Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wired connections are used for power delivery, then power delivery reliability is ensured, but user convenience and safety are reduced due to tripping hazards and connection requirements
Solution Approach 1:
The patent replaces the mechanical wired connection system with an electromagnetic wireless power transmission system. The transmitting antenna generates electromagnetic signals that carry power to receiving antennas in electronic devices, eliminating the need for physical plugs and cables. This substitution maintains power delivery reliability through controlled electromagnetic coupling while dramatically improving convenience and safety by removing tripping hazards and connection requirements.
Solution Approach 2:
The patent introduces electromagnetic signals as an intermediary medium to transfer power between the power source and electronic devices. The transmitting antenna converts electrical power into electromagnetic signals, which then propagate through space to receiving antennas that convert them back to electrical power. This intermediary approach enables wireless power transfer while maintaining controlled and reliable energy delivery.
2Ease of operation
If wireless power transmission is implemented, then convenience and safety are improved, but power delivery capability for high-power devices is insufficient
Solution Approach 1:
The patent combines multiple transmitting antennas into a coordinated array system that works together to deliver power to multiple devices simultaneously. By merging the capabilities of individual antennas and coordinating their operation through control units, the system achieves high power delivery capability suitable for modern multimedia devices while maintaining the convenience and safety benefits of wireless transmission.
Solution Approach 2:
The patent employs dynamic control mechanisms where control units continuously adjust the operation of transmitting antennas based on real-time conditions such as device positions, power requirements, and signal strength. This dynamic adaptation enables the system to optimize power delivery for high-power devices while maintaining convenience and safety through automated adjustment rather than fixed configurations.
3Ease of operation
If multiple devices are charged simultaneously, then user convenience is improved, but power distribution efficiency and control become more complex
Solution Approach 1:
The patent segments the power distribution system into independent transmitting antenna units, each capable of being controlled individually by separate control units. This segmentation allows the system to manage multiple devices simultaneously by assigning specific antenna segments to specific devices or groups of devices, simplifying the overall control complexity while maintaining multi-device charging convenience.
Solution Approach 2:
The patent designs the transmitting antenna and control unit system to be universal and multi-functional, where each antenna unit can serve multiple devices and each control unit can manage multiple antennas. This universality enables efficient power distribution to multiple devices simultaneously while avoiding the need for separate dedicated systems for each device, thereby reducing overall system complexity.
