Wiper kit for cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wiper kits for cleaning in clean rooms face safety issues and inefficiencies due to accidental discharge of volatile chemical agents and contamination of wiper fibers, with existing solutions prone to rupture under physical impact or inefficient cleaning liquid distribution.
Innovation Solution
A wiper kit design featuring an outer bag with an inner bag containing a cleaning liquid, an opening member connected to the inner bag, and a grip that allows controlled rupture of the inner bag along a cutoff line when pulled, ensuring precise and safe discharge of the cleaning liquid onto the wiper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inner container is made to rupture easily under hand pressure, then the cleaning liquid can be discharged to the wiper, but the inner container may be ruptured due to strong physical impact applied from the outside when the outer container is handled, so that the cleaning liquid is discharged to the wiper unwillingly
Solution Approach 1:
The inner container is segmented into different structural zones: a thick-walled body portion for stability and a thin-walled rupture portion for controlled opening. This segmentation allows the container to resist external impact while enabling easy opening at the designated rupture line when hand pressure is applied.
Solution Approach 2:
The inner container is pre-formed with a weakened rupture line during manufacturing, creating a predetermined opening path. This preliminary action ensures that when hand pressure is applied, the container opens cleanly at the intended location rather than rupturing unpredictably, while the overall structural integrity remains intact to prevent accidental opening.
2Reliability
If a conventional wiper is packaged with cleaning liquid in a separate container, then the wiper can be kept clean, but it causes safety accidents while discharging dangerous volatile chemical agents and it is not easy for the operator to control a proper amount of the chemical agent
Solution Approach 1:
The cleaning liquid container and wiper are merged into a single integrated package where the liquid is contained within the inner container that is placed inside the outer container holding the wiper. This merging eliminates the need for separate handling of chemical agents, improving safety while maintaining control over the amount of liquid applied to the wiper.
Solution Approach 2:
The inner container is designed as a disposable component that is ruptured during use to discharge the cleaning liquid. This disposable approach eliminates the need for refilling or resetting, ensuring that the exact amount of liquid is applied once and the package is discarded, improving both safety and operational control.
3Productivity
If the cleaning liquid is applied to the wiper in advance in the container, then the wiper is ready to use, but fibers used as a material of the wiper are contaminated or damaged as the cleaning liquid is in contact with the wiper in the container for long time
Solution Approach 1:
The package is segmented into two separate compartments: the outer container holding the wiper and the inner container holding the cleaning liquid. This segmentation prevents contact between the liquid and wiper fibers during storage and transport, maintaining wiper quality while enabling quick activation by simply rupturing the inner container when needed.

AI summary
Disclosed is a wiper kit for cleaning, which includes an outer bag (100) having an inner space accommodating a wiper (1); an inner bag (101) provided at one inner side of the outer bag and hermetically containing a cleaning liquid (2) therein; and an opening member (103) connected to the inner bag and extending toward an outlet of the outer bag, wherein the opening member is connected to the inner bag so that the inner bag is ruptured by pulling the opening member, wherein when the inner bag is ruptured, the cleaning liquid is discharged and applied to the wiper inside the outer bag, wherein a cutoff line (107) is formed at the inner bag, and wherein when the opening member is pulled, the inner bag is ruptured along the cutoff line.
