Research On Multidimensional Resource Extraction And Application Mechanism

Resource analysis,as an important problem analysis tool,is widely used in technology innovation theory.To a certain extent,technological innovation is the process of resources application and reconfiguring.With the existing framework of resource analysis methods,the professional knowledge of designer is a vital influencing factor on the results of resource analysis.At present,most resource analysis methods focus on seeking resources in the problem area,system resources and the resources of supersystem,and these methods lack of mining and application of knowledge resources in patent.The researches on multi-dimensional resources analysis and extraction principle including patent knowledge resources based on traditional resource analysis methods are scarce.Based on the comprehension of existing resource analysis methods,this thesis proposes a multi-dimensional resource analysis and extraction method for system invention resources and patent knowledge resources.And this thesis also formulates a resource capture and application strategy in the process of innovative design based on the performance requirements of products at each stage in technology life cycle and corporate development strategies to assist the designer with completing the product innovative design and improving the independent innovation efficiency of the enterprise.The main work of this thesis is as follows:1.The analysis process of multi-dimensional resources.On the one hand,the existing system function structure and function model are constructed.And the available resource mining in the system is completed based on the combination of two function analysis methods.Compared with using only one of the above function analysis methods for resource analysis,this method improves comprehensiveness and effectiveness.On the other hand,by expanding and mutating the target function of the problem,the patent text that can capture knowledge resources is determined.With the Apriori algorithm and regular expression extraction in data mining technology,the innovative knowledge resources contained in patents for mechanical products are identified.The available resources captured by the above two dimensions are used as structured design information to assist subsequent product improvements and innovative designs.2.The extraction and application strategies of multi-dimensional resource.Firstly,with the functional analysis,idealized level calculation formulas and analytic hierarchy process,the resource application priority of each technical subsystem of the target product is determined to resolve conflicts in resource requirements of multiple systems under resource constraints.Secondly,the different resource capture and application strategies for products at each stage of the technology life cycle are formulated based on products’ performance requirements and the differences in corporate development strategies.The multi-dimension resource analysis is combined with TRIZ problem solving tools to complete product innovation design.It reflects the non-uniformity of resource consumption density and the difference of resource utilization methods in the innovative design of technical systems.3.Taking the solar panel cooling system as an example,the above-mentioned theory was applied to analyze and mine multi-dimensional available resources of the solar panel cooling system,and the final design scheme of the solar panel cooling system was determined,which verified the effectiveness and feasibility of the research results.
