Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If charging current is increased to improve charging speed, then productivity is improved, but reliability deteriorates due to device deterioration and damage
Solution Approach 1:
The patent implements a feedback mechanism where sensor signals continuously monitor charging parameters (temperature, current, voltage) and the determination unit compares these signals with standard data. When deviations exceed allowable differences, the system automatically adjusts or stops charging, creating a closed-loop control system that prevents device damage while maintaining efficient charging operations
Solution Approach 2:
The system dynamically changes charging parameters (current, voltage, temperature) based on real-time sensor feedback. By adjusting these parameters according to device state and environmental conditions, the system optimizes charging speed while preventing excessive values that would cause deterioration, thus resolving the contradiction between productivity and reliability
2Reliability
If sensor monitoring and determination units are added to improve reliability, then device reliability is improved, but device complexity increases
Solution Approach 1:
The determination unit is designed to perform multiple functions: comparing sensor signals with standard data, determining whether deviations exceed allowable differences, and controlling charging operations. This multi-functional design reduces the need for separate dedicated components for each function, thereby improving reliability while minimizing the increase in device complexity
