Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional desktop adjustable hardware brackets lack reliable stop-at-any-position structures, leading to unstable angle support, complex locking mechanisms, and poor anti-slip performance, which affects user experience and safety.
Innovation Solution
A desktop adjustable hardware bracket with a stop-at-any-position rotating shaft mechanism using T-shaped shaft levers and friction sleeves, combined with anti-slip silicone pads and sheets, ensures stable angle adjustment and secure device placement without additional locking devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locking devices are added to enable stop-at-any-position function, then the bracket can stably stop at arbitrary angles, but the device complexity increases and operations become complicated
Solution Approach 1:
The rotating shaft mechanism automatically stops at any position through the interaction between the friction sleeve and the gear structure, without requiring external locking devices or manual operations. The system self-regulates the rotation and maintains position through its own structural characteristics
Solution Approach 2:
The mechanism uses dynamic friction control where the friction sleeve can slide along the gear teeth during rotation, allowing continuous angle adjustment, and automatically locks at any position through the meshing structure, providing both mobility and stability
2Reliability
If traditional locking devices are added to enable stop-at-any-position function, then the bracket can stably stop at arbitrary angles, but the ease of operation deteriorates
Solution Approach 1:
The system performs the locking function automatically through its own structure. When rotating the supporting plate, the friction sleeve naturally engages with the gear teeth, allowing free rotation and automatic stopping at any angle without requiring separate locking operations
Solution Approach 2:
The rotation adjustment function and the locking function are merged into a single integrated mechanism. The same rotating motion that adjusts the angle also automatically engages the locking feature, eliminating the need for separate locking operations
3Reliability
If anti-slip materials are added to improve anti-slip performance, then device sliding or falling is prevented, but the device complexity increases
Solution Approach 1:
Anti-slip silicone sheets are applied locally at specific contact surfaces where sliding prevention is needed, rather than modifying the entire structure. This targeted approach provides the necessary friction enhancement without adding complex structural elements
Solution Approach 2:
The patent combines metal structural components with silicone anti-slip materials to create a composite structure that leverages the strength and rigidity of metal while utilizing the high-friction properties of silicone for slip prevention

Implementation Method 1
a friction sleeve made of a polyformaldehyde material sleeves the insertion shaft body; and the friction sleeve is sleeved inside the second shaft sleeve
Implementation Method 2
a first meshing tooth is arranged on an outer side of a lever body of each T-shaped shaft lever; the first meshing tooth is in meshing connection with a second meshing tooth arranged inside each first shaft sleeve
Implementation Method 3
four corners of a bottom of the bottom plate are fixedly connected with a plurality of silicone pads; and a top of the bottom plate and an inner side of the first flange portion are fixedly connected with first anti-slip silicone sheets

AI summary
A desktop adjustable hardware bracket is provided, including a bottom plate. An upwards bent first flange portion is arranged at one end of the bottom plate, and a U-shaped slot is provided in another end of the bottom plate. First shaft sleeves formed by inwards curling a plate body are arranged on two sides of a notch of the U-shaped slot. An interior of the U-shaped slot and interiors of the first shaft sleeves are connected with a supporting plate through a stop-at-any-position rotating shaft mechanism mounted. A backwards bent second flange portion is arranged at one end of the supporting plate. By the arrangement of the stop-at-any-position rotating shaft mechanism, a first meshing tooth on an outer side of a T-shaped shaft lever is used to mesh with second meshing teeth inside the first shaft sleeves.
