Knowledge acquisition from generalized experts oriented to product innovation

The essence of design innovation was the innovation of knowledge. Favorable knowledge accumulation and update mechanism were an important foundation to realize product innovation. Knowledge acquisition and innovation mode oriented to problem were offered aim at the bottleneck problem of the product concept innovation stages. Knowledge acquisition from generalized experts and innovation process which were constituted of four stages that the stages of experts think independently, the stage of knowledge acquisition from special experts, the stage of experts discuss and the stage of knowledge innovation were discussed. A method of knowledge acquisition from generalized experts based on the sample was put forward. The model of domain core ontology was built. The method of domain ontology expand based on the general ontology was founded. The emergence of the theory provided referential thoughts and methods for product innovation.
