programing:
use triz matrix find the contradiction and think the solution use axiomatic design figure out customer needs,functional requirements，design parameters,process variables. use triz matrix find the contradiction and think the solution use the tools I can find to solve the problem.
output：拥有USB接口的台灯 坏掉的电池
customer needs：find the problem of the desk lamp and design a new structure to mend it.
functional requirements:portable source, stable voltage, battery charging
design parameters:contradiction matrix , axiomatic design.
process variables:the voltage, the link of the
'''contradiction matrix''':

通过人类已经发明的技术手段结合我寝室的自身条件，经过综合分析后，我认为加装一个USB接口，把充电宝当做台灯的移动电源能解决上述矩阵中每一个交点的问题。
