基于预期失效分析的伞型专利组合规避设计

寻求专利保护是企业发展的基本专利战略。一类由互补性专利组成的伞型专利组合是通过挖掘同一产品系统存在或潜在的更多技术问题而形成的具有互补技术特征的系列专利方案,通过更大的专利权利保护范围实现对同一产品系统的全方位保护。预期失效分析(Antucupatory failure determination,AFD)作为在发明问题解决算法(Algorithm for inventive-problem solving,ARIZ)中理想解和冲突的基础上发展起来的失效预测分析工具,成为发现失效问题的一种相对成熟的方法,能挖掘现有的产品系统各方面的问题以及预测尚未发现的问题。提出通过伞型专利组合分析、失效分析、TRIZ工具解决问题、专利性评价四个步骤组成的基于AFD的伞型专利组合规避设计,首先通过对规避对象产品系统进行专利组合分析,标定对象产品系统的专利权利范围,为创新设计设定了界限并提供了研究线索;其次,运用AFD进行失效分析和失效预测,确定系统已存及可能的失效点;再次,通过应用TRIZ方法产生出创造性的解决方案;最后,利用专利实质授权条件评价筛选方案并进行专利申请。应用该流程对一种擦窗机器人进行创新案例分析,形成具有自主知识产权的创新设计方案。

Patent Design Around Method Based on AFD for Umbrella-type Patent Strategy

Seeking patent portfolio protection is the basic patent strategy of enterprise development. A kind of parachute patent portfolio strategy combined by complementary patent is the series patent scheme with different technical effect, which is formed by mining the same product or technology scheme’s existing or potential problems, therefore, the comprehensive protection of same productions and system is realized by a broader patent rights range. Based on the theory of ideal solution and conflictive solution of algorithm for inventive-problem solving(ARIZ), Antucupatory failure determination(AFD) has developed into a failure prediction analysis tool, which can dig all aspects of existing technical system problems, forecast problems that are never found, and have certain conjunction with the construction of parachute patent portfolio. Therefore, based on AFD, a kind of parachute patent combinational design which steps include parachute patent portfolio analysis is puts forward, AFD, TRIZ and patent evaluation. Firstly, calibrate the patent rights scope of existing technology through the patent analysis, set constraints of innovative design and provide problem clues; Secondly, conduct failure analysis and failure prediction by AFD, determine possible failure points of the system and dig several problems; Thirdly, generate creative solutions of problems through applying TRIZ. Finally, use patent essence condition assessment screening program to apply for the patent. In this article, the program is applied to do the innovative case analysis of a window cleaner robot, and the innovative design solutions with independent intellectual property rights are formed.
