“Lighting Battery,” gold awarded, obtained the jury’s compliments from the evaluating views of“ minimum design” by minimum materials and technological ways. In today’s society questioning what is sustainable lifestyle, the outcome of the selection can be defined as the one showed the direction of industrial design to come. Whereas some excellent works with an ecological view were found, poor design aspect was pointed out. This was the event that the essence of a design competition, not only an idea but also a proposal of a new form materialized in the works, should be again reminded.
