Hose hanger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Quick disconnect fittings on gas supply hoses are vulnerable to damage and contamination when disconnected, as they often rest on the floor during cleaning, and existing protective sleeves are insufficient for secure retention.
Innovation Solution
A hose retaining apparatus that attaches to the gas supply hose using a fastener like a hand screw or wing nut, featuring a hose end receptacle with snap engagement for quick disconnect fittings, which can be oriented to secure either female or male couplers, keeping the hose off the floor and protecting the fittings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing protective sleeves are used for quick disconnect fittings, then some protection is provided, but they are insufficient for secure retention and allow fittings to rest on the floor
Solution Approach 1:
The hose hanger apparatus features a receptacle that receives and nests the quick disconnect fitting within it. The fitting is captured inside the receptacle structure, preventing it from resting on the floor while providing secure retention through the nested configuration.
Solution Approach 2:
The hose hanger apparatus acts as an intermediary device between the quick disconnect fitting and the floor. Instead of the fitting直接接触 the floor, the receptacle serves as a mediating structure that supports and protects the fitting during disconnection.
2Ease of operation
If the hose is disconnected for cleaning, then cleaning access is improved, but the fittings become vulnerable to damage and contamination
Solution Approach 1:
The hose hanger apparatus provides preliminary protection to the quick disconnect fittings before they can be damaged or contaminated. By securing the fittings in the receptacle during disconnection, the system preemptively prevents harmful contact with the floor or other contaminants.
Solution Approach 2:
The hose hanger apparatus serves multiple functions: it retains the hose in an elevated position, protects the quick disconnect fittings from damage and contamination, and provides a secure storage location during cleaning operations. This multi-functionality addresses both cleaning accessibility and protection needs.
3Reliability
If a secure retention system is implemented for disconnected fittings, then protection is improved, but the device complexity increases
Solution Approach 1:
The hose hanger apparatus is divided into functional segments: the mounting mechanism that attaches to the hose, the receptacle that receives and retains the fitting, and the structural elements that provide support. This segmentation allows each component to perform its specific function while keeping the overall design manageable.

AI summary
The disclosed hose hanger apparatus is manually installable on a gas supply hose to secure and retain an end of the gas supply hose when the hose is disconnected from a gas appliance. The hose hanger apparatus is configured to engage with and protect a quick disconnect female coupler installed on the end of the gas supply hose. The hose hanger apparatus is also configured to engage with and accept a male quick disconnect nipple when installed in an opposite orientation on the gas supply hose.
