Vehicle Air Baffle Assembly With Lever-Mounted Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing front face assemblies of vehicles equipped with lighting devices face challenges of requiring large space for housing the lighting device and limiting the flexibility of the lighting device's movement due to its securement to the shut-off element.
Innovation Solution
A front face lighting assembly with a screen and a shut-off device comprising flaps controlled by a lever, where the lighting device is distinct from the flaps and secured to the lever, allowing independent movement and configuration changes relative to the air flow passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lighting device is secured to the shut-off element (flap), then the lighting device moves with the flap to maintain positioning, but the flexibility of movement of the lighting device within the front face assembly is limited
Solution Approach 1:
The patent separates the lighting device from the shut-off element, making them independent components. The lighting device is borne by the lever structure rather than being secured to the flap, allowing the lighting device to move independently from the shut-off element while maintaining its positioning function.
Solution Approach 2:
The lighting device is designed to be movable relative to the shut-off element through the lever mechanism. The lever can translate to move the lighting device between configurations (facing the passage or moved away), providing dynamic adaptability while the shut-off element performs its sealing function independently.
2Adaptability or versatility
If a lighting device is associated with a front face assembly, then the assembly provides both air flow control and lighting functions, but a large space is required for housing the lighting device
Solution Approach 1:
The patent combines the lighting device with the lever structure that controls the shut-off element. By integrating the lighting device into the existing lever mechanism rather than adding a separate housing, the patent achieves multi-functionality (air flow control + lighting) without requiring additional space beyond what is already needed for the lever operation.
Solution Approach 2:
The lever structure serves dual purposes: it controls the shut-off element for air flow regulation and simultaneously bears the lighting device. This universal use of the lever mechanism allows the front face assembly to perform multiple functions (shut-off control and lighting) within the same structural envelope, avoiding increased volume.
3Adaptability or versatility
If the lighting device is secured to the lever and distinct from the flap, then the flexibility of movement is improved, but the complexity of the assembly increases
Solution Approach 1:
The patent merges the lighting device mounting function into the existing lever structure. Rather than creating a separate mounting mechanism, the lever itself serves as the bearing structure for the lighting device, thereby providing independent movement capability without adding separate complex assembly components.

AI summary
A baffle assembly includes a screen defining at least one air flow passage through the screen, a shut-off device having at least one flap configured to move between at least two positions to control circulation of the air flow through the passage, a lever controlling the positions of the flap, and at least one lighting device borne by the lever and distinct from the flap.
