Windshield Invisible Area for Hiding Road Scenes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for displaying information on windshields fail to effectively hide unpleasant road scenes like animal roadkill, accidents, and garbage from drivers and passengers, while maintaining visibility of essential road information, which disrupts safe driving and passenger comfort.
Innovation Solution
Implementing a system that uses transparent LCD or OLED displays or electrochromic films on windshields to create an invisible area for undesirable road scenes, while overlaying or projecting essential road information using cameras and projectors, and adjusting the position of the invisible area based on vehicle movement and passenger gaze recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an invisible area is created on the windshield to hide unpleasant road scenes, then passenger comfort is improved, but visibility of essential road information deteriorates
Solution Approach 1:
The patent applies different optical properties to different regions of the windshield. The invisible area uses a film or display that blocks or blurs unpleasant scenes, while surrounding areas maintain full transparency. This local differentiation allows hiding specific unwanted views without compromising overall visibility of important road information.
Solution Approach 2:
The windshield is divided into distinct functional zones: visible areas for normal viewing and an invisible area for hiding unpleasant scenes. This segmentation allows independent control of each region's optical properties, enabling selective obscuration without affecting other parts of the windshield.
2Reliability
If road information is overlaid on the invisible area, then safe driving is improved, but the invisible area becomes less effective at hiding unpleasant scenes
Solution Approach 1:
The patent employs asymmetric optical treatment where road information is selectively projected or displayed only within the invisible area. The overlay uses different optical characteristics (such as enhanced brightness or contrast) compared to the surrounding visible areas, allowing critical information to stand out while the rest of the invisible area maintains its obscuring function.
Solution Approach 2:
The patent utilizes changes in optical properties including color, brightness, or contrast to differentiate the overlaid road information from the hidden unpleasant scenes. The display system adjusts the optical characteristics of the invisible area to ensure road information is clearly visible while unpleasant content remains concealed.
3Measurement precision
If the invisible area position is adjusted based on vehicle movement, then tracking accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements a dynamic positioning system that automatically adjusts the invisible area's location on the windshield based on real-time vehicle movement data. The system responds to changes in vehicle position, orientation, and motion to maintain accurate alignment of the invisible area with unpleasant road scenes, transforming a static obscuration system into an adaptive one.
Solution Approach 2:
The patent incorporates feedback mechanisms that continuously monitor vehicle movement and adjust the invisible area position accordingly. Sensors detect vehicle position and motion, and this information feeds back to the display or film control system to realign the invisible area, creating a closed-loop control system that maintains accuracy despite vehicle dynamics.
4Object-affected harmful factors
If gaze recognition is used to adjust invisible area position, then passenger-specific comfort is improved, but processing complexity increases
Solution Approach 1:
The patent enables the system to automatically adapt to individual passenger needs through gaze recognition. By detecting where passengers are looking, the system autonomously adjusts the invisible area position to hide unpleasant scenes in each passenger's field of view without requiring manual input, making the system self-adapting to individual preferences and positions.
Solution Approach 2:
The patent changes the positioning parameters of the invisible area based on detected gaze directions and passenger positions. The system adjusts coordinates, orientation, and size of the invisible area to match each passenger's line of sight, dynamically modifying system parameters to optimize comfort for different users.

AI summary
Inventive concepts are configured to protect a passenger by processing an area in a windshield, which matches to a position of a spot on a road, wherein the spot is defined as desirable to not be seen by the passenger when a vehicle is travelling. To this end, the area in the windshield, which matches to a spot on an actual road defined in advance as desirable to not be seen by the passenger, is processed as an invisible area for passenger protection so that the passenger is prevented from visually recognizing the spot. However, when road information required for driving of the vehicle is occluded due to the invisible area which is processed or displayed on the windshield, safe driving is significantly disrupted so that actual road information is overlaid on the invisible area.
