Existing flexible electronic devices face challenges in efficiently dissipating heat generated by components like circuit boards and batteries, which can affect performance and longevity.
Innovation Solution
A heat dissipation structure is implemented using heat dissipation members disposed on the upper and lower portions of a support plate, with a first heat dissipation member between the display panel and the support plate, and a second heat dissipation member filling the space portions, and a second heat dissipation member filling the space, and a third heat dissipation member between the display panel and the support plate, and a second heat dissipation member between the display assembly, and a third heat dissipation member between the heat generating elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation members are added to improve heat dissipation efficiency, then heat dissipation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple heat dissipation members (first, second, and third heat dissipation members) into a unified heat dissipation system that works synergistically. The first heat dissipation member contacts the display panel, the second fills space portions of the support plate, and the third contacts heat generating elements, creating an integrated thermal management solution that improves heat dissipation efficiency without proportionally increasing complexity
Solution Approach 2:
The support plate serves multiple functions: it provides structural support for the display assembly and simultaneously acts as a heat dissipation structure through its space portions that contain the second heat dissipation member. This multi-functionality allows the same component to address both structural and thermal management requirements, reducing overall device complexity
2Temperature
If heat dissipation members are disposed in limited internal space, then heat dissipation efficiency is improved, but available space for other components is reduced
Solution Approach 1:
The support plate is designed with space portions (porous structure) that accommodate the second heat dissipation member. These space portions are strategically located to enable heat dissipation while minimizing impact on overall device volume. The porous configuration allows thermal management functionality to be integrated within the existing structural framework rather than adding separate bulk components
Solution Approach 2:
The heat dissipation members are arranged in multiple dimensions and layers: the first heat dissipation member is positioned between the display panel and support plate, the second heat dissipation member fills vertical space portions within the support plate, and the third heat dissipation member is placed between heat generating elements and other components. This multi-dimensional arrangement maximizes heat dissipation surface area while efficiently utilizing the limited internal volume
