Processing Apparatus Layout to Reduce Pump Unit Installation Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing systems require larger installation areas due to separate locations for processing modules and pump units, leading to increased costs and reduced productivity per unit area.
Innovation Solution
A processing apparatus with a processing part containing multiple interconnected process modules in a first room and corresponding pump units in an adjacent second room, where the installation area of the pump units is equal to or smaller than the processing part, allowing for reduced footprint and improved productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If pump units are installed in a separate location from the processing part, then maintenance and replacement become easier, but the installation area increases
Solution Approach 1:
The patent utilizes the vertical dimension by installing pump units in the ceiling space above the clean room rather than placing them in a separate adjacent room. This dimensional transition allows the system to maintain compact horizontal footprint while providing accessible locations for pump unit maintenance and replacement through ceiling access points.
Solution Approach 2:
The pump units are nested within the ceiling structure of the clean room, effectively utilizing the vertical space above the processing area. This nesting approach allows the pump units to be positioned in a location that is both space-efficient (within the existing room envelope) and accessible for maintenance through the ceiling.
2Reliability
If pump units are installed in a separate location from the processing part, then interference with processing is reduced, but productivity per unit area decreases
Solution Approach 1:
By moving pump units to the ceiling dimension rather than placing them in a separate horizontal space, the patent maintains close spatial proximity between processing and pumping functions while eliminating interference. This vertical separation allows both functions to operate independently without compromising productivity per unit area.
3Area of stationary object
If pump units are arranged in the same room as processing modules, then installation area is reduced, but maintenance accessibility becomes difficult
Solution Approach 1:
The patent resolves this contradiction by transitioning the pump unit location to the vertical dimension (ceiling space), which simultaneously achieves compact horizontal installation area while providing accessible maintenance pathways through the ceiling structure.
Solution Approach 2:
The pump units are extracted from the main processing floor space and positioned in the ceiling space, creating a separate accessible zone for maintenance operations while maintaining functional integration with the processing modules below.
