Rupturable Pouch Cleaning Kit for Leak-Safe Wiper Saturation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning kits for clean rooms and pharmaceutical facilities face issues with contamination due to pre-saturated wipers, where the cleaning solution degrades the wiper material over time, and point-of-use saturation systems suffer from leakage, bulkiness, and difficulty in saturating wipers effectively during shipping and handling.
Innovation Solution
A cleaning kit design featuring a first liquid-tight container with a second liquid-tight container that includes a baffle and a frangible seal, allowing the second container to be ruptured by user pressure, reducing accidental rupture during shipping and ensuring easy saturation of wipers with cleaning fluid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-saturated wipers are stored for prolonged periods, then the wipers are ready for immediate use, but the cleaning liquid degrades the wiper material and increases contaminant release
Solution Approach 1:
The system divides the cleaning components into separate segments: the wiper material is packaged separately from the cleaning liquid. The cleaning liquid is contained in a reservoir that can be activated at the point of use, allowing the wiper to remain dry and uncontaminated during storage and transport, thus eliminating the contaminant release issue while maintaining readiness for use.
Solution Approach 2:
The wiper material is pre-packaged in a sterile, sealed state ready for use, and the cleaning liquid is pre-filled in the reservoir. At the point of use, the system activates the liquid delivery mechanism to saturate the wiper, combining the benefits of pre-preparation with minimal contact time between liquid and wiper material.
2Ease of operation
If point-of-use saturation systems are designed to be rupturable, then easy saturation is achieved, but accidental rupture during shipping increases
Solution Approach 1:
The system employs a dynamic sealing mechanism that transitions from a sealed state during shipping to an open state during use. The reservoir incorporates a frangible seal or valve that remains intact during normal handling but can be easily activated by user action, providing both shipping durability and ease of saturation.
Solution Approach 2:
The system introduces an intermediary activation mechanism between the user and the cleaning liquid. This could be a breakable seal, valve, or activation button that requires deliberate user action to open, preventing accidental rupture during shipping while ensuring easy activation when needed.
3Object-generated harmful factors
If cleaning liquid is applied from separate containers to dry wipers, then contamination is minimized, but the amount of cleaning fluid used is either too little or too much
Solution Approach 1:
The system employs a self-regulating liquid delivery mechanism that automatically controls the amount of cleaning liquid applied to the wiper. The reservoir and wiper interaction is designed to saturate the wiper with the appropriate amount of liquid through capillary action, gravity feed, or controlled dispensing, eliminating the need for user judgment and preventing both under-saturation and oversaturation.
Solution Approach 2:
The system may incorporate pneumatic or hydraulic principles to control liquid flow, such as pressure-regulated dispensing or capillary wick structures that automatically draw the correct amount of liquid from the reservoir to the wiper, ensuring consistent and controlled application without user intervention.

AI summary
The cleaning kit includes a first liquid-tight container and a second liquid-tight container adapted to be received within the first container to be ruptured by the application of pressure to the container by a user. The second container includes a sealable liquid-tight pouch; a baffle extending at least partially across the pouch adapted to reduce accidental rupture caused by handling during shipping and a frangible seal along at least a portion of an outer edge of the pouch. A cleaning liquid may be in the second container, wherein the second container is adapted to be openable while it is located in the first container to release the liquid from the second container into the first container. Also, there may be at least one absorbent applicator in the first container and adjacent to the second container in the first container whereby the release of cleaning liquid from the second container is applied to the applicators in the first container.
