N2 - For the conception of compliant mechanisms various design aids have been proposed, including some graphical ones. In this work we propose to use the potential energy field of elastic systems to characterise their behaviour over a large motion area. The system and its characterisation can be interactively adapted to obtain a behaviour of interest. The behaviour is fine-tuned by a shape optimization procedure. This approach is elaborated in this paper for systems comprising curved planar beams. A design example is presented that can realise an unconstrained straight-line motion with a constant potential energy level, comprising four symmetrically arranged beams
