Abstract

Most authors have focused on the sizes and the shapes of the product handles, but neglected those interface materials of the handles, which could further improve the ergonomics of the product. Therefore we utilized optimisation method to determine optimal interface material properties of a product for optimal mechanical response of the system using numerical simulations of a fingertip model grasping a product’s handle. Objective function was set to find material parameters in such way that the interface material of the product stays firm during low grasping forces to provide stability of the product in hands and deforms when a critical contact pressure is reached to provide higher contact area. This increases comfort and lowers the contact pressure on the hand and thereby the risk of injury development.
