Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless charging is implemented with high power transmission, then charging efficiency is improved, but temperature increase occurs due to excessive current
Solution Approach 1:
The controller continuously monitors the current flowing through the conductive pattern and compares it against a predetermined threshold. When the current exceeds the threshold, the controller automatically adjusts the input current to prevent overheating, creating a closed-loop feedback system that balances charging efficiency with temperature control
Solution Approach 2:
The system dynamically changes the current parameter based on monitored conditions. By adjusting the input current to the conductive pattern based on real-time monitoring and threshold comparisons, the system optimizes power transmission while preventing temperature increase
2Ease of operation
If connection ports are exposed for charging, then ease of operation is improved, but contamination risk increases
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless charging system using electromagnetic induction. The conductive pattern generates an electromagnetic field that induces current in the wireless power receiver, eliminating the need for exposed physical connection ports while maintaining charging functionality
Solution Approach 2:
The conductive pattern acts as an intermediary that transfers power wirelessly through electromagnetic field generation. This intermediary mechanism enables power transmission without direct physical contact, preventing contamination while facilitating easy operation
