Foldable Display Hinge With Lifting Support for Panel Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible panels in electronic devices, particularly those with inward folding designs, face damage risks due to being squeezed between device bodies during bending operations, as existing technologies lack effective protection mechanisms.
Innovation Solution
An electronic device design incorporating a hinge mechanism, driving mechanisms, and lifting mechanisms that allow the flexible panel's bending portion to ascend or descend, ensuring it is protected from damage by being moved into the device bodies during folding, utilizing a hinge mechanism with pivotally and slidably connected hinge members and driving mechanisms connected to lifting mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible panel is designed with inward folding configuration, then the device achieves compact folding capability, but the bending portion is squeezed and damaged by the two bodies during bending operation
Solution Approach 1:
The lifting mechanisms are activated before the bending portion comes into contact with the device bodies during folding. The control system detects the folding state and preemptively lifts the bending portion to the first position, preventing it from being squeezed between the first and second bodies before damage can occur.
Solution Approach 2:
The lifting mechanisms act as intermediary devices between the device bodies and the bending portion. These mechanisms provide a protective buffer by actively positioning the bending portion away from the compressive zone created by the closing device bodies, thus mediating the interaction and preventing direct damage.
2Reliability
If the bending portion is lifted away from the device bodies during folding, then protection from damage is achieved, but the device complexity increases due to additional lifting mechanisms
Solution Approach 1:
The lifting mechanisms are integrated with the existing hinge mechanism structure. The driving mechanisms that control the hinge movement are combined with the lifting function, allowing a single integrated system to perform both hinge rotation and bending portion elevation, thereby reducing overall structural complexity despite the added protective function.
Solution Approach 2:
The driving mechanisms serve dual functions: they control the rotation of the hinge members for folding operation and simultaneously drive the lifting mechanisms to protect the bending portion. This multi-functionality eliminates the need for separate dedicated lifting actuators, reducing the overall complexity of the system.

AI summary
An electronic device includes a first body, a second body, a hinge mechanism, two driving mechanisms, at least two lifting mechanisms, and a flexible panel. The first body is connected to the second body through the hinge mechanism. The two driving mechanisms are disposed in the first and second bodies, respectively, and the hinge mechanism is connected to the two driving mechanisms. The lifting mechanisms are respectively disposed in the first body and the second body, and each lifting mechanism is connected to the corresponding driving mechanism. The hinge mechanism is configured to drive the two driving mechanisms which respectively drive the two lifting mechanisms to ascend or descend. The flexible panel includes a first bonding portion secured to the first body, a second bonding portion secured to the second body, and a bending portion between the first and second bonding portions. The bending portion contacts the two lifting mechanisms.
