Hinge module and electronic device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinge modules in electronic devices, such as notebook and tablet computers, create a gap between the device's bodies when unfolded, affecting touch operation, gaming experiences, and image outputs due to the required spacing, and do not efficiently accommodate additional functional elements when folded.
Innovation Solution
A hinge module comprising a base, first and second shafts, brackets, and a linkage component that adjusts the spacing between the shafts to allow the device bodies to move closer together for improved performance when unfolded and further apart for accommodation of additional elements when folded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional hinge module is used to connect the first body and the second body, then the device can be folded and unfolded, but a gap of certain width exists between the first body and the second body when unfolded, affecting touch operation and image playing functions
Solution Approach 1:
The hinge module employs a dynamic linkage mechanism with movable connection points that allow the distance between the first shaft and second shaft to change. When unfolded, the linkage component enables the shafts to move closer together, dynamically reducing the gap width between the first body and second body to minimize interference with touch operations and image display.
2Ease of operation
If the first body and the second body are positioned close together when unfolded, then touch operation and image playing functions are improved, but the device cannot be properly folded without interference
Solution Approach 1:
The linkage component provides dynamic adaptability by allowing the distance between the first shaft and second shaft to change based on the folding state. When folded, the linkage mechanism enables the shafts to move apart, providing sufficient clearance for the bodies to fold without interference, thus maintaining both close positioning when unfolded and proper folding capability.
Solution Approach 2:
The hinge module changes the positional parameter (distance between shafts) based on the device state. The linkage component mechanism transforms the fixed distance into a variable parameter that can be adjusted between a smaller value when unfolded and a larger value when folded, resolving the contradiction between close positioning and folding capability.
3Ease of manufacture
If a fixed distance is maintained between the first shaft and the second shaft, then the structure is simple, but the gap between the first body and the second body cannot be reduced when unfolded
Solution Approach 1:
The linkage component introduces a controlled dynamic element that allows the distance between the first shaft and second shaft to vary. This dynamic adjustment mechanism reduces the gap when unfolded while maintaining reasonable structural simplicity through the use of standard linkage components that can be integrated into the existing hinge module architecture.

AI summary
A hinge module includes a base, a first shaft, a second shaft, a first bracket, a second bracket, and a linkage component. The base has a bottom plate and two guiding plates opposite to each other. The first shaft is movably and rotatably penetrates through the two guiding plates. The second shaft is movably and rotatably penetrates through the two guiding plates. The first bracket is disposed at a first end of the first shaft. The second bracket is disposed at a first end of the second shaft. The linkage component is disposed in the base and is connected to the first shaft and the second shaft. The first shaft and the second shaft linearly move along the two guiding plates through the linkage component to change a spacing distance between the first shaft and the second shaft and are configured to drive the first bracket and the second bracket to move away from each other or approach each other.
