Solution Overview
Problem
Firefighting personnel face difficulties in rolling multiple hoses of different sizes into coils due to the lack of devices that can simultaneously accommodate various widths, ensure drainage, and prevent the final hose coupling from being inadvertently coiled, leading to inefficiencies and hazards.
Innovation Solution
A multiple hose rolling device attachable to a vehicle, featuring adjustable guides, a closed dual-spindle system, and an electric motor for rotating the spindles, which ensures proper hose alignment, drainage, and prevents the final hose coupling from being coiled inadvertently, allowing for simultaneous rolling of hoses of different widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing hose rollers are used, then a single hose can be rolled, but multiple hoses of different sizes cannot be rolled simultaneously
Solution Approach 1:
The hose roller is designed with multiple spindles of different diameters and adjustable guides that can accommodate multiple hoses of different sizes simultaneously. The device performs the function of rolling different hose sizes on a single platform, making it universal for various hose types without requiring separate devices for each hose size.
Solution Approach 2:
The roller is divided into multiple independent spindles, each capable of holding and rolling a separate hose. This segmentation allows each spindle to be optimized for specific hose sizes while the overall system handles multiple hoses concurrently, improving both productivity and adaptability.
2Device complexity
If open-ended tines or spindles are used, then the device is simpler, but the coiled hose can be inadvertently displaced
Solution Approach 1:
The spindle design merges the simplicity of open-ended structures with the security of closed ends by incorporating retainers or stops that prevent hose displacement. The closed or semi-closed spindle design maintains structural simplicity while adding the necessary containment feature to secure the coiled hose during and after the rolling process.
3Device complexity
If no guide mechanism is provided, then the device is simpler, but hoses of different widths cannot be properly aligned
Solution Approach 1:
The guide mechanism features adjustable components that can be dynamically repositioned to match different hose widths. This dynamic adjustability allows the guides to adapt to various hose sizes, ensuring proper alignment and feeding onto the appropriate spindles without requiring a completely complex fixed structure for each possible hose size.
4Device complexity
If no drainage mechanism is provided, then the device is simpler, but water remains in the hose causing additional weight and potential hazards
Solution Approach 1:
The hose roller incorporates a drainage mechanism that allows water to drain from the hose before the hose is coiled onto the spindle. This preliminary drainage action removes excess weight and potential hazards before the coiling process begins, ensuring safer and more efficient hose handling without requiring complex post-coiling drainage systems.
5Device complexity
If the final end hose coupling can be inadvertently coiled, then the rolling process is simpler, but slack is induced and couplings can rotate repeatedly
Solution Approach 1:
The device incorporates a mechanism that prevents the final end hose coupling from being coiled onto the spindle in the first place. This preliminary protective action eliminates the risk of inducing slack or creating rotating couplings within the coil, maintaining hose coil integrity and preventing potential hazards associated with improperly coiled couplings.

AI summary
A multiple hose rolling device is provided that is readily attachable to a vehicle and rolls multiple hoses of different flattened widths simultaneously. The device includes guides that adjust to accommodate the widths of the hoses, a closed dual-spindle system to prevent inadvertent displacement of the coiled hose from the spindle, a mechanism for assuring the pre-drainage liquid and air from hose portions about to enter the coil, and a mechanism for preventing the final end hose coupling from inadvertently being coiled. The device may be positioned to the side of the vehicle with the spindles extending outwardly from the vehicle and includes an electric motor for rotating the primary spindle, which can be powered by its own battery or the vehicle's battery. Precisely positionable guides are provided for carefully separating and guiding several hoses of different flattened widths as they approach the spindles.
