Engineering Contradiction Analysis
1Productivity
If charging power is increased to improve charging speed, then charging efficiency is improved, but heat generation increases and may cause temperature to exceed safe operating ranges
Solution Approach 1:
The patent implements dynamic heat dissipation control by adjusting fan speed based on real-time temperature monitoring. The controller receives temperature data from detection modules and dynamically adjusts the working state of the heat dissipation device, transitioning from static to dynamic operation to match varying charging power levels and temperature conditions.
Solution Approach 2:
The patent employs a feedback mechanism where temperature detection modules continuously monitor device temperature and feed this information to the controller. The controller then adjusts the heat dissipation device accordingly, creating a closed-loop control system that responds to temperature changes and maintains safe operating temperatures during high-power charging.
2Temperature
If heat dissipation device operates at high power continuously to maintain temperature, then temperature control is improved, but energy consumption increases
Solution Approach 1:
The patent applies partial action by operating the heat dissipation device at varying power levels rather than continuous maximum power. The controller adjusts fan speed to provide only the necessary heat dissipation required at each moment, avoiding excessive energy consumption while maintaining adequate temperature control through demand-based operation.
Solution Approach 2:
The patent implements periodic adjustment of heat dissipation power based on temperature feedback cycles. The system continuously monitors temperature and adjusts heat dissipation in periodic intervals, transitioning between different power states as needed rather than maintaining constant high-power operation, thereby reducing overall energy consumption while preserving temperature stability.
