Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power transmission is implemented, then mobility and convenience are improved, but power transmission efficiency deteriorates
Solution Approach 1:
The patent introduces a conductive pattern as an intermediary element that enables wireless power transmission while maintaining high efficiency. The conductive pattern acts as a mediator between the power source and external devices, allowing power transfer without direct wired connection while minimizing energy loss through optimized conductive design.
Solution Approach 2:
The patent employs parameter changes by adjusting voltage levels (converting high voltage to lower voltage) and utilizing different conductive patterns with varying properties to optimize power transmission efficiency. This allows the system to adapt transmission parameters to minimize energy loss while maintaining wireless convenience.
2Power
If multiple battery cells are used to provide higher voltage, then power output capability is improved, but device complexity increases
Solution Approach 1:
The patent divides the battery system into multiple individual cells rather than using a single complex high-voltage battery. Each cell operates independently at a lower voltage level, and the conductive pattern selectively connects these segmented cells to achieve the required total voltage, thereby reducing overall system complexity while maintaining high power output capability.
Solution Approach 2:
The patent implements dynamic connectivity where the conductive pattern can selectively connect different combinations of battery cells based on power requirements. This dynamic reconfiguration allows the system to adjust voltage output flexibly without requiring a fixed complex circuit design, simplifying the overall device architecture.
