Multi-Link Hinge Layout for Gapless Folding Display Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge mechanisms project above the connected structures, preventing seamless contact and causing interference during movement, making it difficult to achieve a gapless connection between bodies.
Innovation Solution
A hinge device with a first and second structure featuring guide grooves and link members, allowing the structures to be spaced apart or seamlessly contact each other, with specific link member lengths and orientations to avoid interference during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hinge mechanism is mounted between two bodies to enable rotation, then the bodies can move relative to each other, but the hinge mechanism projects above the bodies preventing seamless contact
Solution Approach 1:
The hinge mechanism is nested within recesses formed in the first and second bodies, with the guide grooves and link members contained within the structural boundaries of the bodies. This nesting allows the hinge mechanism to enable rotation while preventing projection above the bodies, thus achieving seamless contact between opposing surfaces.
Solution Approach 2:
The hinge mechanism utilizes the internal three-dimensional space within the bodies by forming recesses and positioning components in specific spatial relationships. The guide grooves are formed in diagonal directions and the link members are positioned at specific orientations to enable rotation while maintaining a sleek external profile.
2Ease of operation
If a hinge mechanism projects above the bodies to enable rotation, then the rotation function is achieved, but interference occurs in the moving path during movement
Solution Approach 1:
The hinge mechanism is divided into separate functional components: guide grooves for directional guidance, link members for motion transmission, and shafts for rotation. Each component is optimized to perform its specific function within the recess, allowing smooth rotation without interference in the moving path.
3Shape
If the hinge mechanism is designed to enable seamless contact, then the aesthetic appearance is improved, but the complexity of the structure increases
Solution Approach 1:
The recesses serve multiple functions: they contain the hinge mechanism components, provide structural support, enable seamless contact appearance, and guide the motion path. The guide grooves simultaneously provide geometric guidance and constrain the link members to specific movement paths, reducing the need for additional guiding components.

AI summary
A hinge device and a display apparatus including the same are disclosed. The hinge device comprises: a first structure having a first guide groove; a second structure having a second guide groove; a first shaft disposed between the first structure and the second structure; a first link member connecting the first shaft to a second shaft; a second link member connecting the first shaft to a third shaft moved in the first guide groove; a third link member connecting the first shaft to a fourth shaft in the second structure; and a fourth link member connecting the first shaft to a fifth shaft moved in the second guide groove, wherein a length of the second link member is greater than a length of the first link member, and a length of the fourth link member is greater than a length of the third link member. Accordingly, it is possible to seamlessly contact the first structure and the second structure.
