Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assistance systems in controlled systems, such as aircraft, often react with delays to changing situations due to time-lagged detection of state changes, leading to potential safety risks, especially when human intervention is possible.
Innovation Solution
An acoustic recording and processing unit is integrated to analyze voice communications between relevant individuals, allowing for real-time adaptation of state detection and prediction, enhancing the accuracy of speech recognition and support recommendations by considering future speech hypotheses and context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If assistance systems use sensor systems to detect current status of controlled system, then measurement precision is improved, but loss of time occurs due to delayed detection of state changes
Solution Approach 1:
The system performs preliminary actions by detecting speech information before actual state changes occur in the controlled system. When speech indicating a desired state change is detected, the system proactively updates the detected state to match the anticipated future state, enabling the assistance system to react without delay when the actual change occurs.
Solution Approach 2:
The system cushions against future state changes by pre-updating the detected state based on speech information. This beforehand cushioning ensures that when the actual state change occurs, the system is already prepared and can provide immediate appropriate support measures without experiencing response delay.
2Reliability
If assistance systems provide support measures based on detected state, then reliability is improved, but loss of time occurs when state changes are not recognized in good time
Solution Approach 1:
The system takes preliminary action by updating the detected state in advance based on speech information before the actual state change occurs. This allows the assistance system to maintain reliability by having the correct state information ready, ensuring safe and timely support measures when the actual change occurs.
3Measurement precision
If speech recognition analyzes recorded acoustic signals, then measurement precision is improved, but device complexity increases due to additional processing units
Solution Approach 1:
The speech processing unit serves multiple functions: it recognizes speech information from acoustic signals, determines desired state changes, and updates the detected state accordingly. This multi-functionality reduces the need for separate dedicated components, managing device complexity while maintaining high speech recognition accuracy.
