Clamping Rod Frame With Rotary Joints for Wear-Resistant Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing musical instrument clamps suffer from wear and tear leading to insufficient clamping force and short service life, and require replacement of worn parts, while rotary joints increase the likelihood of clamp loosening due to increased weight.
Innovation Solution
A clamping rod frame with a first and second clamping block, vertical and horizontal rotating joints, and locking members that allow for adjustable tilt angles and secure clamping through pivotally connected surfaces and screw locking mechanisms, enabling easy replacement of damaged components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a screw locking member presses the outer curved surface of a movable member to enable rapid assembly and disassembly, then assembly speed is improved, but friction causes wear and deformation of the outer curved surface, reducing service life
Solution Approach 1:
A T-shaped groove is introduced as an intermediary structure between the screw locking member and the movable member. The groove guide portion guides the screw locking member, distributing the pressing force along the groove rather than concentrating it on a single point of the outer curved surface. This reduces localized wear and deformation while maintaining the rapid assembly capability
Solution Approach 2:
The design changes the contact interface from a point contact (screw pressing directly on outer curved surface) to a line contact along the T-shaped groove. This parameter change in contact geometry distributes the frictional wear over a longer path, extending the service life of the outer curved surface while preserving the quick-release function
2Adaptability or versatility
If rotary joints are added to adjust the relative inclination angle of vertical rods, then adaptability is improved, but the increased weight increases the possibility of clamp loosening
Solution Approach 1:
The rotary joints are designed with dynamic locking capability through the screw locking members that can engage with the T-shaped grooves. This allows the system to transition from a static fixed position to a dynamically adjustable position, maintaining reliability at each adjusted angle while preserving adaptability across multiple angles
Solution Approach 2:
The T-shaped groove structure serves as an intermediary that provides both guidance and locking functions. It allows the rotary joints to be adjusted to different angles while the screw locking members engage with the groove to prevent loosening, thus maintaining clamp stability despite the added weight of the rotary joints

Function Achieved in This Case
Provides a clamping rod frame with extended service life and adjustable tilt angles, ensuring secure clamping and easy maintenance by allowing replacement of worn parts, while maintaining stability and adjustability.
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 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 3
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, a second clamping block, a first locking member, a vertical rotating joint, a second locking member, a horizontal rotating joint, a third locking member, and a mounting rod. The first and second clamping blocks are pressed by the first locking member to clamp a vertical rod. The vertical rotating joint includes first and second vertical joints relatively rotating and pressed and fixed by the second locking member, and the first vertical joint is connected to the second clamping block. The horizontal rotating joint includes first and second horizontal joints relatively rotating and pressed and fixed by the third locking member, and the first horizontal joint is connected to the second vertical joint. The mounting rod is inserted into a mounting ring of the third locking member and pressed and fixed by a groove of the second horizontal joint.
