1Productivity
If 5G functions and multiple frequency bands are operated simultaneously, then communication performance and data throughput are improved, but heat generation increases significantly causing overheating issues
Solution Approach 1:
The patent segments the heat dissipation function into multiple independent heating elements distributed at different positions within the terminal. Each heating element can be independently controlled to heat specific localized areas, enabling targeted heat dissipation to different regions of the battery or electronic components based on real-time temperature monitoring, thus addressing overheating in high-performance 5G operations without requiring uniform heating across the entire device.
Solution Approach 2:
The patent implements a feedback control system where temperature sensors continuously monitor the temperature of electronic components and battery, and this temperature information is fed back to the control circuit. The control circuit adjusts the power supplied to heating elements based on the feedback, dynamically optimizing heat dissipation to maintain safe operating temperatures during high-throughput 5G communication while preventing overheating.

If passive heat dissipation materials are used, then heat dissipation is achieved, but the heat dissipation effect is insufficient and energy efficiency is low
Solution Approach 1:
The patent transitions from static passive heat dissipation materials to dynamic active heat dissipation using controllable heating elements. The system can dynamically adjust the heating intensity and distribution based on real-time temperature conditions and operational requirements, enabling adaptive heat management that improves heat dissipation effectiveness while optimizing energy consumption compared to continuous operation of passive materials.
Solution Approach 2:
The patent changes the physical state and thermal parameters of heat dissipation materials through controlled heating. By adjusting the temperature parameters of heating elements based on real-time feedback, the system can optimize the thermal conductivity and heat transfer characteristics of materials, achieving better heat dissipation performance with improved energy efficiency compared to fixed passive materials.
3Temperature
If traditional fan-based active heat dissipation is used, then heat dissipation is achieved, but the structure becomes complex and requires additional space
Solution Approach 1:
The patent merges the heat dissipation function with existing internal structures of the terminal by integrating heating elements into the battery or adjacent to electronic components. This combination eliminates the need for separate fan assemblies and complex airflow channels, achieving effective heat dissipation while maintaining a simple device structure and saving internal space for other components.
Solution Approach 2:
The patent implements a self-service heat dissipation system where the terminal uses its own internal heating elements and control circuits to manage heat without requiring external fan components. The system autonomously monitors temperature and activates heating elements as needed, providing heat dissipation functionality using only the device's own resources, thereby reducing structural complexity and eliminating the need for additional space-consuming fan assemblies.
