Positionally Fixed Hose Clamp With Axial Positioning Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose clamps face challenges in maintaining alignment with sealing surfaces, leading to compromised seals and mechanical connections due to manual error, rotational instability, and damage to hose or duct materials, especially in automated installations.
Innovation Solution
A positionally fixed adjustable clamp with a circumferential band and position fixing legs, secured by mounting pads and a T-shaped position fixing band, ensures fixed radial and longitudinal alignment and rotational stability on the hose or duct, preventing misalignment and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hose clamp is manually installed at a roughly judged longitudinal distance from the end of the hose, then the installation process is simple and quick, but the alignment with the sealing surface is imprecise and error-prone
Solution Approach 1:
The clamp is pre-configured with positioning members (legs extending axially and bending over the connection end) that automatically establish the correct longitudinal distance from the hose end before installation. This preliminary positioning eliminates the need for manual measurement and judgment during installation, ensuring precise alignment with the sealing surface while maintaining simple installation procedures.
2Length of moving object
If a flat positioning portion extends over the end of the hose and bends to lie against the interior surface, then the clamp is positioned nearer to the connecting end, but the sealing surface alignment is compromised and surface damage occurs
Solution Approach 1:
The harmful interaction between the positioning portion and the hose surface is eliminated by extracting the damaging contact mechanism. Instead of having the positioning portion lie against or embed into the hose surface, the legs extend axially and bend over the connection end without contacting the sealing surface or inner surface, thus preventing scratches and damage while maintaining proper positioning.
3Adaptability or versatility
If the clamp is allowed to rotate circumferentially during adjustment and tightening, then the clamp can be adjusted to different orientations, but the alignment with the sealing surface is lost and the connection is compromised
Solution Approach 1:
The positioning members (legs extending axially and bending over the connection end) create a preliminary constraint that prevents circumferential rotation during adjustment and tightening. This anti-rotation mechanism is built into the clamp structure itself, counteracting the tendency to rotate before the clamp is fully tightened, thereby maintaining precise radial alignment with the sealing surface throughout the installation process.
4Manufacturing precision
If positioning members extend axially and bend over the connection end to limit axial movement, then the clamp position is fixed longitudinally, but the clamp may still rotate circumferentially and misalign with the sealing surface
Solution Approach 1:
The positioning functionality is merged into the clamp structure itself by integrating the legs as inherent components of the clamp assembly. The legs extend axially from the clamp body and bend over the connection end, combining longitudinal positioning and circumferential rotation prevention into a single integrated feature, ensuring both longitudinal and radial alignment reliability simultaneously.

AI summary
A hose or duct having and end with an adjustable clamp fixed in an enforced position thereon. The clamp includes a band which encircles the hose or duct. The band has an adjustable diameter operable to compress the hose or duct to form a fluid tight seal onto an exterior of a connection port. The adjustable clamp secured to the duct or hose by at least one mounting pad.
