Hose Clamp Rivet Attachment for Secure Hose Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose clamp positioning devices face issues with securing the clamp firmly on hoses, as they either require plastically deformable materials that can become loose or rely on friction, leading to unintentional detachment during handling or transport.
Innovation Solution
A hose clamp device featuring a flat holding element with a radially projecting fastening pin that pierces the hose wall, forming a rivet-like connection, which provides secure attachment and is enhanced by using materials like thin metal sheets, plastics, or soft metals for the holding element and fastening pin, allowing for durable and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If claws are designed to deflect towards each other after penetrating the hose wall to achieve a staple-like state, then the positioning device can be easily attached to the hose, but the claws may become loose again if carelessly removed during transport
Solution Approach 1:
The positioning device is divided into separate functional elements: the clamp band with holding elements and the fastening pins. This segmentation allows the fastening pins to independently penetrate the hose wall and form rivet heads, creating secure anchor points that prevent the entire device from becoming loose during transport while maintaining ease of attachment.
Solution Approach 2:
The fastening pins are designed to form rivet heads on the outer surface of the hose before final clamping occurs. This preliminary action of creating anchored rivet heads ensures that the positioning device is firmly secured to the hose end before any tensile loads are applied, preventing unintentional loosening during transport and handling.
2Strength
If high-strength, slightly or poorly plastically deformable material is used for the claws, then the material strength is improved, but the holding force relies solely on friction which may cause the clamp to come loose easily
Solution Approach 1:
The fastening pins form rivet heads on the outer surface of the hose before final clamping. This preliminary action creates mechanically anchored connection points that provide reliable holding force independent of friction, allowing the use of high-strength, poorly plastically deformable materials without risking loosening during transport.
Solution Approach 2:
The positioning device combines different materials with complementary properties: the clamp band uses high-strength, poorly plastically deformable material for structural integrity, while the fastening pins use softer, more plastically deformable material that can easily form rivet heads through plastic deformation, creating a composite structure that achieves both strength and reliable holding force.
3Reliability
If a rivet-like connection is formed by piercing the hose wall with a fastening pin, then the holding force and security of attachment are improved, but the device complexity increases
Solution Approach 1:
The fastening pin integrates multiple functions into a single element: it serves as both the piercing tool and the rivet formation tool. The pin penetrates the hose wall and forms rivet heads on both the inner and outer surfaces in one continuous action, combining piercing and riveting functions that would otherwise require separate operations or components, thus maintaining simplicity while achieving secure attachment.
Solution Approach 2:
The fastening pin is designed to automatically form rivet heads during the piercing process itself. As the pin is inserted through the hose wall, the deformation of the pin material during penetration automatically creates the rivet heads without requiring additional tools, operations, or components. This self-service approach achieves reliable rivet-like connections while minimizing device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures a secure and durable attachment of the hose clamp to the hose, preventing unintentional loosening, even under tensile loads, and simplifies the assembly process by using materials that can form rivet heads or holes as needed, ensuring a captively connected clamp.
Implementation Method 1
a rivet head can be formed on the fastening pin in the radial direction on the outside of the holding element and on the inside of the hose
Implementation Method 2
the fastening pin is made of a soft metal... Soft metals such as aluminum can easily be plastically deformed, making it easy to form rivet heads

AI summary
The invention relates to a device for positioning a hose clamp (1) on a hose (4), wherein the hose clamp (1) has at least one clamp band (2) which is wound tangentially around an imaginary longitudinal axis in an approximately annular shape and spaced radially apart, and which has a clamping device (3). The objective was to improve the holding forces of a device of this type. This objective is achieved by the device having a flat retaining element (5) projecting axially to the clamp band (2) and by the device further having a fastening pin (6) which projects radially inwards through the flat retaining element (5), wherein the fastening pin (6) can be inserted through the wall of a hose (4) and wherein a rivet head (6A, 6B) can be formed on the fastening pin (6) in a radial direction on the outside of the retaining element (5) and on the inside of the hose (4).
