Vehicle Front Grille Lighting Assembly with Independent Shutter Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing front-end assemblies in vehicles require substantial space for integrated lighting devices and limit the flexibility of lighting due to their fixed attachment to shutter elements, compromising airflow control and vehicle efficiency.
Innovation Solution
A front-facing lighting assembly with a grille and shuttering device where the lighting device is separate from the shutter, allowing independent movement and configuration changes via a lever system, reducing space requirements and enhancing airtightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lighting device is fixed to the shutter element, then the lighting device is integrated into the front-end assembly, but the flexibility of movement within the assembly is limited
Solution Approach 1:
The lighting device is separated from the shutter element into two independent components. The shutter element remains part of the airflow control system while the lighting device is mounted separately on the front-end assembly, allowing each component to function independently without movement constraints
Solution Approach 2:
The lighting device is extracted from its traditional fixed attachment to the shutter element and repositioned as a separate component. This extraction allows the lighting device to be positioned optimally for illumination while the shutter element maintains its airflow control functionality without being constrained by lighting requirements
2Illumination intensity
If a substantial amount of space is allocated for the lighting device, then the lighting device can be properly integrated, but the space available for airflow control is reduced
Solution Approach 1:
The lighting device is positioned in a different spatial dimension or location within the front-end assembly, separate from the airflow control pathways. This allows the lighting device to occupy space that does not interfere with airflow channels, maintaining both adequate lighting functionality and sufficient space for effective airflow control
3Productivity
If the shutter element blocks the passage, then airflow control is improved, but the lighting device cannot be positioned directly opposite the passage
Solution Approach 1:
The shutter element and lighting device are segmented as separate components with independent positioning capabilities. The shutter element can block the airflow passage to control air penetration coefficient without constraining the lighting device's position, allowing the lighting device to remain directly opposite the passage for optimal light beam visibility through the grille
Solution Approach 2:
The independent positioning of the lighting device allows it to maintain a static optimal position opposite the passage while the shutter element dynamically adjusts to block or open the passage as needed for airflow control, ensuring both functions operate at peak efficiency
