Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless charging devices are limited to one charging operating mode and power class, then device complexity is reduced, but adaptability and versatility deteriorate
Solution Approach 1:
The charging device is designed with multiple charging operating modes (first charging operating mode and second charging operating mode) that can be selected based on different battery units and user requirements. The control electronics system automatically detects battery parameters and selects the appropriate charging mode, enabling one device to serve multiple functions and different battery types without requiring separate charging devices for each scenario.
2Reliability
If wireless charging devices transmit electrical energy continuously, then productivity is improved, but reliability deteriorates due to lack of adaptability
Solution Approach 1:
The charging device dynamically adjusts its operating parameters by switching between different charging operating modes based on real-time battery parameters detected by the control electronics system. The system can transition from continuous energy transmission to intermittent transmission, adjust power levels, and modify charging duration according to the specific battery unit being charged, thereby optimizing both reliability and charging efficiency.
3Adaptability or versatility
If a charging device is designed for a defined power class, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The charging device incorporates a control electronics system that can adjust power transmission parameters dynamically. By detecting battery parameters such as capacity, voltage, and current requirements, the system automatically modifies charging power levels and transmission characteristics to match the specific battery unit, enabling interoperability across different power classes without requiring multiple dedicated charging devices.
