Solution Overview

Problem

Current sanitization compliance monitoring systems in healthcare environments do not adequately track the sanitization state of caregivers based on their interactions with patients, leading to potential pathogen transmission.

Innovation Solution

A system comprising wearable badges with color-coded indicators and wireless communication with bed and dispenser beacons to monitor hand hygiene compliance, changing states based on proximity to patients and sanitization events, and a central monitoring unit for real-time data collection and analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a caregiver interacts with multiple patients without frequent handwashing, then productivity is improved, but the risk of pathogen transmission increases and sanitization compliance deteriorates

Engineering Contradiction:

Improvecaregiver efficiencyVSAvoidpathogen transmission risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system continuously monitors caregiver hand hygiene compliance through wireless badges that track interactions with patients and automatically detect when sanitization is needed, providing real-time feedback to caregivers about their compliance status without disrupting their workflow

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system enables automated monitoring and tracking of hand hygiene compliance without requiring manual reporting or intervention by infection control personnel, allowing the system to self-monitor and generate compliance data automatically through wireless communication between badges, beacons, and sanitization dispensers

Inventive Principle:

Principle #25Self-service

2Reliability

If handwashing frequency is increased to improve sanitization compliance, then pathogen transmission is reduced, but productivity and time efficiency deteriorate

Engineering Contradiction:

Improvesanitization complianceVSAvoidcaregiver efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system prompts caregivers to perform handwashing or hand-sanitization before patient contact by detecting when they approach patient areas, ensuring sanitization is done in advance rather than as a reactive measure after potential contamination

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system replaces manual tracking and monitoring of hand hygiene compliance with automated wireless detection technology, using RFID or similar wireless communication to automatically track caregiver movements and interactions without requiring physical logs or manual reporting

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If manual monitoring of hand hygiene is used, then system complexity is reduced, but measurement precision and compliance tracking accuracy deteriorate

Engineering Contradiction:

Improvesystem simplicityVSAvoidcompliance tracking accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The system uses wireless badges worn by caregivers and beacon devices placed in patient areas as intermediaries to automatically detect and record interactions, eliminating the need for manual monitoring while providing precise tracking of compliance events through wireless communication

Inventive Principle:

Principle #24Intermediary (Mediator)

4Measurement precision

If real-time monitoring is implemented to improve compliance tracking, then measurement precision is improved, but device complexity and cost increase

Engineering Contradiction:

Improvecompliance monitoring accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The wireless badges serve multiple functions including tracking caregiver identity, monitoring hand hygiene compliance, detecting patient interactions, and providing real-time alerts, while the beacon devices simultaneously monitor multiple caregivers and provide location tracking, reducing overall system complexity through multi-functional components

Inventive Principle:

Principle #6Universality (Multi-functionality)
