Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hygiene compliance surveillance systems are implemented to track cleaning efficacy, then cleaning compliance and pathogen transmission prevention are improved, but device complexity and implementation cost increase

Engineering Contradiction:

Improvecleaning complianceVSAvoidsurveillance system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The cleaning worker wears a wearable computing device that automatically detects cleaning actions through sensors (accelerometer, gyroscope) and validates compliance without requiring external monitoring. The system self-evaluates cleaning efficacy based on pre-defined protocols and provides real-time feedback, eliminating the need for complex external surveillance infrastructure.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual inspection and verification of cleaning compliance is replaced by an automated electronic system. The wearable device uses sensors to detect cleaning motions, process data locally, and provide validation, substituting the mechanical/manual verification process with an automated electronic solution that reduces overall system complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual inspection of cleaning compliance is performed, then monitoring is possible, but productivity of cleaning workers is reduced due to time consumption

Engineering Contradiction:

Solution Approach 1:

The cleaning worker performs self-monitoring and self-validation of cleaning compliance using the wearable device. The system automatically detects cleaning actions, compares them against protocols, and provides immediate feedback without requiring separate inspection personnel, thereby maintaining high productivity while ensuring compliance monitoring.

Inventive Principle:

AI summary

A wearable computing device may be used to track the efficacy of one or more cleaning actions performed. The device can include one or more sensors that detect and measure motion associated with a cleaning event. In different examples, the movement data generated by the device can be compared to reference movement data to determine if the individual has cleaned all the objects they were expected to clean and/or if the individual has cleaned a given object sufficiently well. As another example, the movement data generated by the device can be analyzed to distinguish cleaning and non-cleaning movement actions as well as to distinguish different types of cleaning actions during cleaning movement. The quality of each cleaning action can be evaluated. In any configuration, the device may perform an operation in response to determining that ineffective cleaning is being performed, causing corrected cleaning action to be performed.
