Guitar Armrest Suction Attachment Isolates Soundboard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guitar armrests cause discomfort due to reduced blood circulation and affect sound quality by applying pressure on the soundboard, restricting its movement and damaging the guitar's finish.
Innovation Solution
A flexible, adjustable guitar armrest with suction cups that attaches to the guitar without contacting the soundboard, allowing for comfortable arm placement and maintaining sound quality, made from a durable yet washable rubber material with replaceable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If prior art guitar armrests attach to the guitar, then they provide arm support, but they put pressure on the soundboard which restricts soundboard movement and affects sound quality
Solution Approach 1:
The armrest is designed to attach exclusively to the lower bout of the guitar, extracting the support function away from the soundboard area. The curved contour specifically positions the armrest to contact only the lower bout surface, eliminating soundboard pressure while maintaining arm support functionality.
Solution Approach 2:
The lower bout serves as an intermediary attachment surface between the armrest and the guitar body. By utilizing the lower bout as the attachment location rather than directly supporting against the soundboard, the design mediates the support function to avoid harmful pressure on the soundboard while maintaining effective arm support.
2Reliability
If prior art guitar armrests attach firmly to the guitar, then they provide stable support, but they may damage the guitar's surface finish
Solution Approach 1:
The armrest features a curved contour with specific geometric properties designed to contact only the lower bout surface. This localized contact geometry ensures that pressure is distributed across a suitable area of the lower bout while completely avoiding contact with the more vulnerable soundboard surface, providing stable attachment without finish damage risk.
3Adaptability or versatility
If an armrest is designed to fit various guitar sizes, then it increases versatility, but it may compromise attachment firmness
Solution Approach 1:
The armrest is designed with a universal curved contour that can accommodate various guitar sizes and lower bout curvatures. The geometric design allows the armrest to conform to different guitar shapes while maintaining consistent attachment characteristics, enabling one design to serve multiple guitar types effectively.

AI summary
A guitar armrest designed to relieve the arm stress that a guitarist experiences in the Palmaris Longus muscle caused by the arm resting against the acoustic guitar's lower bout and soundboard side edge. It is made of a one piece injection-molded flexible rubber solid body, with a durometer so as to hold the weight of a guitarist's arm off of the front soundboard so as to prevent scratching and deadening of the sound projected therefrom. Replaceable suction cups extend through the body of the armrest such that their attachment buttons protrude from the armrest's top face and their suction disks protrude from the bottom face. The armrest is temporarily affixed to the lower bout of the guitar by suction means.
