Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the number of input/output wires in the transmission/reception coil is increased, then the wireless power transmission capability is improved, but the connection process becomes more complicated and the durability decreases due to wire movement
Solution Approach 1:
The patent merges multiple input/output wires into a single integrated cable assembly. The cable fixing portion integrates multiple wire connection points and routing paths into one unified structure, reducing the number of separate connection operations required while maintaining the necessary electrical connections for enhanced power transmission
2Power
If the number of input/output wires in the transmission/reception coil is increased, then the wireless power transmission capability is improved, but the durability decreases due to wire movement
Solution Approach 1:
The cable fixing portion performs preliminary fixation of all input/output wires during the assembly stage. By pre-positioning and securing the wires in their proper locations before the coil begins operation, the structure prevents subsequent wire movement and wear, thereby maintaining durability even as power transmission capability increases
3Power
If the output amount of wireless power transmitted from the wireless power system is increased, then the power transmission capability is improved, but heat generated in the transmitting/reception coil increases, decreasing transmission efficiency
Solution Approach 1:
The patent introduces a heat dissipation member as an intermediary component between the coil windings and the external environment. This mediator structure facilitates efficient heat transfer from the high-power coil to the surrounding air or cooling system, enabling sustained high power transmission without excessive temperature rise that would reduce efficiency
4Power
If the output amount of wireless power transmitted from the wireless power system is increased, then the power transmission capability is improved, but heat generated in the transmitting/reception coil increases, decreasing transmission efficiency
Solution Approach 1:
The patent converts the harmful heat generated by high-power transmission into a manageable thermal flow. The heat dissipation member captures the waste heat and facilitates its controlled dissipation, transforming what would be energy loss into a controlled thermal management process that maintains transmission efficiency even at elevated power levels
