| dc.description.abstract | In this thesis, which based on the related patent law, the judgment examples of the patent invasion, and the professional technique, we will use the system analysis to propose an innovative methodology for design around under the constraints of the mechanism type patent.
First, the type of the machine members and the joint will be defined according to the patent law. By using the separating rule of the essential element and the concept of the graph theory, we will transfer the extent of the patent to the patent code. According to the concept by transferring the patent essential element to the mechanism element, the extent of the applied patent can be represented by the mechanism structural diagram. According to the generalized rule, the structural diagram of the mechanism patent can be transferred to the generalized kinematical chain. By processing the redundant essential element of the patent, the multiple cycle methods for searching the feasible solution could be formed. For every cycle method in searching the feasible solution, which was based on the number of the link and joint of the generalized kinematical chain, the generalized kinematical graph can be divergently found in the catalogue index of the link kinematical data base. Based on the feasible mechanism of the elementary regulation as the judgment index, the obtaining which was obtained by the convergent process could be used as the specialized and generalized kinematical chain. Based on the feasible mechanism of the elementary regulation which was specialized, the specialized chain could be divergently totally found, and the Polya’s theorem was used as an evaluation method. In terms of the constrained conditions for the feasible mechanism of the elementary regulation, the infeasible specialized chain could be canceled and the all feasible specialized chain could be obtained by the convergent process. Using the opposite way of the generalized rule, the feasible specialized chain could be transferred to the structural diagram of the mechanism. Using the separating rule of the essential element and the concept of the graph theory, the every feasible mechanism could be totally represented by the production junction matrix. After comparing the production junction matrix with the patent code, the quality and quantity of the patent infringement could be easily evaluated.
Finally, two patents were used as example; one is the abrupt stopping apparatus using the cutting samples as reference, and the other one is the protective apparatus preventing Lathe tool from breaking. The two examples further explained and proved the feasibility and effect about the method proposed by us in this thesis. | en_US |
