Abstract
In general, even the artifacts used in diverse conditions are designed for average condition. The diversity of conditions may cause low evaluation of those artifacts under any conditions. The present study attempted to construct a design method intended for diverse conditions. As a solution, we proposed a robust design method for diverse conditions. The distinctive features of the method from conventional robust design method are application of modeling of conditions, and simulation using the model. We applied this method to the design of swing-seat function. Through the application, we obtained the ideal relationship between the back angle and the cushion angle of the seat. This result corresponded to the experimental results measured the hip-sliding force and sensory evaluation. Thus, we verified the validity of this design method and showed the possibility of application of this design method.
