Rockable Bridge Assembly for Stringed Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stringed instrument bridges require cumbersome adjustments for string height and intonation, often necessitating multiple tools and numerous screws, increasing manufacturing time and complexity.
Innovation Solution
A bridge assembly featuring a rockable assembly body with a rounded rocker portion and a string height adjustment member that extends through the assembly body, allowing for single-tool adjustment of string height and intonation using a single adjustment member, integrated with a string anchor to simplify anchoring and reduce parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional bridges use multiple adjustment screws and separate components for string height and intonation adjustment, then adjustment precision can be achieved, but device complexity and number of parts increase
Solution Approach 1:
The patent combines multiple adjustment functions (string height adjustment and intonation adjustment) into a single bridge assembly that uses one adjustment screw. The bridge piece is integrated with the bridge plate, and the adjustment mechanism incorporates both height and intonation control features, reducing the total number of parts while maintaining adjustment precision.
Solution Approach 2:
The single adjustment screw serves multiple functions: it adjusts both the string height and the intonation by rockable movement of the bridge piece. This multi-functional design eliminates the need for separate adjustment mechanisms, reducing device complexity while preserving comprehensive adjustment capability.
2Adaptability or versatility
If conventional bridges require multiple tools for different adjustments, then specialized adjustment capability is achieved, but ease of operation deteriorates
Solution Approach 1:
The bridge assembly is designed so that a single adjustment screw can perform both string height adjustment and intonation adjustment. This universal adjustment mechanism allows users to make all necessary adjustments with one tool, greatly improving ease of operation while maintaining full adjustment versatility.
Solution Approach 2:
The bridge piece is designed to be rockable, allowing dynamic adjustment of both height and intonation through a single screw mechanism. This dynamic design enables the same component to serve multiple adjustment purposes, eliminating the need for multiple specialized tools.
3Reliability
If conventional bridges use separate components for anchoring strings, then secure anchoring is achieved, but manufacturing time increases
Solution Approach 1:
The patent integrates the string anchoring function directly into the bridge piece, which is itself integrated with the bridge plate. This consolidation of anchoring and adjustment functions into a single assembly reduces the number of separate components that need to be manufactured and assembled, thereby reducing manufacturing time while maintaining secure anchoring.

AI summary
A bridge assembly for a stringed instrument including an assembly body including a rounded rocker portion positionable against the stringed instrument. The assembly body is rockable on the stringed instrument. A string height adjustment member is connectable to the stringed instrument and extendable through the assembly body. When the rounded rocker portion of the assembly body is positioned against the stringed instrument, and the string height adjustment member extends through the assembly body and connects the assembly body to the stringed instrument, the string height adjustment member is operable to rock the assembly body on the stringed instrument via the rounded rocker member and adjust the height of a string resting on the assembly body. The bridge assembly can be used to adjust the height and intonation of, and to provide an anchor for, a string resting on the bridge assembly. A stringed instrument including the improved bridge assembly.
