Solution Overview
Problem
Existing industrial machine control systems face challenges in quickly and accurately executing control commands due to time-consuming analysis processes and potential errors in reflecting analysis results, leading to inefficiencies and inaccuracies in machine operations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If control commands are processed through traditional analysis processes, then accuracy can be maintained, but execution time increases and productivity decreases
Solution Approach 1:
The patent segments the control system into multiple independent units (first industrial machine, second industrial machine, control circuits) that can operate autonomously. Each unit has dedicated storage areas and rewriting modules, allowing parallel processing of control commands without centralized bottlenecks, thus improving execution speed while maintaining accuracy through distributed verification.
Solution Approach 2:
The system performs preliminary actions by pre-defining storage areas (first storage, second storage, third storage) and establishing rewriting rules before control commands are issued. Variables are pre-configured with their storage locations and rewriting conditions, enabling immediate execution upon command receipt without time-consuming analysis or decision-making during runtime.
2Stability of the object's composition
If traditional control systems are used, then system stability is maintained, but adaptability to new control commands decreases
Solution Approach 1:
The patent implements dynamic adaptability through the rewriting module that can modify variable values based on incoming control commands. The system transitions from static pre-programmed control to dynamic reconfigurable control, where the first industrial machine can adapt its operation by rewriting variables in real-time while maintaining overall system stability through structured storage areas and controlled rewriting processes.
Solution Approach 2:
The system enables adaptability by allowing parameter changes through the rewriting of variables. The control commands modify variable values (parameters) stored in the storage areas, enabling the first industrial machine to adapt its behavior. The structured approach with dedicated storage areas ensures that parameter changes are controlled and systematic, maintaining stability while achieving versatility.
3Loss of information
If multiple storage areas are used for variable management, then data organization improves, but device complexity increases
Solution Approach 1:
The patent divides the storage system into three distinct segments: first storage (for variable definitions), second storage (for current variable values), and third storage (for rewriting buffers). This segmentation prevents data confusion and loss by assigning specific functions to each storage area, while the modular structure makes the complexity manageable through clear separation of concerns.
Solution Approach 2:
The second storage area acts as an intermediary between the first storage (variable definitions) and the third storage (rewriting operations). This intermediary structure facilitates organized data flow and transformation, reducing information loss by providing a controlled transition zone. The intermediary storage simplifies the overall complexity by creating a structured buffer zone that manages the interaction between different storage functions.
