Solution Overview
Problem
Current cleaning systems lack a systematic approach for healthcare settings, leading to inadequate cleaning of contact surfaces and increased risk of infection transmission due to improper use of cleaning articles by untrained personnel.
Innovation Solution
A teaching aid and method that provides a predefined cleaning order for hospital rooms, using visual indicators and sequential numerical indicia on a teaching insert and cleaning cloths to ensure all surfaces are cleaned efficiently and hygienically, reducing the risk of infection transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cleaning articles are used as generic commodity components without training, then cost is reduced, but cleaning effectiveness deteriorates and infection transmission risk increases
Solution Approach 1:
The cleaning cloth is segmented into multiple sections with different functions (absorbent section, less absorbent section, scrub section) to address different cleaning needs in specific sequences, improving cleaning effectiveness without requiring additional training
Solution Approach 2:
The cleaning cloth is pre-configured with numbered sections and cleaning instructions printed directly on it, providing preliminary guidance on the cleaning sequence and method before the user begins, eliminating the need for separate training
2Productivity
If cleaning is performed quickly to meet productivity demands, then productivity increases, but cleaning completeness deteriorates and surfaces are inadequately cleaned
Solution Approach 1:
The cleaning process is segmented into numbered sections (1-8) corresponding to different surfaces or areas, allowing cleaners to systematically move through each area without missing any surfaces, maintaining completeness while improving speed through standardized sequencing
Solution Approach 2:
The cleaning cloth itself provides the instructions through printed numbers and sequences, making the cleaning process self-guiding without requiring external supervision or complex procedures, enabling fast yet complete cleaning
3Reliability
If cleaning instructions are provided through formal training programs, then cleaning quality improves, but time consumption and complexity increase
Solution Approach 1:
The cleaning cloth incorporates printed instructions and numbered sequences directly on its surface, allowing users to learn and follow proper cleaning procedures through self-guidance during the actual cleaning task, eliminating the need for separate formal training programs
Solution Approach 2:
The cleaning instructions and sequence are pre-printed on the cloth itself, providing immediate guidance at the point of use without requiring prior training or memorization, maintaining high cleaning quality while minimizing time investment
4Object-affected harmful factors
If all surfaces are systematically cleaned following a predefined order, then infection transmission risk is reduced, but cleaning time increases
Solution Approach 1:
The cleaning process is divided into 8 numbered sections that guide the cleaner through a logical sequence of surfaces, ensuring all areas are covered systematically to reduce infection risk while maintaining efficient workflow
Solution Approach 2:
The cleaning sequence and instructions are pre-established and printed on the cloth, allowing cleaners to immediately follow a proven infection-control protocol without time-consuming planning or decision-making during the cleaning process

AI summary
A visual teaching aid (100) assists teaching a cleaning order for a predefined area (106). The visual teaching aid can include a legend portion (103) defining a plurality of portions (105) of the predefined area, while a predefined area portion (104) pictorially illustrates the plurality of portions. The legend portion can define a plurality of sequential numerical indicia (107) indicating a predefined order in which the plurality of portions should be cleaned. The predefined area portion can include a plurality of visual indicators (110) assigned to the plurality of portions on a one-to-one basis. The visual teaching aid can be included with one or more cleaning cloths (300,500) in a cleaning package assembly (700).
