Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If voltage modifiers (buck and boost converters) are used to adjust voltage levels, then voltage compatibility is improved, but device complexity increases
Solution Approach 1:
The patent introduces voltage modifiers (buck and boost converters) as intermediary components between the external power source and the battery. These mediators transform the voltage from the power source into the required voltage for battery charging, resolving the voltage compatibility issue while managing the added complexity through structured electrical pathways.
Solution Approach 2:
The charging device is segmented into distinct electrical pathways: a charging pathway for charging the supplemental battery, a discharge pathway for charging the mobile device, and a bypass pathway for direct charging. Each pathway contains appropriate voltage modifiers, allowing independent optimization of voltage conversion in each segment without affecting the entire system.
2Adaptability or versatility
If multiple electrical pathways (charging, discharge, bypass) are implemented, then charging flexibility is improved, but device complexity increases
Solution Approach 1:
The system is divided into three separate electrical pathways: charging pathway (external power to supplemental battery), discharge pathway (supplemental battery to mobile device), and bypass pathway (external power directly to mobile device). This segmentation allows each pathway to be independently controlled and optimized, providing charging flexibility while managing complexity through modular design.
Solution Approach 2:
The controller dynamically switches between different electrical pathways based on the charging state of the supplemental battery and the power availability. When the supplemental battery is charged, the discharge pathway is activated; when external power is available and battery is not fully charged, the charging or bypass pathway is used, providing adaptive charging flexibility.
3Productivity
If voltage modifiers are used to reduce voltage for battery charging, then charging efficiency is improved, but energy loss increases
Solution Approach 1:
The patent uses buck converters to change the voltage parameter from the external power source to a level suitable for battery charging. By adjusting the voltage parameter through controlled electromagnetic induction, the system achieves efficient power transfer while minimizing energy loss compared to unregulated voltage conversion.
Solution Approach 2:
The controller monitors the charging process and adjusts the operation of voltage modifiers in real-time. By implementing feedback control, the system optimizes the voltage conversion process, maintaining high efficiency while minimizing energy losses during the charging operation.
