Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the power of the wireless charging device is increased, then the charging efficiency is improved, but the temperature increases more quickly and heat output becomes large
Solution Approach 1:
The patent implements dynamic fan rotation rate control based on real-time temperature monitoring during wireless charging. The control module adjusts the fan's rotation rate dynamically according to the detected temperature, allowing the system to maintain high charging power while effectively managing heat dissipation through adaptive fan speed adjustment.
2Reliability
If the fan rotation rate is increased to dissipate heat, then the heat dissipation efficiency is improved, but the noise increases and user experience deteriorates
Solution Approach 1:
The system dynamically adjusts fan rotation rate based on temperature conditions rather than operating at constant high speed. The control module monitors temperature in real-time and adjusts fan speed accordingly, maintaining effective heat dissipation while minimizing noise during low-temperature periods and only increasing fan speed when actually needed for thermal management.
Solution Approach 2:
The patent changes the operational parameters of the fan from fixed rotation rate to variable rotation rate based on temperature conditions. By adjusting the fan's rotation parameter dynamically according to temperature thresholds and charging power levels, the system achieves optimal balance between heat dissipation efficiency and noise reduction.
3Object-affected harmful factors
If the fan rotation rate is decreased to reduce noise, then the noise level is reduced, but the heat dissipation efficiency becomes insufficient
Solution Approach 1:
The control module implements dynamic adjustment of fan rotation rate based on real-time temperature monitoring. When temperature exceeds predefined thresholds during wireless charging, the system automatically increases fan speed to ensure adequate heat dissipation, while maintaining lower noise levels during normal operating conditions.
4Reliability
If constant fan operation is used for heat dissipation, then the heat dissipation is maintained, but energy is wasted and resources are not efficiently utilized
Solution Approach 1:
The system implements periodic temperature monitoring and conditional fan operation rather than continuous constant-speed operation. The control module activates the fan only when temperature thresholds are exceeded during wireless charging, and adjusts rotation rate periodically based on current thermal conditions, thereby eliminating energy waste during periods when cooling is not required.
Solution Approach 2:
The patent changes the fan operation from constant parameter (fixed rotation rate) to variable parameter (dynamic rotation rate adjustment). By modifying the fan's operational parameters based on real-time temperature and charging power conditions, the system achieves energy-efficient heat dissipation that activates cooling only when necessary.

Implementation Method 1
A charging device supporting a computing device includes a wireless charging device and a wired charging device. Compared with a wireless charging device, a wired charging device is poor in compatibility and universality because connectors must be matched between the wire and the device. The wireless charging device is charged in an electromagnetic induction mode with better compatibility
