Wipes Bag Membrane Segmentation for Moisture Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tissue wipes dry out quickly when exposed to air due to solvent evaporation, reducing their effectiveness in cleaning surfaces.
Innovation Solution
A plastic film bag with a resealable closure and a membrane that divides the bag into a contents storage chamber and an access chamber, preventing air from reaching the wipes and maintaining their moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bag is opened for access to wipes, then the wipes can be used, but the solvent evaporates and the wipes dry out
Solution Approach 1:
The bag interior is divided into two separate chambers by a membrane: a storage chamber that remains sealed to preserve solvent moisture, and an access chamber that allows wipe retrieval. This segmentation enables selective access without exposing the entire contents to air, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
A membrane acts as an intermediary barrier between the storage chamber and access chamber. The membrane allows the bag to be opened for access while preventing air from reaching the solvent-impregnated wipes in the storage chamber, thus maintaining cleaning effectiveness while enabling operation.
2Reliability
If the bag remains closed to preserve moisture, then cleaning effectiveness is maintained, but access to wipes is limited
Solution Approach 1:
By segmenting the bag into storage and access chambers, the invention allows the storage chamber to remain closed (preserving moisture and cleaning effectiveness) while providing a separate access chamber for easy wipe retrieval, thus resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The membrane serves as an intermediary that enables access functionality without compromising the sealed environment of the storage chamber. Users can access wipes through the access chamber while the membrane prevents air contamination of the solvent-impregnated wipes.
3Ease of operation
If the entire bag interior is accessible, then ease of use is improved, but solvent evaporation increases
Solution Approach 1:
The invention segments the bag interior so that only the access chamber is exposed to air during use, while the storage chamber containing the solvent-impregnated wipes remains sealed. This prevents solvent evaporation while maintaining ease of access to wipes.
Solution Approach 2:
The membrane acts as an intermediary barrier that separates the air-exposed access chamber from the sealed storage chamber. This allows users to access wipes without exposing the solvent-containing wipes to air, thereby preventing solvent evaporation while maintaining operational ease.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The bag effectively preserves the moisture of the wipes, maintaining their cleaning effectiveness even after repeated use and exposure to air.
Implementation Method 1
a plastic film membrane extending laterally across the bag, wherein the membrane divides a bag interior into a contents storage chamber intermediate the bag closed bottom and the membrane, and an access chamber intermediate the resealable closure and the membrane

AI summary
A package suitable for wipes. The package has a plastic film bag having a front face panel, a back face panel, an openable top and a closed bottom, a first sealing connection between first side edge regions of the respective panels at one side thereof, a second sealing connection between second side edge regions of the respective panels at the other side thereof, a third sealing connection between third edge regions of the respective panels at the bag bottom, a resealable closure integrated with the bag plastic film for sealingly closing the bag at closure regions of the panels near the bag top, and a plastic film membrane extending laterally across the bag. The membrane divides a bag interior into a contents storage chamber intermediate the bag closed bottom and the membrane, and an access chamber intermediate the resealable closure and the membrane.
