Hose Securing Device With Elastic Sleeve And Thread Knob
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for filling large water tanks in boats and RVs, such as using garden hoses, often result in the hose popping out of the tank opening due to pressure, requiring manual holding and extending the filling time.
Innovation Solution
A hose securing device with a sleeve featuring a cleft that adjusts circumference, combined with a thread engagement knob, securely attaches to the hose and tank, ensuring the hose remains in place during filling by expanding to fit the hose and then narrowing to engage with the tank's threads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hose is inserted into a water tank opening, then the tank can be filled with water, but the pressure in the hose causes the hose to pop out of the opening
Solution Approach 1:
The device employs a dynamic mechanism where the sleeve can expand and contract. During insertion, the sleeve is in a compressed state to fit through the opening. Once in place, it expands to grip the hose securely, preventing it from popping out during filling operations.
Solution Approach 2:
The device is divided into functional segments: a sleeve for gripping the hose, thread engagement knobs for securing to the tank, and a shield for protection. This segmentation allows each component to perform its specific function effectively, with the sleeve specifically designed to maintain hose retention through its expansion capability.
2Reliability
If a user holds the hose to prevent it from popping out, then the hose remains in place, but a substantial amount of time is required to fill large water tanks
Solution Approach 1:
The device makes the hose retention self-service by mechanically securing the hose through the expandable sleeve and thread engagement knobs. Once installed, the device maintains hose retention automatically without requiring continuous manual intervention, allowing the user to simply monitor the filling process rather than constantly hold the hose.
Solution Approach 2:
The device acts as an intermediary between the hose and the tank opening. It provides a mechanical connection that transfers and maintains the connection stability, eliminating the need for direct manual holding while ensuring the hose remains securely in place throughout the filling operation.
3Reliability
If the sleeve circumference is increased to fit over the hose, then the hose can be secured, but the device cannot be inserted into the tank opening
Solution Approach 1:
The sleeve is designed with dynamic expansion and contraction capabilities. For insertion, the sleeve is compressed to a smaller circumference that allows it to pass through the tank opening. Once positioned, the sleeve expands to its larger circumference to securely grip the hose, thus resolving the contradiction between insertion ease and hose grip.
Solution Approach 2:
The device utilizes parameter changes in the sleeve's dimensional characteristics. The sleeve transitions between two states: a compressed state with reduced circumference for easy insertion, and an expanded state with increased circumference for secure hose gripping. This parameter transformation allows the device to satisfy both requirements sequentially.
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 device effectively prevents the hose from popping out of the tank, reducing the need for manual holding and speeding up the filling process by securely attaching to both the hose and tank.
Implementation Method 1
The cleft enables a circumference of the central aperture to be increased or decreased and allows an outer circumference to be increased or decreased. The width of the cleft can be increased by putting pressure on the first face and the second face of the cleft. After the pressure on the faces of the cleft has been released, the width of the cleft returns to its original width.

AI summary
A device for securing a hose to a holding tank is disclosed. The device includes a sleeve with a cleft running through it; a central aperture for holding a hose, an entry section for inserting the device into a mouth of the holding tank, a shield which covers the mouth of the holding tank, and a haft and pommel to assist with placement and removal of the device. The cleft enables a circumference of the central aperture to be increased or decreased and allows an outer circumference to be increased or decreased. In one embodiment, at least one thread engagement knob secures the entry section to the mouth of the holding tank.
