Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If single charging circuit (wired or wireless) is used, then device simplicity is maintained, but charging power is limited
Solution Approach 1:
The patent combines multiple charging circuits (wired charging circuit and at least two wireless charging circuits) into a single electronic device, allowing them to work together to provide higher charging power than any single circuit could achieve alone. The battery management circuit coordinates the combined output of these circuits to charge the battery simultaneously.
Solution Approach 2:
The charging system is segmented into multiple independent charging circuits (wired charging circuit, first wireless charging circuit, second wireless charging circuit) that can operate independently or in combination. Each circuit is a separate module that can be individually controlled and managed by the battery management circuit.
2Productivity
If charging power is increased to improve charging rate, then charging speed improves, but heating increases
Solution Approach 1:
The charging current is divided and distributed across multiple charging circuits (wired charging circuit and multiple wireless charging circuits) through the battery management circuit. By segmenting the total charging current into parallel paths, the current density in each individual circuit is reduced, thereby reducing Joule heating and thermal generation in each circuit while maintaining high total charging power.
