Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling vehicle headlights to project images onto a surface are cumbersome, requiring complex mechanical connections and hardware setups for data transmission, which reduces user comfort and operational convenience.
Innovation Solution
Utilizing a portable data communication device, such as a smartphone or tablet, to transmit image data to a motor vehicle's image processing device, which generates control signals for a high-resolution headlight with individually controllable pixels, eliminating the need for mechanical connections and allowing for wireless image data transfer via wired or wireless networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a data carrier is connected to the vehicle to transmit image data, then image data can be transmitted to the headlight, but the connection becomes awkward and complex, reducing user-friendliness
Solution Approach 1:
The headlight system is enhanced with an image projection function in addition to its primary illumination function. The same headlight hardware can switch between projecting images onto surfaces and providing standard headlight illumination, eliminating the need for separate dedicated projection hardware and reducing overall system complexity.
Solution Approach 2:
The image projection capability is extracted as a separate controllable function from the main headlight system. By using an optical unit with controllable light distribution, the system can selectively project images while maintaining normal illumination capabilities, allowing independent operation of each function.
2Adaptability or versatility
If the headlight is used as a projector for image data when the vehicle is stationary, then images can be displayed on a projection surface, but the complexity of data transmission increases significantly
Solution Approach 1:
The headlight system serves multiple functions: standard illumination and image projection. The control unit manages both functions, and the optical unit can dynamically adjust light distribution between these modes, reducing the need for separate dedicated hardware systems.
Solution Approach 2:
The control unit acts as an intermediary between the image data source and the headlight pixels. It processes image data and generates appropriate control signals for the optical unit, simplifying the overall data transmission architecture by centralizing control logic.
3Manufacturing precision
If multiple controllable headlight pixels are used to generate images, then high-resolution image display is achieved, but the control system complexity increases
Solution Approach 1:
Each headlight pixel or group of pixels functions as an independently controllable element that can be directly addressed by the control unit. This self-service approach allows precise control of individual pixels to form high-resolution images without requiring complex mechanical positioning or additional intermediary components.
Solution Approach 2:
The headlight optical system is divided into multiple individually controllable pixel elements. By segmenting the light source or optical modulation into discrete controllable units, the system can generate high-resolution images through digital control of each segment, replacing analog optical mechanisms.
