Hose Trolley Rotatable Ground Support for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hose trolleys are prone to falling over when hoses are pulled out at an angle, leading to instability and safety issues, and lack adequate support features for user convenience and stability on level surfaces.
Innovation Solution
A hose trolley design featuring a rotatable ground support element and a support stand that allows the trolley to transition between an operating position for stability and a driving position for mobility, with wheels that do not contact the surface in the operating position to prevent toppling and enhance turning capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hose trolley is supported only by wheels during operation, then mobility is improved, but stability deteriorates causing the trolley to topple when hose is pulled at an angle
Solution Approach 1:
The support stand is designed to be dynamically adjustable between retracted and extended positions. During mobility mode, the stand is retracted to allow free movement. During operation, the stand is extended to provide stability when the hose is pulled at an angle, preventing the trolley from toppling over.
Solution Approach 2:
The support stand serves multiple functions: it acts as a stabilizing leg during operational use, provides structural support for the hose reel mechanism, and can be adjusted or retracted when mobility is required. This multi-functionality resolves the contradiction between stability and mobility needs.
2Ease of operation
If the wheels are in contact with the ground during operation, then maneuverability is improved, but the tendency to fall over increases
Solution Approach 1:
The system dynamically adjusts the contact configuration with the ground. During operation, the support stand contacts the ground while wheels are elevated, providing stability. During relocation, the stand is retracted and wheels contact the ground for maneuverability. This dynamic reconfiguration eliminates the falling tendency during operation while maintaining maneuverability during relocation.
3Stability of the object's composition
If a fixed support structure is used, then stability is improved, but adaptability to different positions deteriorates
Solution Approach 1:
The support stand incorporates adjustable positioning mechanisms that allow it to be configured for different operational positions and angles. The stand can be extended, retracted, and positioned at various angles to accommodate different hose lengths, pull angles, and ground conditions, providing both stability and adaptability.
Solution Approach 2:
The support structure is divided into segmented, adjustable components rather than a single fixed element. This segmentation allows each component to be independently adjusted to achieve the optimal stable configuration for different operational scenarios, enhancing both stability and adaptability.

Function Achieved in This Case
The design significantly reduces the likelihood of the hose trolley toppling and enhances user safety and convenience by providing dynamic stability and easy maneuverability, while the rotatable ground support element and support stand allow for smooth hose handling and movement.
