Research on the Design of Portable Desktop Air Purifier Based on Kansei Engineering

Following societal events involving air, such as haze and COVID-19, Chinese people’s need for air purifiers has skyrocketed. The matching degree between the appearance of air purifier and the user’s subjective preference becomes an important factor affecting the user’s purchase decision. In this paper, we utilize the portable desktop air purifier as an example of how to address customers’ perceptual needs in the air purifier’s product appearance design, based on the Kansei engineering. We established product sample space through market research and literature reading, extracted product design elements, collected perceptual image words, then used semantic difference method to measure users’ perceptual needs, and obtained key perceptual image words by factor analysis. Then partial correlation analysis is conducted on the results of the above methods to determine the translation link between design elements and perceptual image space, and a set of design methodologies for a portable desktop air purifier based on Kansei engineering was obtained. Finally, a genuine development project is used to validate the method’s practicality. The findings of this study not only aid in the design and development of air purifiers but also provide research ideas and methodologies for air purifier appearance design to fulfill the perceptual needs of consumers.

An Aesthetic Measurement Approach for Evaluating Product Appearance Design

After completing the market positioning of products, catering for the functional and emotional needs of consumers is the key to achieve the success of product design. In the present study, the psychological theory is employed to screen the subjects and quantitatively evaluate the alternative design schemes to ensure the optimal design scheme. Then, an evaluation method of product appearance design based on eye tracking and aesthetic perception measurement is obtained. With the design of campus street lamp as an example, this paper evaluates the appearance design of products using emotional measurement and eye tracking technology. IAPS is used to screen out the participants who can represent the emotions and aesthetic experience of the public. Subsequently, the index system of aesthetic evaluation is established according to aesthetic theory, and the transformation relationship between aesthetic evaluation index and physiological eye movement index is determined. Finally, the eye tracking technology is used to evaluate the aesthetic feeling of each alternative, and the best design schemes are obtained. This study aims to explore a simple, practical, and low-cost product design evaluation method. As a hotspot in the research field of product design methodology, emotional design has broad prospects for application. Moreover, this paper also proposes a new direction for the development of emotional design research, which is based on quantitative analysis with the supplement of qualitative analysis.

Design specification representation for intelligent product appearance design

Traditional intelligent product design usually focuses on functional design, aiming to generate appropriate structures that would provide required functions. Design specifications are mainly formulized into technical descriptions or values that are related to certain functional or usability requirements. In today’s global market, to in-crease user satisfaction, the appearance design of a product become vital for users to make purchasing decisions. This is particularly true of today’s consumer products such as mobile phones, digital cameras, and other electronic products. In intelligent product appearance design, design specifications are merely described as basic geometric dimensions and types of surface materials. Additionally, the aesthetic considerations and emotional needs of product appearance are seldom discussed when establishing design specifications for product appearance design. In this regard, the objective of this study is to propose a design specification representation framework for intelligent product appearance design considering both emotional and aesthetic aspects. The framework be-gins to investigate user needs by acquiring user aesthetic experience. Based on the notion of aesthetic experience, a detailed representation model of appearance design specifications is provided for satisfying user emotional and aesthetic needs. Finally, a case study of the appearance design of digital cameras is provided to demonstrate the acquisition of user needs and establishment of design specifications based on the proposed framework.

From the historical overview of design geometry, this paper briefly introduces the current popular style of product design---minimalist design. The emphasis is laid on the analysis and research of design geometry in the minimalist style product design, leading to the contemporary designer’s concern and thinking about design geometry. Thus, this paper establishes the importance of design geometry in minimalist style product appearance design.

A novel method for the evaluation of fashion product design based on data mining

It is difficult to qualitatively evaluate the design effects of product appearance. Electroencephalograph (EEG) and eye-tracking data can serve as reflection of the subconscious activities of human beings. The application of advanced neuroscience technology in industrial operation management has become a new research hot spot. This study uses EEG equipment and an eye-tracking device to record a subject’s brain activity and eye-gaze data, and then uses data mining methods to analyze the correlation between the two types of signals. The fuzzy theory is then applied to create a fuzzy comprehensive evaluation model. The neural attributes are used to quantify the factors affected by product appearance and evaluation indicators. We use women’s shirts as research subjects for a case study. The EEG Emotiv device and Tobii mobile eye-tracking glasses are used to record a subject’s brain activity and eye-gaze data in order to quantify the evaluation factors related to product appearance. This method not only scientifically evaluates the uniqueness of product appearance but also provides an objective reference for improving product appearance design.

Application Research of Chu Culture Symbols Based on the Product Semantics

In modern product design, blending traditional cultural symbols into makes more alternatives available for product appearance design, and endows the products’ internal imagery with deeper cultural and historical value, whereby the traditional culture can be spread and carried forward better. On the basis of building the product identification system model of the Chu cultural symbols, through theoretical research on the product semantics, the paper aims to explore and sum up the important associations between the product semantics and the Chu cultural symbols. We are also engaged in proposing the application methods of product semantics in the Chu cultural symbols, and making the traditional cultural symbols and the modern product design merged perfectly in the forms and connotations.

Household Appliance Product Appearance Design with Feedback of User Experience

Household appliance product design is a big trend in current industrial design circle. Reverse engineering is one of the most common CAID means in modern industrial design. In order to support reusing product appearance design knowledge, this paper proposes the model used for resolving innovative product appearance case. According to the three stages of aesthetics impression, semantic judgment and symbol contact experienced by users to cognize product, this paper divides the product into three kinds of appearance innovative types of formal aesthetics, usage mode and cultural fashion. By utilizing taxonomy principle and appearance design innovative process, this paper sets up three kinds of appearance innovative types corresponding to design knowledge frame model used for extracting and reusing appearance innovative design knowledge. Such model is applied to setting up product innovative case library, helping designer search and apply previous successful cases and realizing user-centered product development. Through the use of such database by designer, this paper shows its effectiveness.

Knowledge Model Based on Graphical Semantic Perception

Abstract Based on knowledge representation in product design, we propose a knowledge model of the product design process based on graphical semantic perception. The ontology semantic of the product is analyzed together with the product design process knowledge. Then the basic element model for knowledge representation of the product design process is built. With the concepts of the extension origin point basic element and extension vector thus defined, knowledge representation, consisting of growth, convergence and optimization is realized. On this basis, the model for case base clustering based on graphical semantics is built. Feasibility verification is performed with the case of appearance design of a machine tool. The highlight of the proposed method lies in the combination of the formalized and quantitative approach for product appearance design.

Spatial augmented reality for product appearance design evaluation

AbstractAugmented reality based on projection, called “Spatial Augmented Reality (SAR)”, is a new technology that can produce immersive contents by overlapping virtuality and real-world environment. It has been paid attention as the next generation digital contents in media art and human–computer interaction (HCI). In this paper, we present a new methodology to evaluate the product appearance design more intuitively by means of SAR technique. The proposed method first projects the high-quality rendered image considering the optical property of materials onto the mock-up of a product. We also conduct a projector-camera calibration to compensate a color distortion according to a projector, a projection surface and environment lighting. The design evaluation methodology we propose offers more flexible and intuitive evaluation environment to a designer and user (evaluator) than previous methods that are performed via a digital display. At the end of this research, we have conducted a case study for designing and evaluating appearance design of an automobile.

Theoretical Research on Inheriting Degree in Appearance Design of Brand Products

In the appearance design of a product, the designer should combine his/her creative thinking with the industrial design approaches and skills to carry out the creative design from the aspects of product’s shape, color and texture, etc. However, from the viewpoint of the brand, a company or a product should have its own unique style of appearance. How to balance the creativity of designer and the original style is often a contradiction in product design. Based on this consideration, this paper presented a concept of Inheriting Degree (ID) in product appearance design. The visual characteristics of the product appearance were analyzed first and the hierarchical system for ID in product appearance design was established. The idiographic indexes of ID were given for a product’s appearance in shapes, colors and textures, respectively. By introducing set theory, the mathematical models were established and calculation formulae for each kind of ID were proposed. The results of this paper would provide a theoretical foundation for designer to generate design concepts in brand products. It also would provide a guideline for the development of computer aided design and evaluation system for the appearance design of brand products.

Elicitation of Preference Structure in Engineering Design

Engineering design processes, which inherently involve multiple, often conflicting criteria, can be broadly classified into synthesis and analysis processes. Multiple Criteria Decision Making addresses synthesis and analysis processes through multiple objective optimisation to generate sets of efficient design solutions (i.e. on Pareto surfaces) and multiple attribute decision making to analyse and select the most preferred design solution(s). MCDM, therefore, has been widely used in all fields of engineering design; for example it has been applied to such diverse areas as naval battle ships criteria analysis/selection and product appearance design. Given a list of design alternatives with multiple conflicting criteria, preferences often determine the final selection of a particular set of design alternative(s). Preferences may also be used to drive the design/design optimisation processes. Various methods have been proposed to model preference structure, for example simple weights, multiple attribute utility theory, pairwise comparison, etc. Preference structure is often non-linear, discontinuous and complex. An Artificial Neural Network (ANN) learning-based preference elicitation method is presented in this paper. ANNs efficiently model the non-linearity, complexity and discontinuity nature of any given preference structure. A case study is presented to illustrate the learning-based approach to preference structure elicitation.

Creative design research of product appearance based on human–machine interaction and interface

According to traditional design theory, the Function–Behavior–Structure design model pays more attention to the function and structure of the product. However this model still cannot strengthen the relationship between product appearance design and human–machine design effectively. This paper adopt converse design thinking and presents a improved design thinking methodology based on Constraint:Function–Behavior–Structure for product appearance design and give a general summarization of the features, methods and technology based on human–machine interaction and interface (HMI&I). At the same time it also combines with the behavior design of product related IT fields and constructs a new outline to improve the design of product appearance supported by the technology of computer aided design (CAD). Thus a new method about design thinking for CAD, a new abstract product design model and the key problem of design thinking based on HMI&I are addressed in this paper. The creative design theory that is driven by HMI&I will help in the development of a CAD software system and in the research of product design and manufacture. Additionally the trend of design thinking based on the technology of HMI&I are also analyzed and discussed at the end of the paper.
