Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If initial position setting is performed for each transfer shaft sequentially, then setup accuracy is ensured, but work efficiency decreases and setup time increases
Solution Approach 1:
The system performs preliminary determination of parallel executability before initiating initial position setting operations. The controller checks whether multiple transfer shafts can be set in parallel based on their interrelationships, and only allows parallel setting when safe, thus preparing the system in advance to maximize efficiency without compromising accuracy
Solution Approach 2:
The initial position setting process is segmented into individual transfer shaft operations that can be independently controlled. The system divides the overall setup into discrete units (transfer shafts) that can be processed separately or in parallel groups, allowing flexible scheduling and optimization of setup operations
2Productivity
If parallel initial position setting is performed for multiple transfer shafts, then work efficiency improves and setup time reduces, but risk of collisions and setup errors increases
Solution Approach 1:
The system continuously monitors the state of each transfer shaft during initial position setting and provides feedback to the controller. The determination processor uses this feedback to dynamically adjust which shafts can be set in parallel, ensuring that collision risks are detected and prevented while maintaining maximum parallelism for efficiency
Solution Approach 2:
The system performs preliminary checks to identify and prevent potential collisions before they occur. The determination processor analyzes the spatial relationships and movement paths of transfer shafts to proactively prevent unsafe parallel operations, counteracting potential harmful effects before they manifest
3Reliability
If the system provides detailed status display and determination processing, then operator awareness and safety improve, but device complexity increases
Solution Approach 1:
The system performs self-determination of parallel executability using automated algorithms in the determination processor. Rather than requiring complex manual analysis by operators, the system autonomously evaluates whether parallel setting is safe, reducing the burden on operators while maintaining high safety standards through intelligent automation

AI summary
It is possible to suppress a decrease in work efficiency in an initial position setting operation for a substrate processing apparatus. There is provided a technique that includes: transporters each provided with one or more transfer shafts; a manipulator for selecting a specified transfer shaft from the one or more transfer shafts and performing an initial position setting therefor; a display for displaying a status of the initial position setting for the specified transfer shaft; and a controller including a determination processor and notifying a determination result determined by the determination processor, wherein the determination processor determines whether the initial position setting for the specified transfer shaft selected by the manipulator is completed and whether it is possible for an initial position setting for another transfer shaft to be performed in parallel.
