Cleanroom Cleaning Apparatus with Segmented Saturation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleanroom cleaning methods face challenges with chemical dilution errors, contamination risks, and safety issues due to the need for operators to handle and apply chemicals directly, as well as the degradation of cleaning implements when stored with liquids.
Innovation Solution
A multi-compartment container with breakable seals allows for precise dilution and point-of-use saturation of cleaning implements with disinfectants or cleaning solutions, ensuring proper concentration and maintaining the structural integrity of the implements, while a nonbreakable outer pouch with a burstable inner pouch provides safe and efficient delivery of liquids to cleaning tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operators manually dilute and apply chemicals to cleaning implements inside cleanrooms, then flexibility and control in chemical application are improved, but contamination risk and safety hazards increase
Solution Approach 1:
The system divides the cleanroom environment into separate compartments: one containing the cleaning implement and another containing the chemical solution. This segmentation allows the implement to remain in a controlled, contamination-free zone while the chemical is stored separately, eliminating the need for operators to handle bulk chemicals inside the cleanroom.
Solution Approach 2:
A controlled delivery mechanism acts as an intermediary between the chemical storage compartment and the cleaning implement. This intermediary system enables precise chemical transfer without requiring operator intervention, thereby reducing contamination risk while maintaining application control.
2Ease of operation
If operators are responsible for chemical dilution, then operational flexibility is improved, but dilution errors and inconsistency increase
Solution Approach 1:
The system performs dilution automatically through pre-configured delivery mechanisms that control the amount of chemical transferred to the cleaning implement. This self-service approach eliminates manual dilution operations, ensuring consistent and accurate chemical concentrations without requiring operator skill or attention.
Solution Approach 2:
The chemical delivery system is pre-configured with controlled release mechanisms that automatically provide the correct amount of chemical. This preliminary setup ensures accurate dilution ratios are maintained without requiring operators to perform measurement and mixing operations during use.
3Ease of operation
If cleaning implements are stored with liquids in advance, then convenience of use is improved, but structural integrity of implements deteriorates
Solution Approach 1:
The system separates the cleaning implement storage compartment from the chemical storage compartment, preventing premature contact between the implement and liquid. This segmentation allows the implement to maintain its structural integrity during storage while still being conveniently ready for use, as the chemical is delivered only when needed.
Solution Approach 2:
The system transitions from a static pre-saturated state to a dynamic on-demand saturation approach. The cleaning implement remains dry and structurally sound during storage, then dynamically receives the required chemical amount at the moment of use, preserving integrity while maintaining convenience.
4Ease of operation
If chemicals are stored in containers inside cleanrooms, then accessibility is improved, but safety risks increase
Solution Approach 1:
The system segregates chemical storage into a separate compartment isolated from the main cleanroom environment. This segmentation maintains accessibility to the cleaning implement while protecting the cleanroom from chemical storage hazards, as the chemical container is confined to a dedicated zone that prevents spills and contamination.
Solution Approach 2:
A controlled delivery mechanism serves as an intermediary between the isolated chemical storage and the cleaning implement. This intermediary system enables chemical transfer without requiring operators to access or handle chemical containers inside the cleanroom, thereby maintaining accessibility while eliminating safety hazards associated with chemical container handling.

AI summary
A cleanroom cleaning device includes a multi-compartment container having two or more compartments and one or more breakable seals with at least one compartment containing a cleaning implement and at least another compartment containing a liquid capable of saturating the cleaning implement when the seals are broken. Another cleanroom cleaning device includes a nonbreakable/nonburstable outer pouch, a breakable/burstable inner pouch containing a liquid, and a cleaning implement where the inner pouch containing liquid and the cleaning implement are both contained within the outer pouch.
