Rollable Display Heat Dissipation Member for Lateral Heat Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with rollable displays face challenges in securing a heat dissipation structure while maintaining portability and miniaturization, as high-performance components generate heat that can degrade adjacent components.
Innovation Solution
The electronic device incorporates a heat dissipation structure that transfers heat generated by components in a width direction using a heat dissipation member on a side wall member, which is connected to a support structure and a hinge module, allowing for efficient heat diffusion and transfer outside the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high-performance components are integrated into the electronic device, then device functionality and processing power are improved, but heat generation increases causing component degradation
Solution Approach 1:
The patent extracts the heat dissipation function from the main device body by introducing a separate heat dissipation member positioned outside the housing. This heat dissipation member includes a heat transfer portion that contacts the housing and a heat radiation portion that extends outward, effectively removing heat from the internal component environment to prevent degradation while maintaining high processing power
Solution Approach 2:
The patent introduces the heat dissipation member as an intermediary between the internal high-performance components and the external environment. The heat transfer portion acts as a thermal conduit, mediating heat flow from the housing to the heat radiation portion, thereby protecting internal components from direct heat exposure while enabling efficient heat dissipation
2Area of stationary object
If display size is increased for multimedia services, then user experience is improved, but device size increases reducing portability
Solution Approach 1:
The patent extends the heat dissipation structure in the width direction (lateral dimension) rather than increasing device thickness. The heat dissipation member includes a heat radiation portion that protrudes from the housing in the width direction, utilizing unused lateral space to provide heat dissipation functionality without increasing overall device footprint or weight, thereby maintaining portability while supporting large display requirements
