Research On E Group Technology Development From The Persepctive Of Patent

As the third-generation compressor,scroll compressor is widely used in refrigeration,heating and other fields.In recent years,scroll compressors have encountered major difficulties:in the market of small and medium-sized power air conditioners,they are faced with the extrusion of rotator compressors,which are not advanced in technology but have cost advantages.However,the high-power market is facing tremendous competitive pressure from the miniaturization of traditional screw compressors.The research object of this paper is E company,which is the world's largest manufacturer of scroll compressor.The purpose of this paper is to find out the direction of scroll compressor technology research and development and to meet the challenges of the market.Based on the market competition situation of scroll compressor in China,this paper searches and analyzes the patent of scroll compressor.The main work includes:1.Use "scroll" and "compressor" as search keywords,and use IPC to screen related patents;2.Use MATLAB software to conduct regression analysis of search results and predict future patent application trends;3.The technology life cycle of scroll compressor technology was analyzed by comprehensive application of s-curve Technologies Evolution theory in TRIZ and patent index method;4.Use the patent aggregation function of INCOPAT software to analyze the patents of E company and its competitors and draw a patent map;5.Analyze and judge the technological competition situation of E company and its competitors by using the patent portfolio theory;6.Discuss the future R&D strategy of E company based on the results of 1-5 analysis;7.Discuss how to comprehensively use IP rights to escort the technological innovation of E company.The main conclusions of this paper include:1.Scroll compressor technology is currently in the mature stage;2.Compared with competitors,E company is in the position of technology leader,while other major competitors are in the position of technology activist,potential technology competitor and technology laggards respectively;3.Future technology research and development focuses on:a)give up the low-cost competition with rotor compressor;B)strengthen the research and development of high-power products which are suitable for ultra-low temperature environment;C)in the field of high efficiency and energy saving,while increasing R&D investment in frequency conversion technology,E company should not abandon its unique digital scroll technology;D)strengthen the technical research of scroll compressor in new application fields such as heat pump and drying.
