Abstract:Environmental benefits related to home appliance life cycles depend on how these products are used. Designing home appliances that promote sustainable behavior is an effective way to reduce environmental impacts. This study aimed to increase relevant opportunities for promoting sustainable behavior practices on the new poor through home appliances, which is rarely discussed in the fields of design for sustainable behavior (DfSB) and product design. In particular, relevant assessment tools or indicators are lacking in DfSB, and people's use of home appliances is generally unsustainable. Therefore, repertory grid technology was used to understand the perceptions of the new poor, develop an assessment tool, and construct design strategies for home appliances that promote sustainable behavior. Data were collected from the new poor and from designers. Through cluster and principal component analyses, three strategy types were proposed that corresponded to different product features, suggestions, and guidance. In addition, the effectiveness and potential of an assessment tool were demonstrated using the Wilcoxon rank test. The findings could be used by designers, retailers, and green marketers to propose effective product design programs that promote sustainable behavior of the new poor during product use.

This study expands the definition of the poor group and attempts to delve into and make known the phenomenon of poverty in Taiwan and aims to explore the goals and possibilities of the BOP consumer market. Through a questionnaire survey and expert interviews, this research adopts the concept of sustainability to discuss the lifestyle and consumption characteristics of the BOP group and establishes a design strategic norm of the sustainable products. The findings show that the BOP group in Taiwan is new poverty or working poor and high quality and common prices are the main requirements; these should be introduced into the development model of sustainable design.

In the category of design education, the effective transmission and understanding of knowledge are the key elements for the success of design practice. Although the design teaching method is two-way communication between teachers and students, cognitive gaps in teaching contents often occur, especially in a product design course. In order to achieve consistency in cognition and teaching, this research took green household appliances as the example, and applied the Zaltman Metaphor Elicitation Technique (ZMET) and the Means-End Chain(MEC) Theory, in order to explore the experience and opinions of students in a design department. According to the analysis results, 27 common constructs were obtained, including 9 attributes, 10 consequences, and 8 values, and 3 major expectation dimensions were summarized, namely "environmental sustainability", "use feeling", and "life & health". Moreover, according to the consensus, the ACV connection model was confirmed. The results of this research can be provided to teachers as course guidance to develop green products and expand student's opportunities to realize the specific goal of product design.
