Conical Hose Fastening Element for Quick Appliance Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening arrangements for hose lines on household appliance components require high assembly effort due to cumbersome attachment methods, often involving screws for securing the hose clamp to the receiving socket.
Innovation Solution
A conically tapering receiving opening in the securing element allows for simple and secure fixation of the hose line to the receiving socket without the need for additional tightening, with the securing element being designed as a one-piece fastening element that automatically fixes the hose line when inserted, and optionally using a hose clamp for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hose clamp is attached to the outer circumference of the receiving socket using a screw, then the hose line can be fixed to the receiving socket, but the assembly effort and complexity increase significantly
Solution Approach 1:
The invention extracts the hose clamping function from the receiving socket structure and integrates it into a separate securing element. This securing element is designed with a conically tapering receiving opening that automatically clamps the hose line when pushed onto the receiving socket, eliminating the need for separate hose clamp attachment operations and screws.
Solution Approach 2:
The conically tapering receiving opening in the securing element performs the clamping function automatically through its geometric design. As the hose line is pushed into the conical opening, the tapering walls naturally exert radial clamping force on the hose line, creating a self-clamping mechanism that requires no additional tightening operations.
2Reliability
If a screw is used to move the two ends of the hose clamp towards one another, then the hose clamp can secure the hose line, but the assembly time and effort increase
Solution Approach 1:
The invention replaces the screw-based mechanical tightening system with a geometric self-clamping system. The conically tapering receiving opening uses pure geometric form to generate clamping force automatically, substituting the complex screw-thread mechanical system with a simple conical geometry that achieves the same securing function without requiring rotational tightening operations.
Solution Approach 2:
The conical geometry of the receiving opening creates a self-actuating clamping mechanism. When the hose line is inserted and pushed into the conical opening, the geometry itself generates the radial clamping force needed to secure the hose line, eliminating the need for external tightening operations.
3Productivity
If a conically tapering receiving opening is used in the securing element, then the hose line can be fixed quickly and reliably, but the securing element design becomes more specific
Solution Approach 1:
The invention changes the geometric parameters of the receiving opening from a standard cylindrical shape to a conically tapering shape. This parameter change in the geometry creates the self-clamping function, where the tapering angle and conical form generate radial clamping forces automatically during the insertion process, enabling quick and reliable fixation.
Solution Approach 2:
The conically tapering receiving opening uses curved surfaces instead of flat or cylindrical surfaces. The conical geometry with its sloping walls creates a progressive clamping action as the hose line is inserted, where the curved surface area gradually engages the hose line and generates increasing radial clamping force throughout the insertion stroke.

Function Achieved in This Case
This solution significantly reduces assembly effort and ensures a secure, reliable, and quick attachment of the hose line to the receiving socket, minimizing production costs and ensuring a uniform clamping force for a tight seal.
Implementation Method 1
a receiving opening of the securing element facing the hose line is designed conically and tapers in cross-section in the direction in which the hose line is pushed on
