Hinge Device Sliding Latch for Wide Tilting Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses with hinge devices are limited in their ability to tilt at various angles, typically allowing only about 20 degrees of rotation, which restricts user convenience and flexibility in adjusting the display's position.
Innovation Solution
A hinge device using a leaf spring mechanism with a guide member, latch, and pressure member that allows the display to tilt at various angles by sliding along a rail, and is secured when an external force is removed, enabling a wider range of tilting angles and maintaining stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional hinge device is used to connect the display to the stand, then the display can be tilted by rotating about a hinge axis, but the tilting angle is limited to about 20 degrees which restricts user convenience and flexibility
Solution Approach 1:
The hinge device transitions from a fixed rotation mechanism to a dynamic sliding mechanism. The latch member slides along the guide member's rail to dynamically adjust the display's tilted position, enabling continuous angle adjustment rather than fixed rotation points, thereby expanding the tilting angle range while maintaining ease of operation
Solution Approach 2:
The hinge device is divided into functional segments: guide member with rail, latch member, elastic member, and pressure member. This segmentation allows independent optimization of each component - the rail provides guidance, the elastic member provides restoring force, and the pressure member applies external force, collectively achieving wide-angle tilting with user convenience
2Adaptability or versatility
If the display is allowed to tilt freely to various angles, then user convenience is improved, but the display may move or become unstable when external force is removed
Solution Approach 1:
The elastic member provides automatic feedback control - when the display is tilted to any angle, the elastic member generates a restoring force that pushes the latch member back toward the neutral position. This feedback mechanism ensures the display automatically returns to a stable position when external force is removed, maintaining stability while allowing wide tilting range during use
Solution Approach 2:
The hinge device uses the elastic member to automatically counterbalance the display's weight and provide restoring force without external intervention. The system serves itself by using the tilt motion to compress the elastic member, which then automatically pushes back to maintain stability, eliminating the need for external support mechanisms
3Adaptability or versatility
If a sliding mechanism with guide member and latch is used to enable various tilting angles, then flexibility is improved, but the device complexity increases compared to traditional hinge mechanisms
Solution Approach 1:
The guide member uses a thin rail structure instead of a bulky traditional hinge mechanism. This rail-based guidance system provides the necessary directional constraint while occupying minimal space, reducing overall device complexity while maintaining tilting flexibility
Solution Approach 2:
The elastic member acts as an intermediary between the latch member and the display, converting the complex interaction of friction, normal forces, and gravitational components into a simple spring force relationship. This intermediary element simplifies the force analysis and reduces the need for complex control mechanisms

Implementation Method 1
a fixing member fixing the display such that the display is not moved when an external force applied to the display is removed
Implementation Method 2
The pressure member may include an elastic member mounted thereon, and a direction of an elastic force of the elastic member may be opposite to a direction of an elastic force of the leaf spring
