Sliding Hinge Assembly for Gap-Free Curved Display Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in creating a curved screen by connecting multiple flat display modules without generating gaps between them, and in varying the curvature of the screen by adjusting the angle between modules.
Innovation Solution
A hinge assembly that includes rotatable brackets with moving blocks and a spacing adjustment mechanism, allowing for sliding movement of the display modules to adjust their spacing and angle, enabling the formation of both concave and convex shapes without gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If display modules are connected with fixed spacing, then the structure is simple, but gaps are generated when angle is changed
Solution Approach 1:
The hinge assembly incorporates a moving block that can dynamically adjust its position along the bracket through sliding movement. This dynamic mechanism allows the spacing between display modules to change automatically as the angle between modules is adjusted, eliminating gaps while maintaining structural integrity. The moving block transitions from a static to a dynamic component, enabling real-time adaptation to angular changes.
2Shape
If moving block is added to adjust spacing, then gaps are eliminated, but device complexity increases
Solution Approach 1:
The hinge assembly merges multiple functions into a single integrated structure. The bracket, moving block, and spacing adjustment mechanism are combined into one cohesive assembly that simultaneously provides angular adjustment and spacing control. This merging reduces the need for separate components and simplifies the overall installation process, offsetting the added complexity with functional integration.
Solution Approach 2:
The hinge assembly serves multiple functions: it enables angular adjustment between display modules, controls spacing to eliminate gaps, and provides structural support. The moving block acts as a multi-functional element that can slide to adjust spacing while also serving as a mounting point for the display module. This universality reduces the need for additional specialized components.
3Adaptability or versatility
If brackets are rotatable for angle adjustment, then screen curvature is achievable, but manufacturing precision requirements increase
Solution Approach 1:
The moving block is designed to self-adjust its position along the bracket as the angle between display modules changes. The sliding mechanism automatically compensates for spacing variations without requiring external intervention or complex control systems. This self-service feature reduces the burden on manufacturing precision by allowing the mechanism to adapt to minor variations through its own operation.
