Windshield Wiper Alarm Module for Obstructed Driver Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Restricted visibility during rainy conditions makes it difficult for drivers to recognize targets like lane markings or other vehicles, increasing the risk of traffic accidents due to obstructed sight lines caused by windshield wipers.
Innovation Solution
A driving assistance system featuring an alarm module on the windshield wiper that acquires images of the target and itself from the driver's perspective, determining overlapping regions to present prompt information, such as images or lighting, to alert the driver of the target's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a windshield wiper is used to clear rain from the windshield, then visibility is improved, but the wiper obstructs the driver's sight line and makes it difficult to recognize targets
Solution Approach 1:
The patent introduces an alarm module as an intermediary device that detects targets obscured by the windshield wiper and provides visual alerts to the driver. The alarm module includes sensors to detect lane markings, pedestrians, and vehicles, and displays warnings when these targets are blocked by the wiper's movement, thereby mediating between the wiper's cleaning function and the driver's need for unobstructed vision.
Solution Approach 2:
The system implements feedback by continuously monitoring the driver's field of view and providing real-time alerts when the windshield wiper blocks important visual information. The alarm module receives data from sensors about target positions and wiper movement, processes this information, and provides feedback to the driver through visual warnings, enabling the driver to adjust their attention or the wiper operation accordingly.
2Reliability
If the alarm module is placed on the windshield wiper, then it can effectively monitor and alert about overlapping regions, but the device complexity increases
Solution Approach 1:
The patent merges the alarm module with the existing windshield wiper structure, integrating sensors, processing units, and display elements into a single compact system mounted on the wiper. This consolidation reduces the need for separate components and simplifies installation while maintaining the reliability benefits of having the alarm function closely coupled with the wiper's movement and monitoring capabilities.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents traffic accidents by providing real-time alerts about the target's position, improving driving safety by reducing the obstructive effect of the windshield wiper on the driver's view.
Implementation Method 1
a first collection unit configured to collect a third image including the target viewed at a second position
Implementation Method 2
the alarm module is a light-emitting diode (LED) light bar or a flexible display

AI summary
A vehicle, a driving assistance system and a driving assistance method thereof are provided. The driving assistance system includes: an alarm module arranged on a windshield wiper and configured to present prompt information; an acquisition module configured to acquire a first image including a target outside a vehicle viewed at a first position and a second image including the alarm module viewed at the first position, the first position being a position where eyes of a driver are located; and a control module configured to determine an overlapping region between a region of the second image occupied by the alarm module and a region of the first image occupied by the target, and control the alarm module to present the prompt information about the overlapping region.
