# Research on Design Method of Product Functional Hybridization for Integrated Innovation
## 5 Discussion and Conclusions  
Hybridization design is a new pattern of integrated innovation. This paper presents the concept of product functional hybridization and establishes a process model for product functional hybridization design. A method of obtaining goal products was proposed according to scenario analysis and the divergence tree. Scenario-related products were acquired from three perspectives of action objects, people, and objects, and then the goal product could be obtained. A product gene model oriented to functional hybridization was established according to the idea of biological genes. A method of establishing product concept structure based on product gene recombination was proposed in combination with the TRIZ theory to achieve the fusion of product function systems. As far as theoretical implications are involved, this paper expands the existing theory of product hybridization design from the viewpoint of function, systematically and effectively achieves product functional hybridization, and further reflects the superiority of integrated innovation. Firstly, existing methods of product hybridization design focus on technological recombination, so this paper proposed the concept of product functional hybridization and classified it into intraspecific function hybridization and distant function hybridization to meet the multi-functional needs of users. Then, to address the problem of existing functional integration methods acquiring goal products too widely, this paper proposed three paths of goal product prediction for functional hybridization by combining scenario analysis and the divergence tree. According to the prediction paths, the extension models of the prototype product's relevant elements were extended to obtain the goal product, which reduced the acquisition scope and increased the accuracy of acquisition. Finally, in response to the problem that there is less research on fusing existing product function systems in the existing functional integration methods, based on the idea of biological gene recombination, this paper creatively fused design information through the operation of product gene recombination, which improved the overall performance of the product. The core idea of integrated innovation is to optimize, match, and integrate existing product resources. With the intensification of social competition, how to make full use of existing product resources for integrated innovation has become a key concern for enterprises. By applying the design method of product functional hybridization proposed in this study, enterprises can use their own products and other existing product resources to form different kinds of multifunctional products to adapt to the development and changes in the market and improve market competitiveness. This study can help enterprises to fuse their own products with other existing product resources to improve the overall performance of their products while reducing manufacturing costs and achieving maximum benefits. Despite the advantages of the new design approach, there are some limitations in this study. * Acquiring goal products is the key to successfully implementing product functional hybridization. The acquisition method proposed in this paper can accurately acquire the goal products of functional hybridization. However, the extended elements need to be analyzed one by one based on the divergence tree in the acquisition process, which makes the acquisition less efficient. * A new product concept structure can be effectively formed in the product functional hybridization design process with product genes. However, the establishment and reorganization of product genes are completed with the experience of designers. * During the case study, a concept structure of the new tree-planting machine was established according to the process model for product functional hybridization design. Although the overall performance of this new concept structure was improved compared with the prototype product, the specific extent of improvement is to be considered.
