Solution Overview

Problem

Existing vehicle splash guards fail to securely attach to vehicle body panels, leading to potential detachment and reduced effectiveness in deflecting debris, which can cause damage to the vehicle and external objects.

Innovation Solution

A vehicle splash guard design featuring a flexible body with integrated positioning tabs that securely attach to the vehicle body panel component, providing a fixed and flexible attachment system to prevent flutter and ensure effective debris deflection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the splash guard is made of flexible material to maintain durability and aerodynamic performance, then the flexibility and durability are improved, but the attachment security to the vehicle body panel deteriorates

Engineering Contradiction:
Improveattachment securityVSAvoidattachment structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The attachment structure is segmented into distinct components: positioning tabs for alignment and engagement, and fastening elements for securing. This segmentation allows the flexible splash guard body to maintain its aerodynamic properties while the segmented attachment structure provides secure mounting to the vehicle body panel without compromising the flexibility of the main body.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the splash guard uses a simple attachment structure, then the device complexity is reduced, but the attachment security to the vehicle body panel deteriorates

Engineering Contradiction:
Improveattachment securityVSAvoidmanufacturing simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The positioning tabs and fastening elements are merged into an integrated attachment structure that is formed as one piece with the splash guard body. This merging simplifies manufacturing by eliminating separate attachment components while enhancing attachment security through the unified design that ensures proper alignment and secure engagement with the vehicle body panel.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If the splash guard is designed to be easily manufactured, then the ease of manufacture is improved, but the attachment security deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidattachment security
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The integrated attachment structure serves multiple functions simultaneously: it provides positioning alignment, secure fastening, and structural support. This multi-functionality is achieved through a single unified component design that can be easily manufactured as one piece while ensuring reliable attachment to the vehicle body panel, thus resolving the contradiction between ease of manufacture and attachment security.

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