Guitar Bridge Assembly With Spherical Contact Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional guitar bridge assemblies require uniform bridge post heights for optimal contact, limiting adjustability and performance when the bridge is not parallel to the guitar body, reducing energy transfer and sound quality.
Innovation Solution
A bridge assembly with lower concave and upper convex contact surfaces on the bridge body and bridge posts, allowing for areal contact even in non-parallel orientations through tapered receiving passages and a locking cap system, ensuring secure attachment and adjustable height settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional bridge posts with planar support platforms are used, then the bridge can be mounted to the guitar body, but the bridge must be kept parallel to maintain optimal contact area, limiting adjustability
Solution Approach 1:
The patent replaces planar support platforms with spherical contact surfaces on the bridge posts. These spherical surfaces allow the bridge to be oriented at various angles while maintaining optimal areal contact through the curved geometry, resolving the contradiction between adaptability and contact area.
Solution Approach 2:
The patent introduces adjustable bridge posts with variable heights and orientations, transforming the static parallel mounting requirement into a dynamic system where the bridge can be adjusted to different orientations while maintaining optimal contact through the spherical interfaces.
2Ease of operation
If the bridge is oriented non-parallel to the guitar body, then player preference and playability are improved, but energy transfer and sound quality deteriorate due to reduced contact
Solution Approach 1:
The spherical contact surfaces on the bridge posts enable the bridge to maintain optimal areal contact with the posts even when oriented at non-parallel angles, thereby preserving energy transfer efficiency while allowing the bridge to be positioned for optimal playability.
3Area of stationary object
If uniform bridge post heights are required for optimal contact, then contact area is maximized, but height adjustability and versatility are reduced
Solution Approach 1:
The patent employs adjustable bridge posts where the height and orientation can be dynamically modified. The spherical contact surfaces ensure that optimal areal contact is maintained regardless of the adjusted height or orientation, allowing both contact area and adjustability to coexist.
Solution Approach 2:
The bridge posts are pre-configured with spherical contact surfaces that are designed to maintain optimal contact geometry across a range of positions, allowing the bridge to be adjusted to different heights and orientations while preserving contact area.
