Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting modules for motor vehicles cannot dynamically adapt symbols on the ground to reflect the current traffic situation, failing to provide timely and relevant information to drivers and other road users about potential collisions.
Innovation Solution
A motor vehicle equipped with a projection lighting module and a control device that predicts the movement of road users using environmental sensors and communication interfaces, allowing the symbols on the ground to be dynamically modified in size, orientation, position, shape, brightness, and color to convey warning signals and intended vehicle movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static images are generated by the lighting module, then the structure is simple and easy to implement, but the symbols cannot be dynamically adapted to the current traffic situation
Solution Approach 1:
The patent applies dynamics by transitioning from static projected symbols to dynamically adjustable symbols that change based on predicted road user movements. The control device modifies symbol parameters (position, size, shape, brightness, color) in real-time based on sensor data and movement predictions, making the lighting system adaptive to changing traffic situations.
Solution Approach 2:
The patent implements preliminary action by predicting future positions of road users before collisions occur. The control device uses sensor information to forecast movement trajectories and pre-adapts the symbol configuration to warn road users about impending hazards, enabling early intervention rather than reactive response.
2Reliability
If the set of symbols is modified based on predicted movement, then early warning of collisions is achieved, but more sensors and processing power are required
Solution Approach 1:
The patent implements feedback by continuously monitoring road user positions through sensors, predicting their movement trajectories, and using this information to dynamically adjust the projected symbols. The control device creates a closed-loop system where sensor input feeds into movement prediction algorithms, which then drive symbol modification to provide accurate safety warnings.
Solution Approach 2:
The system applies self-service by using the motor vehicle's existing sensor infrastructure (cameras, lidars, radars) and processing capabilities to autonomously predict road user movements and adapt the lighting symbols without requiring external intervention or additional dedicated hardware for the prediction function.
3Ease of operation
If multiple parameters of symbols are varied (size, orientation, position, shape, brightness, color), then more intuitive warning signals are created, but the control complexity increases
Solution Approach 1:
The patent applies parameter changes by systematically varying multiple symbol attributes (position, size, shape, brightness, color) based on the predicted movement and urgency of the traffic situation. The control device adjusts these parameters in coordination to create intuitive visual warnings that convey different levels of risk and directional information to road users.

Function Achieved in This Case
The solution enables early warning of impending collisions by adapting symbols based on predicted road user movements, enhancing safety for both vehicle drivers and pedestrians by providing intuitive and timely information about potential hazards and intended vehicle maneuvers.
Implementation Method 1
a lighting module for generating a set of symbols on the ground in the immediate vicinity of the motor vehicle. Preferably, the lighting module is a projection module, which projects the symbols onto the ground in the vicinity of the motor vehicle
Data Source
AI summary
A motor vehicle including a lighting module that generates a set of symbols on the ground in the surroundings of the motor vehicle and a control device that controls the operation of the lighting module. The control device is designed such that it predicts the movement of a road user present in the surroundings of the motor vehicle based on information relating to the road user, and that it automatically adapts the set of symbols depending on the predicted movement of the road user.
