The Ease of Grasping to Evaluate Aesthetically Pleasing PET Bottle Design

Abstract

The objective of this paper is to propose a method to evaluate an aesthetically designed product from the viewpoint of grasping. Ease of grasping, which is considered to affect the ergonomic aspect of aesthetic design, is estimated by using the moment of force in the hand when grasping the aesthetically designed product. Two grasping position are used to evaluate the ease of grasp. These grasping positions are achieved when the hand exerts a minimum moment of force. A design support system was also developed based on the design method from the previous work and current proposed evaluation method. The system is capable of providing an aesthetic design solution and to subsequently perform the ease of grasping evaluation. The effectiveness of the proposed method was confirmed in ergonomics experiment using a PET bottle shape.
