

Brewing Free Beer: Using Ideality to develop a ‘Free-to-use’ TRIZ Effects Database

This paper describes how the TRIZ concept of Ideality was used to inform the development and deployment of a ‘free-to-use’ TRIZ database of scientific and physical effects. The TRIZ ‘Time and Scale’ framework (also known as Nine Boxes, Nine Windows or System Operator) is used to structure the narrative based on three phases: Pre-Development, Development and Post-Development.In the Pre-Development phase it was recognized that most comprehensive effects databases tend to be commercial products providing excellent content but at a price presenting a potential barrier to their use, especially by those new to TRIZ. The few ‘free-to-use’ effects databases that were available tended to be less comprehensive than the best of their commercial rivals.This led to an Ideal Outcome (or Ideal Final Result) for the effects database: “delivery of complete and perfect results to any user without restriction or cost”. This highlighted a contradiction between the performance of the system (primarily represented by the quality and quantity of the results it produces) and the cost of delivery (primarily represented by the cost of developing the database infrastructure and collecting and collating the database content).As the project moved into the Development Phase this contradiction was tackled using a three-pronged Ideality-based strategy of: focus on delivering only the essential Benefits, reduction of Harms that detract from the essential Benefits and finally reduction of Costs by using existing and/or low-cost resources.Focusing on essential Benefits resulted in the selection of a simple database design that minimised the data required to populate the database. The principle Harm (where Harm is an output that is not useful) considered was that of an inaccuracy in the results delivered to the User. A taxonomy of database inaccuracies was compiled and each identified inaccuracy type considered in terms of its influence on the Ideality of the database system. This revealed, somewhat surprisingly, that inaccuracies were not only inevitable but were also not critical to the overall usefulness of the system. The principle resources used for cost reduction were: open-source database development tools, available internet resources and people.The Post-Development Phase was triggered in October 2011 with the deployment of the database on the Oxford Creativity website (www.triz.co.uk). The principle activity since that time has been a series of content updates. In addition consideration has been given (somewhat belatedly) to other aspects of the Post-Development column of the Nine Box model. The User's perception of Ideality has shifted from “Can I have more results” to “There are a lot of suggestions here – can they be filtered in some way?” This is a useful reminder that (in common with most systems) the database falls short of delivering the Ideal Outcome of complete and perfect results. Some candidate routes towards the realization of this Ideal are suggested.

Supporting ECO-innovation in SMEs by TRIZ Eco-guidelines

An Eco-Design methodology based on two abridged Life Cycle Assessment tools (eVerdEE [1] developed by ENEA [2] and the French Standard NF 01-005) plus TRIZ [3] Eco-guidelines is presented. This method is one of the outputs of the European project REMake [4] (started September 2009 ended December 2012), which had the goal of developing and testing new approaches for eco-innovation, recycling and material consumption for manufacturing small and medium sized enterprises (SMEs). The number of SMEs involved in the project has been around 250, in six countries.The proposed method consists of a preliminary scanning of a given product or process in order to disclose all the material involved and the energy flows, and to assess their environmental impact by means of a simplified Life Cycle Assessment (LCA) approach and the related indexes. The “hot spots” of the product or process are then identified by adding a brand new index called “IFR (Ideal Final Result) index”, conceived from the TRIZ “Ideal System” concept [5], to classical LCA criteria.Once the hot points are identified, a set of over 300 TRIZ based eco-design guidelines [6,7] are selectively introduced to develop design variants to the given system with the aim of providing a lower global environmental impact. An in-depth explanation about ECO guideline implementation is given, together with a case study concerning a manufacturer of machine tools.

TRIZ Methodology Adapted to Hybrid Powertrains Performances Evaluation

On-going oil stock depletion and growing environmental concerns lead automakers to develop more efficient powertrains. Today the most promising way forward consists in research on hybrid systems. The present study uses TRIZ methodology to help identify the best hybridization architecture and powertrain design, in order to reduce CO2 emissions. This optimization problem is constrained with cost, mass and complexity targets. It is applied to B segment hybrid electric vehicle (HEV) with no connection to the grid to recharge the battery.A specific procedure based on TRIZ principles has been established and rolled out after a first mathematical analysis of different current hybridization architectures (series, parallel and combined). The adapted TRIZ methodology is mainly built on the principles of Ideal Final Result and on networks of contradictions. It is used to compare the performances of the different architectures, identify the main technological barriers for more CO2 savings, and propose a roadmap to overcome them.

TRIZ as a Tool to Develop a TRIZ Educational Method by Learning it

Since last year, in France, an official education program includes more than 50hours of innovation methodology and training mainly based on TRIZ methods! But the problem is that teachers of the classes (sciences and technology for engineers and sustainable development) do not have any training on TRIZ, or will only receive it in the next years... So the contradiction is that teachers have to be taught about TRIZ methods to be able to teach it, but teachers could not be taught on TRIZ methods as there are no time resources to do it.With the aid of an external TRIZ expert, it has been proposed to use as a main resource a team of 6 teachers and the time of course preparation to both teach teachers and develop a new, innovative teaching method. This experiment started this year for 2 classes to inventively teach TRIZ to teachers “in real-time” while students learn it by practicing the innovation methodology and creativity tools through a project.The paper describes the 3-level approach to “develop a new educational method”, to “teach the teachers” and to enable students to learn through a “creativity challenge for innovation”. The identified key problems related to this new educational method and the results of this new approach will be presented. As results, one can notice a new way of evaluating where everybody wins (education system, teachers, students), based on contradictory parameters in a “2D radar” highlighting students’ inventive abilities. From initial state to Ideal Final result, the paper explores the key success factors, the next steps and the set of problems linked to the implied actors: teachers and students, and also the educational system. The originality of the approach is that typical solutions used in learning with industries have been applied in the educational system, whereas it is traditionally the opposite…
