Vehicle Courtesy Projection Control for Real-Time Custom Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle projection lamps cannot update projection content in real time and lack user customization options.
Innovation Solution
A vehicle courtesy projection system with a trigger module, control module, and projection module that allows for user-defined projection content, including video, dynamic patterns, and static patterns, controlled via a client device such as a smartphone, using technologies like LVDS, Ethernet, or CAN for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If projection lamps are used in vehicles, then illumination and visual presentation are improved, but the ability to update projection content in real time and provide user customization is lost
Solution Approach 1:
The patent applies dynamics by transitioning from static projection patterns to dynamic, real-time updatable content. The control module receives projection information from a client device and dynamically adjusts the projection content, allowing users to customize patterns, videos, and images. This enables the projection system to adapt to different user needs and scenarios while maintaining illumination functionality.
2Device complexity
If projection content is fixed and static, then device complexity is reduced, but real-time content updates and user control capabilities are limited
Solution Approach 1:
The patent introduces a control module as an intermediary between the client device (smartphone, tablet, or vehicle terminal) and the projection module. This intermediary receives projection information including content data and control instructions, processes them, and transmits to the projection module. This architecture enables user control and real-time content updates while keeping the projection hardware relatively simple and maintaining manageable system complexity.
3Adaptability or versatility
If projection content is updated in real time with user customization, then adaptability and user control are improved, but device complexity and control system requirements increase
Solution Approach 1:
The control module is designed with multi-functionality to handle various projection content types (patterns, videos, images), process different control instructions (start, pause, stop, switch), and communicate with multiple client devices. By consolidating these diverse functions into a single control module, the system achieves high adaptability and user customization capability while avoiding the need for multiple separate control systems, thus managing overall complexity.

AI summary
A vehicle courtesy projection system and a vehicle. The vehicle courtesy projection system comprises a triggering module, a first control module, and a projection module. The triggering module is connected to the first control module, and the first control module is connected to the projection module. The triggering module is configured to receive projection information sent by a client and send the projection information to the first control module. The first control module is configured to receive the projection information and control, according to the projection information, the projection module to perform projection.
