Sectioned Hose Radial Force Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sectioning hoses comprising a tube and a tube encasement often lead to misalignment and increased risk of plumbing mishaps, such as floods, due to longitudinal displacement of the tube encasement relative to the tube during cutting.
Innovation Solution
A method involving the formation of a ring of tensioned material around the outer circumference of the tube encasement, which induces radial forces to prevent longitudinal displacement of the tube encasement relative to the tube, allowing for precise sectioning without misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tube and tube encasement are cut without restraint, then the cutting process is simple and fast, but longitudinal displacement occurs causing misalignment and reliability issues
Solution Approach 1:
A ring of tensioned material is formed around the tube encasement before cutting to prevent longitudinal displacement. This preliminary restraint ensures that when the cut is made, the tube and tube encasement remain aligned, preventing misalignment and reliability issues without requiring complex real-time control mechanisms during cutting.
2Manufacturing precision
If a ring of tensioned material is formed to prevent displacement, then alignment precision is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The ring of tensioned material is applied in advance to the tube encasement to establish a restraint mechanism that maintains alignment during cutting. This preliminary action ensures precise alignment without requiring complex real-time adjustment mechanisms during the cutting process itself.
Solution Approach 2:
The ring of tensioned material acts as an intermediary element between the cutting tool and the tube encasement. It provides a simple mechanical restraint that prevents longitudinal displacement while allowing the cutting operation to proceed without complex control systems.
3Reliability
If the tube encasement is gripped and held during cutting, then displacement is prevented, but the process time increases due to gripping and bonding steps
Solution Approach 1:
The ring of tensioned material is formed around the tube encasement before the cutting operation begins. This preliminary restraint eliminates the need for time-consuming gripping and bonding steps during or after cutting, as the alignment is already secured in advance.
Solution Approach 2:
The mechanical gripping and bonding system is replaced with a tensioned material ring that provides continuous restraint through elastic tension. This substitution eliminates the need for separate gripping and bonding operations, reducing process time while maintaining alignment stability.

Function Achieved in This Case
The method significantly enhances the reliability of the hose by preventing misalignment and reducing the occurrence of plumbing mishaps, thereby improving consumer satisfaction.
Implementation Method 1
The ring of tensioned material acts to induce radial forces that prevent longitudinal displacement of the tube encasement relative to the tube
Implementation Method 2
The wrapped strip of material is then shrink processed, e.g. by heat shrinking, into a ring of tensioned material

AI summary
A system comprising a wrapping device that forms a ring of tensioned material by wrapping a material around an outer circumference of a tube encasement, and a cutting device that cuts through an entire cross-section of the ring of tensioned material, the tube encasement and a tube encased by the tube encasement, wherein the ring of tensioned material applies a first radial force onto the tube encasement and induces a second radial force from the tube encasement onto the tube.
