Solution Overview

Problem

Existing air guiding devices for motor vehicle bodies suffer from deformation due to assembly and operational forces, compromising their dimensional stability and structural integrity.

Innovation Solution

Incorporating a support element along the rotational axis of the slat assembly to stabilize the frame, using snap-fit connections for cost-effective assembly, and ensuring the slats are vertically arranged to resist deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the slat assembly is made movable and adjustable, then the air flow control capability is improved, but the structural stability and resistance to deformation worsen

Engineering Contradiction:

Improveair flow control capabilityVSAvoidstructural stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The slat assembly is divided into multiple individual slats that can move independently within the frame, allowing adjustable air flow control while maintaining overall structural integrity through the segmented design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support element is pre-installed in the frame before the slats are assembled, providing preliminary structural reinforcement that prevents deformation during subsequent assembly and operation

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If the frame is made flexible enough to allow slat rotation, then the ease of operation is improved, but the dimensional stability during assembly and operation worsens

Engineering Contradiction:

Improveslat rotation capabilityVSAvoiddimensional stability

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The frame is designed with localized flexibility at specific joints to allow slat rotation, while maintaining overall rigidity through the support element that prevents deformation in critical areas

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The support element acts as an intermediary structural component between the frame elements, mediating between the need for flexibility in slat movement and the requirement for dimensional stability during assembly and operation

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If snap-fit connections are used for assembling slats and support elements, then the ease of manufacture is improved, but the strength and reliability of connections worsen

Engineering Contradiction:

Improveassembly simplicityVSAvoidconnection strength

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The support element combines multiple functions into a single component: it provides structural reinforcement, serves as a mounting platform for slats, and enables snap-fit connections, thereby achieving strong connections through integrated design

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An air guiding device of a motor vehicle body of a motor vehicle includes a slat assembly. The slat assembly possesses at least two slats which are arranged in a frame of the air guiding device in a manner which permits them to rotate around their rotational axis. To avoid deformation of the slat assembly, the slat assembly includes at least one support element, which extends along the rotational axis.
