Title: The Innovative Contributions of Etienne De Fontenay
Introduction
Etienne De Fontenay is a notable inventor based in Decize, France. He has made significant contributions to the field of engineering, particularly in the development of advanced joint systems. With a total of 13 patents to his name, his work reflects a commitment to innovation and practical solutions.
Latest Patents
One of his latest inventions is the hydroelastic ball joint. This invention relates to a hydroelastic joint used to assemble two pieces. The joint comprises an external reinforcement and an internal reinforcement, each having a longitudinal axis, with one disposed around the other. The joint includes a first assembly that forms a hydroelastic spring, positioned between the reinforcements. This assembly features a first elastically-deformable element designed to create at least one sealed volume containing a damping fluid. Additionally, a second elastically-deformable element is placed between the first assembly and one of the reinforcements. The design of the second element is characterized by a longitudinal dimension smaller than that of the first, limiting transversal deformation during relative tilting of the reinforcements.
Another significant patent is the suspension joint and torsion spring assembly. This invention consists of an outer tubular sub-frame, an inner tubular sub-frame, and an intermediate connecting sleeve made from elastomer material. The elastomer sleeve features at least two cell structures extending along its circumference, which significantly reduces the radial rigidity of the joint in multiple directions while maintaining torsional rigidity.
