三、改进方案的提出和评价 (一)提出改进方案 在功能评价的基础上,对价值低的产品和零件应给予改善。在此阶段,应回答: 1、除现有方案外,还有无其他方法实现要求的功能?2、这些方法的成本是多少? 一般地说,改善先从老产品的局部改起,如果这种改善还达不到预定目标,就应提出新的设计方案,以改变功能系统图。 下面首先分析局部改善的效果及其可能性:
III. Proposal and Evaluation of Improvement Schemes (I) Proposal of improvement programs Based on functional evaluation, products and parts with low value should be improved. At this stage, you should answer: 1. In addition to the existing solutions, are there any other ways to achieve the required functions? 2. What is the cost of these methods? Generally speaking, the improvements should first be made from the old products, if this If the improvement still falls short of the target, a new design proposal should be proposed to change the functional system map. The following is the first analysis of the effect of partial improvement and its possibilities:
