Clamping Rod Frame With Replaceable Locking Joints for Wear Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing musical instrument clamps suffer from wear and tear leading to insufficient clamping force due to friction, and require replacement of worn-out parts, while rotary joints increase the likelihood of loosening with increased weight.
Innovation Solution
A clamping rod frame with a design featuring pivotally connected clamping blocks, vertical and horizontal rotating joints, and locking members that allow for adjustable clamping and tilt angle adjustment, with replaceable locking components to extend service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screw locking member presses an outer curved surface of a movable member to enable rapid assembly and disassembly, then the ease of operation is improved, but the friction causes wear and deformation of the outer curved surface, reducing the service life and reliability
Solution Approach 1:
A T-shaped groove component is introduced as an intermediary between the screw locking member and the movable member. The groove component absorbs the friction and wear from the pressing action, protecting the movable member's outer curved surface. The groove component can be replaced when worn, while the movable member remains intact, thus resolving the contradiction between ease of operation and reliability.
2Adaptability or versatility
If rotary joints are used to adjust the relative inclination angle of vertical rods, then the adaptability is improved, but the increase in weight increases the possibility of loosening of the clamp
Solution Approach 1:
The groove component is pre-installed on the movable member before the screw locking member is engaged. This preliminary positioning ensures that when the screw presses down during operation, the groove component is already in place to distribute the load and prevent direct friction on the movable member's curved surface, thereby preventing loosening while maintaining adaptability.
3Reliability
If the outer curved surface of the movable member is worn out, then the clamp cannot provide sufficient clamping force, but replacing the movable member as a whole set is costly and reduces productivity
Solution Approach 1:
The clamping mechanism is segmented into replaceable components: the groove component can be replaced independently when worn, while the movable member and other components remain in use. This segmentation allows for quick replacement of only the worn groove component rather than the entire movable member assembly, thereby maintaining clamping force while improving productivity by reducing replacement time and cost.
Applied Scientific Principles

Function Achieved in This Case
Provides flexible and durable clamping with adjustable tilt angles, extending the service life of the clamping mechanism and enhancing stability.
Implementation Method 1
In the process of pressing the outer curved surface of the movable member by the screw locking member, the screw locking member moves relative to the outer curved surface under friction
Implementation Method 2
the first clamping block and the second clamping block pivotally connected together through a pivot so that the first clamping block and the second clamping block can be rotated relative to each other
Implementation Method 3
the second screw locking head and the second bolt press the first vertical joint and the second vertical joint to clamp and fix each other
Implementation Method 4
the third screw locking head and the third bolt press the first horizontal joint and the second horizontal joint to clamp and fix each other

AI summary
A clamping rod frame includes a first clamping block (10), a second clamping block (20), a first locking member (30), a vertical rotating joint (40), a second locking member (50), a horizontal rotating joint (60), a third locking member (70), and a mounting rod (80). The first and second clamping blocks (10, 20) are pressed by the first locking member (30) to clamp a vertical rod (L). The vertical rotating joint (40) includes first and second vertical joints (41, 42) relatively rotating and pressed and fixed by the second locking member (50), and the first vertical joint (41) is connected to the second clamping block (20). The horizontal rotating joint (60) includes first and second horizontal joints (61, 62) relatively rotating and pressed and fixed by the third locking member (70), and the first horizontal joint (61) is connected to the second vertical joint (42). The mounting rod (80) is inserted into a mounting ring (73) of the third locking member (70) and pressed and fixed by a groove (622) of the second horizontal joint (62).
