Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless charging power is increased to improve charging speed, then charging speed is improved, but temperature of the transmitter and terminal increases causing safety concerns
Solution Approach 1:
The patent implements a feedback control system where temperature sensors continuously monitor the temperatures of both the wireless charging transmitter and the terminal. Based on the detected temperature values, the control system dynamically adjusts the charging power output. When temperatures approach predefined thresholds, the system automatically reduces power or pauses charging, preventing overheating while maintaining optimal charging speed during normal operation.
2Reliability
If temperature control measures are implemented to prevent overheating, then safety is improved, but charging speed may be reduced
Solution Approach 1:
The patent employs dynamic temperature control where the charging parameters are continuously adjusted based on real-time temperature conditions. The system transitions between different charging states (normal charging, reduced power, paused) depending on temperature levels, allowing maximum charging speed when temperatures are safe while ensuring safety when temperatures rise, thus optimizing both speed and safety throughout the charging process.
3Temperature
If active cooling mechanisms are added to manage temperature, then temperature control is improved, but device complexity increases
Solution Approach 1:
The patent implements a self-regulating temperature control system that uses temperature sensors and control circuits to automatically monitor and adjust charging parameters without requiring external intervention or complex active cooling mechanisms. The system self-adjusts power output based on detected temperature conditions, eliminating the need for additional cooling hardware while maintaining effective temperature management.
