Collared Hose Retainer Bracket for Secure Opening Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of effective solutions to securely hold collared hoses in place within openings, particularly in confined spaces like aircraft fuel tanks, leading to safety hazards and inefficiencies during maintenance tasks.
Innovation Solution
A removable hose holder with a hose engagement portion and perimeter engaging portions that surround the hose and engage with the structure's rim to securely hold the hose in place, providing stability and preventing dislodgment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If duct tape is used to attach the hose to the access opening, then the hose can be held in place, but the hose is easily damaged and can fall out easily
Solution Approach 1:
The patent introduces a bracket as an intermediary device between the hose and the access opening. The bracket has a U-shaped configuration that cradles the hose collar and engages with the opening, providing secure retention without directly attaching to the hose itself. This mediator protects the hose from damage while ensuring reliable retention.
2Device complexity
If no retaining system is used for the collared hose, then the device complexity is reduced, but the hose can become dislodged and become a safety hazard
Solution Approach 1:
The retaining system is segmented into distinct functional portions: a U-shaped bracket portion for cradling the hose collar, and engaging portions for securing to the access opening. This segmentation allows each portion to be optimized for its specific function while keeping the overall device relatively simple.
3Reliability
If a hose holder is inserted into the opening to hold the hose, then the hose is secured in place, but the hose holder itself needs to be held securely within the opening
Solution Approach 1:
The patent merges the hose-cradling function and the opening-engagement function into a single integrated bracket structure. The U-shaped bracket simultaneously cradles the hose collar and has engaging portions that secure to the access opening, eliminating the need for separate retention mechanisms.

AI summary
A hose holder for holding a hose inside an opening in a structure is disclosed. The hose holder includes a hose engagement portion configured to surround at least a portion of a hose and perimeter engaging portions joined to the hose engagement portion for engaging the portions of the structure adjacent to the opening into which the hose is inserted and holding a hose within the opening.
