Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high power and current are used for rapid charging, then charging speed is improved, but device complexity and thermal management requirements increase
Solution Approach 1:
The patent extracts the charging circuit functionality from the portable electronic device and relocates it to an external charging station. The battery pack includes exposed terminals that connect directly to the charging station, bypassing the need for internal charging circuits in the portable device. This extraction resolves the contradiction by enabling high-power rapid charging without increasing the complexity of the portable device's charging circuitry.
2Loss of time
If high power charging is implemented, then charging time is reduced, but thermal management requirements increase
Solution Approach 1:
The patent moves the power conversion and thermal management functions from the portable device to the external charging station. By using direct current coupling between the charging station and battery pack terminals, the system enables high-power charging while the charging station handles the thermal management burden, thus reducing charging time without compromising the portable device's thermal management capabilities.
3Reliability
If internal charging circuits are used, then charging control is improved, but device size and component requirements increase
Solution Approach 1:
The patent extracts the charging control functionality from the portable electronic device and places it in the external charging station. The battery pack serves as an intermediate energy storage device with simple terminal connections, eliminating the need for complex internal charging circuits in the portable device. This reduces the device volume while maintaining charging control through the external station.
4Productivity
If direct charging terminals are exposed, then charging efficiency is improved, but safety risks increase
Solution Approach 1:
The patent introduces a protective cover as an intermediary element between the exposed charging terminals and the external environment. The cover includes recessed portions that align with the terminals, providing physical protection while allowing direct electrical contact during charging. This intermediary structure maintains charging efficiency through direct terminal contact while mitigating safety risks from exposed conductors.
