Torque Suppressor for Guitar Neck Dive Neutralization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Musical instruments, especially guitar-like instruments, experience neck dive and neck yaw due to uncomfortable weight distribution when held with a shoulder strap, leading to muscle strain and interference with playing techniques.
Innovation Solution
A torque suppressor providing a rigid, adjustable three-point support system that allows the shoulder strap to attach to the instrument at various locations, including the headstock and body, neutralizing neck dive and yaw while allowing for 'over-the-board' playing without obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a shoulder strap is used to hold the instrument, then the instrument can be carried conveniently, but the weight distribution becomes uncomfortable causing neck dive and muscle strain
Solution Approach 1:
The invention divides the single shoulder strap support system into a three-point support system with a shoulder strap attached to the body, a neck strap attached to the headstock, and a rigid extension connecting them. This segmentation allows independent adjustment of each strap to achieve proper weight distribution and eliminate neck dive.
Solution Approach 2:
The rigid extension acts as an intermediary element that connects the shoulder strap and neck strap, transferring and distributing the instrument's weight between the two attachment points. This mediator enables the three-point support system to function as a unified structure that balances the instrument's center of gravity.
2Ease of operation
If strap buttons are used to attach the shoulder strap, then the strap can be easily attached, but the strap may slip off due to friction variations and design differences
Solution Approach 1:
The invention replaces static friction-based strap button connections with dynamic locking mechanisms including strap locks and a rigid extension with attachment points designed to prevent slippage. These mechanisms actively maintain connection stability regardless of friction variations or design differences.
3Device complexity
If the shoulder strap attaches at fixed points on the instrument body, then the attachment is simple, but the player cannot adjust the instrument position for comfort or technique
Solution Approach 1:
The rigid extension incorporates adjustable components including a telescoping mechanism with multiple length positions and rotatable joints that allow the extension to adapt to different instrument geometries and player preferences. This enables dynamic adjustment of the three-point support configuration while maintaining structural integrity.
Solution Approach 2:
The rigid extension serves multiple functions: it connects the shoulder strap and neck strap, provides structural support, enables position adjustment, and adapts to different instrument types. This multi-functionality replaces the need for multiple separate adjustment mechanisms.
4Object-affected harmful factors
If a rigid extension is added to create three-point support, then neck dive is neutralized, but the device complexity increases
Solution Approach 1:
The invention combines the shoulder strap, neck strap, and rigid extension into an integrated three-point support system that functions as a unified structure. This merging eliminates the need for separate adjustment mechanisms and reduces overall system complexity while achieving neck dive neutralization.
