It is the critical point in product family design. Here a knowledge acquisition method was introduced based on scenario model and repository grid and attribute ordering table technology. This method acquired knowledge through providing product design cases to expert, and recording the means and knowledge used by the expert to describe and resolve problems. It used object to express design entity, used scenario to describe the design process, used Event-Condition-Action(ECA) nile to drive design process, and with the help of repository grid and attribute ordering table technology to acquire design knowledge. It' s a good way to capture explicit and implicit knowledge. And its validity is proved with respective examples.展开更多
为了探索产品概念设计的新思路,将情景引入产品概念设计过程中,提出一种基于情景和TRIZ的产品概念设计过程模型。明确产品情景的构成和关键要素,形成产品情景作用信息的提取过程,通过关键情景要素类比发现产品概念设计可参考的原型产品...为了探索产品概念设计的新思路,将情景引入产品概念设计过程中,提出一种基于情景和TRIZ的产品概念设计过程模型。明确产品情景的构成和关键要素,形成产品情景作用信息的提取过程,通过关键情景要素类比发现产品概念设计可参考的原型产品,并根据预期情景信息与原型产品情景作用过程的匹配性发现问题,借助TRIZ(Theory of Inventive Problem Solving)工具求解问题,最后经汇总优化后获得创新的概念设计方案。利用所提方法形成一种气吸式枸杞采摘机的概念设计方案,从而验证了该方法的有效性。展开更多
