Solution Overview

Problem

In medical environments, there is a challenge in securely managing access to medical supplies and areas to prevent unauthorized use, misuse, and theft, while also minimizing the spread of infectious diseases and optimizing resource utilization.

Innovation Solution

A tracking and access system that uses a tracking element, detector device, central processing unit, and lock system to monitor and control access based on individual privileges, allowing authorized personnel to access medical supplies and areas while restricting unauthorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If access control measures are implemented to prevent unauthorized access and theft of medical supplies, then security and safety are improved, but device complexity and operational procedures become more complex

Engineering Contradiction:
ImprovesecurityVSAvoidaccess control system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The tracking element serves multiple functions: it acts as both a security authentication device and a personnel tracking device. The same element that identifies authorized personnel for access control also enables continuous tracking throughout the facility, eliminating the need for separate systems and reducing overall complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

A central controller acts as an intermediary that receives signals from tracking elements, determines authorization status, and controls lock mechanisms. This centralized mediation simplifies the system architecture by consolidating decision-making logic in one location rather than requiring complex distributed intelligence

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If tracking elements are used to monitor personnel movement and prevent disease spread, then health safety is improved, but loss of privacy and increased monitoring complexity occur

Engineering Contradiction:
Improvedisease spreadVSAvoidprivacy
Core Design Contradiction:
Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The system processes and stores tracking data locally at the facility level rather than centralizing all information in one location. This distributed approach allows for targeted monitoring to prevent disease spread while maintaining privacy by limiting data access to only what is necessary for public health purposes

Inventive Principle:
Principle #3Local quality

3Loss of substance

If strict access control is implemented to prevent misuse of medical supplies, then resource protection is improved, but productivity and ease of operation deteriorate due to additional authentication steps

Engineering Contradiction:
Improvemedical supply wasteVSAvoidaccess speed
Core Design Contradiction:
Loss of substanceVSProductivity

Solution Approach 1:

Authorization credentials are pre-loaded onto tracking elements before personnel enter the facility. This preliminary authentication setup allows for rapid access decisions at control points without requiring time-consuming verification procedures, thus maintaining productivity while preventing supply misuse

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The tracking element automatically communicates authorization status to the control system without requiring manual verification by security personnel. This self-service authentication mechanism speeds up access while maintaining security, as the system independently verifies credentials and controls access based on pre-established authorization levels

Inventive Principle:
Principle #25Self-service

AI summary

An apparatus may include a controller that may include one or more processors, and memory storing executable instructions that, when executed by the one or more processors, may cause the one or more processors to perform operations. The operations may include receiving key fob data from a reader. The key fob data may include ID information of a user. The operations may further include determining authorization privileges associated with the received ID information of the user, and controlling a lock system of a gas flow valve in response to the determination of the authorization privileges associated with the received ID information of the user.
