Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all inductive charging units in the mouse pad work continuously, then the mouse pad can charge a mouse placed anywhere on its surface, but energy is wasted on parts that are not near the mouse
Solution Approach 1:
The mouse pad is divided into multiple independent inductive charging units, each capable of detecting and charging independently. This segmentation allows only the necessary units near the mouse to consume energy, while distant units remain inactive, resolving the contradiction between broad charging coverage and energy efficiency.
Solution Approach 2:
The system dynamically adjusts the working state of each inductive charging unit based on real-time detection of mouse proximity. When a mouse is detected near a charging unit, that unit activates; when no mouse is present, it deactivates. This dynamic adaptation resolves the contradiction by making the charging system flexible and responsive to actual usage conditions.
2Loss of energy
If the mouse pad detects and activates only nearby charging units, then energy is saved, but the system complexity increases due to detection and control mechanisms
Solution Approach 1:
The detection and control functions are merged into a single integrated control unit that manages all inductive charging units. This unified approach simplifies the overall system architecture by eliminating the need for separate detection and control circuits in each charging unit, thereby reducing total system complexity while still achieving energy savings through selective activation.
Solution Approach 2:
The control unit continuously monitors the charging status and proximity of the mouse, using this feedback information to dynamically adjust which charging units remain active. This feedback mechanism enables automatic optimization of energy consumption without requiring complex manual control systems, as the system self-regulates based on real-time conditions.

AI summary
An intelligent wireless power-supplying mouse pad is applied to a wirelessly-charged mouse. The intelligent wireless power-supplying mouse pad includes a mouse pad body, a plurality of inductive charging units and a control unit. Each of the inductive charging units includes an inductive charging coil and an inductive charging loop. When the inductive charging coil and the wirelessly-charged mouse form an inductive coupling to perform a wireless charging to the wirelessly-charged mouse, the inductive charging loop detects a charging current of the inductive charging coil to obtain a charging status signal. The inductive charging loop sends the charging status signal to the control unit. Based on the charging status signal, the control unit controls a magnitude of an output energy outputted from the inductive charging loop to the inductive charging coil to control an emitting power of the inductive charging coil.
