Support Frame Joint with Friction Ring for Quick Angle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing microphone support frame is inconvenient to use due to the need to loosen and tighten threaded bolts one by one to adjust angles, making it difficult to adjust and position the microphone or other items effectively.
Innovation Solution
A joint device is introduced with a rotating seat unit and rotary shaft unit, featuring a tightening ring and one-way bearing, which allows for easy angle adjustment and positioning by utilizing frictional engagement and a tapered section in the tightening hole to facilitate smooth rotation and secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If threaded bolts are used to adjust angles between support arms, then the angles can be adjusted, but the adjustment process requires loosening and tightening bolts one by one which is inconvenient and time-consuming
Solution Approach 1:
The joint device is divided into distinct functional components: a rotating seat unit for angle adjustment, a rotary shaft unit for connection, and a quick-release mechanism with C-shaped body and positioning protrusions. This segmentation allows each component to perform its specific function independently, enabling quick angle adjustment without manipulating multiple fasteners.
Solution Approach 2:
The positioning protrusions are pre-formed on the rotating seat unit and the C-shaped body is pre-configured with corresponding receiving features. This preliminary preparation of engagement features eliminates the need for complex fastening operations during adjustment, allowing users to simply rotate and engage the components for quick positioning.
2Reliability
If multiple threaded bolts are used to fix angles, then the angles can be secured, but the complexity of the device increases due to multiple fastening components
Solution Approach 1:
Multiple fastening functions are merged into a single integrated joint device. The rotating seat unit combines angle adjustment, positioning, and securing functions in one component assembly, eliminating the need for separate threaded bolts and simplifying the overall structure while maintaining reliable angle fixation.
Solution Approach 2:
The joint device features self-positioning through the interaction of positioning protrusions and the C-shaped body with gap. The design automatically aligns and secures the components in the correct position through geometric constraints, eliminating the need for complex fastening procedures and reducing device complexity.
3Adaptability or versatility
If threaded bolts are loosened for adjustment, then angle changes are possible, but the frequent loosening and tightening reduces operational convenience
Solution Approach 1:
The joint device transitions from a static fastened state to a dynamic adjustable state through simple rotation of the rotating seat unit. The positioning protrusions and C-shaped body design allow the structure to dynamically adapt to different angles while maintaining secure engagement, eliminating the need to loosen and tighten fasteners for adjustment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The joint device simplifies the adjustment and positioning process, making it easier and more convenient to use, as the frictional engagement ensures secure placement of the rotating components at desired angles without the need for frequent tightening and loosening of bolts.
Implementation Method 1
The tightening ring has an inner annular surface frictionally engaged with the rotary shaft
Implementation Method 2
The tightening hole has a tapered section with large and small diameter ends. The small diameter end has a diameter smaller than that of the large diameter end.

AI summary
A joint device includes a rotating seat unit and a rotary shaft unit. The rotary shaft unit includes a fixed block defining a tightening hole, a rotary shaft fixed to the rotating seat unit and inserted into the tightening hole, and a tightening ring that is press-fitted into the tightening hole, that is frictionally engaged with the rotary shaft and that has large and small diameter ends. The rotary shaft is rotatable with the rotating seat unit relative to the fixed block. The tightening ring has a C-shaped body with a gap between two ends thereof. The gap of the tightening ring gradually reduces when it is gradually inserted from the large to the small diameter end of the tightening hole.
