Ejection Seat Controller for Automatic Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft ejection systems require manual activation by the seat occupant, which can be impossible if the occupant is incapacitated, leading to potential failure in emergency situations.
Innovation Solution
A smart deployment system that uses a combination of pilot health monitoring sensors and aircraft health monitoring systems to autonomously determine the occupant's consciousness and awareness, and initiate the ejection sequence or alert the pilot based on impending danger, with the ability to override manual control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual activation is used, then the system is simple and reliable, but the occupant cannot activate ejection if incapacitated
Solution Approach 1:
The system monitors the occupant's physiological state and automatically activates ejection without requiring manual input from the occupant. The controller detects incapacitation through sensor data and autonomously triggers the ejection sequence, allowing the system to serve itself rather than requiring human action.
Solution Approach 2:
The patent replaces the mechanical manual pull-handle activation system with an electronic automated system. Sensors detect physiological parameters (heart rate, breathing, muscle activity) and the controller processes this data to electronically trigger ejection, substituting mechanical human action with electronic detection and actuation.
2Reliability
If automated ejection is implemented, then ejection can occur when occupant is incapacitated, but false activation may occur
Solution Approach 1:
The system continuously monitors multiple physiological parameters and uses feedback from these sensors to determine occupant state. The controller processes ongoing data streams from heart rate, breathing rate, and muscle activity sensors to make real-time decisions about ejection activation, allowing dynamic adjustment based on current physiological state.
Solution Approach 2:
The system performs preliminary monitoring and assessment of the occupant's physiological state before initiating ejection. By continuously tracking vital signs and detecting changes that indicate incapacitation, the system prepares for potential ejection activation while maintaining safety checks to prevent false triggers.
3Measurement precision
If multiple sensors are used to monitor occupant state, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The patent combines multiple physiological monitoring functions into a single integrated sensor system. Sensors for heart rate, breathing rate, and muscle activity are merged into a unified monitoring platform that feeds data to a common controller, reducing overall system complexity while maintaining multi-parameter monitoring capabilities.
Solution Approach 2:
The sensor system is designed with multi-functionality, where sensors can detect multiple physiological parameters simultaneously. The controller is programmed to process various types of physiological data and make ejection decisions based on综合分析 of all sensor inputs, allowing a single system to perform multiple monitoring functions.

AI summary
An ejection system may comprise an ejection seat and a smart deployment system configured to initiate a deployment of the ejection seat. The smart deployment system may comprise a pilot health monitoring system including a plurality of sensors configured to detect a plurality of physiological conditions, and a controller configured to make ejection system decisions based on a pilot health signal received from the pilot health monitoring system and an aircraft health signal output from an aircraft health monitoring system.
