Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current winding devices for hoses and straps are cumbersome, time-consuming, and expensive, requiring manual labor and vehicle intervention, with existing solutions being complex and unstable when used with motors.
Innovation Solution
A lightweight, inexpensive winding device with a rotationally symmetrical design featuring elongate legs that allows for easy mounting and operation on-site, using a rotation tool to wind hoses and straps both on a plane surface and in the air, with adjustable leg spacing and detachable lengthening elements for versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a winch is mounted on a lorry or truck to wind up hoses and straps, then the winding operation can be performed, but the work takes a long time and becomes expensive due to the need to bring the hose/strap to the winch
Solution Approach 1:
A portable winding device acts as an intermediary tool that can be brought directly to the hose/strap location. This device includes a winding drum with a coupling mechanism that attaches to the hose end, eliminating the need to transport the hose to a fixed winch on a vehicle.
Solution Approach 2:
The winding function is extracted from the fixed vehicle-mounted winch system and implemented in a portable, handheld device. This allows the winding operation to be performed at any location without requiring vehicle presence or hose transportation.
2Ease of operation
If a vehicle-mounted winch is used for winding hoses, then winding can be performed, but heavy work is required for the driver or persons to carry out the winding
Solution Approach 1:
The manual mechanical winding operation is replaced with a powered system. The portable device can be coupled to power sources such as portable electrical drills, air-driven tools, hydraulic motors, or battery-operated hand drilling machines, which provide the rotational force needed for winding without requiring manual physical effort.
3Ease of manufacture
If existing portable winding tools are used, then portability is achieved, but the construction becomes expensive and complicated with multiple parts
Solution Approach 1:
The winding device merges multiple functions into a single integrated structure. The main body houses both the winding drum and the coupling mechanism for attaching to the hose end, eliminating the need for separate components found in prior art devices. This unified design simplifies manufacturing while maintaining portability and functionality.
4Reliability
If a telescopic shank with multiple parts is used in a portable winding tool, then portability is achieved, but the winding becomes unstable when coupled to an electrical motor
Solution Approach 1:
The device is segmented into two main functional parts: a main body containing the winding drum and a separate coupling member that attaches to the hose end. This segmentation allows the coupling member to be optimally designed for motor coupling without compromising the stability of the winding drum, while still maintaining overall device portability.
