Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hose clamps with fixed nominal diameters lack adjustability and strength, leading to inefficiencies in force transmission and increased risk of injury and damage.
Innovation Solution
A hose clamp design featuring cold-formed hooks with lugs on overlapping band sections, allowing force transmission through transverse surfaces and incorporating reinforcement beads for enhanced stability and adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hooks are made taller to improve engagement, then the line of force application deteriorates and injury risk increases
Solution Approach 1:
The patent changes the geometric parameters of the hooks by cold-forming them to less than the thickness of the metal sheet, creating a compact hook height that maintains engagement reliability while improving the line of force application and reducing injury risk
Solution Approach 2:
The patent combines the hook structure with reinforcement beads formed from the same metal sheet material, creating a composite structure that provides both engagement functionality and structural strength without increasing hook height
2Strength
If hooks are cold-formed to increase strength, then hook height decreases improving force transmission, but manufacturing complexity increases
Solution Approach 1:
The patent merges the hook formation process with the reinforcement bead formation process, both being created through cold-forming operations on the same metal sheet in sequence, which distributes manufacturing complexity across integrated steps rather than adding separate complex assembly operations
Solution Approach 2:
The cold-forming process changes the physical parameters of the metal sheet by plastic deformation, locally hardening the material and creating the hook geometry in a single integrated operation that simultaneously achieves strength enhancement and geometric formation
3Stability of the object's composition
If the clamping band is reinforced with beads, then stability against buckling improves, but device complexity increases
Solution Approach 1:
The reinforcement beads are formed by shaping the metal sheet itself into a corrugated or beaded profile, using the thin metal film's inherent flexibility to create geometric reinforcements that add stability without requiring separate rigid structural elements
Solution Approach 2:
The reinforcement beads introduce controlled curvatures and radial projections into the clamping band structure, creating geometric features that resist buckling through shape-dependent mechanical properties rather than through material property changes or additional components
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 design enhances force transmission efficiency, reduces injury and damage risk, and allows for adjustable diameter settings through interlocking hooks and reinforcement, improving the hose clamp's overall strength and stability.
Implementation Method 1
the hooks are stamped out of the clamping band, are strongly cold-formed when pressed to less than the thickness of the metal sheet

AI summary
The hose clamp described herein consists of a clamping band (10) with overlapping band sections in the closed state of the hose clamp, on which hooks (12, 19) are arranged for closing the hose clamp, and with a tightening device (15) arranged in the outer band section for tightening the hose clamp around an object to be clamped. The hooks (12, 19) are stamped out from the clamping band under cold working and each have a lug (21, 25). In the closed state of the hose clamp, the lug (21) of a hook (12) arranged on the inner band section and the lug (25) of a hook (19) arranged on the outer band section engage over each other, and the force is transmitted via transverse surfaces (27, 32) of the hooks (12, 19) that are in contact with each other.
