Solution Overview

Problem

The use of unauthorized or counterfeit optical fibers with medical laser systems can lead to malfunctions, equipment damage, and potential safety risks during medical procedures, as current systems lack effective authentication methods to ensure compatibility and authenticity.

Innovation Solution

An excimer laser system with an RFID-based authentication mechanism that verifies the authenticity of laser probes by reading data from embedded RFID tags, ensuring only authorized and compatible probes are used, and preventing laser radiation transmission to unauthorized probes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If no authentication mechanism is implemented, then the system is simple and easy to operate, but unauthorized or counterfeit probes can be used leading to malfunctions, equipment damage, and safety risks

Engineering Contradiction:
Improvesystem safetyVSAvoidauthentication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces manual verification methods with an automated RFID-based authentication system. The RFID reader automatically reads unique identifiers from probes, and the control system automatically verifies compatibility, eliminating the need for manual checking and reducing operational complexity despite adding authentication capability

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

Solution Approach 2:

The patent introduces an RFID tag as an intermediary component embedded in the probe and an RFID reader as an intermediary device in the laser unit. These intermediaries facilitate automatic identification and authentication, enabling reliable verification without direct human intervention while maintaining system simplicity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If authentication mechanisms are added to verify probe compatibility, then system reliability and safety are improved, but the device complexity and operational steps increase

Engineering Contradiction:
Improveprobe compatibility verificationVSAvoidoperational simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The authentication system operates autonomously without requiring user intervention. The RFID reader automatically detects and verifies the probe's unique identifier when connected, and the control system automatically determines compatibility and controls laser output accordingly, making the authentication process transparent to the user

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system provides automatic feedback through the user interface indicating whether a probe is authentic and compatible. The control system continuously monitors authentication status and provides real-time feedback by enabling or disabling laser operation based on verification results, simplifying user decision-making

Inventive Principle:
Principle #23Feedback
