Innovation Solution
A middle frame assembly with a homothermal structure and radiating fin, where the contact area between the radiating fin and homothermal structure is adjustable, allowing for customizable heat dissipation based on power consumption levels and user interaction, utilizing a system of radiating sub-fins and elastic sheets controlled by a controller to optimize heat transfer and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a complete radiating fin is attached between the back cover and the middle frame, then heat dissipation is provided, but the heat dissipation requirements in different usage scenarios cannot be met
Solution Approach 1:
The radiating fin is divided into multiple independent radiating sub-fins that can be individually controlled. Each radiating sub-fin corresponds to different partition areas of the back cover, allowing selective activation based on heat generation patterns in different usage scenarios. This segmentation enables flexible heat dissipation adaptation without requiring a complete radiating fin structure.
Solution Approach 2:
The contact area between each radiating sub-fin and the homothermal structure is made adjustable through elastic sheets and driving components. This dynamic adjustment capability allows the system to optimize heat dissipation by increasing or decreasing contact area based on real-time temperature and usage conditions, resolving the contradiction between providing heat dissipation and adapting to different scenarios.
2Temperature
If the contact area between radiating fin and homothermal structure is fixed, then structure is simple, but heat dissipation cannot be optimized for different power consumption levels
Solution Approach 1:
The contact area between radiating sub-fins and homothermal structure is made dynamically adjustable through elastic sheets connected to driving components. This allows the system to optimize heat dissipation efficiency by increasing contact area when high power consumption generates excessive heat, while reducing contact area when cooling is not needed, balancing performance with structural simplicity.
Solution Approach 2:
The physical parameter of contact area is made changeable through the elastic sheet mechanism. By varying the contact area parameter between radiating sub-fins and homothermal structure, the system can adapt heat dissipation efficiency to match different power consumption levels and usage scenarios without requiring a completely different structural design.
3Temperature
If heat dissipation is increased, then temperature control is improved, but user experience may deteriorate due to excessive cooling in hand-holding positions
Solution Approach 1:
Different partition areas of the back cover are assigned different thermal characteristics through selective placement and control of radiating sub-fins. Areas that require cooling (near heat-generating components) have radiating sub-fins with larger contact areas, while hand-holding positions have reduced or no radiating sub-fin contact. This local differentiation allows effective temperature control without creating cold spots in user contact areas.
Solution Approach 2:
The back cover is divided into multiple partition areas, each with independently controllable radiating sub-fins. This segmentation allows the system to apply different heat dissipation strategies to different zones - aggressive cooling where needed and minimal cooling where user comfort is prioritized, thus resolving the contradiction between temperature control and user experience.
