Hose Clamp with Expansion Restricting Section for Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose clamps suffer from assembly defects and fluid leaks due to oblique assembly and enlarged gaps between clamp body ends, leading to inefficient hose tightening and potential fluid leakage.
Innovation Solution
A hose clamp design featuring a clamp body formed by bending a strip-shaped leaf spring material with operation sections that expand in diameter using elastic deformation, incorporating a locking section, engagement portion, expansion restricting section, and tilt prevention sections to maintain proper alignment and prevent divergence during tightening, ensuring secure assembly and leak prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the locking section is engaged with the engagement portion to maintain the clamp body in a diameter expansion state, then the clamp body can be temporarily assembled, but at the time of release, both operation sections may diverge in opposite directions causing oblique assembly and enlarged gaps
Solution Approach 1:
The expansion restricting section is designed to preemptively counteract the diverging tendency of operation sections when the locking section disengages from the engagement portion. By providing frictional resistance before divergence occurs, it prevents oblique assembly and maintains proper alignment of the clamp body with the hose throughout the tightening process.
Solution Approach 2:
The expansion restricting section acts as an intermediary element between the operation sections, providing a controlled frictional interaction that mediates the release process. This intermediary mechanism ensures that operation sections diverge smoothly without causing misalignment or gap enlargement.
2Productivity
If the operation sections diverge in opposite directions during release, then the clamp body can tighten the hose, but the gap between end portions is enlarged causing assembly defects and fluid leaks
Solution Approach 1:
The expansion restricting section provides preliminary frictional resistance to operation sections during the release process, preventing excessive divergence that would cause gap enlargement. This ensures the clamp body maintains proper contact with the hose throughout tightening, preventing assembly defects and fluid leaks while still achieving the necessary tightening function.
3Adaptability or versatility
If the clamp body is expanded in diameter using elastic deformation, then the hose can be inserted, but the operation sections may diverge causing oblique assembly
Solution Approach 1:
The expansion restricting section is designed to counteract the diverging tendency of operation sections that occurs during and after diameter expansion. By providing frictional resistance, it ensures that the clamp body maintains proper alignment with the hose throughout the expansion and tightening process, preventing oblique assembly while preserving the necessary adaptability for hose insertion.
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 design effectively prevents assembly defects and fluid leaks by maintaining proper alignment and sealing during hose tightening, ensuring a secure and leak-free connection between the hose and connection pipe.
Implementation Method 1
the clamp body is expanded in diameter by using elastic deformation by bringing the pair of operation sections close to each other
Implementation Method 2
tightening of a hose is made possible by diameter reduction by an elastic restoring force of the clamp body

AI summary
A hose clamp for preventing a leak during tightening of a hose includes a clamp body of a strip-shaped leaf spring material with an annular shape, and a pair of operation pieces. The clamp body maintained in a diameter expansion state by a locking claw of the operation piece engaged with an engagement concavity of the other operation piece. The engagement released by bringing the operation piece close to the other operation piece and moving the operation piece in the opposing direction in an axial direction of the clamp body, whereby reducing the clamp body diameter. An expansion restricting piece restricts divergence of both the operation pieces in opposite directions in the axial direction of the clamp body. Further, a tilt prevention section which prevents the clamp body from being obliquely assembled to a hose during tightening of the hose is provided.
