Segmented Front Spoiler Lip with Depression Beads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing front spoiler arrangements require high actuating forces to adjust spoiler lip areas, limiting flexibility and increasing complexity, while also lacking desirable design separation between areas.
Innovation Solution
The introduction of depressions or beads on the spoiler lip, extending to its outer edge, separates individual spoiler areas, reducing actuating force and allowing for independent adjustment of spoiler areas, with optional geometric shapes and actuator valve arrangements for optimized air resistance and fuel efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the spoiler lip is divided into multiple adjustable spoiler areas, then the flexibility and adaptability of the front spoiler arrangement is improved, but the actuating force required to adjust the spoiler areas increases significantly
Solution Approach 1:
The spoiler lip is segmented into multiple independently adjustable spoiler areas (first, second, and third spoiler areas) separated by depressions. This segmentation allows each area to be adjusted independently to different positions, providing flexibility and adaptability for different driving conditions while reducing the actuating force required compared to adjusting a single large spoiler area as one unit.
2Force
If the spoiler areas are separated by depressions, then the actuating force is reduced and design flexibility is improved, but the structural complexity of the spoiler lip increases
Solution Approach 1:
The spoiler lip incorporates depressions (bead structures) that create flexible transition zones between adjacent spoiler areas. These depressions allow the spoiler lip to bend and flex more easily, reducing the actuating force required to adjust individual spoiler areas. The depressions are integrated into the spoiler lip structure itself, adding minimal complexity while providing significant force reduction.
3Loss of energy
If multiple spoiler areas are adjusted independently, then the air resistance optimization is improved, but the device complexity and cost increase
Solution Approach 1:
The spoiler lip is divided into multiple independently adjustable spoiler areas (first, second, and third spoiler areas) separated by depressions. This segmentation allows each area to be adjusted independently to different positions, providing flexibility and adaptability for different driving conditions while reducing the actuating force required compared to adjusting a single large spoiler area as one unit.
Solution Approach 2:
The actuator device is designed with a valve arrangement that can control multiple spoiler areas using a single actuator mechanism. This multi-functional design allows one actuator to adjust different spoiler areas independently or together, optimizing air resistance for various driving modes (economy mode with outer areas extended, performance mode with middle area extended) without requiring separate actuators for each spoiler area, thereby controlling device complexity and cost.

AI summary
Front spoiler arrangement for a motor vehicle with a spoiler lip (6) extending at least partially in the transverse direction of the motor vehicle in the front area of the motor vehicle, having at least two spoiler areas (8, 10, 12) which can be moved separately or together from a retracted rest position to an extended spoiler position by at least one actuator device, wherein the individual spoiler areas (8, 10, 12) are separated from each other on a front side (18) of the spoiler lip (6) by at least one recessed shape (14, 16) extending into an outer edge (20) of the spoiler lip facing away from the front part (2).
