Solution Overview

Problem

Medical procedures requiring multiple catheters often face inefficiencies due to mismatches between the number of catheter sockets and channels, leading to time-consuming unplugging and re-plugging, which disrupts the procedure.

Innovation Solution

A system with a switching unit and circuitry that uses EEPROM devices to store channel information and produce control signals for routing signals, allowing automatic connection and disconnection of catheters, ensuring seamless signal transmission regardless of the number of catheters plugged in.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of catheter sockets is fixed in the console, then the device structure is simple, but it cannot accommodate variable numbers of catheters, leading to unplugging and re-plugging operations

Engineering Contradiction:
Improveadaptability to variable number of cathetersVSAvoidcomplexity of switching unit and routing system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The catheter management system is segmented into multiple independent switching units, each handling a subset of catheter channels. This allows the system to accommodate variable numbers of catheters by activating only the necessary switching units, rather than requiring a fixed large array of sockets.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A switching unit acts as an intermediary between the catheters and the console, providing flexible routing of catheter channels to console sockets. This mediator enables dynamic allocation of channel connections without requiring physical reconfiguration of the console itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If manual unplugging and re-plugging of catheters is performed, then the number of available sockets is limited, but this causes time loss and procedural interruptions

Engineering Contradiction:
Improveprocedural efficiency and time utilizationVSAvoidtime for unplugging and re-plugging operations
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The switching unit is pre-configured with multiple catheter sockets and channel routing paths before the procedure begins. This preliminary setup eliminates the need for time-consuming unplugging and re-plugging operations during the procedure, as all necessary connections are already available through the switching matrix.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The switching unit provides dynamic channel routing that can be reconfigured electronically during the procedure without physical intervention. This dynamic capability allows rapid switching between different catheter configurations, maintaining procedural flow and eliminating manual connection changes.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple catheters with multiple channels each are connected, then the signal routing complexity increases, but the console has fixed sockets limiting flexibility

Engineering Contradiction:
Improveflexibility in catheter channel configurationVSAvoidcomplexity of signal routing and channel management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The switching unit is designed as a universal interface that can handle multiple catheter types and channel configurations through a single device. It provides multi-functional capability to route different catheter channels to appropriate console sockets based on the specific procedural requirements, rather than requiring dedicated sockets for each catheter type.

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

Solution Approach 2:

The switching unit adds a dimensional layer of abstraction between the catheters and console, transforming the fixed one-to-one socket relationship into a many-to-many routing matrix. This dimensional change enables flexible channel allocation across multiple catheters without increasing the physical console socket count.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
