Hose Clamp Clip Structure for Stable Pre-Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hose clamp technologies face issues such as insufficient rigidity for pre-positioning, damage to hoses due to sunken clips, and difficulty in tightening due to lack of radial and axial stability, leading to mounting challenges and potential separation during transportation.
Innovation Solution
A hose clamp with a springy winged structure and pawl mechanism that securely attaches to the hose via clips, allowing for diameter reduction without damaging the hose, and combining springy and fixed clips for enhanced radial and axial rigidity, enabling pre-positioning and stable mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If clips are sunken into the hose from the outer diameter, then the clamp can be positioned on the hose, but it becomes very difficult to mount the clamp and the clips cannot prevent radial movement during tightening
Solution Approach 1:
Instead of sinking clips from the outer diameter into the hose, the patent inverts the approach by using clips that engage with the hose from the outside without sinking, combining radial engagement for positioning with axial engagement for stability during tightening
Solution Approach 2:
The patent divides the clip structure into multiple functional segments: positioning clips for radial engagement and additional clips for axial stability, allowing each segment to perform its specific function without interfering with the other
2Device complexity
If a single clip holds the hose from one point, then the clamp can be attached, but the clamp cannot be fixed properly and cannot maintain position under excessive tightening force
Solution Approach 1:
The patent uses multiple clips distributed around the clamp band instead of a single clip, with each clip engaging the hose at different points to provide comprehensive positioning and stability during tightening
Solution Approach 2:
Different clips are positioned at specific locations around the hose with optimized engagement characteristics, providing localized grip strength where needed most during the tightening process
3Manufacturing precision
If holding process is required to position the clamp, then the clamp can be positioned accurately, but the mounting process is extended and becomes difficult in hard-to-reach areas
Solution Approach 1:
The clamp is designed to be self-positioning through its clip mechanism that automatically engages with the hose during tightening, eliminating the need for manual holding and allowing one-handed operation in hard-to-reach areas
Solution Approach 2:
The clips are pre-configured on the clamp band to automatically engage with the hose at the correct positions during tightening, performing the positioning function in advance without requiring separate manual intervention

AI summary
A hose clamp developed for hose structures used in many fields particularly in the automotive sector. The hose clamp includes a clamp band which surrounds the hose, a clamp housing which engages both ends of said clamp band, at least one positioner clip which limits radial and axial motion of the hose clamp on the hose, a wing with springy feature which is located on the positioner clip and allows diameter reduction of the hose clamp, a structure which couples the positioner clip to the hose by a plurality of serrations and does damage the hose.
