Hinged Hose Clip Guard With Kink Protection and Easy Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective devices for hose clips are either costly to manufacture due to the need for different plastics with varying elasticity and stiffness, or they compromise on assembly ease and protection by requiring flexibility and reinforcement, and can damage sterile packages.
Innovation Solution
A protective device with a plastic body comprising two ring segments connected via a hinge-like mechanism, allowing for high stiffness and easy assembly, and featuring a kink protection design to prevent hose kinking and contamination, with optional catch mechanisms and flexible links for enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective body is made from two different plastics with different elasticity and stiffness, then the protective function is improved, but the manufacturing cost increases
Solution Approach 1:
The patent applies local quality by creating a protective body with spatially varying properties through integrated mouldings. The radially oriented mouldings in the clamping region provide localized stiffness and protection where needed, while other regions maintain appropriate flexibility. This is achieved through injection moulding techniques that create varying wall thicknesses and structural features in different areas of the single-piece protective body, eliminating the need for multiple materials while maintaining the protective function.
2Ease of operation
If the protective body has high elasticity to facilitate assembly, then the ease of assembly is improved, but the protective function deteriorates
Solution Approach 1:
The patent applies dynamics by designing the protective body with regions of varying flexibility. The integrated mouldings create areas that can deform elastically during assembly to facilitate installation over the hose clip, while other regions maintain higher stiffness to provide protective function. The radially oriented mouldings in the clamping region provide structural support, while the overall design allows for controlled deformation during the assembly process.
3Ease of operation
If the band requires flexibility to be wound around the hose clip, then the ease of assembly is improved, but the stiffness in the moulding region deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the protective body into functional zones through integrated mouldings. The radially oriented mouldings create distinct segments that provide localized stiffness in the clamping region, while the overall band structure maintains flexibility for assembly. The mouldings are integrated into the single-piece construction, creating a segmented structural pattern that distributes flexibility and stiffness requirements across different regions of the protective body.

AI summary
A protective device (5, 5″, 5″, 5′″, 5″″) is provided for a hose clip (4) that connects a hose end (2) to a hose connection (3). The protective device includes a protective body (8, 8′, 8″, 8′″, 8″″) made of a plastic. In the assembled state, the protective body (8, 8′, 8″, 8′″, 8″″) surrounds the circumference of the hose clip (4) and accommodates the hose clip (4) at least in its clamping region via a radially oriented molding (32), and covers the hose clip (4) over the width thereof extending in the longitudinal direction of the hose connection (3). The protective body (8, 8′, 8″, 8′″, 8″″) has ring segments (9, 10) that can be connected to one another at their free ends (12, 13), and the segments are connected moveably to one another at their ends (14, 17) facing away from the free ends (12, 13).
