Solution Overview

Problem

Current medical procedures face challenges in accurately authenticating patient information, particularly during transitions between medical facilities and processes, which increases the likelihood of errors due to incorrect patient records and obscured patient portions during procedures.

Innovation Solution

A system that uses machine-readable information printed on garments worn by patients, processed by cameras and processors, to authenticate patient data and ensure correct medical procedures by determining if the procedure steps are properly aligned and authorized, preventing operation of medical equipment if errors are detected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If machine-readable information is used on patient garments, then patient identification accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvepatient identification accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual patient identification methods (visual inspection, paper records) with machine-readable information systems. Cameras capture images of machine-readable codes on patient garments, and processors automatically decode this information to identify patients, eliminating manual verification processes and reducing human error.

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

Solution Approach 2:

The patent uses machine-readable codes as digital copies of patient identification data. Instead of relying on physical patient characteristics or paper records, the system captures and processes digital representations of patient information stored in machine-readable format on garments, enabling accurate and efficient identification.

Inventive Principle:
Principle #26Copying

2Reliability

If multiple process elements are added to verify patient information, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improveprocedure verification reliabilityVSAvoidprocess element complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple verification functions into an integrated system. The camera, processor, and medical equipment control are merged into a cohesive verification system that automatically checks patient identity, procedure appropriateness, and equipment authorization simultaneously, reducing the need for separate verification steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs automatic verification without requiring manual intervention at each step. The processor automatically decodes machine-readable information, compares it with procedure data, and authorizes or prevents equipment operation based on verification results, making the system self- verifying and reducing operational complexity.

Inventive Principle:
Principle #25Self-service

3Reliability

If real-time authentication is implemented, then error reduction is improved, but use of energy increases

Engineering Contradiction:
Improveerror reductionVSAvoidsystem energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements verification at specific periodic points in the medical procedure workflow - before patient identification, before procedure initiation, and before equipment operation. This periodic authentication approach ensures error reduction at critical moments without requiring continuous energy-intensive monitoring throughout the entire procedure.

Inventive Principle:
Principle #19Periodic action
