Constant-force regulation is critical in applications ranging from precision micromanipulation to overload protection. This paper introduces a novel compliant constant-force mechanism (CCFM) realized with a single flexural V-shaped beam whose variable stiffness along its length produces the constant-force characteristic. Unlike traditional CCFMs that rely on stiffness-combination architectures or curved-beam flexures, the proposed design harnesses the intrinsic stiffness gradient of the V-shaped flexure to achieve a compact form factor akin to curved-beam devices. Owing to its simplicity and small footprint, this CCFM is ideally suited for robotic end-effectors, MEMS, micro-manipulation tasks, and other advanced applications. The mechanism’s behavior has been modeled and validated through finite-element analysis (FEA).
