Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing hose guides for vehicles, particularly in painting and washing, often get stuck in obstacles like wheels or bodywork, requiring constant adjustment and limiting user mobility, especially when wheels are far from the vehicle's front and rear.

Innovation Solution

A flexible pipe guide equipped with a handle, base, and magnet, allowing secure attachment to metal grates, with removable connections and a male-female fitting system for easy handling and orientation, ensuring the hose slides smoothly without relying on wheel positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional wedges are used to guide the hose, then the hose can slide without getting stuck in wheels, but the device becomes impractical when wheels are far from the vehicle ends and requires constant user adjustment

Engineering Contradiction:

Improvehose guidance stabilityVSAvoiduser mobility and convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical wedge system (which relies on physical insertion into wheels) with a magnetic field-based attachment system. The base unit with magnet attaches to metal surfaces through magnetic attraction, eliminating the need for mechanical wedging into wheels and providing reliable hose guidance without requiring wheel positioning.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention changes the attachment parameter from mechanical insertion depth (wedge in wheel) to magnetic field strength and metal surface proximity. This allows the guide to be positioned anywhere near metal surfaces without requiring specific geometric fitment, thereby improving ease of operation while maintaining reliability.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If wedges are fixed into vehicle wheels to ensure hose stability, then the hose guidance is reliable, but the device cannot be used when there are no wheels available (e.g., painting loose body parts)

Engineering Contradiction:

Improvehose guidance stabilityVSAvoidapplicability to different vehicle painting scenarios

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The base unit with magnet provides a universal attachment mechanism that works on any metal surface regardless of vehicle type or painting scenario. Unlike wheel-specific wedges, this magnetic attachment can be used for painting complete vehicles, loose body parts, or any metal surface, significantly increasing adaptability while maintaining reliable hose guidance.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If the hose guide relies on wheel positioning for stability, then the hose can be guided, but the user's action is limited and requires constant movement of the hose away from bodywork

Engineering Contradiction:

Improvehose guidance stabilityVSAvoiduser action freedom

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The magnetic attachment system replaces the wheel-dependent mechanical wedge system, allowing the hose guide to be positioned independently of wheel locations. This provides users with freedom to position the guide optimally for each painting task without being constrained by wheel positions, while maintaining stable hose guidance.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
