Vehicle Window Submergence Detection and Auto-Open System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers and passengers often drown in vehicles submerged in water due to the inability to open power windows, as water infiltration prevents manual operation and pressure equalization is delayed, leading to fatal outcomes.
Innovation Solution
A submergence detection system automatically opens all front and rear side power windows of a vehicle upon water immersion, using a water collector and electronics component to form a closed circuit and activate relay switches, ensuring windows are opened before water pressure becomes lethal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power windows are made manually operable, then ease of operation is improved, but water infiltration prevents operation during submersion
Solution Approach 1:
The system automatically detects water submersion and triggers window opening without requiring manual operation by occupants. The water detection system and automated control mechanism enable the windows to open themselves when needed, eliminating the need for manual operation during emergency submersion conditions.
Solution Approach 2:
The patent replaces manual mechanical window operation with an automated electromechanical system. Water detection triggers an electrical control system that activates motors to open windows automatically, substituting the need for manual mechanical manipulation that fails during submersion due to water infiltration and pressure.
2Loss of time
If automated water detection system is added, then survival time is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary water detection and automatically initiates window opening before water reaches critical levels that would prevent escape. By detecting submersion early and triggering the window opening sequence proactively, the system saves critical time without requiring complex real-time pressure equalization control.
Solution Approach 2:
The patent introduces a water detection system as an intermediary between submersion conditions and window opening action. This intermediary sensor system detects water presence and triggers the automated window opening sequence, simplifying the overall control logic compared to complex pressure-sensing or manual-trigger systems.

AI summary
A system can automatically open at least one window of a vehicle when the vehicle is being submerged in water. The system can include a water collector and a water sensor, and when the water sensor detects water in the water collector, at least one window of the vehicle opens.
