Solution Overview

Problem

Existing air guiding devices for motor vehicles lack the flexibility to adapt to varying requirements and circumstances, as they do not allow independent adjustment of the angle of attack and deployment height, leading to suboptimal aerodynamics and appearance.

Innovation Solution

A fixture combining a linear adjustment device and an angle adjustment device, actuated independently, with a spindle actuator and kinematic mechanism for precise and robust adjustability, featuring a central drive unit and double mounting for robustness and precision, allowing infinite variable lockability and conversion of linear movement to tilting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If air guiding device position is fixed, then manufacturing and installation are simple, but adaptability to different requirements and circumstances is poor

Engineering Contradiction:
ImproveadaptabilityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by transforming the fixed air guiding device into an adjustable one. Two independent adjustment devices are introduced: a linear adjustment device for deployment height and an angle adjustment device for angle of attack. This allows the device to adapt to different requirements and circumstances while maintaining a relatively simple overall structure through modular adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If only linear deployment adjustment is provided, then structure is simple, but aerodynamic optimization is limited

Engineering Contradiction:
Improveaerodynamic precisionVSAvoidstructure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The adjustment system is segmented into two independent functional modules: linear adjustment device for deployment height control and angle adjustment device for angle of attack control. This segmentation allows precise aerodynamic optimization through independent adjustment of each parameter while keeping each module's structure relatively simple and manageable.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If adjustment devices are interconnected, then synchronization is achieved, but independent adjustment capability is lost

Engineering Contradiction:
Improveindependent adjustmentVSAvoidsynchronization
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The adjustment system is divided into two independently controllable modules: linear adjustment device and angle adjustment device. Each module can operate independently to adjust deployment height or angle of attack as needed. The segments are connected to the air guiding device but not to each other, preserving independent adjustment capability while maintaining system reliability through straightforward mechanical connections.

Inventive Principle:
Principle #1Segmentation
