Musical Instrument Nut Clamp Jaw for Rotation-Resistant Stand Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing quick-release clamp for musical instruments can detach accidentally from the stand due to the clamp jaw rotating, despite being engaged, leading to instability and potential loss of the instrument.
Innovation Solution
A nut for musical instruments featuring a clamp jaw with an elastic member that directly clamps to the stand in the closed position, an operating element with a pressing portion to hinder opening, and a housing to accommodate these components, ensuring secure attachment by preventing rotation and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the clamp jaw is held in the closed position by the operating element only, then the operating mechanism is simple, but the clamp jaw can rotate and detach accidentally from the stand
Solution Approach 1:
The elastic member is pre-loaded to continuously press the clamp jaw against the stand before any detachment force is applied. This preliminary clamping action ensures that the clamp jaw maintains firm contact with the stand, preventing rotation and accidental detachment even when the operating element only holds the jaw in position without active pressing.
Solution Approach 2:
The elastic member acts as an intermediary between the clamp jaw and the stand, providing a continuous pressing force that mediates the connection. This intermediary force ensures reliable attachment by maintaining constant pressure on the clamp jaw against the stand, preventing rotation and detachment while keeping the operating mechanism relatively simple.
2Reliability
If the elastic member presses the clamp jaw directly on the stand, then the attachment is secure and prevents rotation, but the structure becomes more complex
Solution Approach 1:
The elastic member is integrated with the operating element, merging two functions into a single component structure. The operating element serves both as the manual actuator for opening/closing the clamp jaw and as the mounting structure for the elastic member. This merging reduces overall structural complexity while maintaining the pressing function that prevents rotation and detachment.
Solution Approach 2:
The elastic member is nested within or integrated into the housing and operating element structure. This nesting arrangement allows the elastic member to be housed compactly within the existing structure without adding significant external complexity, while still providing the necessary pressing force to secure the clamp jaw to the stand and prevent rotation.
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 nut provides stable, secure attachment to the stand by increasing frictional force and preventing accidental detachment, even under impact, while allowing easy installation and removal without rotating, and is compact due to the torsion spring's integration with the rotation shaft.
Implementation Method 1
an elastic member configured to, in a state of the clamp jaw being in the closed position, clamp the clamp jaw to the stand by exerting a force directly on the clamp jaw
Implementation Method 2
The nut provides stable, secure attachment to the stand by increasing frictional force

AI summary
A nut for a musical instrument includes: a clamp jaw having an opening through which a stand is passable, the clamp jaw being configured to, in a state of the stand being disposed in the opening, change a size of the opening by changing a position of the clamp jaw between an open position and a closed position; an elastic member configured to, in a state of the clamp jaw being in the closed position, clamp the clamp jaw to the stand by exerting a force directly on the clamp jaw; an operating element having a pressing portion and a front end portion; and a housing accommodating the clamp jaw, the elastic member, and the operating element.
