Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotating mechanisms for screens, especially those used with All-in-One PCs, face structural weakness and reduced service life due to excessive weight, leading to damage and loss of rotating function.
Innovation Solution
A rotating mechanism with a supporting stand and base, featuring rotatable covers and cushions for enhanced friction, a blocking column and restraining mechanism, and an angle compensating member to ensure stable and extended rotation capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rotating mechanism is adapted for heavier All-in-One PC screens, then the rotating function can be maintained, but the positioning protrusion receives excessive force causing damage and loss of rotating function
Solution Approach 1:
The base is divided into a first cover and a second cover that can rotate relative to each other. The first cover includes positioning protrusions that engage with positioning holes in the second cover, separating the positioning function from the rotating function. This allows the second cover to rotate relative to the first cover without subjecting the positioning protrusions to excessive force, as the positioning structure remains stationary while rotation occurs between the two covers.
Solution Approach 2:
The first cover acts as an intermediary between the base and the rotating second cover. The positioning protrusions on the first cover engage with the second cover, mediating the connection between the fixed base and the rotating component. This intermediary structure distributes the mechanical stress and allows rotation without damaging the positioning protrusions.
2Reliability
If the positioning plate is fixed on the base to prevent rotation, then positioning is achieved, but the supporting stand must drive the inner plate to rotate which increases structural complexity
Solution Approach 1:
Instead of fixing the positioning plate to the base and having the supporting stand rotate the inner plate, the invention inverts the approach by making the second cover rotatable relative to the first cover. The positioning protrusions on the first cover remain stationary while the second cover rotates, reversing the traditional rotation mechanism and simplifying the overall structure.
Solution Approach 2:
The invention introduces dynamic rotation between the first cover and second cover, where the second cover can rotate relative to the fixed first cover. This dynamic design allows the positioning structure to remain stable while enabling rotation through the relative movement between the two covers, reducing the complexity of the supporting stand's rotation mechanism.
3Ease of operation
If the base is made rotatable to enable screen rotation, then rotating capability is improved, but the base needs additional structures like cushions and blocking portions which increases device complexity
Solution Approach 1:
The invention merges the positioning function and rotation function into a single integrated base structure. The first cover provides positioning through its protrusions, while the second cover provides rotation relative to the first cover. By combining these functions in one base assembly rather than requiring separate mechanisms, the overall device complexity is reduced despite the added rotatable components.
Solution Approach 2:
The base structure serves multiple functions: the first cover provides positioning through engagement with the second cover, the second cover enables rotation, and the cushion provides friction for stable operation. This multi-functional design consolidates several features into a single base assembly, improving ease of operation without proportionally increasing device complexity.

Function Achieved in This Case
The mechanism provides enhanced structural strength and extended service life by allowing 360-degree rotation without obstacles, addressing the issues of wear-out and short service life caused by overweight screens.
Implementation Method 1
at least one cushion is installed on a side of the second cover close to the supporting surface, and the at least one cushion provides a friction force
