Retractable Backup Lamp for Vintage Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vintage and antique motor vehicles often lack rear backup lighting systems, which are essential for safety but require modifications that compromise the vehicle's authenticity when fixed immobile systems are installed, as they need to be integrated into the existing structure without altering its appearance.
Innovation Solution
A retractable hidden backup lamp system that uses a linear actuator and electronic relays to rotate the lamp from a hidden position to a visible position when the vehicle is in reverse gear, utilizing existing mounting areas and maintaining the vehicle's visual integrity by being concealed when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed immobile back-up lighting is installed on a vintage motor vehicle, then back-up illumination safety is improved, but the vehicle body authenticity is compromised due to required modifications
Solution Approach 1:
The back-up lamp is designed to be movable rather than fixed, rotating between a hidden position (maintaining vehicle authenticity) and a visible position (providing back-up illumination). The lamp assembly includes a rotation mechanism that allows it to be positioned out of view during normal operation and rotated into view when reverse lighting is activated, thus resolving the contradiction between safety functionality and aesthetic preservation.
2Shape
If a retractable hidden back-up lighting system is installed, then vehicle authenticity is maintained, but the device complexity increases due to additional mechanical components
Solution Approach 1:
The rotation mechanism and lamp housing are merged into a single integrated assembly that rotates as one unit. The actuator is mounted on the vehicle body while the lamp assembly rotates on a pivot point, combining multiple functions (mounting, rotation, positioning) into a compact mechanism that minimizes the number of separate components and simplifies installation.
3Ease of manufacture
If modifications are made to integrate back-up lighting into existing structure, then installation ease is improved, but the vehicle structure is altered
Solution Approach 1:
The back-up lamp assembly is designed as a separate, extractable unit that mounts to the vehicle body through existing holes or mounting areas without requiring permanent modifications to the vehicle structure. The actuator and lamp components can be installed independently and removed if needed, preserving the original vehicle structure while providing the desired functionality.

AI summary
A rear hidden lighting system for an automobile is comprised of a lamp mounted to a bracket attached to the vehicle's rear structure, a linear actuator mounted to the vehicle's structure which rotates the lamp, an electronic relay system which powers the linear actuator in two directions, a switch mounted to the transmission of the vehicle which provides switched power to the linear actuator. When the vehicle is placed in reverse gear, the lamp will rotate out of a hidden position becoming visible and lighting the rear of the vehicle. The lamp will rotate back to the hidden position when the vehicle is taken out of reverse gear. An objective and benefit is that the lamp and bracket and the linear actuator can be mounted to existing attachment points on the vehicle which will not necessitate drilling holes, altering vehicle componentry or welding parts to existing vehicle parts or structure.
