Solution Overview

Problem

Manual cleaning of electrical connectors for ventricular assist devices and other technologies in contaminant-laden environments is time-consuming and increases the risk of complications, particularly during implantation procedures, due to the need for continuous electrical power and the challenge of maintaining connector cleanliness.

Innovation Solution

A connector cleaning system comprising cleaning and drying chambers with image processing capabilities to automate the cleaning and verification process, using a camera, control circuit, and transmitter to capture and document images of the connectors before and after cleaning, ensuring thorough contamination removal and efficient documentation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual cleaning of electrical connectors is performed during implantation procedures, then connector cleanliness is improved, but procedure time and risk of complications increase

Engineering Contradiction:
Improveconnector cleanlinessVSAvoidprocedure time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The cleaning system is prepared and ready before the connector needs cleaning. The device includes pre-loaded cleaning elements and is positioned near the surgical site, allowing immediate cleaning when contamination occurs without requiring time-consuming manual preparation of cleaning materials

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system enables the connector to be cleaned automatically through mechanical means rather than requiring manual technician intervention. The automated cleaning mechanism performs the cleaning function independently, reducing the need for human operators to manually clean each connector during the procedure

Inventive Principle:
Principle #25Self-service

2Measurement precision

If manual cleaning documentation is performed, then cleaning verification is improved, but surgical team productivity decreases

Engineering Contradiction:
Improvecleaning verificationVSAvoidsurgical team productivity
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The manual documentation process is replaced with an automated imaging and recording system. A camera captures images of the connector before and after cleaning, and a computer automatically documents the results, eliminating the need for technicians to manually record cleaning information while maintaining verification accuracy

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

Solution Approach 2:

Instead of manually documenting cleaning results, the system creates visual copies (images) of the connector state. These images serve as objective documentation of cleaning effectiveness, replacing subjective manual assessment and recording while providing permanent verification records

Inventive Principle:
Principle #26Copying

3Reliability

If multiple implanted connectors are cleaned manually, then all connectors are cleaned, but idle time and procedure cost increase proportionately

Engineering Contradiction:
Improveconnector cleanlinessVSAvoidcleaning system coordination
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cleaning system is designed to handle multiple connector types and sizes with a single device. The system can clean various implanted connectors (such as VAD connectors and other medical device connectors) using the same mechanical cleaning mechanism, eliminating the need for different cleaning tools for each connector type

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