Innovation Solution
A system within a vehicle that includes a perception system to detect individuals, a monitoring system to track head and eye positions, a holographic image generator to calculate and encode images, and a beam steering device to project images directly to the eyes, along with an audio communication system for audible interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If inverse head-up-display architectures with beams splitters are used, then visual information can be displayed to passengers, but the system requires constant re-adjustment to accommodate height and position variations
Solution Approach 1:
The patent replaces the mechanical beams splitter attachment system with a digital/light-based solution using display devices (such as head-up displays or augmented reality displays) that can dynamically adjust their optical paths through electronic control of light reflection and refraction, eliminating the need for physical re-adjustment mechanisms
Solution Approach 2:
The system implements dynamic adjustment capabilities where display devices can automatically adapt to different passenger positions and heights through real-time detection and computational adjustment of the displayed image parameters, allowing the system to remain optimal without manual re-adjustment
2Adaptability or versatility
If external screens are used for displaying to persons outside the vehicle, then communication with external individuals is enabled, but the system lacks directional precision for individual targeting
Solution Approach 1:
The patent applies local quality by directing visual and audio information to specific locations in space where individual persons are positioned, rather than using a general external screen. The system calculates and projects images to precise coordinates corresponding to each person's location, enabling targeted communication with external individuals
Solution Approach 2:
The system introduces computational algorithms and beam steering devices as intermediaries between the vehicle's communication system and external persons. These intermediaries calculate the precise projection parameters and physically direct the light beams to the correct external locations, achieving both external communication capability and directional precision
3Adaptability or versatility
If traditional audio systems are used, then audio can be played inside the vehicle, but the system lacks directional audio output to specific individuals outside the vehicle
Solution Approach 1:
The patent implements local quality in the audio system by directing sound waves to specific locations in space where individual persons are positioned. The audio system calculates the precise location of each person and projects sound beams to those specific coordinates, enabling targeted audio communication with external individuals rather than omnidirectional sound distribution
