TRIZ理论在iNPD产品创新设计中的应用

Application of TRIZ Theory in iNPD Product Innovation Design

目的在注重以用户为中心和产品创新设计的背景下,找到一种新的设计方法,将TRIZ理论应用于以用户为中心的iNPD方法中,并进行优化。方法以粉末式喷剂药瓶的改良设计为例,对新的设计方法进行验证。在iNPD方法的识别机会阶段,确定了药瓶使用的有效性,提出对目标产品的定义;应用TRIZ得到了问题的有效解,从而确定了最优解;对产品进行细节设计,得到完整的设计方案。结果应用改良的iNPD设计方法,对粉末式喷剂药瓶进行了改良设计,达到了最初的设计目标。结论证明基于TRIZ理论的改良的iNPD设计方法是有效的,是一种创新的产品设计方法。

The work aims to find a new design method in the background of emphasizing the focus on users and product innovation, apply the TRIZ theory in the user-centered iNPD method and optimize the method. With the improved design of powder spray bottle as an example, the new design method was verified. In the identification opportunity phase of iNPD method, the effectiveness of the bottle was determined and the definition of target product was proposed. TRIZ was applied to obtain the efficient solution to the problem, thus determining the optimal solution. The detailed design of the product was carried out to obtain the complete design proposal. The improved iNPD design method was applied to improve the design of the powder spray bottle to achieve the initial design goal. The result shows that the improved iNPD design method based on TRIZ theory is effective and it is an innovative product design method.
