Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If higher transmission power is used to compensate for low transmission efficiency in wireless energy charge, then energy charge quality is improved, but interference with coexisting wireless communication systems increases
Solution Approach 1:
The patent implements a feedback mechanism where the terminal measures the state of wireless energy charge and transmits this information back to the base station. The base station uses this feedback to dynamically adjust transmission parameters, optimizing energy charge quality while minimizing interference with coexisting communication systems through adaptive control.
2Reliability
If detailed feedback information reporting is implemented for wireless energy charge state, then energy charge control quality is improved, but device complexity increases
Solution Approach 1:
The patent reuses existing communication protocols and channels for feedback reporting, making the feedback mechanism multi-functional by serving both energy charge monitoring and communication coordination purposes. This approach improves control quality without proportionally increasing device complexity, as the same infrastructure handles multiple functions.
