Solution Overview

Problem

Existing hose winding devices for fire brigade operations are limited by their inability to navigate unpaved terrain, requiring heavy trucks and multiple workers to transport and deploy pump units and hoses, restricting accessibility and efficiency in rough terrain environments.

Innovation Solution

An all-terrain vehicle equipped with a lifting unit, including a lifting mast and fork carriage, and a hose winding device that allows for off-road mobility, enabling the transportation and deployment of hoses and pump units in challenging environments, with features like hydraulic adjustment and a chain drive for enhanced traction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a heavy truck with a large container is used to transport the hose winding device, then the container can be transported, but the vehicle can only travel on paved roads and compacted paths

Engineering Contradiction:

Improveterrain accessibilityVSAvoidvehicle weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The system is divided into separable components: the hose winding device can be detached from the container and transported independently on the all-terrain vehicle, while the container remains on the heavy truck. This segmentation allows the lightweight all-terrain vehicle to access rough terrain without requiring the entire system to be transported together.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The all-terrain vehicle acts as an intermediary transport means for the hose winding device, bridging the gap between the heavy truck (which can only travel on paved roads) and the deployment location (which may be inaccessible by heavy vehicles). This intermediary solution enables operational flexibility in rough terrain.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the hose winding device is integrated with the container, then the device is stable, but the container cannot be separated for independent transport

Engineering Contradiction:

Improvetransport flexibilityVSAvoiddevice-container integration

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system transitions from a static integrated configuration to a dynamic separable configuration. The hose winding device can be mounted on the container when stability is needed, or detached and mounted on the all-terrain vehicle when transport flexibility is required. This dynamic reconfigurability resolves the contradiction between stability and transport flexibility.

Inventive Principle:

Principle #15Dynamics

3Reliability

If a hydraulically driven winch is used to place the pump in water, then the pump can be safely positioned, but the container must be positioned within reach of the winch's maximum length

Engineering Contradiction:

Improvepump positioning safetyVSAvoidcontainer positioning flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The all-terrain vehicle with the hose winding device acts as an intermediary between the container and the pump. It can transport the pump to locations beyond the winch's maximum reach from the container, extending the operational range while maintaining safe and controlled pump positioning through the winding device.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Ease of operation

If multiple personnel are required to carry the pump unit and hoses, then the equipment can be transported, but at least two to four workers are needed

Engineering Contradiction:

Improveequipment transportabilityVSAvoidnumber of personnel

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

Manual carrying of the pump unit and hoses by multiple personnel is replaced with mechanical transport systems. The all-terrain vehicle with the hose winding device mechanically transports the pump unit, while the winding device mechanically lays and retrieves hoses, eliminating the need for multiple workers to manually handle the equipment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
