The strategy of designing around existing patents in technology innovation

PurposeThis paper aims to develop a systematic framework of strategy of designing around existing patents in enterprises' innovative activities. After reviewing the choice of strategy and principle of the design to evade the existing patents, this paper discusses how to select the target patent under enterprise's strategy, before finally taking the designing around existing patent based on patent standardisation as an successful implementation of innovative process.Design/methodology/approachThis is an exploratory research with a case study of critical technology of OTFT to illustrate the application of the proposed strategy. The choice of strategy of designing around existing patents is analyzed on the basis of judgments of patent infringement, and a framework of selecting target patent is proposed for the development of strategy of designing around existing patents as an innovation process.FindingsThis research suggests that technology innovation based on designing around existing patent should focus on choosing technology from the target patent of critical technology, choosing a policy that can balance the risk of patent infringement and costs of technology innovation and combining the policy of designing around existing patent and the application of TRIZ theory.Originality/valueThe framework proposed in this paper provides an alternative strategy of technological innovation for technology follower firms.

Fuzzy Design Scheme Selection Method Based on QFD Integrated with TRIZ

A new framework of decision-making is proposed in this paper to accommodate the application of quality function deployment (QFD) integrated with TRIZ. In the proposal framework, Ideal Final Result (IFR) oriented decision-making process is introduced for the innovation design process in order to select the best solution from alternatives which are generated by TRIZ and consistent with the laws of technical system evolution. Overall customer satisfaction oriented decision-making process is applied for the alternatives generated from both innovation design process and adaptive design process. The correlation matrix, which affects the weight of criteria, is modified according to the style of broken contradiction for the application of TRIZ. Meanwhile, triangular fuzzy numbers are utilized to deal with vagueness of human thought. Finally, an example is taken to show application of the framework.

Triz and axiomatic design: a review of case-studies and a proposed synergistic use

With increasing competition in the market, expediting the problem solving process has become crucial in the industry. As such, a number of problem solving techniques have been devised to efficiently tackle problems of varying natures. Two such techniques, Theory of Inventive Problem Solving (TRIZ) and Axiomatic Design (AD), have been widely applied in a variety of industries and services, recently. This paper reviews practical applications of TRIZ and AD in solving industrial problems related to manufacturing and designing. In addition, compatibility issues of TRIZ and AD are discussed. Based on our review, we propose a new approach of applying these two techniques concurrently to solve a problem to attain efficiency and quality in the problem solving process. The approach has been demonstrated through a real life case-study of productivity enhancement in a manufacturing industry.

How combinations of TRIZ tools are used in companies – results of a cluster analysis

Many engineers and natural scientists in companies are using tools directly or indirectly related to the theory of inventive problem solving (abbreviation derived from the Russian title: TRIZ) by Altshuller (1984, 1996). Some of the TRIZ tools are based on the application of condensed technical knowledge, others are special techniques for directed creativity. The usage of TRIZ and its tools should lead to improvement of efficiency within the innovation process as well as to more and smarter problem solutions. More than 40 reported applications of TRIZ in companies show that usually not the whole set of TRIZ tools is used. This is surprising, because in the original TRIZ literature all the tools are recommended for usage in a classified order named ARIS (Russian acronym for ‘algorithm for inventive problem solving’). A cluster analysis of the applications reveals that there are three subsets: (i) basic TRIZ, (ii) resource and ideality-based TRIZ, and (iii) substance-field based TRIZ. This leads to important consequences: TRIZ training and TRIZ implementation should be structured according to the three subsets.

Some thoughts about problem solving in a DMAIC framework

This paper explores the iterative nature of problem solving in the context of a complex system issue involving the interplay of hardware and software on a diesel engine. The case study illustrates how application of TRIZ and parameter design methodologies can greatly enhance and accelerate the problem-solving process. Slow- and high-amplitude oscillation of the entire vehicle powertrain under steady pedal position at idle is called ringing, and similar behaviour under cruise-control conditions is called hitching. TRIZ (a Russian acronym for Theory of Inventive Problem Solving) Anticipatory Failure Determination was used to discover root cause. Dr. Taguchi's parameter design was then used to find the appropriate levels for a variety of software variables to virtually eliminate the hitching condition. The use of TRIZ and robust engineering methods up-front in the design process, and the distinction between Six Sigma and design for Six Sigma are also discussed.
