【摘要】：面对日益激烈的市场竞争环境,自主创新是企业生存发展之道,企业自主创新的根本是产品创新。TRIZ是在世界范围内得到广泛应用的发明创新理论,以TRIZ为基础的计算机辅助创新技术可以将多学科领域知识有机地综合起来,帮助设计者打破思维定势,拓宽有限的知识领域,更有效地实现产品创新设计。本文的主要研究内容如下：本文首先分析了基于TRIZ的CAI技术国内外研究现状,学习和了解了TRIZ及相关产品设计理论。其次,以TRIZ理论中的分析工具和知识工具为基础,VisualC++6.0为系统开发平台,结合Access数据库和XML技术,构建和实现了基于TRIZ计算机辅助产品创新设计系统。整个系统包括八个模块,分别是系统登录、问题定义与分析、冲突问题求解、物场分析求解、功能科学效应求解、知识库管理、专利检索与分析和生成报告。在软件系统构成方面,一定程度上全面支持产品创新设计中问题定义、分析、求解到报告生成的整个过程,是一个完整的计算机辅助产品创新设计系统。在软件功能模块设计方面,着重探讨了标准解和科学效应知识在产品创新设计中的应用过程,完善了应用标准解的算法流程,使得标准解的应用过程更为系统化和具有可操作性,并利用XML技术实现了科学效应知识库中基于功能的语义扩展和同义词辨析的检索功能,提高了知识的查全率和查准率。在知识库系统设计方面,以TRIZ知识工具和专利文献知识为创新知识来源,包括创新原理知识库、标准解知识库、功能科学效应知识库和工程设计案例库四个部分构成创新设计知识库系统,软件中知识以文字,动画、图片等多媒体方式呈现,为设计者提供多学科领域的创新知识,易于设计者掌握和运用。最后,本文以洗衣机节水创新设计和风扇降噪的创新设计、打印机专利检索及其技术成熟度预测、知识库管理为例全面介绍和测试了软件系统各模块的运行和操作过程,并给出了相应的创新方案,验证了系统的正确性和有效性。
[Abstract]:In the face of increasingly fierce market competition, independent innovation is the way for enterprises to survive and develop. The fundamental of independent innovation of enterprises is product innovation. Triz is a theory of invention and innovation that has been widely used in the world. The computer aided innovation technology based on TRIZ can integrate multi-disciplinary knowledge organically, help designers break the set of thinking, widen the limited knowledge field, and realize product innovation design more effectively. The main contents of this paper are as follows: firstly, this paper analyzes the current research situation of CAI technology based on TRIZ, and studies and understands TRIZ and related product design theory. Secondly, based on the analysis tools and knowledge tools in TRIZ theory, Visual C 6.0 is used as the system development platform, combined with Access database and XML technology, a computer aided product innovation design system based on TRIZ is constructed and implemented. The whole system consists of eight modules: system login, problem definition and analysis, conflict problem solving, matter field analysis, functional science effect solving, knowledge base management, patent retrieval and analysis, and report generation. In the aspect of software system structure, it is a complete computer aided product innovation design system to fully support the problem definition, analysis and solution to the whole process of report generation in product innovation design to a certain extent. In the aspect of software function module design, the application process of standard solution and scientific effect knowledge in product innovation design is discussed, and the algorithm flow of applying standard solution is improved. The application process of standard solution is systematized and operable, and the function of semantic extension based on function and synonym discrimination in scientific effect knowledge base is realized by using XML technology, which improves the recall and precision of knowledge. In the aspect of knowledge base system design, TRIZ knowledge tool and patent document knowledge are used as the source of innovation knowledge, including innovation principle knowledge base, standard solution knowledge base, The functional science effect knowledge base and the engineering design case base constitute the innovative design knowledge base system. The knowledge in the software is presented in the form of multimedia such as text, animation, picture and so on, which provides the designers with the innovative knowledge in the multi-disciplinary field. Easy to master and use by designers. Finally, the paper introduces and tests the operation and operation process of each module of software system with the examples of washing machine water saving innovation design and fan noise reduction innovation design, printer patent retrieval and technology maturity prediction, knowledge base management as an example. The corresponding innovative schemes are given to verify the correctness and effectiveness of the system.
