Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the wireless charging mouse receives electromagnetic energy continuously, then the charging speed is improved, but the operational performance deteriorates when moving
Solution Approach 1:
The patent implements dynamic power switching that adjusts energy distribution based on real-time movement detection. When the mouse is stationary, the power switching circuit directs electromagnetic energy to the charging circuit for fast charging. When movement is detected, the circuit dynamically switches to prioritize operational power for the wireless transmission circuit, ensuring continuous operational performance while charging when appropriate
Solution Approach 2:
The system changes the operational parameters of the power switching circuit based on movement state. By detecting whether the mouse is moving or stationary, the control circuit adjusts the power distribution parameters dynamically, switching between charging mode and operational mode to optimize both charging efficiency and operational performance at different times
2Productivity
If the wireless charging mouse prioritizes charging when stationary, then the charging speed is improved, but the operational reliability deteriorates when moving
Solution Approach 1:
The patent employs feedback from the movement detecting circuit to the control circuit, which then adjusts power distribution accordingly. The movement detection provides real-time feedback about the operational state, enabling the system to respond appropriately by switching between charging and operational power modes, ensuring operational reliability is maintained when needed
Solution Approach 2:
The power switching circuit dynamically adapts its behavior based on real-time movement detection. When movement is detected, the system dynamically prioritizes operational power to maintain reliability. When stationary, it dynamically switches to charging mode to maximize charging speed, thus resolving the contradiction through dynamic adaptation
3Device complexity
If the wireless charging mouse uses fixed power distribution, then the device complexity is reduced, but the adaptability deteriorates across different usage scenarios
Solution Approach 1:
The patent implements a self-service power management system where the mouse automatically detects its own movement state and adjusts power distribution without user intervention. The movement detecting circuit monitors the operational state, and the control circuit autonomously switches between charging and operational modes, providing adaptability across different usage scenarios while keeping the user interface simple
Solution Approach 2:
The system transitions from fixed power distribution to dynamic power distribution based on movement state. The power switching circuit adapts its behavior dynamically, switching between charging mode and operational mode according to real-time detection, thereby achieving high adaptability across different usage scenarios
