Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current luminous signs used in vehicle operations are static and limited to fixed positions, making it impossible to create signs in dynamic environments like in-flight refuelling or during isolated vehicle maneuvers without diverting the driver's attention.
Innovation Solution
A device that generates high-power, high-frequency laser light using a subsystem for orienting and focusing the light on specific points in space, combined with visual and analytical systems to determine target locations and communicate sign generation orders, allowing for dynamic creation of luminous signs in front of vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static luminous signs are used in fixed positions, then the signs provide stable and reliable information, but they cannot adapt to dynamic environments or moving vehicles
Solution Approach 1:
The patent applies the dynamics principle by transitioning from static luminous signs to a dynamic laser-based system that can change position and orientation in real-time. The laser device mounted on the vehicle moves with the vehicle and can dynamically adjust the position of luminous signs in space according to the vehicle's movement and operational requirements, resolving the contradiction between adaptability and stability.
Solution Approach 2:
The patent utilizes parameter changes by varying the spatial coordinates (x, y, z) where laser beams create luminous points. The system can dynamically change the position, intensity, and distribution of luminous signs in three-dimensional space, allowing adaptation to different operational scenarios while maintaining reliable visual information for drivers.
2Adaptability or versatility
If static luminous panels are used, then the signs can notify of different actions or content, but they remain limited to relatively precise spatial locations
Solution Approach 1:
The patent applies dimensionality change by creating luminous signs in three-dimensional space rather than limiting them to two-dimensional panels. The laser system can project luminous points at various heights, distances, and lateral positions, expanding the spatial coverage area from a fixed panel location to a volumetric space around the vehicle, thereby increasing both flexibility and spatial coverage.
3Adaptability or versatility
If high-power lasers are used to create luminous signs in space, then dynamic and flexible signs can be created, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the laser control system into independent modules: laser beam generation, galvanometric mirror orientation control, and focal point coordinate calculation. Each module operates semi-independently, allowing the complex function of creating dynamic luminous signs to be achieved through coordinated simple actions of separate components, thereby managing device complexity.
4Ease of operation
If luminous signs are created directly in front of the vehicle, then the driver can see them within their field of vision, but the system requires precise positioning and control
Solution Approach 1:
The patent replaces complex mechanical positioning systems with an optical-mathematical approach. Instead of physically moving heavy sign structures to precise locations, the system uses laser beams directed by galvanometric mirrors, whose position is controlled through electrical signals and mathematical calculations of coordinates. This substitution reduces mechanical complexity while achieving precise positioning required for driver visibility.

AI summary
The present invention details a group of focussed means to create points of light of different sizes and colours, that together form figures whose function is to create a sign in front of the eyes of a driver or operator, to provide them with certain information from a remote point. The points of light are created by the ionization of the air in different points in the space where it is desirable to create the sign in question.
