Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Complex engineered systems, such as aircraft, face challenges in autonomous control due to human errors, inefficiencies, and the need for extensive testing, which can compromise safety and reliability, especially when dealing with dynamic environments and failures.
Innovation Solution
A programmed computer/server system implementing a temporal sequencer and immediate redecider structure, which decouples control systems and uses tile-based decision-making to provide autonomous control, allowing for quick reactions to discontinuities and efficient stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual control is used for complex engineered systems, then human operators can handle dynamic environments and failures, but operator errors, inexperience, and human impairment compromise safety and reliability
Solution Approach 1:
The control system performs autonomous control without human intervention, allowing the system to serve itself by making control decisions based on sensor inputs and predefined logic, thereby eliminating operator errors while maintaining safety and reliability
Solution Approach 2:
The patent replaces human mechanical control with an automated control system that uses sensors, processors, and actuators to perform control functions, substituting human operators with a mechanical/electronic system that does not suffer from human limitations
2Reliability
If extensive testing is performed on autonomous control systems, then safety and reliability improve, but testing complexity and time increase
Solution Approach 1:
The control system is divided into modular components (sensors, processors, control logic, actuators) that can be independently tested and validated, reducing overall testing complexity while maintaining comprehensive safety verification
Solution Approach 2:
The control logic and decision-making algorithms are predefined and programmed before deployment, allowing extensive validation and testing to be performed in advance, thereby reducing the need for complex real-time testing while ensuring safety and reliability
3Productivity
If autonomous control is implemented, then human intervention is reduced and operational efficiency improves, but handling dynamic environments and failures becomes more challenging
Solution Approach 1:
The control system continuously receives feedback from sensors about system state and environmental conditions, allowing it to adapt to dynamic environments in real-time while maintaining autonomous operation and high operational efficiency
Solution Approach 2:
The control logic is designed to be dynamic and adaptive, capable of responding to changing conditions and failures through predefined decision trees and control algorithms that adjust control actions based on current system state, thereby maintaining versatility without requiring human intervention

AI summary
A decided sequence of steps selected from a set of sequences of steps defined for a control system is executed to effect control of by writing a control variable to an actuator. At each timestep, it is redecided whether the decided sequence of steps or an alternate sequence of steps is to be executed.
