Redundant Backup Lamps for Tailgate Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle exterior lighting systems lack redundancy in backup lighting functionality when the tailgate is in closed, open, or removed positions, as existing systems rely on a single backup lamp configuration that may not provide consistent illumination across all positions.
Innovation Solution
Incorporating both vehicle static body structure-mounted backup lamps and tailgate structure-mounted backup lamps, with an illumination control module that activates these lamps in response to gear shifts and tailgate positions to ensure redundant backup lighting, including zone lighting effects when the tailgate is open.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single backup lamp configuration is used, then device complexity is reduced, but reliability of backup lighting across all tailgate positions deteriorates
Solution Approach 1:
The backup lighting system is segmented into two independent lamp configurations: a first backup lamp mounted to the vehicle static body structure and a second backup lamp mounted to the tailgate assembly. This segmentation allows each lamp to independently provide backup lighting, ensuring reliability across all tailgate positions (closed, open, or removed) while maintaining manageable system complexity through modular design.
2Reliability
If both static body structure-mounted and tailgate-mounted backup lamps are incorporated, then reliability of backup lighting is improved, but device complexity increases
Solution Approach 1:
The illumination control module is designed with multi-functionality to universally control both the first backup lamp (static body structure-mounted) and the second backup lamp (tailgate-mounted). The control module responds to gear shift signals and tailgate position signals to activate the appropriate lamp or both lamps simultaneously, providing redundant backup lighting across all operating conditions while managing system complexity through integrated control logic.
3Adaptability or versatility
If the second backup lamp is part of an illuminating light bar module on the tailgate, then adaptability to different tailgate positions is improved, but device complexity increases
Solution Approach 1:
The second backup lamp is merged with the illuminating light bar module that is mounted to the tailgate structure. This combination allows the backup lighting function to be integrated with the existing light bar assembly, providing adaptability to different tailgate positions (closed, open, or removed) while reducing overall device complexity by consolidating multiple lighting functions into a single modular unit.

AI summary
Vehicle exterior lighting systems for vehicles equipped with tailgate assemblies may be configured to provide redundant backup lighting functionality for all tailgate positions (e.g., closed, open, and removed). Exemplary systems may include both vehicle static body structure mounted backup lamps and tailgate structure mounted backup lamps for providing the backup lighting redundancy.
