Pivoting Hinge With Elastic Pressing Part For Stable Display Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing apparatuses, such as digital photo frames, have complex and unstable pivoting hinge configurations that complicate assembly and result in inconsistent friction during pivoting, leading to unstable operation.
Innovation Solution
A pivoting hinge design featuring a hinge shaft on the stand, a pivoting bracket with an elastic pressing part, and a pivoting angle limiting unit, which allows for stable and controlled pivoting of the display panel by generating a uniform friction force and limiting the pivoting angle, while being easy to assemble and cost-effective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional pivoting hinge configuration is used, then the display panel can pivot, but the assembly process becomes complex and the pivoting operation becomes unstable due to non-uniform friction force
Solution Approach 1:
The hinge is divided into separate functional components: a hinge shaft with shaft accommodator for rotation, a pivoting bracket for mounting, and an elastic pressing part for friction control. This segmentation allows each component to be optimized independently, simplifying the overall assembly process while ensuring stable pivoting operation through uniform friction force distribution.
Solution Approach 2:
The elastic pressing part acts as an intermediary element between the hinge shaft and the pivoting bracket. It provides controlled friction force to stabilize the pivoting operation without requiring complex coupling mechanisms. The elastic material mediates the interaction between moving parts, ensuring uniform friction throughout the pivoting range.
2Reliability
If a complex coupling configuration is used to achieve stable pivoting, then friction force can be maintained, but the assembly process becomes difficult and time-consuming
Solution Approach 1:
The elastic pressing part is designed to automatically generate the required friction force through its elastic deformation when compressed between the hinge shaft and pivoting bracket. This self-service mechanism eliminates the need for complex adjustment mechanisms or pre-set friction coefficients, making the assembly process simple and reliable while ensuring consistent pivoting stability.
Solution Approach 2:
The friction force is controlled by changing the compression parameter of the elastic pressing part. By adjusting the compression distance or elastic material properties, the friction force can be optimized for stable pivoting. This parameter-based control is much simpler to manufacture and assemble than mechanical friction control mechanisms.
3Measurement precision
If multiple components are used to control pivoting angle, then precise angle control is achieved, but the hinge structure becomes more complex
Solution Approach 1:
The hinge shaft with shaft accommodator serves multiple functions: it provides the rotation axis, guides the pivoting motion, and works with the elastic pressing part to control friction. The pivoting bracket simultaneously mounts the display panel and interfaces with the hinge shaft. This multi-functionality reduces the number of separate components needed for angle control, simplifying the overall hinge structure while maintaining precise control.
