基于可拓学的镍氢电池定制设计中矛盾问题求解

Solving Contradiction Problems Based on Extension Theory in the Customization Design of MH-Ni Battery

镍氢电池用途广泛,需要根据不同的应用需求定制设计相应性能的镍氢电池.在镍氢电池定制设计过程中,为了解决用户需求与工程技术特征的冲突问题,应用可拓学的矛盾问题处理方法建立镍氢电池不相容问题的可拓求解模型,通过可拓变换找出可拓求解模型中的核问题,计算变换后的相容度函数,识别出引起不相容问题的主要工程技术特征;通过改善这些工程技术特征,获得矛盾问题的可行优化方案.最终通过改进电池的切片毛刺和集耳形状、利用石墨烯取代导电炭黑试制出一种石墨烯镍氢电池,获得满足客户需求的高性能镍氢电池新产品.

MH-Ni batteries are used widely, and it is necessary to design MH-Ni battery in customization according to different user requirements. In the customization design process of MH-Ni battery, in order to solve the contradictory problems between user requirements and engineering metrics, the extension model of incompatible problems is established in the Extenics. The extension transformation is implemented into the extension model to find out the basic-elements. By calculating and validating the compatibility functions, some engineering metrics are recognized which caused the incompatible problems. Through improving tab＇s shape, we can obtain a feasible solution to the contradictory problems. Finally, a new product of MH-Ni battery, which meets the needs of customers, is obtained by improving the chip burr and the ear shape of the battery and using the graphite to replace the conductive carbon black to produce a kind of MH-Ni battery.
