Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If wireless power transmission is implemented without proper alignment mechanisms, then the system structure remains simple, but power transmission efficiency deteriorates due to limitations in coupling coefficient
Solution Approach 1:
The guide member is pre-configured with an inclined surface that automatically guides the wireless terminal into the correct position relative to the transmission coil. This preliminary alignment action ensures optimal coupling coefficient before power transmission begins, resolving the contradiction by improving power transmission efficiency through pre-positioning without requiring complex real-time adjustment mechanisms.
2Object-affected harmful factors
If wireless power transmission operates without thermal management, then device complexity remains low, but harmful thermal effects increase during charging
Solution Approach 1:
A heat sink is introduced as an intermediary thermal management component between the transmission coil and the environment. The heat sink absorbs and dissipates heat generated during wireless power transmission, reducing harmful thermal effects on the wireless terminal and supporter. This resolves the contradiction by effectively managing thermal effects through a dedicated heat dissipation structure without requiring complex active cooling systems.
3Loss of energy
If the wireless terminal is not properly stabilized during charging, then the device structure remains simple, but power transmission efficiency deteriorates due to misalignment
Solution Approach 1:
The guide member with inclined surface performs preliminary stabilization by automatically positioning the wireless terminal in the correct orientation and location on the supporter. This pre-positioning ensures optimal alignment between the transmission coil and the terminal's receiving coil throughout the charging process, maintaining power transmission efficiency without requiring complex active stabilization mechanisms.
