Solution Overview

Problem

Existing mudflaps on vehicles are not easily cleanable, leading to dirt accumulation that increases fuel consumption and can damage vehicle parts, and current cleaning methods using pressurized water are inefficient and environmentally unfriendly.

Innovation Solution

A mudflap design featuring a base layer with protrusions and an exposed layer with orifices, allowing for easy detachment and reattachment using Velcro elements, enabling efficient dirt removal by moving the exposed layer from an operation position to a cleaning position, which reduces dirt accumulation and facilitates economical cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If pressurized water is used to clean mudflaps, then cleaning effectiveness is improved, but water consumption increases and environmental friendliness deteriorates

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidwater consumption
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The mudflap structure enables self-cleaning through its own movement. The exposed layer with protrusions automatically sheds dirt when the mudflap moves between operation and cleaning positions, eliminating the need for external water resources while maintaining cleaning effectiveness

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mudflap is divided into a base layer and an exposed layer that can move relative to each other. This segmentation allows the exposed layer to be detached and repositioned, creating a self-cleaning mechanism that removes dirt without requiring water

Inventive Principle:
Principle #1Segmentation

2Productivity

If pressurized water is used to clean mudflaps, then dirt removal is improved, but cleaning accessibility deteriorates due to requirement of dedicated areas

Engineering Contradiction:
Improvedirt removal efficiencyVSAvoidcleaning accessibility
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The mudflap performs its own cleaning function through mechanical movement of the exposed layer between operation and cleaning positions. This self-service capability eliminates the need for dedicated cleaning areas or specialized equipment, making cleaning accessible anywhere the vehicle operates

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The exposed layer is designed to be movable relative to the base layer, transitioning between operation and cleaning positions. This dynamic structure enables the cleaning function to be performed in various locations without requiring fixed infrastructure

Inventive Principle:
Principle #15Dynamics

3Use of energy by moving object

If dirt accumulates on mudflaps, then weight increases leading to higher fuel consumption, but cleaning frequency increases operational complexity

Engineering Contradiction:
Improvefuel consumptionVSAvoidcleaning operational complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The mudflap automatically reduces dirt accumulation through movement of the exposed layer, which sheds dirt during normal operation and cleaning position transitions. This self-service mechanism prevents excessive weight gain and reduces fuel consumption without requiring complex cleaning schedules or procedures

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The exposed layer periodically transitions between operation and cleaning positions, creating regular intervals for dirt removal. This periodic action prevents excessive dirt accumulation and maintains optimal weight, reducing fuel consumption through simple periodic movement rather than complex continuous cleaning systems

Inventive Principle:
Principle #19Periodic action
