Wind Chime Tube Connection Using Jump Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wind chimes require drilling and grinding to attach suspension cords, affecting their appearance, tone quality, and safety due to loose connections.
Innovation Solution
The use of jump rings inside wind chime tubes to secure suspension cords without drilling, utilizing limiting and connection structures like central holes, clamping slots, and mounting grooves to maintain cord position and prevent loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If drilling holes and installing grommets is used to connect suspension cords, then the connection strength is improved, but the appearance beauty deteriorates and manufacturing time increases
Solution Approach 1:
A connection piece is introduced as an intermediary component between the suspension cord and the wind chime tube. The connection piece includes a limiting portion that engages with the interior wall of the wind chime tube and a connection portion that secures the suspension cord, eliminating the need to drill holes in the wind chime tube itself while maintaining strong connections
Solution Approach 2:
The connection structure is divided into separate functional parts: a limiting portion for securing the connection piece to the tube interior, and a connection portion for attaching the suspension cord. This segmentation allows the connection piece to be installed without drilling the aesthetic wind chime tube surface
2Reliability
If drilling holes is used to attach suspension cords, then the connection is established, but the manufacturing time and labor increase due to grinding requirements
Solution Approach 1:
The connection piece serves as a pre-fabricated intermediary component that combines the limiting and connection functions. It can be installed in the wind chime tube without drilling or grinding operations, significantly reducing manufacturing time while maintaining reliable suspension cord attachment
Solution Approach 2:
The connection piece is prepared in advance with its limiting and connection portions already formed. This preliminary preparation eliminates the need for on-site drilling and grinding operations during wind chime assembly, reducing manufacturing time and labor
3Ease of operation
If pins are used to connect suspension cords in the form of pins, then the connection is simplified, but the tone quality deteriorates and safety hazards increase due to loosening
Solution Approach 1:
The connection piece acts as an intermediary that provides both simplicity and reliability. The limiting portion with engagement structures secures the connection piece firmly to the tube interior, preventing loosening during swinging, while the connection portion maintains the suspension cord in a stable central position for consistent tone quality
4Ease of manufacture
If suspension cords are not centrally positioned in wind chime tubes, then the installation is easier, but the tone quality deteriorates
Solution Approach 1:
The connection piece includes a limiting portion that engages with the interior wall at a predetermined location, automatically positioning the suspension cord at the central position of the wind chime tube. This engineered positioning mechanism achieves precise cord placement without requiring complex installation procedures
