Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If voltage step-up and voltage step-down processes are used in charging, then charging can be performed on devices with different voltage requirements, but energy loss increases and charging efficiency decreases to 54%-78%
Solution Approach 1:
The patent extracts the voltage step-up circuit from the charged device and relocates it to the charging device. This eliminates the need for the charged device to perform both voltage step-up and step-down operations, thereby reducing energy loss while maintaining charging compatibility across different voltage requirements.
Solution Approach 2:
Instead of having the charged device perform voltage conversion (step-up then step-down), the patent inverts the approach by having the charging device perform the voltage step-up operation. This reversal eliminates redundant voltage conversion steps and associated energy losses.
