Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple chargers are incorporated to handle different charging scenarios, then adaptability to varying operating conditions is improved, but device size and cost increase
Solution Approach 1:
The patent implements a single charger circuit that can operate in multiple charging modes (charge pump mode with different conversion ratios, direct charger mode, bypass mode) to handle various charging scenarios including wired and wireless charging, single-cell and multi-cell batteries, thereby achieving multi-functionality without increasing device size
Solution Approach 2:
The charger dynamically switches between different operating modes based on real-time operating conditions such as temperature and load requirements, enabling the same charger circuit to adapt to varying charging scenarios through mode selection rather than requiring multiple fixed-function chargers
