Semiconductor Transfer Path Optimization for Energy Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Semiconductor production plants face inefficiencies in energy consumption due to wasteful energy use by transfer apparatuses that circulate without contributing to product manufacture and inefficient selection of transfer carriages and processing apparatuses, leading to extended transfer paths and increased energy consumption.
Innovation Solution
A production efficiency improvement system that selects a processing apparatus with the shortest transfer distance from a predetermined position on the transfer path, considering the position of each processing apparatus, to minimize energy consumption by optimizing the transfer path and reducing unnecessary energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transfer apparatus circulates on the transfer path to calculate unloading timing until the processing apparatus enters a ready state, then the workpiece can be mounted on the processing apparatus, but the transfer apparatus consumes wasteful energy during circulation
Solution Approach 1:
The system performs preliminary actions by having the processing apparatus prepare its ready state in advance and notifying the transfer apparatus beforehand. This allows the transfer apparatus to plan its circulation and unloading timing in advance, reducing unnecessary circulation and energy consumption while ensuring reliable workpiece mounting when needed.
Solution Approach 2:
The processing apparatus provides feedback to the transfer apparatus about its ready state and unloading timing requirements. This feedback mechanism enables the transfer apparatus to optimize its circulation path and timing, avoiding wasteful energy consumption while maintaining reliable workpiece delivery.
2Ease of operation
If only a proper transfer carriage is selected without considering selection of a proper processing apparatus, then transfer carriage selection is simplified, but the transfer path is extended resulting in wasteful energy consumption
Solution Approach 1:
The system applies local quality by making the selection process location-aware. When selecting a processing apparatus, the system considers the positional relationship between the transfer carriage and available processing apparatuses, choosing the nearest suitable apparatus to minimize transfer distance and energy consumption while maintaining operational simplicity.
Solution Approach 2:
The system changes the selection parameter from solely considering transfer carriage compatibility to also considering spatial position and transfer distance. This parameter expansion enables optimized selection of processing apparatuses that are both compatible with the transfer carriage and positioned to minimize energy consumption.
