Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing marking methods are used, then marking can be performed on the electrode plate material strip, but the marking process is low in efficiency and causes delays
Solution Approach 1:
The patent combines the marking device and deviation correction device under a single controller, merging previously separate control systems. This integration enables coordinated operation of multiple devices, eliminating communication delays between separate controllers and significantly improving marking efficiency while reducing marking delays.
Solution Approach 2:
The controller pre-calculates the to-be-marked position on the electrode plate material strip based on detection signals before the material strip arrives at the marking location. By determining the marking position in advance and preparing the marking device, the system eliminates waiting time and ensures immediate marking when the material strip is in position, thereby improving productivity and reducing delays.
2Ease of operation
If multiple separate controllers are used for different devices, then each device can be controlled independently, but the control system becomes complex
Solution Approach 1:
The patent consolidates control of the marking device, deviation correction device, and conveying mechanism into a single controller. This merges multiple independent control systems into one unified system, reducing the number of controllers from multiple to one, simplifying the overall control architecture, and eliminating the complexity of inter-controller communication while maintaining independent device control capabilities through software modules.

AI summary
A device control method applied to a first controller includes: receiving a first detection signal sent by an upper-level computer, the first detection signal being a signal obtained by the upper-level computer upon detecting quality of a target material strip; determining a to-be-marked position on the target material strip based on the first detection signal; controlling a marker to set a mark at the to-be-marked position on the target material strip; receiving a second detection signal sent by the upper-level computer, the second detection signal being a signal obtained by the upper-level computer upon detecting a position of the target material strip; determining a deviation correction position on the target material strip based on the second detection signal; and controlling a deviation corrector to adjust the deviation correction position on the target material strip.
