Universal design means the design of products and the environments in which they are used while considering usability applied to all user groups. In present circumstances, the need for universal design is increasing as advanced countries include larger percentages of aged people, and social pressures demand increasing attention to human rights, especially the needs of physically-challenged individuals. This paper proposes a methodology for obtaining optimal structural designs of compliant mechanisms that include the goals of universal design, based on the phase field method. First, a new formulation is developed that aims to reduce users' physical effort by ensuring that the location of the center of gravity the object or tool to be used is as close to the hand grip as possible. Second, an additional formulation is developed to facilitate designs that can accommodate as wide a range of users as possible, to develop structures that are stable despite different directions of input loading applied by different users. Finally, the design of a gripper that approaches a universal design was developed using the proposed formulations, and evaluated to assess the efficacy of the proposed methodology.
