Air Flap Actuator Layout for Central Radar Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a radar sensor in the center of a vehicle is not possible due to space constraints, as both the actuator of the air flap system and the radar sensor require a significant amount of construction space.
Innovation Solution
An air flap system with an eccentrically arranged actuator, allowing for a central placement of the radar sensor by optimizing the use of construction space and reducing the vehicle's longitudinal and transverse dimensions.

Engineering Contradiction Analysis
1Volume of moving object
If the actuator is arranged centrally in the air flap system, then the radar sensor cannot be integrated in a central position due to space constraints, but if the actuator is arranged eccentrically, then the radar sensor can be placed centrally while maintaining efficient space utilization
Solution Approach 1:
The actuator is arranged eccentrically (asymmetrically) within the air flap system rather than at the center, creating an asymmetric layout that frees up the central position for the radar sensor. This asymmetric arrangement allows both components to be integrated efficiently without spatial conflict, resolving the contradiction between space utilization and sensor integration.
2Length of stationary object
If the air flap system is designed with rigid fastening in the vehicle frame, then the construction space is reduced, but the integration of radar sensor in central position becomes impossible due to space requirements of both actuator and sensor
Solution Approach 1:
By positioning the actuator asymmetrically (eccentrically) within the air flap system, the design creates available central space that maintains compact vehicle dimensions while providing the flexibility needed for central radar sensor integration. The asymmetric actuator placement adapts the space distribution to accommodate both the actuator and radar sensor optimally.
Solution Approach 2:
The air flap system is segmented into distinct functional zones with the actuator occupying a specific eccentric position, separating its space requirements from the central region. This segmentation allows the radar sensor to be integrated in the central position without conflicting with the actuator, maintaining both compact dimensions and sensor placement flexibility.
3Volume of moving object
If the actuator occupies central space in the air flap system, then the available construction space is maximized for the actuator, but the radar sensor integration is prevented, whereas eccentric actuator arrangement enables both compact dimensions and central sensor placement
Solution Approach 1:
The eccentric (asymmetric) arrangement of the actuator within the air flap system optimizes space allocation by positioning the actuator in a non-central location. This asymmetric placement ensures adequate space for the actuator while simultaneously enabling central integration of the radar sensor, achieving efficient space utilization without excessive spatial arrangement complexity.

AI summary
An air flap system for controlling air ingress into a motor vehicle has at least one air flap, which can be pivoted between an open position and a closed position, and an actuator, which is coupled to the air flap, such that the actuator is suitable for effecting the pivoting of the air flap. The actuator is arranged off-center in a central region with respect to one extent of the air flap system along a transverse axis of the vehicle. The central region is one of at least three regions which are arranged adjoining one another along the extent, the central region being arranged centrally with respect to the extent.
