Guitar Wall Mount With Protected Cable-Actuated Neck Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing string instrument holders, particularly wall mounts and floor stands, suffer from complex mechanical structures prone to failure due to exposure of connecting cables and mechanisms, leading to functional impairments from dirt and damage.
Innovation Solution
A holder design with a cable guided completely or partially inside the anchor element, using a spring-connected cradle and arms, where the cable is protected from damage and soiling, allowing easy size adjustments and flexible attachment to different instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cable connecting the cradle and holding arms is exposed, then the structure is simpler and easier to manufacture, but the cable is prone to damage and soiling leading to functional impairments
Solution Approach 1:
The cable is nested inside the anchor element, which houses and protects it from external damage and soiling. This nesting arrangement allows the cable to remain protected while still transmitting mechanical forces effectively between the cradle and holding arms.
Solution Approach 2:
The anchor element serves as an intermediary structure that contains and protects the cable. By routing the cable through the anchor element, the system gains protection without requiring additional external cable housing or complex routing mechanisms.
2Reliability
If multiple mechanical components and joints are used to connect the cradle and holding arms, then the structure provides robust support, but the mechanism becomes susceptible to failure from dust and dirt accumulation
Solution Approach 1:
The harmful effect of dust and dirt on the cable is eliminated by extracting the cable from the external environment and placing it inside the protected anchor element. This removes the cable from exposure to contaminants that would cause functional impairments.
Solution Approach 2:
The cable is nested within the anchor element, creating a protected internal environment that shields the cable from dust and dirt. This nesting strategy allows the mechanical connection to remain robust while being resistant to environmental contaminants.
3Stability of the object's composition
If a rigid connecting rod is used instead of a cable, then the structure is more stable, but the weight increases and adaptability decreases
Solution Approach 1:
The connecting element is changed from a rigid rod to a flexible cable, fundamentally altering the mechanical parameters of the system. This parameter change allows for reduced weight and increased adaptability while maintaining stability through the cable's tension-based connection mechanism.
Solution Approach 2:
A flexible cable is used instead of a rigid connecting rod. The cable's flexibility allows it to conform to different configurations and reduces weight, while the tension it maintains provides sufficient structural stability for the holder's operation.
4Strength
If the holder structure is made complex to provide robust support, then the load-bearing capacity increases, but the ease of operation and handling decreases
Solution Approach 1:
The flexible cable allows the holder to operate with lower forces compared to rigid mechanical linkages. The cable's ability to flex and conform reduces the effort needed to manipulate the holder, improving ease of operation while maintaining sufficient load-bearing capacity through proper cable tensioning.

Function Achieved in This Case
The solution provides a simple, reliable, and adaptable holder with reduced weight and low operating forces, ensuring secure instrument retention and easy handling, while minimizing mechanical failures.
Implementation Method 1
a spring connected to the arms, cable, and/or cradle for urging the cradle into the upper position and the arms into the open position
Implementation Method 2
a cable at least mostly contained in the anchor element and connected between the arms and the cradle for moving the arms into the closed position on movement of the cradle into the lower position

AI summary
A holder for a musical instrument having a body and a neck has an anchor element, a cradle adapted to receive and support the body of the instrument and movable on the anchor element between a lower working position and an upper rest position, and a pair of arms pivotal on the anchor element between a closed position engaging around and securing the neck of the instrument supported on the cradle and an open position not surrounding the neck. Aa cable contained in the anchor element is connected between the arms and the cradle for moving the arms into the closed position on movement of the cradle into the lower position. A spring connected to the arms, cable, and/or cradle urges the cradle into the upper position and the arms into the open position so that setting the instrument body on the cradle moves same into the lower position and causes the arms to engage around the neck of the instrument.
