Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power transmitting coils are integrated into hand-operated input devices, then wireless charging convenience is improved, but device complexity increases
Solution Approach 1:
The patent combines the wireless power transmitting coil with the hand-operated input device (mouse, keyboard, or touchpad) into a single integrated unit. The coil is embedded within the device housing, allowing the input device to simultaneously perform its primary function and provide wireless charging capability, thereby eliminating the need for separate charging equipment and improving charging convenience.
2Reliability
If the transmitting coil is disposed within the input device platform, then magnetic coupling is improved, but the available space for other components is reduced
Solution Approach 1:
The patent utilizes the vertical dimension by disposing the transmitting coil at an angle relative to the planar surface of the input device platform. This angular orientation allows the coil to achieve optimal magnetic coupling with wearable devices placed on the platform while minimizing the horizontal space occupied by the coil structure, thereby resolving the conflict between magnetic coupling effectiveness and available component space.
