Hose Clamp Pre-Positioning Fixing Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing hose clamps to hose ends are prone to assembly errors and can potentially damage the hose pipe stub, with a need for a secure and easy-to-assemble pre-fastening solution that prevents twisting and axial displacement.
Innovation Solution
A system featuring a fixing part with U-shaped elements connected to the hose end, allowing the hose clamp to be securely positioned and fixed against axial and radial displacement, with the fixing part remaining non-functional after tightening, utilizing releasable snap-in or latching connections and deformable parts for easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hose clamp is fastened to the hose end using conventional methods, then the connection is secure, but assembly errors may occur and the hose pipe stub may be damaged
Solution Approach 1:
The hose clamp is pre-positioned on the hose end before final assembly, with fixing parts temporarily securing it in place. This preliminary positioning ensures correct placement and prevents assembly errors while eliminating the risk of damaging the hose pipe stub during the tightening process
2Productivity
If the hose clamp is pre-assembled at a distributor, then it is ready for final assembly, but it may become restricted or blocked
Solution Approach 1:
The fixing parts are designed to provide temporary restraint during pre-assembly while allowing the hose clamp to remain dynamically adjustable. The U-shaped elements and connecting elements enable the clamp to be positioned and secured without permanent restriction, maintaining ease of operation during final assembly
3Manufacturing precision
If a complex fastening system is used to prevent twisting and axial displacement, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The fastening system is segmented into simple, modular components: U-shaped elements with connecting elements that attach to the hose end, and fixing parts that secure the hose clamp. This segmentation achieves precise positioning (preventing twisting and axial displacement) through simple, easy-to-manufacture parts rather than a complex integrated system

AI summary
A system for pre-positioning a hose clamp (2) on a hose end (24) includes: a) a fixing part (1′) which is connected non-releasably to an annular segment of the hose clamp (2) and is fastened to the hose end (24), and b) one or more fixing parts (1, 1″) which each have a U-shaped element which, fastened to the hose end (24), is directed with its open side (3) to the hose surface. The web (6) connects the two U-legs (4, 5) and extends axially and parallel to the hose surface. The U-leg (4), which lies closest to the hose end (24), has a connecting element (7) for attaching the U-shaped element to the end face of the hose end (24). The U-shaped element is configured in such a way that the hose clamp (2), which is pulled on to the hose end (24), is fixed releasably in the intermediate space (8) of the U-shaped element by way of an annular segment of the hose clamp in such a way that the hose clamp (2) is released from the fixing when tightened. The fixing part (1) remains without function on the hose end (24) after the hose clamp (2) has been tightened.
