Liquid Hose Valve Connector for Damage-Free Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for connecting liquid hoses to valves often interfere and become damaged when passing through mounting openings in sanitary fittings, making the connection process difficult and prone to damage.
Innovation Solution
A device with a first thread for attachment to the valve, a receiving opening for the liquid hose, and a fastening device with a recess and securing sleeve to securely fasten the hose without the need for union nuts or compression fittings, allowing for easy attachment and preventing interference during screwing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional union nuts or compression fittings are used on fluid hoses, then the hose can be securely connected to the valve, but the hose and fittings interfere with each other and become damaged when passing through mounting openings
Solution Approach 1:
The connection system is divided into separate functional components: the device with receiving opening and fastening mechanism is separated from the hose, allowing the hose to pass through the mounting opening first, then be secured independently within the device housing
Solution Approach 2:
The hose is inserted into the receiving opening of the device housing, and the fastening element is inserted into the recess to secure the hose from the inside, creating a nested structure where the hose is contained within the device rather than connected externally with protruding fittings
2Reliability
If union nuts or compression fittings are used on fluid hoses, then the hose can be connected to the valve, but the hose interferes with the tightening process and rotation during installation
Solution Approach 1:
The problematic union nuts and compression fittings are extracted from the hose and replaced with a simplified system where the hose connects directly to the receiving opening of the device, eliminating the interfering external fastening components
Solution Approach 2:
Instead of fastening the hose to the valve first and then passing it through the mounting opening, the invention inverts the sequence by passing the hose through the opening first and then securing it within the device housing from the inside
3Ease of operation
If the fluid hose is inserted into the receiving opening, then the connection is simplified, but the hose may become loose or detached without a secure fastening mechanism
Solution Approach 1:
The fastening element is pre-positioned in the recess of the device housing, ready to secure the hose as soon as it is inserted into the receiving opening, ensuring immediate fixation without requiring additional tightening operations
Solution Approach 2:
The fastening element acts as an intermediary component that mediates between the hose and the device housing, providing secure retention by engaging the hose within the recess without requiring external nuts or fittings
