Sponge Compression Cleaning Assembly for Chemical-Free Decontamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for disinfecting sponges are ineffective and pose health risks due to the use of hazardous chemicals, and there is a lack of regulation for soft, porous materials like sponges, which are prone to microbial contamination.
Innovation Solution
A device comprising a vertically-oriented carrier assembly that compresses and immerses a sponge in a cleaning solution, allowing it to absorb and expel the solution, effectively decontaminating it while removing foreign particles, using a base unit with a guide-track system and detent for easy operation and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sponges are disinfected using current methods (bleach, microwaves, aerosols), then microbial contamination is reduced, but health risks increase due to hazardous fumes and toxic chemicals
Solution Approach 1:
The patent extracts the harmful chemicals from the disinfection process by using a mechanical compression and rinsing system instead of chemical agents. The device mechanically removes contaminants through compression and rinsing with clean water, eliminating the need for bleach, aerosols, or other toxic disinfectants that create hazardous fumes.
Solution Approach 2:
The patent replaces chemical and thermal disinfection methods with a mechanical system. The device uses manual compression forces to expel contaminants from the sponge and mechanical rinsing to remove particles, substituting the harmful chemical and microwave-based approaches with a safe mechanical process.
2Reliability
If sponges are compressed and immersed in cleaning solution, then microbial contamination is reduced and foreign particles are removed, but device complexity increases
Solution Approach 1:
The patent divides the device into distinct functional segments: a base unit for holding cleaning solution, a carrier assembly for holding the sponge, and perforated carrier elements for fluid penetration. This segmentation allows each component to perform its specific function efficiently while maintaining overall system simplicity.
Solution Approach 2:
The patent introduces a cleaning solution as an intermediary medium between the user and the sponge. The solution facilitates the removal of contaminants by allowing the sponge to absorb and expel it during compression cycles, providing a safe and effective decontamination mechanism without direct contact with harsh chemicals.
3Reliability
If sponges are pre-infused with disinfectant, then disinfection is enhanced, but toxicity increases due to chemical residues
Solution Approach 1:
The patent employs disposable paper towels or single-use cleaning elements that are discarded after one use, eliminating the need for reusing chemical-infused sponges. This approach ensures that no toxic residues remain on reusable surfaces, as each cleaning element is used once and then disposed of safely.
Solution Approach 2:
The patent extracts harmful chemical residues from the cleaning process by using plain water or mild cleaning solutions instead of pre-infused disinfectants. The mechanical compression and rinsing system removes contaminants without leaving toxic chemical residues on the sponge or surrounding surfaces.
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 device provides a safe, effective, and economical means to decontaminate sponges, reducing microbial contamination without exposing users to hazardous fumes or toxic chemicals, and can be easily manufactured and maintained.
Implementation Method 1
the sponge expands and imbibes the solution
Implementation Method 2
Compression force is then re-imposed on the sponge, squeezing out much of the imbibed solution and leftover particles

AI summary
A device for cleaning and deodorizing a sponge and a method of using the device. The device includes a carrier assembly that travels along a guide-track system and is lowered into a base unit large enough to hold a bath of cleaning solution that would engulf the sponge. The carrier assembly is used to compress, decompress, and recompress the sponge, which in turn absorbs a cleaning solution and expels the cleaning solution along with foreign matter.
