需要设计在产品切换时，能够结合同类的型产品曾经出现过的问题进行预防性管

When the product needs to be designed to switch, capable of binding to the same kind of products have appeared in the preventive management issues <br>need to optimize the design of products change the process and shorten the time to improve the design issues <br>need to improve assembly and test equipment design change verification process <br>required to associate design change review mechanism ; <br>the need to improve assembly and test equipment design change verification process <br>required at the time of product optimization technology can consider whether a more advanced product structure to support the upgrading of products.

Need to design in the product switching, can be combined with similar products have experienced problems for preventive management<br>Need to optimize the design product change process and reduce design problem improvement time<br>Need to improve the design change assembly test installation verification process<br>Need to establish an association design change review mechanism;<br>Need to improve the design change assembly test installation verification process<br>Technology is needed to be able to consider whether the product structure can support product replacement in the process of product optimization.

It needs to be designed to be able to carry out preventive management in combination with problems of similar products during product switching<br>Need to optimize design product change process and shorten design problem improvement time<br>Need to improve the verification process of final assembly and trial assembly for design change<br>It is necessary to establish a review mechanism for related design changes;<br>Need to improve the verification process of final assembly and trial assembly for design change<br>It needs technology to be able to consider whether the product structure can support the product upgrading in a more advanced way during product optimization.<br>
