Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic control is used for working machines, then labor cost is reduced and automation level is improved, but when the working machine stops, the system cannot respond quickly leading to work efficiency degradation
Solution Approach 1:
The control system dynamically switches between automatic control and remote control modes based on real-time monitoring of working machine status. When a machine is detected to be stopped or malfunctioning, the system automatically transitions from static automatic control to dynamic remote control, allowing operators to intervene and resume work, thereby maintaining high productivity while preserving automation benefits during normal operation
Solution Approach 2:
The system implements continuous feedback monitoring of working machine status including operation state, location, and performance metrics. This feedback mechanism enables the centralized operation controller to detect when automatic control fails or machines stop, triggering a switch to remote control mode. The feedback loop ensures rapid response to maintain work efficiency while preserving automation during successful operations
2Reliability
If remote control is switched to multiple working machines, then response to stoppages is improved, but without selection criteria it is difficult to constantly select the appropriate machine leading to system efficiency degradation
Solution Approach 1:
The system pre-establishes selection criteria and algorithms in the centralized operation controller that automatically identify which working machine should be switched to remote control based on monitored parameters such as stoppage duration, machine priority, work progress, and operator availability. This preliminary configuration enables immediate appropriate machine selection without manual decision-making, maintaining both high reliability and system efficiency
Solution Approach 2:
The system enables self-service through automated machine selection and control mode switching without requiring manual operator intervention for each decision. The centralized operation controller autonomously monitors all working machines, applies selection criteria, and switches appropriate machines to remote control mode, thereby maintaining high system efficiency while ensuring reliable response to stoppages
3Adaptability or versatility
If a centralized operation controller manages multiple working machines, then overall system coordination is improved, but without work progress calculation it is difficult to determine switching timing leading to work efficiency loss
Solution Approach 1:
The system pre-calculates work progress metrics and establishes switching threshold criteria before operation begins. The centralized operation controller continuously compares real-time work progress against these pre-established thresholds to determine optimal switching timing from automatic to remote control. This preliminary preparation enables efficient decision-making that maintains both system coordination and work efficiency
Solution Approach 2:
The system replaces manual judgment and mechanical decision-making with automated electronic calculation of work progress and switching timing. The centralized operation controller uses computational algorithms to continuously assess work progress metrics and automatically determine when to switch control modes, thereby achieving superior system coordination and work efficiency compared to manual methods
