Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If solar energy is used as power source, then the notebook computer can be charged externally, but the charging is limited by weather conditions
Solution Approach 1:
The patent transitions from solar energy charging to wireless charging using electromagnetic induction, fundamentally changing the energy transfer parameter from light-dependent to field-dependent. The wireless charging device uses a first coil induction module while the detection device uses a second coil induction module, enabling charging without weather constraints and improving charging reliability while maintaining external charging capability
Solution Approach 2:
The patent replaces the mechanical/optical solar charging system with an electromagnetic wireless charging system. Instead of using solar panels that require light exposure, the system uses electromagnetic field induction between coil modules to transfer energy, eliminating weather dependency while preserving external charging functionality
2Reliability
If wireless charging with coil induction modules is used, then weather-independent charging is achieved, but device complexity increases
Solution Approach 1:
The wireless charging system is designed with multi-functionality to reduce overall system complexity. The detection device with the second coil induction module can both detect the wireless charging device and receive power wirelessly, combining detection and charging functions in one component. This universal approach allows the system to achieve weather-independent charging while minimizing the number of separate components needed
