Vehicle Lamp Assembly with Holographic Image Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lamp assemblies on vehicles lack an effective means to notify persons proximate the vehicle of activated features, such as engine boost mode, in a visually engaging and dynamic manner.
Innovation Solution
A lamp assembly is designed with projectors, optical members, and image interferences on a holographic film, which, when activated, generate animated lighted images visible from the exterior of the vehicle, providing notification of vehicle features through sequential illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional lamp assemblies are used, then the structure is simple and cost-effective, but the ability to provide dynamic visual notifications of vehicle features is insufficient
Solution Approach 1:
The lamp assembly is divided into multiple projectors, each capable of projecting separate images onto different regions of the panel. This segmentation allows the system to display multiple different visual notifications simultaneously, enhancing adaptability while keeping each projector module relatively simple and cost-effective.
Solution Approach 2:
The system uses sequential activation of projectors to create animated lighted images that move or change over time. This dynamic capability allows the lamp assembly to provide engaging visual notifications that can indicate different vehicle features or states through motion and sequence, transforming a static system into a dynamic notification platform.
2Loss of information
If multiple projectors are used to create animated images, then the visual notification effectiveness is improved, but the device complexity and cost increase
Solution Approach 1:
Multiple projectors are merged into a coordinated system that projects images onto a shared panel with holographic film. By combining the projectors' output on a common surface and using sequential activation, the system creates the illusion of complex animated displays while actually using relatively simple individual projector components, reducing overall system complexity.
Solution Approach 2:
The system uses holographic film or image interferences on the panel to create visual copies or representations of the projected light patterns. This allows the actual projector mechanisms to remain simple while the perceived visual output appears complex and informative, effectively reducing the complexity-to-information-ratio of the system.
3Adaptability or versatility
If sequential activation of projectors is used, then animated visual notifications are achieved, but the energy consumption increases
Solution Approach 1:
The projectors are activated in sequential periods rather than continuously, with each projector turning on and off in a controlled sequence to create the animated effect. This periodic activation significantly reduces energy consumption compared to continuous operation, while still achieving the desired animated visual notifications through timing and sequencing.
Solution Approach 2:
The system uses dynamic sequential activation where only the necessary number of projectors are active at any given moment. By controlling the timing and duration of each projector's operation, the system achieves animated visual effects with minimal energy expenditure, as opposed to having all projectors running simultaneously or continuously.
