Tremolo Stop Stabilizer Using Threaded Contact Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintaining the initial position of a tremolo in stringed musical instruments is challenging due to string stretch over time, which alters the harmonic tuning and pitch, especially when strings break, causing the tremolo to tilt and affect the pitch of remaining strings.
Innovation Solution
A threaded contact pin element and a magnetic stabilizer apparatus are integrated into the tremolo system to provide adjustable tension, allowing for a 'hard' or 'soft' stop mechanism to maintain the initial position by varying the force of tension, using either a compression spring or magnetic elements to counteract string tension changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a hard stop mechanism is used to prevent tremolo rotation, then the tremolo position stability is improved, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The patent combines the stop mechanism and adjustment mechanism into a single integrated assembly. The threaded contact pin element is directly integrated into the tremolo block, eliminating the need for separate stop and adjustment components. This merging reduces device complexity while maintaining the ability to provide a hard stop and adjust the contact point position.
Solution Approach 2:
The contact pin element serves multiple functions: it acts as a hard stop to prevent over-rotation, provides an adjustable reference point for tremolo positioning, and can be repositioned along the threaded engagement to accommodate different string configurations. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity.
2Stability of the object's composition
If a soft stop mechanism with resilient element is used, then the tremolo position stability is improved, but the device complexity increases due to additional components
Solution Approach 1:
The patent integrates the resilient element directly into the contact pin assembly, combining the stop function and the spring loading function into a single integrated component. The resilient element is positioned within the tremolo block and directly engages with the contact pin, eliminating the need for separate spring housings and mounting mechanisms.
Solution Approach 2:
The resilient element provides a dynamic, adjustable soft stop that can adapt to different playing conditions. The contact pin can be positioned at different locations along the threaded engagement to vary the force and position of the soft stop, allowing optimization for different string tensions and playing styles without requiring multiple fixed-stop mechanisms.
3Stability of the object's composition
If the contact pin is positioned closer to the nut, then the tremolo stability is improved, but the available tuning range decreases
Solution Approach 1:
The threaded engagement allows the contact pin to be dynamically repositioned along its axis. This enables the user to adjust the contact point position to optimize for either stability (closer to nut) or tuning range (farther from nut), or to find an intermediate position that balances both requirements based on the specific string configuration and playing style.
Solution Approach 2:
By changing the position parameter of the contact pin along the threaded engagement, the system can optimize different performance parameters. Moving the contact pin closer to the nut increases stability but reduces tuning range, while moving it farther increases tuning range but may reduce stability. The threaded design enables continuous adjustment of this critical parameter.
4Adaptability or versatility
If multiple adjustment mechanisms are provided, then the adaptability is improved, but the ease of operation decreases due to multiple adjustment steps
Solution Approach 1:
The patent merges the stop position adjustment and the contact pin positioning into a single threaded adjustment mechanism. By rotating the contact pin assembly, the user simultaneously adjusts both the position of the stop and the tension applied by the resilient element, eliminating the need for separate adjustment steps for each parameter.
Solution Approach 2:
The single threaded adjustment mechanism serves multiple functions: it positions the contact pin, applies tension to the resilient element, and sets the stop position. This multi-functional adjustment mechanism reduces the number of adjustment steps required while maintaining the ability to optimize multiple parameters for different playing conditions.

Function Achieved in This Case
The solution effectively stabilizes the tremolo at the initial position, preventing pitch changes and maintaining harmonic tuning, even when strings are broken, by adjusting the tension to compensate for string stretch and changes in string tension, allowing for continued play without pitch shifts.

AI summary
TREMOLO STOP is a contact pin based improvement integrated into the tremolo and/or its related parts, to adjustably make initial contact at initial position or at the zero point either in a fixed “hard stop” position that can be further adjusted to disengage from the body. The STABILIZER TUNER dynamic “soft stop” contact pin arrangement comprises a resilient element to provide a second variable force tension at the zero point of the tremolo. The contact pin is adjustable relative to the body. An adjustable stabilizer housing varies the second variable force of tension.
