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 does not provide continuous power source functionality
Solution Approach 1:
The patent combines multiple resonant circuits (first primary resonant circuit, first secondary resonant circuit, second secondary resonant circuit) into a single mouse pad device, integrating wireless power transmission capabilities for both keyboard and mouse devices into one platform, thereby providing continuous power source functionality without requiring separate charging devices
Solution Approach 2:
The mouse pad device is designed to simultaneously support multiple functions: it serves as a workspace for keyboard and mouse devices while also providing wireless power transmission to both devices through multiple resonant circuits, making it a multi-functional integrated solution
2Ease of operation
If wired power supply is used for keyboard and mouse devices, then continuous power is provided, but user convenience and experience are reduced
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless electromagnetic power transmission system using resonant circuits, eliminating the need for physical plug-and-play connections while maintaining continuous power supply capability through inductive coupling between primary and secondary resonant circuits
3Adaptability or versatility
If a single resonant circuit is used for wireless charging, then device complexity is reduced, but the ability to charge multiple devices simultaneously is limited
Solution Approach 1:
The patent divides the wireless power transmission system into multiple independent resonant circuits: a first primary resonant circuit that can couple with either a keyboard or mouse device, and separate first and second secondary resonant circuits for receiving power, enabling flexible simultaneous or sequential charging of multiple devices through independent circuit operation
