Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control instructions are sent to multiple controlled components in a distributed control system, then the control function can be completed, but communication delays and response duration differences cause asynchronous execution leading to mechanical or electrical overload
Solution Approach 1:
The controller performs preliminary actions by calculating the response durations of multiple controlled components in advance, determining the maximum response duration, and computing delay durations for each component before sending control instructions. This preliminary calculation enables synchronous execution without requiring complex real-time synchronization mechanisms.
Solution Approach 2:
The invention changes the timing parameter of control instruction transmission by introducing calculated delay durations for different controlled components. By adjusting when each component receives its control instruction based on its response characteristics, the system achieves synchronous operation despite inherent response time differences.
2Adaptability or versatility
If control instructions are transmitted through slave controllers in a distributed system, then system architecture flexibility is maintained, but communication delays increase causing execution asynchrony
Solution Approach 1:
The master controller performs preliminary calculation of delay durations by considering the communication period between master and slave controllers. This advance calculation compensates for the inherent communication delays in the distributed architecture, allowing synchronized execution without requiring faster communication hardware.
Solution Approach 2:
The invention uses the slave controller as an intermediary that receives control instructions from the master controller and forwards them to controlled components. By calculating appropriate delay durations that account for communication periods, the system maintains the benefits of distributed architecture while achieving synchronous operation.
3Productivity
If controlled components execute control instructions at different speeds, then individual component performance is optimized, but synchronous completion of control functions cannot be achieved
Solution Approach 1:
The invention changes the transmission timing parameter of control instructions by introducing delay durations tailored to each controlled component's response characteristics. This parameter adjustment allows components to execute at their natural speeds while still completing operations synchronously, maintaining both productivity and reliability.
Solution Approach 2:
The controller performs preliminary calculation of delay durations based on each component's response duration before sending control instructions. This advance preparation enables the system to accommodate different execution speeds while ensuring synchronous completion, without requiring components to operate at reduced speeds.
