Turning Peg Bracket With Changeable Panels For String Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
String instruments' turning peg structures are prone to damage from impact or dropping, leading to issues with adjusting string tightness and affecting performance quality, and existing metal replacements lack aesthetic appeal.
Innovation Solution
A turning peg structure with a bracket made from sturdy materials like wood, incorporating changeable panels and a connecting rod that drives a winding shaft assembly to adjust string tightness, enhancing structural strength and allowing for personalized ornamentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal material is used for the turning peg to replace wood or plastics, then the strength is improved, but the aesthetic appeal and personal style expression deteriorate
Solution Approach 1:
The turning peg is divided into two functional segments: a metal core component (adjustment stem and connecting rod) that provides structural strength, and a separate wooden panel component that provides aesthetic appeal. This segmentation allows each material to fulfill its optimal function without compromise.
Solution Approach 2:
The invention combines metal and wood materials in a composite structure where the metal adjustment stem and connecting rod provide mechanical strength, while the wooden panel attached to the turning peg provides aesthetic appeal and can be customized with personal style decorations.
2Shape
If wood or plastics is used for the turning peg, then the aesthetic appeal is maintained, but the structural strength deteriorates leading to damage from impact
Solution Approach 1:
The turning peg is divided into two functional segments: a metal core component (adjustment stem and connecting rod) that provides structural strength, and a separate wooden panel component that provides aesthetic appeal. This segmentation allows each material to fulfill its optimal function without compromise.
Solution Approach 2:
The invention combines metal and wood materials in a composite structure where the metal adjustment stem and connecting rod provide mechanical strength, while the wooden panel attached to the turning peg provides aesthetic appeal and can be customized with personal style decorations.
3Reliability
If the turning peg is made from sturdy material like metal, then the reliability is improved, but the ease of manufacture deteriorates due to customization requirements
Solution Approach 1:
The turning peg is divided into two functional segments: a metal core component (adjustment stem and connecting rod) that provides structural strength, and a separate wooden panel component that provides aesthetic appeal. This segmentation allows each material to fulfill its optimal function without compromise.
Solution Approach 2:
The invention makes the aesthetic component (wooden panel) replaceable and interchangeable, allowing users to change panels to express different personal styles. This dynamic customization capability is achieved through a mounting structure that allows easy attachment and detachment of different panel designs.

AI summary
A turning peg structure equipped with changeable faceplate to drive a winding shaft assembly of a string instrument to adjust the tightness of a string. The turning peg structure includes a bracket, at least one first faceplate, at least one second faceplate and a linking rod. The bracket includes a plate and a passage embedded in and run through the plate. The plate includes a first side and a second side opposite to the first side. The first faceplate includes a first connecting portion connected to the first side of the bracket. The second faceplate includes a second connecting portion connected to the second side of the bracket. The linking rod has one end located in the passage and another end engaged with the winding shaft assembly. Through the bracket, the turning peg structure does not lose string adjustment function due to damage thereof.
