Single-Track Vehicle State Display With Indirect Light Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-track vehicles, lacking a closable passenger compartment, face challenges in visually conveying vehicle information without unreasonably influencing road users, as existing display methods are not designed to prevent direct visual impact.
Innovation Solution
A vehicle state display system featuring a projection surface, a cover, and an illuminant coupled to a controller, which generates different light images representing vehicle states indirectly, preventing direct light perception from outside the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual display means are used to convey vehicle information, then information comprehension is improved, but road users are unreasonably influenced
Solution Approach 1:
The patent introduces a projection surface as an intermediary between the illuminant and the external environment. The light from the illuminant projects onto this surface, creating visible vehicle state information without exposing the direct light source to road users. This mediator allows information transmission while filtering out the harmful direct visual influence.
Solution Approach 2:
The patent transitions the display from a direct two-dimensional light source to a projected image on a surface, effectively using the third dimension (space) to separate the illuminant from the viewing area. The projection surface can be positioned in a gap of the outer skin at a distance from the display, creating spatial separation that reduces direct visual impact while maintaining information visibility.
2Illumination intensity
If direct light emission is used for display, then information visibility is improved, but distraction to road users increases
Solution Approach 1:
The projection surface acts as a mediator that converts direct light emission into indirect light projection. The illuminant emits light that is then projected onto the surface, creating visible information without exposing road users to direct light sources. This resolves the contradiction by maintaining visibility through the projected image while eliminating the distracting direct light.
Solution Approach 2:
Instead of directly emitting light toward road users, the system creates a copy or projection of the light pattern on a separate surface. The projection surface displays the vehicle state information as a projected image, which is visible to road users without requiring direct line-of-sight to the illuminant, thereby reducing distraction while maintaining information visibility.
3Loss of information
If illuminant is positioned for direct visibility, then information transmission is improved, but safety compliance deteriorates
Solution Approach 1:
The patent uses spatial positioning in three dimensions to resolve the safety compliance issue. The projection surface is positioned in a gap of the outer skin at a distance from the illuminant, creating a spatial separation that ensures road users cannot directly see the illuminant while still being able to view the projected information. This dimensional approach maintains information transmission while achieving safety standard compliance.
Solution Approach 2:
The projection surface serves as an intermediary that decouples the illuminant position from the information display position. The illuminant can be positioned optimally for illumination without being directly visible, while the projection surface displays the information in a location that complies with safety standards. This mediator enables both effective information transmission and regulatory compliance.

AI summary
A single-track vehicle has a vehicle state display and a controller. The vehicle state display includes at least one projection surface, a cover, and at least one lighting device. The at least one lighting device is coupled to the controller, and the at least one lighting device and the cover are arranged such that light emitted from the lighting device can only be perceived indirectly from outside of the vehicle. The lighting device is designed to generate at least one first light pattern corresponding to a first vehicle state and a second light pattern corresponding to a second vehicle state on the projection surface on the basis of control signals of the controller. The first light pattern and the second light pattern are different.
