Abstract
The impacts on the environment of many commercial products have not been fully considered in past years. For the sustainable development of Earth’s resources, future product design should move towards not only innovation, but also fundamentally in the green direction. Currently, the BioTRIZ method may provide a satisfactory solution for a single contradiction of green product design. However, if there are multiple contradictions existing due to multiple operational fields, difficulty in implementing design aspects may be posed. For this reason, this paper develops a BioTRIZ multi-contradiction resolution method targeting a green product design, which can find the crucial contradictions and thus achieve the necessary invention principles (IP). By summarizing the green factors and further dividing operational fields, the deduced matrix table becomes highly effective in the design. Accordingly, designers can be assisted to quickly find the operational fields under multiple contradictions. The effectiveness of the proposed method is verified using a product example of a window-cleaning robot design.
Highlights
The development of technology plays a crucial role in economic growth
On the other hand, based on the inspiration from biological nature, product design with biomimetics is involved in the green design process [5]
BioTRIZ originated from biological functions, and it is based on subdivision of the operational fields using biology-related engineering parameters (EP)
Summary
The development of technology plays a crucial role in economic growth. it was usually focused on novelty and economic practicability in past decades, somehow ignoring the impact on the environment [1]. Development of methods for what drives sustainability, innovation, and value in green design continues to move forward [3]. A green design on aspects of sustainability is involved in strategies for sustainable innovation with bionics. This concept inspires the proposed BioTRIZ multi-contradiction resolution method. Chen and Hung [11] proposed an eco-innovation design method combining bionics and TRIZ, and established the connection between biological cases of TRIZ and invention principles (IP) through keywords. Conclusions are made, and prospective work is suggested for future study
