Vehicle Puddle Lamp Assembly Generating Moving Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle puddle lamps primarily provide static illumination, lacking the ability to generate animated images that could enhance visibility and aesthetics for users approaching or exiting the vehicle.
Innovation Solution
A vehicle puddle lamp assembly featuring a plurality of light projectors and a controller that sequentially activates these projectors to create moving animated lighted images on the ground surface adjacent to the vehicle, triggered by the door's open position, using sensors to manage activation and intensity based on user proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light projectors are used to generate animated images, then the illumination effectiveness and aesthetics are improved, but the device complexity increases
Solution Approach 1:
The puddle lamp system is divided into multiple independent light projectors, each capable of projecting a specific portion of the animated image. This segmentation allows the system to create complex animated illumination patterns by coordinating multiple simpler projector units, thereby improving overall illumination effectiveness while managing device complexity through modular design
Solution Approach 2:
The light projectors are configured to dynamically change their illumination patterns by sequentially activating different projectors or adjusting their brightness levels. This dynamic operation transforms static puddle lamps into animated image generators, enhancing both illumination effectiveness and aesthetic appeal without requiring permanent complex structural changes
2Illumination intensity
If sequential activation of light projectors is implemented, then a moving animated image is generated, but the control system complexity increases
Solution Approach 1:
The control system activates light projectors in a periodic sequential manner, turning each projector on and off in a predetermined sequence to create the illusion of moving animated images. This periodic activation pattern simplifies control logic compared to continuous complex modulation, as each projector follows a repeating on-off cycle that can be easily programmed and executed
Solution Approach 2:
The control system is designed to automatically manage the sequential activation of light projectors based on simple trigger signals (such as door opening detection). Once initiated, the system self-regulates the timing and sequence of projector activation without requiring continuous external control input, thereby reducing operational complexity while maintaining animated image generation capability
