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 the adjustment process cumbersome.
Innovation Solution
A joint device comprising a base seat, a rotating seat, and a shaft assembly with a one-way bearing and a tightening member, allowing for easy angle adjustment and positioning through frictional engagement, enabling simultaneous rotation of components to achieve desired angles without the need for sequential bolt tightening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If threaded bolts are used to fix angles, then the support frame can be adjusted to desired angles, but the adjustment process becomes cumbersome requiring sequential loosening and tightening of multiple bolts
Solution Approach 1:
The patent combines multiple adjustment functions into a single integrated joint device. The rotating seat and base seat with one-way bearing allow simultaneous adjustment of multiple angles through a single rotational motion, eliminating the need to sequentially adjust multiple threaded bolts. The frictional engagement between the tightening member and one-way bearing provides unified control over the adjustment process.
Solution Approach 2:
The one-way bearing acts as an intermediary mechanism between the rotating seat and base seat. It allows rotational motion to be transmitted in one direction while preventing reverse motion, enabling the adjustment mechanism to set angles through frictional engagement without requiring sequential bolt tightening. This intermediary component simplifies the operation by mediating the force transmission between user input and the final positioned configuration.
2Manufacturing precision
If multiple threaded bolts are used for angle adjustment, then precise angle control is achieved, but the device complexity increases
Solution Approach 1:
The patent merges multiple fastening functions into a single integrated joint device comprising a rotating seat, base seat, and one-way bearing assembly. This consolidation reduces the number of separate components while maintaining precise angle positioning capability through the frictional engagement mechanism between the tightening member and one-way bearing.
Solution Approach 2:
The one-way bearing provides self-locking functionality that maintains precise angle positioning without requiring multiple threaded bolts. Once the desired angle is achieved through rotational motion, the one-way bearing automatically prevents reverse motion, providing self-service positioning and locking functions that reduce overall device complexity.

AI summary
A joint device includes a base seat having a mounting hole with a tapered portion, and a rotating seat rotatably connected to the base seat. The tapered portion has large and small diameter ends. A shaft assembly includes a rotating shaft fixed to the rotating seat and inserted into the mounting hole, a one-way bearing sleeved on and frictionally engaged with the rotating shaft, and a tightening member press-fitted between an inner surface of the base seat and the one-way bearing. The tightening member has a C-shaped body with a gap that gradually reduces as the tightening member gradually moves from the large to the small diameter ends of the tapered portion.
