Vehicle Submergence Detection System for Automatic Window Escape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers and passengers often drown when their vehicles submerge 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 a vehicle's power windows by forming a closed circuit with rising water, using a water collector and electronic components to activate relay switches, ensuring windows open before water pressure equalsizes and trapping occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power windows are manually operated, then windows can be opened or closed, but when water infiltrates the switch, the window cannot be opened
Solution Approach 1:
The system performs preliminary action by automatically opening the power windows before water infiltration renders manual operation impossible. The water level sensor detects rising water and triggers automatic window opening in advance, preventing the harmful effect of water infiltration on switch operation.
Solution Approach 2:
The system implements self-service by automatically detecting water infiltration conditions and opening windows without requiring manual switch operation. The electronic control system serves itself by monitoring water level and autonomously activating the window opening function when needed.
2Strength
If vehicle doors and windows are sealed, then vehicle structure integrity is maintained, but occupants cannot escape during submersion
Solution Approach 1:
The system applies preliminary action by automatically opening windows before water pressure equalizes and before occupants lose consciousness. This preliminary escape opportunity is created while the vehicle structure remains intact, resolving the contradiction between structural integrity and escape capability.
Solution Approach 2:
The system replaces manual mechanical window operation with an electronic control system. The electronic control module activates the power window motors to open windows automatically, substituting the mechanical switch-operated system with an electronically controlled one that can function even when manual operation becomes impossible.
3Loss of time
If automatic window opening system is implemented, then escape time is provided, but device complexity increases
Solution Approach 1:
The system achieves universality by using existing power window motors and control infrastructure for the emergency escape function. The electronic control module integrates with the vehicle's existing power window system, allowing the same mechanical components to serve both normal window operation and emergency escape functions, thereby minimizing additional complexity.
Solution Approach 2:
The system introduces an intermediary electronic control module that acts as a mediator between the water level sensor and the power window motors. This intermediary component coordinates the automatic window opening function while leveraging existing system components, balancing the need for automated escape with constraints on system complexity.
