Solution Overview

Problem

Electronic devices using 5G networks for high-speed data transfer are prone to overheating, leading to performance degradation and inconvenience due to increased heat production, especially during resource-intensive applications like gaming.

Innovation Solution

The electronic device switches between communication channels based on application execution status and temperature, dynamically adjusting between 5G and lower frequency bands (2G, 3G, 4G, LTE) to reduce heat production and maintain performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the electronic device communicates with the server via the 5G network, then the data rate is 20 times faster than 3G or 4G, but the electronic device overheats

Engineering Contradiction:
Improvedata rateVSAvoiddevice temperature
Core Design Contradiction:
SpeedVSTemperature

Solution Approach 1:

The patent implements dynamic network switching between 5G and lower frequency bands (2G, 3G, 4G, LTE) based on real-time temperature monitoring and application execution status. The system dynamically adjusts the communication channel to transition from high-speed 5G to lower-frequency bands when overheating is detected, and switches back to 5G when temperature normalizes, creating a dynamic adaptive mechanism that balances speed and thermal management

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operating parameters of the communication system by switching between different frequency bands and network generations. When temperature exceeds a threshold, the system changes from 5G (higher frequency, higher speed) to lower frequency bands (lower frequency, lower heat generation), thereby changing the operational parameters to resolve the contradiction between speed and temperature

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the electronic device uses 5G network for high-speed data transfer, then application performance is improved, but heat production increases causing performance degradation

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent implements a feedback mechanism where the processor continuously monitors temperature through temperature sensors and adjusts network selection based on real-time thermal conditions. The system feeds back temperature information to the network selection logic, creating a closed-loop control system that adapts network usage to thermal state, preventing heat-induced performance degradation while maintaining high productivity when thermal conditions permit

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system employs periodic temperature monitoring and threshold-based switching between 5G and lower frequency bands. The temperature is checked at regular intervals, and when thresholds are crossed, the system periodically switches network modes, creating a rhythmic adaptive behavior that maintains application performance while managing thermal accumulation

Inventive Principle:
Principle #19Periodic action

3Temperature

If the electronic device switches between communication channels based on temperature and application status, then heat generation is reduced, but system complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent makes the existing communication module and processor multi-functional by enabling them to perform both standard communication functions and thermal management functions. The same hardware components that handle data transmission are also utilized for temperature monitoring, network selection, and adaptive switching, thereby reducing overall system complexity while achieving heat generation reduction through multi-functional utilization of existing components

Inventive Principle:
Principle #6Universality (Multi-functionality)
