Water-Activated Multi-Functional Wipe with Segmented Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disposable cleaning wipes are wet and pre-loaded with a dilute cleaning composition, leading to a short shelf life, increased weight, and reduced cleaning effectiveness, while also requiring preservatives that negatively impact their ecological profile and human safety.
Innovation Solution
Development of a multi-functional wipe that is substantially dry and water-activated, featuring a substrate with green components and separate cleaning, disinfecting/sanitizing, and fragrance compositions, utilizing natural and renewable ingredients to enhance ecological performance without sacrificing cleaning or disinfecting capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wipes are pre-loaded with a dilute cleaning composition containing high water content, then cleaning effectiveness is improved, but shelf life is reduced due to fiber integrity weakening
Solution Approach 1:
The wipe is divided into distinct functional zones: a first section impregnated with cleaning composition and a second section impregnated with disinfecting/sanitizing composition. This segmentation allows each section to perform its specific function optimally while maintaining overall wipe integrity during storage.
Solution Approach 2:
The cleaning and disinfecting compositions are formulated with controlled water content and viscosity parameters to prevent excessive moisture that would weaken fibers during storage, while still providing effective cleaning performance when applied to surfaces.
2Reliability
If conventional wipes are pre-loaded with aqueous cleaning composition, then cleaning performance is enhanced, but weight increases adversely affecting transportation and handling
Solution Approach 1:
The cleaning composition is formulated with optimized concentration and viscosity parameters to achieve effective cleaning performance with reduced water content, thereby decreasing the overall weight of the pre-loaded wipe while maintaining cleaning efficacy.
3Reliability
If conventional wipes use high water content cleaning composition, then cleaning ability is improved, but the wipe can only clean limited surface areas before effectiveness decreases
Solution Approach 1:
The wipe is segmented into multiple functional sections, each impregnated with cleaning or disinfecting composition. This allows a single wipe to cover and treat multiple surface areas sequentially, increasing overall productivity and reducing the number of wipes needed per cleaning task.
Solution Approach 2:
The wipe is designed with multi-functionality by incorporating both cleaning and disinfecting/sanitizing sections, allowing it to perform multiple cleaning tasks in one application, thereby increasing the effective surface area coverage per wipe.
4Duration of action of stationary object
If conventional wipes include preservatives to maintain stability, then shelf life is extended, but manufacturing cost increases and ecological profile is adversely affected
Solution Approach 1:
The wipe is designed as a disposable product with sufficient shelf life for distribution and use without requiring long-term preservation. This allows the use of simpler, more eco-friendly materials and formulations that would not be suitable for long-term storage with preservatives.
Solution Approach 2:
The cleaning and disinfecting compositions are formulated with pH, water activity, and other parameters optimized for stability during typical storage conditions without requiring synthetic preservatives, thereby extending shelf life while maintaining an eco-friendly profile.
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 dry, water-activated wipe improves handling and storage, extends cleaning surface area coverage, reduces material consumption, and maintains ecological friendliness by using natural ingredients, providing effective cleaning, disinfecting, and fragrance delivery while minimizing environmental impact.
Implementation Method 1
The cleaning composition may include one or more green surfactants as cleaning agents
Implementation Method 2
The substrate may include one or more green components and optionally one or more green fillers
Implementation Method 3
naturally occurring essential oils and colloidal silver are both effective disinfecting/sanitizing agents with good antimicrobial activity
Implementation Method 4
Compositions for controlled release of active substances have been developed to allow prolonged release of a fragrance or insecticide into the air
Implementation Method 5
fragrance or insecticide compositions in the form of single-phase solution have been developed to allow prolonged release of a fragrance or insecticide into the air

AI summary
Multi-functional wipes with desirable ecological profiles and improved performances are disclosed. The wipes may include a substrate and a cleaning composition, a disinfecting/sanitizing composition, and an optional fragrance composition releasably associated with the substrate. The compositions may be separated from one another and may be impregnated in or coated on distinct sections of the substrate. Unlike “wet” wipes preloaded with a dilute cleaning liquid, the disclosed wipes may be substantially dry and water-activated just prior to its application on a target surface.
