Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a fixed charging voltage is used, then the charging process is simple, but energy loss increases and battery life decreases
Solution Approach 1:
The charging voltage is dynamically adjusted based on the real-time battery voltage of the earphones. The charging box acquires communication data packets containing battery voltage information and adjusts the charging voltage accordingly, transitioning from a fixed voltage approach to a dynamic adaptive approach that reduces energy loss while extending battery life.
Solution Approach 2:
The charging voltage parameter is changed dynamically during the charging process. By monitoring the battery voltage and adjusting the charging voltage in real-time, the system optimizes the charging parameters to minimize energy loss and maximize battery longevity without significantly increasing system complexity.
2Productivity
If the charging box capacity is increased to charge more times, then the number of charging times increases, but the size of the charging box increases
Solution Approach 1:
The patent converts the previously harmful energy loss into a beneficial outcome by implementing dynamic voltage adjustment. By optimizing the charging voltage based on real-time battery voltage, the system reduces energy waste during charging, which directly increases the number of charging cycles the box can provide without needing to increase its capacity or size.
