Rotating Mechanism With Integrated Positioning for Thin Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotating mechanisms are thick in the axial direction due to multiple stacked plate members, making them unsuitable for small-sized electronic devices, such as portable devices, as they require additional positioning pieces and coaxial locking structures that increase thickness.
Innovation Solution
A rotating mechanism design that integrates positioning structures on the first mount and first engagement component, eliminating the need for additional positioning pieces and using non-coaxial fasteners and shaft parts to reduce axial thickness, allowing for a more compact configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple plate members (positioning piece, limiting piece, mounting bracket) are stacked in the axial direction and fixed by a coaxial locking member, then the rotating mechanism achieves stable connection and positioning between two electronic modules, but the overall thickness of the rotating mechanism in the axial direction increases
Solution Approach 1:
The patent combines multiple separate plate members (positioning piece, limiting piece, mounting bracket) into an integrated structure where the positioning assembly is formed as part of the rotating mechanism body. This merging eliminates the need for separate stacked components while maintaining positioning and limiting functions, thereby reducing axial thickness without compromising connection stability
Solution Approach 2:
The positioning assembly serves multiple functions simultaneously: it provides positioning, limiting, and mounting functions that were previously distributed across separate components. By making the positioning assembly multi-functional, the patent eliminates the need for separate positioning pieces and limiting pieces, reducing the number of stacked plate members and thus reducing axial thickness while maintaining reliable connection
2Reliability
If multiple plate members and coaxial locking members are used, then the rotating mechanism achieves proper positioning and locking, but the device complexity increases with more components
Solution Approach 1:
The patent merges the positioning piece, limiting piece, and mounting bracket into an integrated positioning assembly that is formed as part of the rotating mechanism body. This reduces the number of separate components from multiple stacked plate members plus locking members to a single integrated structure, thereby reducing device complexity while maintaining positioning accuracy through the integrated design
3Reliability
If conventional rotating mechanism structure is used, then the mechanism achieves stable rotation between electronic modules, but it cannot be suitably applied to small-sized electronic products
Solution Approach 1:
By merging multiple plate members into an integrated positioning assembly, the patent significantly reduces the overall volume of the rotating mechanism. This integration eliminates the axial thickness accumulated from stacking multiple components, making the mechanism compact enough for small-sized electronic products while maintaining rotation stability through the integrated structural design
Solution Approach 2:
The patent repositions the positioning assembly from a separate stacked component to an integrated part of the rotating mechanism body, effectively changing the dimensional arrangement. This integration allows the mechanism to achieve stable rotation with reduced volume by eliminating the axial stacking dimension, making it suitable for compact electronic products

AI summary
A rotating mechanism includes a first mount having a shaft hole, a second mount having a mounting part and a shaft part, a first engagement component, and a positioning assembly having a first positioning structure and a second positioning structure. The shaft part passes through the shaft hole so that the second mount is rotatable relative to the first mount. The first engagement component is fixed to the second mount and located on one side of the first mount away from the mounting part of the second mount, so that the first engagement component rotates relative to the first mount along with the second mount. The first positioning structure disposed on the first mount and the second positioning structure disposed on the first engagement component are matching recess and protrusion that are engaged with each other so as to position the first mount and the second mount.
