Reactor Mover Layout for Safe Substrate Tool Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substrate processing apparatuses face challenges in maintaining reactors due to their inaccessible location at a substantial height within the apparatus, making maintenance difficult and risky for workers.
Innovation Solution
A reactor mover is introduced, comprising a lift and a displacer to move the reactor to a lower height and outside the apparatus for easy access by maintenance workers, allowing for maintenance in a separate maintenance area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the reactor is mounted at a substantial height within the apparatus, then the apparatus footprint is reduced, but the reactor becomes inaccessible for maintenance workers
Solution Approach 1:
The reactor is mounted on a movable platform that can be dynamically repositioned between an operational position (mounted in the apparatus) and a maintenance position (lowered and moved outside). This dynamic positioning system allows the reactor to be accessible for maintenance while maintaining a compact footprint during operation.
Solution Approach 2:
A reactor mover system acts as an intermediary mechanism between the reactor and the maintenance worker. This system includes a platform, displacer, and lift that collectively enable the reactor to be moved and lowered to a maintenance area, bridging the gap between the compact operational configuration and the accessible maintenance configuration.
2Device complexity
If the reactor components are mounted at substantial height, then the apparatus structure is compact, but maintenance workers face safety hazards and contamination risks
Solution Approach 1:
The reactor and its components can be dynamically repositioned from a high-mounted operational position to a low-mounted maintenance position. This dynamic repositioning eliminates worker exposure to hazards and contamination risks during maintenance while maintaining structural compactness during operation.
Solution Approach 2:
The reactor is extracted from its fixed high-mounted position and placed on a movable platform that can be removed from the apparatus. This extraction allows the reactor to be taken out to a separate maintenance area, isolating the maintenance activity from the operational apparatus and eliminating worker exposure risks.
3Device complexity
If the reactor is fixed in position within the apparatus, then the apparatus structure is simple, but maintenance requires complex access mechanisms
Solution Approach 1:
Instead of a fixed reactor requiring complex access mechanisms, the system uses a dynamically repositionable reactor on a movable platform. This dynamic system simplifies maintenance by directly moving the reactor to an accessible position rather than requiring workers to access high-mounted components.
Solution Approach 2:
The reactor mover system serves as an intermediary that simplifies the maintenance process. Rather than requiring workers to access the reactor in its fixed position, the intermediary system moves the reactor to a maintenance area where standard access and maintenance procedures can be used.
