Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning tools lack versatility to clean complex equipment surfaces with varying shapes, such as tubes and corners, and often lead to contamination due to debris creation. Additionally, they may not be compatible with commercial laundering and sterilizing procedures, and reusable tools can accumulate lint in crevasses.
Innovation Solution
A reusable cleaning mitt with an outer high-performance microfiber surface that provides a 4-log reduction in bacteria presence per wipe, configured with corner openings for easy rinsing and a seamless folding edge for effective cleaning of complex surfaces. The mitt is designed to withstand sterilization processes like autoclaving and gamma irradiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional cleaning tools are used, then they can clean flat surfaces, but they cannot effectively clean complex equipment surfaces with varying shapes such as tubes and corners
Solution Approach 1:
The cleaning device uses a flexible mitt made of microfiber material that can conform to complex surfaces. The mitt is designed with a seamless folding edge and corner openings that allow it to adapt to varying surface geometries including tubes and corners, providing versatility without mechanical complexity
Solution Approach 2:
The cleaning mitt is designed to be dynamic and adaptable in shape through its flexible construction. The material allows the mitt to dynamically conform to different surface geometries during cleaning operations, enabling effective cleaning of complex surfaces without requiring complex tool structures
2Productivity
If conventional cleaning tools are used, then they can perform cleaning operations, but they create debris that leads to contamination
Solution Approach 1:
The cleaning mitt is constructed from microfiber material with a porous structure that traps and holds cleaning solution and debris within its fibers. This porous construction allows the material to capture particles and contaminants during cleaning while preventing them from becoming airborne debris, thus maintaining cleaning effectiveness without generating contamination
Solution Approach 2:
The cleaning device uses composite microfiber material that combines different fiber properties to achieve both effective cleaning and minimal debris generation. The composite structure allows the material to effectively capture contaminants while the fiber composition prevents lint and debris shedding during use
3Loss of substance
If reusable cleaning tools are used, then they are environmentally friendly, but they accumulate lint in corners and crevasses
Solution Approach 1:
The design extracts and eliminates corners and crevasses from the mitt structure through the seamless folding edge and corner openings. This geometric modification prevents lint and debris from accumulating in hidden areas, allowing the reusable tool to maintain environmental benefits without the harmful effect of lint accumulation
Solution Approach 2:
The corner openings create segmented zones within the mitt structure that allow debris and lint to be expelled from the material during use. This segmentation prevents accumulation by providing escape paths for captured particles, enabling the reusable tool to function without generating lint contamination
4Ease of operation
If conventional cleaning tools are used, then they can be used for cleaning, but they are not compatible with commercial laundering and sterilizing procedures
Solution Approach 1:
The microfiber material is selected and engineered to withstand extreme parameter changes during commercial laundering and sterilization processes. The material properties are optimized to resist degradation from high temperatures, chemicals, and mechanical agitation, ensuring both laundering compatibility and sterilization resistance
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 cleaning mitt effectively cleans and disinfects complex surfaces with high bacterial reduction efficiency, is environmentally friendly, and compatible with commercial sterilization processes, reducing contamination risks and operational costs.
Implementation Method 1
The outer surface comprises a high performance microfiber that, in terms of cleaning efficacy, is configured to provide a 4-log reduction in bacteria presence per step/wipe as measured by bacterial removal tests. The reduction in bacterial presence is achieved by mechanical and capillary action of the high performance microfiber
