摘要

针对传统面授课堂上因使用粉笔导致室内粉尘含量过高而不利于人体健康的问题

本文运用可拓学和基于发明问题解决理论(Theory of the Solution of Inventive Problems

TRIZ)的计算机辅助创新技术对已有的无尘黑板专利产品创新设计。检索并选择无尘黑板专利作为研究对象

利用计算机辅助创新软件Goldfire的专利规避模块完成功能分析

建立功能模型

判断模型中的问题功能并用可拓基元模型表达功能信息。确定规避路径后运用可拓变换方法对被替换组件进行规避

获得可拓规避模型。结合TRIZ求解工具与发散树对规避问题进行求解获得解决方案并判断其可行性。通过该流程的应用为其他产品的专利规避提供借鉴。

Abstract

In view of the problem that the indoor dust content is too high due to the use of chalk in the traditional face-to-face classroom

Extenics and computer aided innovation technology based on the theory of the solution of inventive problems (TRIZ) are used to innovate the existing dust-free blackboard products. Searching and selecting the dust-free blackboard patent as the research object

using the patent evasion module of computer-aided Innovation Software goldfire to complete the function analysis

a function model is established

the problem function in the model judged

and the function information expressed with the extension basic element model. After determining the circumvention path and using the extension transformation method to evade the replace components

the circumvention model is obtained. Combined with TRIZ solution tool and the divergence tree

the solution is obtained and its feasibility judged. The application of this process can provide reference for other products to design around patent.
