Motor Vehicle Spoiler Cover Gap Closure

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing motor vehicle spoiler arrangements fail to effectively close the rear gap between the spoiler blade and the body portion when extended, compromising optical quality and allowing foreign objects to enter.

Innovation Solution

A cover attaches to the spoiler blade, extending in the transverse and vertical directions, partially or completely closing the rear gap, and can be either a separate assembly or an integral part, enhancing the optical quality and preventing foreign bodies from entering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the spoiler blade is extended to improve aerodynamic performance, then the aerodynamic effectiveness is improved, but a rear gap is formed between the spoiler blade and body portion that compromises optical quality and allows foreign objects to enter

Engineering Contradiction:

Improveaerodynamic effectivenessVSAvoidoptical quality and foreign object intrusion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A cover element is introduced as an intermediary component between the spoiler blade and body portion. This cover attaches to the rear surface of the spoiler blade and extends downward to close the rear gap, preventing foreign objects from entering while maintaining aerodynamic effectiveness when the spoiler is in the extended position.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The spoiler arrangement is segmented into distinct functional components: the spoiler blade for aerodynamic function, the cover element for gap closure and optical quality, and the hinge arrangement for displacement control. This segmentation allows each component to optimize its specific function without compromising others.

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If a cover is added to close the rear gap and improve optical quality, then the appearance and protection are improved, but the device complexity increases

Engineering Contradiction:

Improveoptical qualityVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The cover element is merged with the spoiler blade assembly by attaching it directly to the rear surface of the spoiler blade. This integration ensures the cover moves together with the spoiler blade, maintaining gap closure effectiveness while reducing the need for separate control mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The cover element serves multiple functions simultaneously: it closes the rear gap to prevent foreign object intrusion, improves optical quality by providing a clean appearance, and potentially contributes to aerodynamic flow management. This multi-functionality reduces the need for additional components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A spoiler arrangement of a motor vehicle includes a spoiler blade, a body portion to which the spoiler blade attaches, a displacement device for the spoiler blade, the displacement device being configured to move the spoiler blade relative to the body portion between a retracted position and an extended position; and a cover configured to attach to the spoiler blade and to at least partially close a rear gap which is formed, in the extended position of the spoiler blade, between a rear edge of the spoiler blade and an adjoining assembly of the body portion.
