Rotatable Vehicle Illumination Bracket for Dynamic Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle illumination systems are fixed and cannot adjust their illumination area dynamically, limiting their effectiveness in providing adequate lighting in varying environments and user needs.
Innovation Solution
A rotatable illumination system connected to the movable closure of a vehicle, allowing the illumination area to adjust based on the position of the closure, with a controller activating the light source under specific vehicle conditions such as opening of the closure, low speed, and low ambient light, and featuring a universal joint and independent power source for enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed illumination device is installed on the trunk, then the structure is simple and easy to manufacture, but the illumination area cannot be adjusted to meet varying user needs
Solution Approach 1:
The illumination device is mounted on a bracket that can rotate relative to the trunk lid, transforming the fixed illumination system into a dynamic one. The bracket includes a rotating mechanism with a pivot pin, allowing the light source to change its illumination direction and area according to different trunk opening angles and user needs, while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the illumination device is fixed on the trunk lid, then the installation is simple, but the illumination area remains fixed and cannot adapt to different environments
Solution Approach 1:
The illumination device incorporates a rotatable bracket mechanism that allows dynamic adjustment of the light beam direction. This enables the system to adapt to different environmental conditions (dark environments, different trunk opening angles) while maintaining ease of operation through automatic activation controlled by a control unit that detects trunk opening status.
Solution Approach 2:
The system changes the illumination parameters (illumination area, light direction) by rotating the bracket to different angles. The control unit adjusts the illumination state based on detected conditions such as trunk opening angle and ambient light levels, allowing the same device to provide optimal illumination for varying environmental parameters.
3Reliability
If the light source is always on, then the illumination is continuous and reliable, but the energy consumption increases
Solution Approach 1:
The illumination device operates periodically rather than continuously. The control unit activates the light source only when specific conditions are met (trunk lid is opened, ambient light is insufficient), and deactivates it when conditions change. This periodic operation ensures reliable illumination when needed while significantly reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The system incorporates a control unit that receives feedback about trunk opening status and ambient light conditions, and adjusts the illumination state accordingly. This feedback mechanism ensures the light is activated only when necessary for reliable illumination, avoiding unnecessary energy consumption while maintaining illumination reliability when the trunk is open and darkness is detected.
Data Source
AI summary
The present disclosure discloses an illumination system for a vehicle. The illumination system includes an illumination device having a light source and a bracket connected to the light source. The bracket is adapted to be rotatably connected on an inner surface of a movable closure of the vehicle, and the bracket is adjacent to a top of the vehicle when the movable closure is in an opened position.
