Problems solved by technology

However, the application of these two theories in the process of innovative design depends on the designer's experience to a certain extent, and the design results mainly rely on the designer's personal ability, and cannot objectively express the relationship between technologies.
Moreover, the above two methods cannot realize the automation of technical analysis very well, and the efficiency of product design is low

Embodiment Construction

[0024] The present invention will be further introduced below in conjunction with the accompanying drawings.

[0025] (1) Definition of basic concepts

[0026] 1) Definition of network nodes and associations

[0027] The main body of the technical network is the technical nodes and the associations between nodes. Considering the definition of technology comprehensively, the specific definitions of technology and technology network in this invention are as follows:

[0028] Technology network: G={V,E};

[0029] Technology node set: V={v 1 ,v 2 ,...,v n},

[0030] Association set between technology nodes: E={e 1 ,e 2 ,...,e m};

[0031] The value of v refers to the technical node formed by the sub-technical information extracted from the patent document. Patent documents usually describe a system that can realize a specific function, and this system is composed of multiple subsystems. Therefore, each component structure that constitutes a patent system can be defined ...

Abstract

The invention provides a network construction and evolution method based on a weighting technique in order to construct a network by existing product techniques and predict technical development trend by the network. The method comprises: first, processing data, to be specific, analyzing existing patent documents, and extracting structural information composing the patient system as sub-technique information; second, constructing a technical network, to be specific, describing each patent document, in co-occurrence relation of patient documents, as a plurality of complete graphs composed of a plurality of nodes according to the sub-technique information, connecting the complete graphs through same sub-technique nodes in the complete graphs to form a weighted undirected technical network; third, evolving the technical network, to be specific, performing evolution process of a weighted technical network based on the second step.

Description

technical field [0001] The invention belongs to the field of patent analysis and relates to a network construction and evolution method based on weighting technology. Background technique [0002] Patents and technology are important references and basis in the process of product design. Taking patents as the research object to study the development trend of technology is of great significance for enterprises to improve product innovation and design capabilities and develop new products. [0003] TRIZ and morphological analysis methods, as two classic technological evolution theories, have been widely researched and applied, and have promoted the development of technology. The TRIZ theory identifies the development trend of technology through logic and data qualitatively; the morphological analysis method decomposes the technology into several factors according to the morphological analysis technology, analyzes the possible forms of each factor, and obtains some possible sol...
