Dry Reusable Cleaning Substrate for Precise Wet Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning methods using washable substrates are inefficient in substrate utilization and prone to microbial contamination, and require on-site preparation of cleaning solutions, leading to misdosage and unsatisfactory cleaning results.
Innovation Solution
A reusable substrate is loaded with a cleaning composition, dried, and stored in a dry state for transport to the cleaning location, where it is wetted for use, allowing for efficient reuse and minimizing substrate waste and microbial contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If substrates are delivered in a wet state with cleaning composition, then cleaning composition is available for use, but substrates are prone to microbial contamination and require special storage precautions
Solution Approach 1:
The substrate is delivered in a dry state rather than wet, fundamentally changing the moisture parameter to eliminate microbial growth conditions while preserving cleaning composition through encapsulation or binding mechanisms that activate upon contact with water during use
2Adaptability or versatility
If cleaning liquor is prepared on-site by adding cleaning composition to water, then substrates can be used as reusable, but misdosage occurs leading to unsatisfactory cleaning results
Solution Approach 1:
The cleaning composition is pre-applied to the substrate at the manufacturer's facility in precise, controlled amounts, eliminating on-site dosing operations. The substrate arrives ready-to-use with the exact required concentration, preventing both under-dosing and over-dosing that occur during manual preparation
Solution Approach 2:
The substrate itself serves as the delivery vehicle for the cleaning composition, carrying the active ingredients directly to the cleaning surface without requiring separate water mixing or dosing equipment, thereby ensuring consistent application
3Productivity
If substrates are made reusable and washable, then substrate efficiency increases, but they require washing and reloading operations
Solution Approach 1:
The substrate is designed as a single-use, disposable item that is discarded after one cleaning cycle. This eliminates the complexity of washing and reloading operations entirely, while the low cost of the disposable substrate makes the approach economically viable compared to reusable systems
