Adjustable Guitar Neck Pivot for String Height Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The neck of a guitar can become misaligned over time due to years of string tension, causing the strings to raise off the fingerboard and making the instrument unplayable, requiring a complex and professional neck reset process.
Innovation Solution
An apparatus and method that allows for adjusting the angle between the neck and body of a guitar without disassembly, using a pivot and adjustable fasteners to change the neck's angle relative to the body, allowing for easy and precise string height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional neck reset is performed to correct misalignment, then the neck angle can be corrected, but the process requires disassembly and professional expertise
Solution Approach 1:
The patent applies the dynamics principle by making the neck angle adjustable rather than fixed. The neck assembly can be rotated to different angles and locked in position, allowing the guitar to adapt to changing string tension and wear over time. This dynamic adjustment mechanism eliminates the need for complex disassembly and reassembly procedures while achieving precise neck angle correction.
Solution Approach 2:
The patent applies segmentation by dividing the neck into adjustable segments that can be independently positioned. The neck assembly includes a neck plate and neck piece that can be rotated relative to each other, allowing precise control of the neck angle without requiring complete disassembly of the guitar. This segmented approach simplifies the adjustment process while maintaining structural integrity.
2Duration of action of stationary object
If string tension is maintained over time, then the guitar remains playable, but the neck angle deteriorates due to wood strain
Solution Approach 1:
The dynamic adjustment mechanism allows the neck angle to be corrected periodically without compromising long-term playability. The adjustable neck assembly can be repositioned to compensate for wood strain accumulation, enabling the guitar to maintain optimal playing conditions over extended periods while accommodating natural material changes.
Solution Approach 2:
The patent applies preliminary action by incorporating an adjustable mechanism that can proactively correct neck angle issues before they become severe. The ability to adjust the neck angle allows owners to perform preventive maintenance, realigning the neck before string height becomes unplayably high, thereby extending the instrument's usable life.
3Ease of operation
If the neck is made adjustable to correct misalignment, then neck angle can be corrected easily, but the structural complexity of the neck assembly increases
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the neck assembly can be rotated to different angles and secured with a locking mechanism. This allows easy adjustment of the neck angle by simply rotating the neck piece to the desired position and engaging the lock, providing operational simplicity despite the added structural elements for adjustment and locking.
Solution Approach 2:
The patent uses an intermediary neck plate and locking mechanism that mediates between the fixed body and the adjustable neck piece. This intermediary structure enables easy angle adjustment while maintaining a relatively simple overall design, as the locking mechanism and rotation interface are contained within the neck assembly rather than requiring complex modifications to the entire guitar structure.
