Sliding Hinge Structure for Heat-Venting Foldable Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic device hinges obstruct heat dissipation and limit display range due to the second housing covering heat dissipating holes and concealing the bottom of the first housing when opened.
Innovation Solution
A hinge design featuring a base frame, support frame, and transmitting mechanism with sliding plates and a rotating axle unit that allows the second housing to move away from the rear end of the base frame, maintaining heat dissipating holes open and enhancing display visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the second housing is opened to enhance display range, then the display visibility is improved, but the bottom of the second housing conceals the heat dissipating holes of the first housing, causing heat dissipation blockage
Solution Approach 1:
The hinge incorporates a transmitting mechanism with sliding plates that dynamically adjust the position of the support frame relative to the base frame. When the second housing is opened, the sliding plates enable the support frame to move away from the rear end of the base frame, preventing the bottom of the second housing from concealing the heat dissipating holes. This dynamic adjustment resolves the contradiction by making the heat dissipation status changeable rather than fixed, allowing both display visibility and heat dissipation to be optimized simultaneously.
2Illumination intensity
If the second housing is opened to improve display range, then the display visibility is enhanced, but the rear side of the first housing conceals the bottom of the second housing, limiting the display range
Solution Approach 1:
The hinge mechanism enables dynamic positioning of the second housing relative to the first housing. The transmitting mechanism with sliding plates allows the support frame to move away from the base frame when opened, creating additional space that prevents the rear side of the first housing from concealing the bottom of the second housing. This dynamic adjustment expands the effective display range while maintaining good visibility.
3Device complexity
If a conventional hinge structure is used to connect the first and second housings, then the device structure is simple, but the heat dissipating holes are blocked and the display range is limited
Solution Approach 1:
The hinge incorporates a transmitting mechanism with sliding plates and a rotating axle unit that enables dynamic adjustment of the support frame position. This dynamic structure allows the hinge to maintain a compact form when closed while expanding the effective space when opened, preventing heat dissipation blockage without requiring a fundamentally complex hinge design.
Solution Approach 2:
The transmitting mechanism features nested sliding plates where the first sliding plate and second sliding plate are arranged in an overlapping configuration. The sliding plates can be superimposed upon each other in the retracted state, allowing the mechanism to maintain a compact profile when the second housing is closed, similar to nested dolls.

AI summary
A hinge includes a base frame, a support frame and a transmitting mechanism. The base frame includes front and rear ends. The transmitting mechanism includes a first sliding plate, a second sliding plate and a transmitting assembly. The first and second sliding plates are connected with and slidable relative to the base frame in a front-rear direction. The transmitting assembly includes a rotating axle unit and a linkage unit. The rotating axle unit is movable with the support frame to cause sliding movements of the first and second sliding plates and a pivoting of the linkage unit relative to the base frame so as to shift the first and second sliding plates between retracted and projecting states.
