Hinge Module Stabilizes Display Screen During Touch Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computers experience visual discomfort and operational difficulty due to shaking of the display screen when pressed for touch input, as the pressing force causes the screen to vibrate.
Innovation Solution
A hinge module with a first pivot component, a second pivot component, and a sliding component, where the first pivot component rotates relative to the second pivot component to drive a positioning portion along a moving path, forming structural interference to stabilize the display when opened and allowing smooth closure by moving the positioning structure away from the path when closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display screen is made movable for touch input, then user interaction capability is improved, but screen stability deteriorates causing shaking and visual discomfort
Solution Approach 1:
The hinge module employs a dynamic positioning mechanism where the sliding component can transition between a first position (providing stability) and a second position (allowing movement). The elastic component enables the system to adapt its rigidity dynamically - rigid during normal operation for stability, and flexible during closure for ease of operation, thus resolving the contradiction between stability and operational ease
2Ease of operation
If the hinge structure is simplified for easy closure, then ease of operation is improved, but positioning accuracy deteriorates causing inability to stabilize during touch input
Solution Approach 1:
The hinge module is segmented into distinct functional components: a positioning component with positioning structure for accuracy, a sliding component for movement control, and an elastic component for flexibility. This segmentation allows each component to specialize - the positioning structure ensures precision when needed, while the sliding mechanism enables easy closure, resolving the contradiction between positioning accuracy and closure ease
3Stability of the object's composition
If the positioning structure is always engaged for stability, then display stability is improved, but closure operation deteriorates due to interference
Solution Approach 1:
The positioning structure's engagement state is dynamically controlled through the sliding component's position. During normal operation, the sliding component is at the first position with the positioning structure engaged to provide stability. During closure, the sliding component moves to the second position disengaging the positioning structure to allow smooth operation, thus resolving the contradiction between stability and closure ease

AI summary
An electronic device includes a first body, a second body and a hinge module. The hinge module includes a first pivot component, a second pivot component and a sliding component. The first pivot component fixed on the first body has a positioning portion. The second pivot component is fixed on the second body. The first pivot component is pivoted to the second pivot component. The sliding component slidably disposed at the second pivot component has a positioning structure. When the positioning structure is on a moving path of the positioning portion and the first pivot component rotates and drives the positioning portion to arrive at the positioning structure, the positioning structure interferes with the positioning portion to position the first pivot component. When the first pivot component rotates reversely, the positioning portion pushes the sliding component and the positioning structure moves away from the moving path.
