5W1H, GRA and GSM in the Evaluation and Identify on Optimal Design of Bike Lamps

This paper presents the best way to design a new product from screening the design vocabulary of the bike lamps as an example. This research aims to the optimal design of assessment, data mining based on the experience of experts, and it is hoped to contribute the technical education application on teaching the product design. For this purpose, the paper mentions about the methods of 5W1H and GRA (Grey Relational Analysis) with finding the analysis results of the design vocabulary, and get the best design vocabulary sets. Therefore, we can point out the optimal design factor of the bike lamps, and the order of the importance. The paper not only analyzes the optimal relation diagram for producing the best bike lamps, but also presents the Grey Structure Model (GSM) for an example of making the best design education.
