In order to meet all these requirements, efforts are made on piston rings because they are widely used on pistons of internal combustion engines for the purpose of sealing, heat dissipations, oil control and assisting piston motions. Many patents and products of piston rings are proposed and provided all over the world in order to improve the performances mentioned above and to reduce the manufacturing cost. This, however, also facilitates the generations of new ideas if the procedure of innovative design is well followed. In this thesis, techniques of patent search and analysis are applied for creation new concepts of piston rings, and the database for innovative design is constructed simultaneously. The patentability of new concept is also evaluated and examined for further submission of new patents.
