Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging is performed using electromagnetic induction or magnetic resonance, then wireless charging capability is achieved, but the electronic apparatus must be located close to the charging apparatus
Solution Approach 1:
The patent changes the fundamental parameter of wireless power transmission by using RF signals instead of electromagnetic induction or magnetic resonance. This allows power to be transmitted over much longer distances while maintaining charging capability, resolving the contradiction between wireless charging ease of operation and charging distance limitations.
2Device complexity
If one wireless charging apparatus charges only one electronic apparatus, then charging simplicity is maintained, but the ability to charge multiple devices simultaneously is limited
Solution Approach 1:
The patent enables the wireless charging apparatus to serve multiple functions by allowing it to charge multiple electronic apparatuses simultaneously using RF signals. The system can identify and power multiple devices at once, transforming a single-function charger into a multi-functional device that maintains simplicity while increasing productivity.
3Length of moving object
If RF signal intensity is increased to charge devices from a distance, then charging range is improved, but power consumption and potential harm to humans increases
Solution Approach 1:
The patent implements a feedback mechanism where the system identifies the location of electronic apparatuses and adjusts RF signal transmission accordingly. By continuously monitoring device positions and charging status, the system optimizes signal intensity to maintain effective charging distance while minimizing unnecessary RF exposure to humans, thus resolving the contradiction between charging range and safety.
