Solution Overview

Problem

Existing respiratory gas systems face challenges with the management of additional components such as accessory tubes and sensor leads, which can project into the path of other components or become wound around the respiratory gases tube, increasing complexity and difficulty for clinicians.

Innovation Solution

The introduction of a connector assembly that includes a connector elbow and port connector, allowing for a secure and adjustable connection between accessory tubes or sensor leads and the respiratory gases tube, with features like barbed or frictional connections, and rotational alignment mechanisms to maintain alignment and prevent rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If accessory tubes and sensor leads are connected to respiratory gases tube, then monitoring and therapeutic capabilities are improved, but the tubes can project into the path of other components or become wound around the respiratory gases tube, increasing complexity and difficulty for clinicians

Engineering Contradiction:
Improvemonitoring and therapeutic capabilitiesVSAvoidmanagement complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connector is divided into distinct segments: a main body portion that attaches to the respiratory gases tube, and an elongate portion that extends outward. This segmentation allows the accessory tubes and sensor leads to be organized in a structured manner, preventing them from projecting chaotically into the path of other components while maintaining their functional capabilities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector design allows accessory tubes and sensor leads to be nested within or alongside the elongate portion in an organized fashion. This nesting arrangement prevents the tubes and leads from becoming wound around the respiratory gases tube, reducing management complexity while preserving the enhanced monitoring and therapeutic functions.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If accessory tubes and sensor leads are connected to respiratory gases tube, then monitoring and therapeutic capabilities are improved, but the risk of interference with other components increases

Engineering Contradiction:
Improvemonitoring and therapeutic capabilitiesVSAvoidinterference risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The connector extracts the potential interference problem by providing a dedicated elongate portion that extends outward from the main body. This separate structure isolates the accessory tubes and sensor leads from the main respiratory gases tube pathway, preventing them from projecting into the path of other components and reducing the risk of interference while maintaining enhanced functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If connector allows rotation to align central axis, then ease of connection is improved, but connection mechanism must prevent rotation to maintain alignment

Engineering Contradiction:
Improveease of connectionVSAvoidconnection mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connector incorporates a dynamic connection mechanism that transitions from a rotational state during connection to a locked state during operation. The mechanism includes features such as a collar that can rotate during attachment but then locks into place to prevent further rotation, maintaining proper alignment of the central axis while simplifying the connection process.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connection mechanism is designed to perform preliminary rotation alignment automatically during the connection process. As the connector is attached, the collar or similar feature rotates to align the central axes of the connector and the respiratory gases tube, then locks into position. This preliminary action ensures proper alignment without requiring complex manual adjustment procedures.

Inventive Principle:
Principle #10Preliminary action
