Layered Sheet Hinge with Soft Resin Pivot Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinges often experience smooth pivoting issues or noise during operation when coupling an opening frame and a shield, leading to inefficient motion.
Innovation Solution
A hinge is designed with a sheet body composed of layered sheet members, featuring a pivot shaft between them, allowing one end to pivot relative to the other, with an axial member and bulge configuration for smooth operation and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional hinges with flat vanes and pivot shaft are used, then the structure is simple, but pivoting motion becomes rough and noise occurs during operation
Solution Approach 1:
The sheet body is divided into multiple sheet members (first sheet member and second sheet member) that are layered and coupled together. This segmentation allows each sheet member to contribute to the pivoting motion independently, improving smoothness and reducing noise through the distributed interaction of multiple surfaces during rotation.
2Reliability
If conventional hinges are used, then manufacturing is simple, but reliability of pivoting motion deteriorates due to rough motion and noise
Solution Approach 1:
Multiple sheet members are coupled together to form an integrated sheet body structure. This merging of multiple components into a unified assembly improves the reliability of pivoting motion while maintaining reasonable structural complexity through the systematic arrangement of layered sheets.
3Duration of action of stationary object
If conventional hinges are used, then installation is simple, but durability deteriorates due to rough pivoting and noise
Solution Approach 1:
The sheet body is segmented into multiple sheet members that can be independently manufactured and then assembled. This segmentation allows for optimized manufacturing of individual components while improving overall durability through the collective performance of the layered structure during prolonged pivoting operations.

AI summary
A hinge for connecting a first pivoting body to a second pivoting body in a relatively pivotable manner includes a sheet body configured to attach a first end of the sheet body to the first pivoting body, and to attach a second end of the sheet body to the second pivoting body. The sheet body includes a plurality of layered sheet members, and a pivot shaft between layered sheet members of the plurality of layered sheet members to allow the first end and the second end of the sheet body to pivot relative to each other. The pivot shaft includes a soft resin part between the layered sheet members.
