Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a remote operator station is used to control machines from a safe location, then operator safety is improved, but the complexity of the control system increases
Solution Approach 1:
The patent introduces an autonomy electronic control module (AECM) as an intermediary between the remote operator station and the vehicle electronic control modules. The AECM receives input control signals from the remote operator station, processes them autonomously, and generates output control signals to control vehicle operations. This intermediary architecture enables safe remote operation while managing system complexity through modular design.
2Adaptability or versatility
If multiple electronic control modules and communication networks are implemented, then machine control functionality is improved, but the device complexity increases
Solution Approach 1:
The patent divides the control system into multiple independent electronic control modules (ECMs), each responsible for specific vehicle functions. The AECM is segmented as a separate autonomous control unit that interfaces with multiple vehicle ECMs through standardized communication protocols. This segmentation allows for enhanced functionality while managing complexity through modular, independent components.
Solution Approach 2:
The AECM is designed as a universal control module that can interface with multiple different vehicle ECMs and support various control functions through a single standardized platform. This multi-functional design enables the system to handle diverse machine control requirements without proportionally increasing overall system complexity.
3Productivity
If real-time control signals are transmitted from remote location, then operational efficiency is improved, but the loss of time in signal transmission and processing increases
Solution Approach 1:
The AECM is pre-configured with autonomous control algorithms and decision-making capabilities that enable it to process input control signals and generate output control signals without requiring extensive real-time computation or human intervention. This preliminary preparation of control logic reduces signal processing time and maintains operational efficiency.
Solution Approach 2:
The system implements feedback mechanisms where the AECM continuously monitors vehicle status and control signal effectiveness, adjusting its processing in real-time. This feedback loop optimizes signal transmission and processing efficiency by adapting to actual system conditions, reducing unnecessary processing delays.
