Solution Overview

Problem

Current cleaning systems lack a systematic approach, leading to inadequate cleaning of surfaces, particularly in healthcare settings, where improper use of cleaning articles can increase the risk of infection transmission due to user error and lack of training.

Innovation Solution

A teaching aid and method that includes a legend portion and a predefined area portion, with sequential numerical indicia and visual indicators, to guide healthcare personnel in a systematic cleaning order, ensuring all surfaces are cleaned efficiently and hygienically, using color-coding and microfiber booklets or cloths to identify specific cleaning areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cleaning articles are used as generic commodity components without training, then ease of operation is improved, but reliability deteriorates due to improper use increasing infection transmission risk

Engineering Contradiction:
Improveease of useVSAvoidinfection transmission risk
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cleaning system is segmented into distinct color-coded cleaning articles (blue for surfaces, green for linens, yellow for floors) with corresponding color-coded markers placed throughout the healthcare facility. This segmentation allows untrained users to easily identify which cleaning article to use for each specific task, maintaining ease of operation while ensuring proper usage through visual cues that prevent cross-contamination and reduce infection transmission risk.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a color-coding system where different colors of cleaning articles correspond to different cleaning zones and purposes. Blue articles for general surfaces, green for linens, yellow for floors, and red for isolation areas. This color-based visual system enables untrained users to quickly and intuitively select the appropriate cleaning article for each task, ensuring proper usage without requiring extensive training while maintaining ease of operation and reducing infection transmission risk through systematic color differentiation.

Inventive Principle:
Principle #32Color changes

2Productivity

If cleaning is performed quickly to meet productivity demands, then productivity is improved, but reliability deteriorates as users fail to adequately clean contact surfaces

Engineering Contradiction:
Improvecleaning speedVSAvoidadequacy of cleaning
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

Markers are pre-placed throughout the healthcare facility at all surfaces that require cleaning, including contact surfaces. These markers serve as a preliminary visual guide that directs users to the exact locations that need cleaning. This preliminary action ensures that even when cleaning is performed quickly to meet productivity demands, users will not miss critical contact surfaces because the markers provide a pre-established visual roadmap of all areas requiring attention.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The color-coded markers provide immediate visual feedback to cleaning personnel about which surfaces have been cleaned and which remain. As users complete cleaning tasks, they can visually confirm progress by observing which markers have been addressed. This feedback mechanism maintains reliability by ensuring adequate cleaning of all contact surfaces even during rapid cleaning operations, as the visual system continuously guides users to未完成 areas without requiring complex checklists or extensive training.

Inventive Principle:
Principle #23Feedback

3Reliability

If a systematic cleaning approach is implemented with teaching aids and sequential indicia, then reliability is improved by ensuring proper cleaning order, but device complexity increases

Engineering Contradiction:
Improvecleaning order accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a color-coded marker system where different colors indicate different cleaning priorities and sequences. For example, red markers may indicate critical contact surfaces that require immediate attention, while other colors indicate subsequent cleaning areas. This color-based coding system provides a systematic approach to ensuring proper cleaning order and reliability without requiring complex documentation, lengthy training programs, or complicated procedures. The visual color-coding inherently communicates the cleaning sequence in an intuitive manner that can be understood by all users regardless of training level.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The system changes the parameter of visual identification by using color-coded markers to indicate cleaning priority, sequence, and area type. Instead of relying on complex written instructions or hierarchical procedures, the system transforms the cleaning guidance into a visual parameter system where color immediately conveys critical information about cleaning order and importance. This parameter change from textual/procedural guidance to visual color-coding maintains reliability by ensuring proper cleaning sequence while dramatically reducing system complexity and making the system accessible to untrained users.

Inventive Principle:
Principle #35Parameter changes

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 (400,600) or microfiber booklets (801,808) in a cleaning package assembly (1300).
