Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing monitoring systems are implemented in reduced-crew aircraft, then pilot incapacitation detection capability is improved, but system cost and complexity increase significantly

Engineering Contradiction:
Improvepilot incapacitation detection capabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system monitors flight parameters and pilot activity automatically without requiring additional crew members. The existing flight control computer and system sensors are utilized to detect incapacitation events, making the system self-sufficient in reduced-crew configurations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The monitoring system serves multiple functions: it tracks flight parameters, monitors pilot activity levels, detects incapacitation events, and can interface with existing emergency protocols. This multi-functionality reduces the need for separate specialized systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If existing monitoring systems are implemented, then detection accuracy is improved, but installation difficulty increases

Engineering Contradiction:
Improveincapacitation detection accuracyVSAvoidinstallation ease
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The system integrates monitoring functions with the existing flight control computer and utilizes already-present sensors for flight parameter measurement. This merging approach eliminates the need for separate installation of dedicated monitoring hardware.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system uses the existing flight control computer as an intermediary to access flight parameter data and pilot activity information, avoiding the need for direct connections to multiple separate systems and simplifying installation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If continuous monitoring is implemented, then safety is improved, but energy consumption and operational cost increase

Engineering Contradiction:
Improveflight safetyVSAvoidsystem energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system continuously analyzes flight parameters but triggers detailed incapacitation assessment only when abnormal patterns are detected. This periodic intensive monitoring approach maintains safety while reducing overall computational energy consumption compared to constant full-scale analysis.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses feedback from flight parameter comparisons and pilot activity monitoring to dynamically adjust monitoring intensity. When parameters are normal and pilot activity is expected, monitoring operates at lower intensity, conserving energy while maintaining safety.

Inventive Principle:
Principle #23Feedback

AI summary

An aircraft pilot incapacitation detection system includes a controller configured to determine, based on an input received from a flight control computer, a current flight parameter. The controller compares the current flight parameter to a corresponding predetermined flight metric associated with at least one of a predetermined flight plan or a benchmark for a predetermined flight stage. The controller determines, responsive to the comparison, that the aircraft is in an abnormal state and causes a first prompt by a user interface in communication with the controller, the first prompt being associated with a first time threshold. The controller determines whether the first time threshold is satisfied and, if so, subsequently initiates an emergency protocol and causes a second prompt associated with a second time threshold. Upon determining that the second time threshold has been satisfied, the controller carries out the emergency protocol.
