Cleaning article comprising multiple sheets and methods thereof
Solution Overview
Problem
Thick blocks of melamine-formaldehyde foam used for cleaning are difficult to manipulate, fit into tight spaces, and retain stains, while thinner sheets are prone to loss, damage, and improper storage, leading to inefficient use and waste.
Innovation Solution
A cleaning article comprising multiple sheets of melamine-formaldehyde foam, each with five sides, including at least one attachment side with discontinuous adhesive, allowing removability and attachment to a cleaning article, which also includes a cover for protection and structural reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thick blocks of melamine-formaldehyde foam are used, then cleaning effectiveness is improved, but ease of operation deteriorates due to difficulty in manipulation and fitting into tight spaces
Solution Approach 1:
The thick block of melamine-formaldehyde foam is divided into multiple thinner sheets, allowing users to select appropriate thickness for different cleaning tasks. This segmentation enables both thick sheets for heavy-duty cleaning and thin sheets for tight spaces, resolving the contradiction between cleaning effectiveness and ease of manipulation.
2Reliability
If thick blocks of melamine-formaldehyde foam are used, then cleaning effectiveness is improved, but loss of substance worsens due to retention of soils and stains on the foam surface
Solution Approach 1:
Dividing the foam into multiple thin sheets allows users to discard only the soiled surface sheet while retaining the clean underlying sheets. This eliminates the problem of stain retention on thick foam, as each thin sheet can be independently replaced without wasting the entire thick block.
3Ease of operation
If thinner sheets of melamine-formaldehyde foam are used, then ease of operation is improved, but reliability worsens due to being loose and difficult to store
Solution Approach 1:
Multiple thin sheets are combined into a single integrated cleaning article with a common core structure. This merging provides storage stability and prevents loss, while the individual sheets remain easily removable and manipulable for cleaning tasks.
4Ease of operation
If thinner sheets of melamine-formaldehyde foam are used, then ease of operation is improved, but loss of substance worsens due to being easily lost, dirtied, torn, and crumpled
Solution Approach 1:
Multiple thin sheets are merged into a single protected unit with a common core, preventing individual sheets from being lost, dirtied, or damaged before use. The protective structure maintains sheet integrity while allowing easy removal for cleaning applications.
Solution Approach 2:
The cleaning article structure provides protective cushioning around each thin sheet before use, preventing them from being easily lost, dirtied, torn, or crumpled during storage and handling. This prior protection eliminates the waste associated with damaged thin sheets.
5Reliability
If sheets are bound tightly to prevent loss, then reliability is improved, but ease of operation worsens due to difficulty in removing sheets without tearing
Solution Approach 1:
The adhesive binding is applied discontinuously at specific locations rather than uniformly across the entire sheet. This local quality approach provides sufficient binding strength for storage stability while leaving margins and edges free for easy tear-free removal during use.
