Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional mouse pad device is used, then the area is sufficient for keyboard and mouse devices, but the device cannot provide continuous power source for wireless devices
Solution Approach 1:
The patent divides the power transmission system into multiple independent secondary resonant circuits (first secondary resonant circuit, second secondary resonant circuit, etc.), each capable of independently receiving and transmitting wireless power. This segmentation allows the system to provide power to multiple devices simultaneously while maintaining manageable complexity in each individual circuit module.
Solution Approach 2:
The mouse pad device is designed with multiple secondary resonant circuits that can serve different functions: some circuits provide power to mouse devices, others to keyboard devices, and they can operate independently or in combination. This multi-functionality enables a single mouse pad to support various wireless devices with different power requirements.
2Ease of operation
If wireless power transmission is added to the mouse pad device, then convenient power supply is achieved, but the device structure becomes more complex
Solution Approach 1:
The patent combines multiple secondary resonant circuits within a single mouse pad body, integrating power transmission functionality into the existing mouse pad structure. By merging these circuits into one unified device with a common control unit, the system achieves wireless charging convenience while managing structural complexity through integration rather than separate components.
Solution Approach 2:
The control unit acts as an intermediary that manages power distribution from the external wireless power supply to multiple secondary resonant circuits. It coordinates which circuits are active, monitors power transmission status, and adjusts operation accordingly, thereby simplifying the overall system control while enabling complex multi-device power supply functionality.
