Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crimp rings face challenges in achieving secure, leak-free connections due to difficulties in precise positioning relative to barbs or grooves on fittings, often requiring additional labor and non-standard tools, and struggle to accommodate various tubing diameters and thicknesses.
Innovation Solution
A dual-section crimp ring design with a longer, thicker first section and shorter, thinner second section, featuring a rolled edge for precise positioning and an annular groove for flexibility, allowing for easy compression using standard tools and ensuring secure sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a crimp ring is made with sufficient overall length to enable automatic positioning relative to barbs or grooves, then positioning accuracy is improved, but the crimp ring becomes difficult to compress uniformly
Solution Approach 1:
The crimp ring is divided into two distinct sections: a first section with greater thickness and shorter axial length for compression, and a second section with lesser thickness and greater axial length for positioning. This segmentation allows each section to perform its specific function optimally without compromising the other.
Solution Approach 2:
Different sections of the crimp ring are given different thicknesses to optimize their respective functions. The first section has greater thickness to provide structural integrity during compression, while the second section has lesser thickness to enable flexible positioning over barbs or grooves.
2Reliability
If prior art crimp rings use non-standard crimping tools to achieve proper compression, then compression effectiveness is improved, but device complexity and cost increase
Solution Approach 1:
The first section of the crimp ring is designed with dimensions and properties that make it compatible with standard crimping tools used in the industry. This allows the crimp ring to be universally applied without requiring specialized or non-standard tools, reducing complexity and cost.
3Ease of operation
If the crimp ring is made thinner to facilitate compression, then ease of compression is improved, but the ability to provide secure sealed engagement deteriorates
Solution Approach 1:
The crimp ring is divided into two distinct sections: a first section with greater thickness for providing structural integrity and sealed engagement, and a second section with lesser thickness for facilitating compression and positioning.
Solution Approach 2:
Different sections of the crimp ring are given different thicknesses to optimize their respective functions. The first section has greater thickness to ensure secure sealed engagement, while the second section has lesser thickness to enable easy compression.
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 dual-section crimp ring construction enables rapid, universally applicable, and leak-free connections across various tubing diameters and fittings, simplifying installation and eliminating prior art's positioning and compression issues.
Implementation Method 1
The rolled edge provides a friction fit within the flexible tube or conduit to prevent slippage during installation
Implementation Method 2
the crimp ring is peripherally surrounded by a crimping tool which is employed to physically compress the crimp ring into the flexible tubing for causing the diameter of the crimp ring to be reduced
