Abstract There exists a need for methodologies on designing mechanical devices with flexible elements (compliant mechanisms). Many engineers currently have little direction in their designing efforts and have difficulty improving the performance of devices with flexible members. This paper presents a step towards a process and a set of rules for designing compliant mechanisms which aid engineers in selecting the best design concept among a set of alternatives. The approach is a more rational method for selecting and improving designs than the existing intuitive approach engineers now take. The general design rules aid the engineer in identifying good and bad design features and practices for devices containing flexible elements. The design rules help engineers avoid oversights and/or overlooked factors in design problems. Since many equivalent compliant mechanisms can be made from a single rigid-body solution, the rules can help engineers select between the compliant alternative designs.
