Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the transmission rate is increased in 5G network, then the data throughput is improved, but the terminal temperature increases excessively
Solution Approach 1:
The patent implements dynamic adjustment of transmission rate based on real-time temperature monitoring. The network device receives temperature information from the terminal and dynamically modifies the transmission rate accordingly, making the system adaptive rather than static. This resolves the contradiction by allowing high throughput when temperature is acceptable while preventing overheating through rate reduction when temperature exceeds thresholds.
Solution Approach 2:
The patent changes the transmission rate parameter in response to temperature parameter changes. When the terminal temperature exceeds a first threshold, the network device reduces the transmission rate to allow heat dissipation. When temperature drops below a second threshold, the rate is restored. This parameter coupling resolves the contradiction by making throughput conditional on thermal state.
2Temperature
If the transmission rate is reduced to lower terminal temperature, then the temperature is controlled, but the network throughput decreases
Solution Approach 1:
The patent implements periodic monitoring of terminal temperature and periodic adjustment of transmission rate. The terminal continuously monitors its temperature and reports to the network device, which periodically adjusts the rate based on received temperature information. This periodic control allows the system to maintain high throughput during normal operation while temporarily reducing rate only when necessary for thermal management.
Solution Approach 2:
The patent establishes a feedback loop where the terminal monitors its temperature and sends temperature information back to the network device, which then adjusts the transmission rate accordingly. This closed-loop feedback system resolves the contradiction by ensuring rate reduction occurs only when actually needed for thermal control, rather than permanently reducing throughput.
3Temperature
If rate reduction information is sent immediately when temperature exceeds threshold, then temperature control is achieved, but network connection stability deteriorates
Solution Approach 1:
The patent sends rate reduction information proactively when temperature exceeds the first threshold, before severe overheating occurs. By taking preliminary action at the first sign of excessive temperature, the system prevents thermal runaway while maintaining connection stability. The network device prepares for rate adjustment in advance rather than waiting for critical temperature conditions.
Solution Approach 2:
The patent implements dynamic threshold-based control where the transmission rate is adjusted based on temperature relative to predefined thresholds. When temperature exceeds the first threshold, rate is reduced; when it falls below the second threshold, rate is restored. This dynamic hysteresis control prevents oscillation and maintains connection stability while effectively managing temperature.
4Temperature
If the transmission rate is continuously reduced to maintain low temperature, then thermal management is improved, but user experience and network performance deteriorate
Solution Approach 1:
The patent uses feedback-based control where the terminal continuously monitors temperature and reports to the network device, which adjusts rate only when necessary. This ensures that transmission rate is maintained at high levels during normal operation for optimal user experience, while temporarily reducing rate only when temperature actually exceeds thresholds, thus avoiding unnecessary performance degradation.
Solution Approach 2:
The terminal autonomously monitors its own temperature and sends reports to the network device, which then self-adjusts the transmission rate based on received information. This self-service mechanism ensures thermal management is handled automatically without manual intervention, maintaining good user experience while preventing overheating through intelligent, condition-based rate adjustment.

AI summary
A method for reducing terminal temperature includes: connecting to a first network; and monitoring a chip temperature of a terminal, and sending rate reduction information to a network device when the chip temperature is greater than a first predetermined threshold, and the rate reduction information being used to trigger reduction in a transmission rate between the network device and the terminal. As such, the terminal temperature can be reduced by reducing the transmission rate while maintaining the network connection, and user experience can be improved.
