Solution Overview

Problem

Medical facilities face significant oxygen waste due to the rapid connection and disconnection of oxygen tubing using Christmas tree connectors, leading to prolonged oxygen flow without proper shut-off and requiring manual adjustment of oxygen flow rates upon patient transfer.

Innovation Solution

A quick-connect assembly with a female coupling and male insert, featuring a biased plunger and catch device, which automatically shuts off oxygen flow when disconnected and reinstates the previous flow rate upon reconnection, eliminating the need for manual adjustments and reducing waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If Christmas tree connectors are used for rapid connection and disconnection of oxygen tubing, then connection speed is improved, but oxygen waste increases due to prolonged flow after disconnection

Engineering Contradiction:
Improveconnection speedVSAvoidoxygen waste
Core Design Contradiction:
SpeedVSLoss of energy

Solution Approach 1:

The quick-connect assembly performs the shut-off action automatically at the moment of disconnection. The biased plunger is pre-positioned to block the bore, and upon disconnection, it immediately returns to the blocked position without requiring manual intervention, thus preventing oxygen waste before it can occur

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system automatically shuts off oxygen flow upon disconnection and automatically restores flow upon reconnection without requiring manual operation. The biased plunger self-actuates based on the presence or absence of the connected tubing, making the system self-regulating and eliminating human error in flow control

Inventive Principle:
Principle #25Self-service

2Reliability

If manual adjustment of oxygen flow rates is required upon patient transfer, then flow rate control is maintained, but time consumption and operational complexity increase

Engineering Contradiction:
Improveflow rate controlVSAvoidtime for manual adjustment
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The quick-connect assembly automatically maintains the blocked or open state based on connection status, eliminating the need for manual flow rate adjustments during patient transfers. The system self-regulates flow without requiring staff intervention, saving time and reducing operational complexity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention extracts the manual adjustment function from the oxygen delivery system by automating flow control through the biased plunger mechanism. This separates the flow control function from manual operation, allowing the system to automatically adapt to connection and disconnection events

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If oxygen sources are left running after tubing disconnection, then ease of operation is improved, but oxygen waste and safety hazards increase

Engineering Contradiction:
Improveease of operationVSAvoidoxygen waste and safety hazards
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The system automatically shuts off flow upon disconnection without requiring manual intervention, preventing oxygen waste and safety hazards while maintaining ease of operation. The biased plunger self-actuates to block the bore when tubing is removed, eliminating the need for staff to manually turn off oxygen sources

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The biased plunger is pre-positioned to block the bore, and automatically activates to prevent oxygen flow at the moment of disconnection. This preliminary anti-action prevents the harmful effect of wasted oxygen and potential safety hazards before they can occur

Inventive Principle:
Principle #9Preliminary anti-action
