Abstract: This article explores the synthesis of a planar overconstrained mechanism potentially for a folding hinge application. Inspired by a folding hinge patent from a phone company, the author analyzes the linkage and discovers ...

Abstract: According to Camus’ theorem, for a single degree-of-freedom (DOF) three-body system with the three instant centers staying coincident, a point embedded on a body traces a pair of conjugated curves on the other two bodies. ...

Abstract: This paper proposes a method to deal with the orientation uncertainty problem affected by joint clearances. To solve this problem, it is necessary to establish the theory of mobility of the floating link of multi-loop ...

Abstract: This paper proposes a kinematic model to evaluate the orientation uncertainty range of spherical linkages caused by the joint clearances. Based on the concepts of imaginary clearance link, spherical N-bar rotatability laws, ...
