Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional charging systems are used, then device functionality is maintained during charging, but charging speed is slow and power loss occurs
Solution Approach 1:
The charging system is segmented into two independent paths: a direct charging path that bypasses device electronics for high-speed charging, and an indirect path through the inductive charger for maintaining device functionality. This segmentation allows the system to achieve fast charging without power loss by isolating the charging current from the device's electronic components.
2Productivity
If direct charging path is used, then charging efficiency is improved, but device functionality cannot be maintained during charging
Solution Approach 1:
The system dynamically switches between two charging modes based on operational requirements. When fast charging is needed and device functionality can be suspended, the direct charging path is activated for high efficiency. When device functionality must be maintained, the system transitions to the indirect inductive charging path, allowing the device to remain operational during charging.
3Adaptability or versatility
If multiple charging components are implemented, then charging flexibility is improved, but device complexity increases
Solution Approach 1:
The input power component serves multiple functions: it receives power for both direct charging and inductive charging paths, and it isolates charging power from device electronics. This multi-functionality reduces the need for separate dedicated components, thereby managing complexity while providing charging flexibility through multiple paths.
