Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle projection systems are limited in their ability to display visually sensible patterns externally, particularly in a way that is synchronized across multiple vehicles, and lack integration with vehicle operational states for dynamic content display.
Innovation Solution
A vehicle projection system that includes a projector, a media memory device, and a display control subsystem responsive to vehicle operational states, using various projection configurations and synchronization mechanisms to display visually sensible patterns on vehicle surfaces, such as windshields, and synchronizing these displays across multiple vehicles for enhanced visibility and relevance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If projection systems are installed in multiple vehicles for synchronized display, then the advertising or informational impact is amplified, but the system complexity and synchronization coordination become more difficult
Solution Approach 1:
The patent combines multiple vehicle projection systems into a coordinated network where projectors in different vehicles work together to display unified or complementary visual content. The control subsystems are merged through communication protocols that allow centralized or distributed synchronization, transforming individual isolated systems into an integrated multi-vehicle display network that amplifies advertising impact while managing complexity through standardized interfaces.
Solution Approach 2:
The projection system is designed with universal control capabilities that can operate in multiple modes: individual vehicle display, synchronized multi-vehicle display, and adaptive content delivery based on vehicle location and context. The control subsystem can function as both a standalone unit and a networked node, providing multi-functionality that handles various display scenarios without requiring separate specialized systems for each mode.
2Illumination intensity
If windshields are transformed into semi-opaque or emissive screens for external projection, then visibility of projected patterns is enhanced, but the optical properties and material composition of windshields must be modified
Solution Approach 1:
Rather than modifying the entire windshield uniformly, the system applies projection-specific optical treatments to specific zones or regions of the windshield where projection occurs. This localized approach allows the majority of the windshield to maintain its original transparent, easy-to-manufacture properties while only the projection display areas receive specialized semi-opaque or emissive coatings, balancing visibility enhancement with manufacturing ease.
Solution Approach 2:
The system dynamically adjusts the optical parameters of the windshield surface through controllable projection modes. The windshield can switch between transparent, semi-opaque, and emissive states based on projection requirements, using electrochromic or similar controllable materials that change their optical properties on demand rather than requiring permanent structural modification.
3Adaptability or versatility
If projection systems are integrated with vehicle operational states, then dynamic content display becomes possible, but the system requires additional sensors and control integration
Solution Approach 1:
The control subsystem is designed to receive and process vehicle operational data in advance of projection needs. By continuously monitoring vehicle state parameters (speed, location, operational mode) and pre-processing this information, the system prepares appropriate projection content and timing ahead of actual display requirements, reducing real-time computational complexity and enabling dynamic content adaptation without overwhelming the control system.
Solution Approach 2:
The system implements feedback loops where projection output and vehicle state information are continuously monitored and used to adjust subsequent projection content. The control subsystem receives feedback from both the projection system performance and vehicle operational sensors, automatically adjusting display parameters, content selection, and synchronization timing to optimize the projection effect while maintaining integration with vehicle operations.
