Self-Locking Guitar Hanger with Dynamic Swing Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current guitar hangers with fixed fork structures are prone to causing guitars to slip out or fall due to incorrect placement or external forces, leading to potential damage.
Innovation Solution
A guitar hanger apparatus featuring a fixed base, a hanger body with a fixing holder that moves down under the guitar's weight, and a self-locking mechanism driven by rotating shaft assemblies and swing arms, which locks the guitar in place using positioning casts, compression springs, and a silicon jacket with a rubber pad for secure holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed fork structure is used for hanging guitars, then the structure is simple and easy to manufacture, but the guitar is prone to slipping out or falling due to incorrect placement or external forces
Solution Approach 1:
The patent transforms the fixed fork structure into a dynamic self-locking structure. The swing arms can rotate around rotating shafts and are driven by compression springs to automatically adjust and lock the guitar in place. This dynamic mechanism allows the hanger to adapt to different guitar positions and external forces, preventing slippage while maintaining reasonable structural complexity through modular components.
Solution Approach 2:
The hanger employs a self-locking mechanism that automatically engages when a guitar is placed on it. The compression springs drive the swing arms to rotate and lock the guitar position without requiring manual intervention. This self-service feature enhances reliability by ensuring the guitar is securely fixed through its own weight, eliminating the need for complex external locking systems.
2Reliability
If a self-locking mechanism with multiple components is added to prevent guitar slippage, then the fixation reliability improves, but the manufacturing complexity and cost increase
Solution Approach 1:
The self-locking mechanism is divided into independent modular components: swing arms, rotating shafts, compression springs, and positioning casts. Each component can be manufactured separately using standard machining processes, facilitating ease of production and assembly. The segmented design allows for specialized manufacturing of each part while maintaining overall system reliability through their coordinated function.
Solution Approach 2:
The patent utilizes compression springs to convert the static structure into a dynamic one that responds to weight parameters. The springs are selected with specific force constants to provide adequate locking force for guitar weights, optimizing the balance between fixation reliability and manufacturing simplicity. By adjusting spring parameters rather than redesigning the entire mechanism, manufacturing ease is maintained while achieving reliable fixation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus securely fixes the guitar by its own weight, preventing displacement and damage with a simpler structure that facilitates mass production and manufacturer benefits.
Implementation Method 1
A compression spring is set in the positioning cast. Both of the positioning casts connect to the two branches of a Y-shaped folk in the hanger body through the compression springs respectively
Implementation Method 2
The end of the silicon jacket further contains a rubber pad
