Universal Design is a fundamentals of good design. A product with Universal Design approach should provide wide range of solution for people with different purposes including those with diverse disabilities. However, designers often based on a subjective understanding of Universal Design Principles (UDP) to formulate design solutions. This result in the inaccurate conversion of design needs. A systematic approach is needed in order to develop a concept to meet the customer need. Previous studies shown potential integration of the Theory of Inventive Problem Solving (TRIZ) proposed to create a systematic approach for problem-solving requires creativity abilities. The purpose of this study is to explore the construction of the integration model of UDP and TRIZ 40 inventive principles. To construct the integration model of UDP and TRIZ 40 inventive principles, this study will use focus group discussion of certified TRIZ experts in the exploration of establishing an integration model of UDP and TRIZ 40 inventive principles. The further discussion onto the elements required to create the integration model by the TRIZ experts will be taken into consideration to construct a final model UDP-TRIZ model. Finally, the results are expected to lead towards a final integration model of the UDP and TRIZ integration model.

Visually impaired person has a difficulty in identifying the product function and usability. There is a need to integrate haptic exploratory procedure (HEP) of visually impaired person with universal design principle (UDP) in order to construct structural design approach. The purpose of this study is to construct theoretical framework for universal design approach considering haptic exploratory procedure (HEP). This study uses literature on visually impaired person haptic exploratory procedure (HEP) in order to identify the object properties translated by visually impaired person. Then, it uses literature of universal design to identify universal design approach in concept design process. Then, approach of TRIZ is explored in proposing systematic approach. Finally, the results are expected to lead towards model of theoretical framework of universal design approach using TRIZ and HEP. It can provide a helpful foundation for structuring the experiences to develop further the knowledge and understanding of objects for universal design. This theoretical framework contributes in designing structural UDP approach with consideration of visually impaired person HEP. It improves product usability in designing a universal design for visually impaired person.

China is steeped in a long history and splendid culture, where minority cultures add brilliance to traditional Chinese culture like bright pearls. For example, the culture of the Yi people showcases the richness of Chinese minority cultures, and at the same time, it is of special significance to traditional culture. From the perspective of the three-color culture (referring to black, red, and yellow) peculiar to the Yi people, this paper will analyze the features of the three-color culture and the colors, and study the unique aesthetic ideas of the three-color culture in the long history to demonstrate the Yi people’s color-favored customs and connotations of traditional culture.This paper consists of two important parts. First, it describes the traditional color culture of the Yi people and the features of these colors. The Yi people have a long history of the reverence for colors and a deep cultural heritage, which is a product of cultural accumulation. The Yi people have their unique understanding of colors, which comes from their life and nature. The reverence for and the worship of black, red, and yellow also has a long history and reasons. The features of these three colors unique to the Yi people reflect the culture of the Yi people and their emotions, embodying the unique color culture of the Yi people. Second, it studies the aesthetic ideas of the color culture of the Yi people, which is the focus of this paper. It analyzes and studies the aesthetic principles, styles, and ideas of the color culture of the Yi people deeply through centering on their costumes, lacquerware, and unique dance poems. With unique styles, the costumes of the Yi people are varied in colors, mainly using black, red, and yellow. Such use of colors creates a stark contrast, highlighting the characteristics of the Yi ethnic group’s costumes and its ethnic features. The lacquerware of the Yi people is an expression of their unique aesthetic understanding of the use of three colors and the area of colors used. The color rhythms demonstrated with the help of a symmetric and harmonious application of colors is an important feature of the Yi ethnic group’s lacquerware. The dance poem is a unique way to display the three-color culture of the Yi ethnic group. The black, red, and yellow are interpreted through three chapters by using the simplest colors to match the dance, creating a stark contrast that not only demonstrates the unique color culture of the Yi people, but also highlights the characteristics of the Yi people and their aesthetic ideas. Therefore, the research on the Yi ethnic group’s color culture starts from three colors including black, red, and yellow, and explores the history of the culture as well as the characteristics of the Yi people, aiming to help people deepen their understanding of the color culture and the color-favored psychology of the Yi nationality, and the unique aesthetic ideas of this group. And this can further help us identify the special value of the Yi ethnic group’s color culture and promote the spreading of the color culture of ethnic minorities.In the context of the times, the colors used by ethnic minorities all demonstrate their own ethnic characteristics, and it relates to people’s life and emotions, and nature. Therefore, it can be said that the choice of colors not only reflects one’s aesthetic appreciation but also embodies the desire for life and a recognized culture.
