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

VSEngineering 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

Engineering Contradiction:
Improvewinding speedVSAvoidtime to bring hose to winch
Core Design Contradiction:
ProductivityVSLoss of time

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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

Engineering Contradiction:
Improveease of winding operationVSAvoidphysical effort required
Core Design Contradiction:
Ease of operationVSForce

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If existing portable winding tools are used, then portability is achieved, but the construction becomes expensive and complicated with multiple parts

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidnumber of parts
Core Design Contradiction:
Ease of manufactureVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improvewinding stabilityVSAvoidmulti-part construction
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation
