Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamps are not suitable for secure and easy installation and removal of tubes onto fittings without separating the tube and fitting, lacking a simple and cost-effective solution for crimpable separable connections.
Innovation Solution
A crimpable separable tubing clamp design featuring an inner band portion detachably attached to an outer band portion, allowing installation and removal without separating the tube and fitting, utilizing an Oetiker ear with parallel leg portions, a bridge, and support hooks for secure crimping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing clamp designs are used, then secure clamping is achieved, but installation and removal require separating the tube and fitting
Solution Approach 1:
The clamp is divided into two separate band portions: an inner band portion and an outer band portion. The inner band portion remains clamped around the tube while the outer band portion can be independently removed and reattached, enabling easy installation and removal without separating the tube from the fitting.
Solution Approach 2:
The inner band portion is positioned within the outer band portion, creating a nested configuration. The inner band portion serves as the core clamping element while the outer band portion provides additional support and enables the separable connection mechanism.
2Reliability
If traditional crimpable clamps are used, then secure connection is achieved, but the tube and fitting must be separated for removal
Solution Approach 1:
By segmenting the clamp into inner and outer band portions, the invention maintains secure connection through the crimped inner band while enabling convenient removal by detaching only the outer band portion, which is held by frictional engagement rather than permanent deformation.
3Ease of operation
If separable clamp designs are implemented, then easy installation/removal is achieved, but connection security may be compromised
Solution Approach 1:
The nested configuration ensures that the inner band portion, which provides the primary clamping force and secure connection, remains permanently attached to the tube. The outer band portion is nested within and can be independently removed, maintaining connection security while enabling ease of operation.
Solution Approach 2:
The inner band portion is pre-crimped onto the tube to establish secure connection before the outer band portion is attached. This preliminary action ensures that the critical clamping function is already secured when the separable outer band is engaged.

AI summary
A crimpable compression clamp that secures a tube onto a fitting and is able to be installed and removed without having to separate the tube and the fitting from each other. The crimpable compression clamp includes an inner band portion and an outer band portion. The inner band portion is detachably attached in the outer band portion so as to allow the crimpable compression clamp to be installed and removed without having to separate the tube and the fitting from each other by merely separating the outer band portion and the inner band portion from each other.
