Abstract:

The scientific principle of technical innovation often comes from other domains. The larger the span between domains is, the higher level of innovation we will get. By combining ontology and semantic technology, which aimed to realize reuse and sharing of information and knowledge, with theory of inventive problem solving TRIZ, method of solving technical conflict based on ontology was proposed and the flow chart of solving technical conflict based on ontology was given. By making use of ontology construction software protégé and ontology description language OWL, on the basis of technical conflict solution theory, which came from TRIZ, the technical innovation ontology was constructed, which will pave the way for ontology based technical innovation in semantic web in the future. The validity of this method was proved by a case study, which described technical innovation of critical part of dynamic compaction machinery self-release mechanism. 
