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

VSEngineering 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

Engineering Contradiction:
Improveease of openingVSAvoidstability against accidental rupture
Core Design Contradiction:
Ease of operationVSReliability

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
ImprovesafetyVSAvoidcontrol of chemical agent amount
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

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

Engineering Contradiction:
Improvereadiness for useVSAvoidwiper quality
Core Design Contradiction:
ProductivityVSReliability

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.

Inventive Principle:
Principle #1Segmentation
