Solution Overview

Problem

Existing cleaning systems require costly measurement technology or manual effort to determine contamination levels, making efficient cleaning of large environments inefficient and costly.

Innovation Solution

A system that uses detection devices to collect usage data on environmental subareas, allowing the computing device to plan and adjust cleaning activities based on actual usage, eliminating unnecessary cleaning and prioritizing high-use areas, thereby optimizing cleaning schedules and reducing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If measurement technology is used to detect contamination levels, then cleaning effectiveness is improved, but system cost increases significantly

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidsystem cost
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces usage data as an intermediary parameter that indirectly indicates contamination levels. Instead of directly measuring contamination with expensive sensors, the system uses detection devices to monitor usage patterns (foot traffic, equipment movement, etc.) which serve as a proxy for contamination risk. This mediator approach resolves the contradiction by providing reliable cleaning decisions without direct contamination measurement.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/physical measurement system (contamination sensors) with an information-based system (usage data collection and analysis). By substituting direct physical measurement with indirect information processing, the system achieves comparable cleaning effectiveness without the high costs and complexity of specialized sensing hardware.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If manual contamination assessment is used, then system cost is reduced, but time consumption and labor requirements increase

Engineering Contradiction:
Improvesystem costVSAvoidtime consumption
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The system implements self-service by automatically collecting, processing, and acting on usage data without human intervention. Detection devices continuously monitor the environment and automatically generate cleaning decisions based on predefined criteria. This eliminates the need for manual assessment while maintaining low system costs, resolving the contradiction between cost and time efficiency.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent establishes a continuous feedback loop where usage data is constantly collected, analyzed, and used to adjust cleaning schedules in real-time. This automated feedback mechanism replaces manual assessment, providing timely cleaning decisions without human labor while keeping system costs low through the use of simple detection devices rather than complex measurement systems.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If cleaning activities are performed based on fixed schedules, then operational simplicity is maintained, but cleaning efficiency decreases

Engineering Contradiction:
Improveoperational simplicityVSAvoidcleaning efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent transforms the static, fixed cleaning schedule into a dynamic system that automatically adapts to changing usage patterns. The cleaning plan is continuously adjusted based on real-time usage data, allowing the system to respond to actual environmental conditions. This dynamic approach maintains operational simplicity through automated decision-making while significantly improving cleaning efficiency by targeting high-usage areas.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the key parameter for scheduling from fixed time intervals to variable usage-based triggers. By monitoring usage data and adjusting cleaning timing and intensity based on actual environmental activity, the system achieves both operational simplicity (through automated rules) and high productivity (by cleaning only when necessary).

Inventive Principle:
Principle #35Parameter changes

4Reliability

If all sub-areas are cleaned regularly, then cleaning completeness is ensured, but resource waste increases

Engineering Contradiction:
Improvecleaning completenessVSAvoidresource waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies local quality by differentiating cleaning requirements across different sub-areas based on their specific usage patterns. Instead of uniform cleaning, the system identifies and targets only those areas with high usage and corresponding contamination risk. This localized approach ensures cleaning completeness for necessary areas while eliminating resource waste in low-usage areas.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system implements partial action by performing cleaning only on sub-areas that require it, rather than cleaning the entire environment uniformly. Based on usage data analysis, the system selectively applies cleaning resources to high-priority areas, achieving sufficient cleaning completeness where needed while avoiding excessive cleaning actions in low-priority areas, thus reducing resource waste.

Inventive Principle:
Principle #16Partial or excessive action
