Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tensioning strap is used to mount the ventilation air duct hose, then the hose can be secured to the ventilation system, but the mounting process becomes labor-intensive and time-consuming
Solution Approach 1:
The coupling element is designed to be movable between a first position (for securing the hose) and a second position (for releasing the hose). This dynamic mechanism allows quick installation by simply pushing the hose into the fitting, eliminating the time-consuming process of tightening tensioning straps while maintaining reliable securing when in the first position.
Solution Approach 2:
The coupling element automatically secures the hose when pushed into the fitting, requiring no additional tightening actions. The elastic deformable connection provides automatic engagement, and the coupling element's movable design allows automatic locking in the first position, making the mounting process self-service and significantly reducing installation time.
2Reliability
If a tensioning strap is used to secure the ventilation air duct hose, then the hose can be attached to the ventilation system, but the air seal becomes sub-optimal leading to energy loss
Solution Approach 1:
The fitting incorporates a sealing arrangement specifically at the interface where the ventilation air duct hose meets the fitting. This localized sealing quality ensures an optimal air seal at the critical connection point, preventing energy loss from air leakage while maintaining the attachment function. The sealing arrangement is integrated into the fitting structure, providing both secure attachment and energy efficiency.
3Reliability
If a complex coupling mechanism is used to secure the ventilation air duct hose, then the attachment can be more secure, but the number of components increases
Solution Approach 1:
The coupling element is integrally formed with the wall of the fitting, combining what would traditionally be separate components (the coupling mechanism and the fitting body) into a single integrated structure. This reduces the total number of components while maintaining the securing function. The elastic deformable connection is also integrated into the fitting, further simplifying the overall device complexity.
Solution Approach 2:
The coupling element serves multiple functions: it secures the hose in the first position, allows quick release in the second position, and works with the elastic deformable connection to provide both attachment and sealing functions. This multi-functionality reduces the need for separate components, simplifying the overall device while maintaining reliable securing.
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
Facilitates quick and easy installation of ventilation air duct hoses while improving air tightness, reducing the number of components, and lowering energy consumption by minimizing air leakage.
Implementation Method 1
The fitting preferably comprises an elastically deformable connection between the coupling element and the wall. This elastically deformable connection has the advantage that this connection is resilient. Such a resilient connection allows the coupling element to be urged back into one of the first or the second position

AI summary
A fitting for coupling a ventilation air duct hose to a ventilation system, wherein the fitting has a first open outer end and a second open outer end to be coupled to the ventilation system, comprising: a wall bounding a channel which extends between the first open outer end and the second open outer end and in which the ventilation air duct hose is arrangeable; a coupling element which is connected pivotally to the wall so that the coupling element is pivotable between a first state and a second state, wherein the coupling element has a first tongue and a second tongue which extend in opposite directions relative to each other; the first tongue comprises a coupling surface which extends into the channel and is provided to couple the ventilation air duct hose to the fitting in the first state, and is configured to pivot the first tongue outward in order to move the coupling element into the second state in order to uncouple the ventilation air duct hose.
