Hose Clamp Clip Layout for Diameter Compensation and Stable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose clamps with evenly distributed clip elements face issues with variable hose diameter compensation, loose connections over time, and unpredictable release order leading to migration and poor positioning on the hose.
Innovation Solution
Incorporating at least two clip elements, where one is in direct contact with the hose surface and the other provides radial spacing to form a bulge, allowing for adjustable positioning and secure attachment without plastic deformation, with a latching mechanism for automatic detachment during tensioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If three clip elements are distributed evenly over the circumference on the clamp band, then the hose clamp can be fixed concentrically to the hose, but the preset diameter of the hose clamp must correspond to the diameter of the hose with limited compensation possibility
Solution Approach 1:
The clamp band is divided into multiple functional zones by distributing clip elements at different radial positions. The first clip element contacts the hose surface directly while the second clip element creates a radial distance, segmenting the clamping function into positioning and compensation zones that work together to achieve both precision and adaptability
Solution Approach 2:
The solution transitions from a single-plane clamping approach to a multi-dimensional arrangement by placing clip elements at different radial distances from the hose surface. This creates a radial dimension for compensation while maintaining circumferential positioning, allowing the clamp band to accommodate diameter variations without sacrificing concentric alignment
2Ease of operation
If the clamp band is tensioned by actuating the tensioning device, then the clamp band can be released from the clip elements, but the clip elements remain on the hose end without function and may become loose
Solution Approach 1:
The clip elements are pre-positioned on the hose end before the clamp band is tensioned. The first clip element is crimped to secure axial positioning while the second clip element is positioned radially outward. This preliminary arrangement ensures that when the clamp band is later tensioned and released from the clip elements, they remain securely positioned on the hose end without becoming loose or migrating
Solution Approach 2:
Different clip elements are given different functional qualities: the first clip element is designed for axial positioning with direct hose surface contact and crimped retention, while the second clip element is positioned radially outward to provide diameter compensation. This local differentiation ensures each clip element serves its specific function while maintaining reliable retention after tensioning
3Strength
If the clamp band is released from the clip elements during tensioning, then the clamp band can be tightened, but migration of the tensioning device in the circumferential direction may occur
Solution Approach 1:
The clamp band is segmented into multiple interaction zones with clip elements distributed at different radial positions around the circumference. This segmentation creates multiple anchor points that constrain the clamp band's movement in different directions, preventing circumferential migration of the tensioning device while allowing radial tightening
Solution Approach 2:
The clip elements are positioned asymmetrically at different radial distances from the hose surface rather than uniformly. The first clip element contacts the hose surface directly while the second clip element is positioned radially outward, creating an asymmetric arrangement that provides both tightening capability and circumferential stability by distributing constraint forces unevenly around the clamp band

AI summary
The invention relates to a hose clamp (1) comprising a clamping strip (10) and a tightening device (11) for tightening the clamping strip (10). A first clip element (12)that is arranged on the clamping strip (10) allows the hose clamp (1) to be secured to a hose (13) at an axially defined distance from a hose end (14). According to the invention, a second clip element (15) that is arranged on the clamping strip (10) places the clamping strip (10) at a distance (A) from the outer surface of the hose (13).
