Solution Overview

Problem

Existing wheel guide rails for vehicle washing devices have complex designs and high manufacturing costs, with limited visibility due to upward-directed lighting and require complex sealing, making them difficult to manufacture and maintain.

Innovation Solution

A wheel guide rail design featuring two receiving body parts made from transparent, milky material that form a receiving space to house the lighting device, allowing light to scatter and increase visibility, with a modular structure for cost-effective production and improved operational safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If lighting elements are arranged to emit light upward only, then the lighting device structure is simple, but the visibility range is significantly limited

Engineering Contradiction:
Improvevisibility rangeVSAvoidlighting device structure
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The receiving body is made transparent or translucent, allowing the lighting elements' light to pass through and create the visual effect of the entire receiving body being illuminated. This material property change enables light to spread in multiple directions without adding complex optical components, thereby expanding visibility range while maintaining structural simplicity.

Inventive Principle:
Principle #32Color changes

2Reliability

If separate mounting bases and sealing elements are provided for each light element, then the lighting elements can be securely mounted and sealed, but the manufacturing complexity and difficulty increase significantly

Engineering Contradiction:
Improvesealing and mounting reliabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The mounting function and sealing function are merged into the receiving body itself. The recesses formed by the side walls and bottom wall of the receiving body serve as both mounting locations and sealing chambers for the lighting elements, eliminating the need for separate mounting bases and sealing elements. This integration significantly simplifies manufacturing while maintaining reliable mounting and sealing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The receiving body performs multiple functions simultaneously: it provides structural support, creates mounting recesses for lighting elements, provides sealing chambers, and acts as a light-diffusing element. This multi-functionality reduces the total number of components needed and simplifies the overall manufacturing process.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If a complex design with multiple components is used, then the lighting elements can be securely mounted and sealed, but the manufacturing costs become considerable

Engineering Contradiction:
Improvemounting and sealing reliabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

Multiple functions (mounting, sealing, light diffusion) are combined into a single receiving body component, reducing the total number of parts that need to be manufactured, assembled, and sealed. This consolidation reduces manufacturing complexity and cost while maintaining reliable mounting and sealing of the lighting elements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The receiving body is designed as a multi-functional component that simultaneously provides structural support, mounting recesses, sealing chambers, and light diffusion. This reduces the bill of materials and assembly operations, thereby lowering manufacturing costs while ensuring reliable operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The design enhances visibility and operational safety by creating the impression of self-luminosity, improves manufacturing efficiency, and reduces costs by allowing light to spread in multiple directions and facilitating easier assembly and maintenance.

Implementation Method 1

At least one of the receiving body parts is made in sections from a transparent, milky material. This makes it possible for the light emitted by the lighting elements to be scattered in the corresponding receiving body part and thus to spread in many directions.
