Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate air-conducting components are used to connect the breathing air source to the patient interface, then the system provides functional flexibility, but the number of components increases and assembly complexity increases

Engineering Contradiction:
Improvefunctional flexibilityVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the air-conducting connector and the temperature sensor connector into a single integrated connector assembly. The sensor receptacle is integrally molded into the connector housing, allowing both air delivery and temperature sensing functions to be performed through one unified component rather than requiring separate connectors to be plugged together.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated connector serves multiple functions simultaneously: it conducts breathing air from the tubing to the patient interface, provides a receptacle for the temperature sensor, and includes electrical contact pins for sensor signal transmission. This multi-functional design eliminates the need for separate dedicated connectors for each function.

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

2Reliability

If a separate sensor connector is used to connect the temperature sensor to the patient interface, then the sensor can be securely mounted, but an additional component is required increasing assembly steps

Engineering Contradiction:
Improvesensor mounting securityVSAvoidassembly steps
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sensor receptacle is integrally molded into the connector housing as a unified structure. The locking section and contact pins are formed as integral parts of the same housing that also provides the air-conducting function, eliminating the need for a separate sensor connector while maintaining secure sensor mounting.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If the sensor receptacle is integrally molded into the connector housing, then manufacturing is simplified, but the sensor must be precisely positioned during insertion

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidsensor positioning precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The sensor guide component is designed to guide the temperature sensor into the correct position within the sensor receptacle during insertion. The guide component includes features that align and position the sensor before it engages with the locking section, ensuring precise positioning is achieved automatically during the assembly process rather than requiring manual adjustment.

Inventive Principle:
Principle #10Preliminary action

AI summary

A component (1) for a patient ventilation system has a breathing air tube section (3) for conveying ventilation air from a ventilation source to a patient. A connector (8) connected to the breathing air tube section (3) serves to connect the breathing air tube section (3) to another component of the patient ventilation system that also carries the ventilation air. An air supply connector component (9) of the connector (8) forms an integral part of the breathing air tube section (3). The connector (8) has a sensor receptacle (19) for inserting a temperature sensor (20) into the air supply connector component (9). The temperature sensor (20) serves to measure the temperature of the ventilation air.A temperature sensor device (2) for insertion into the sensor receptacle (19) of the assembly (1) has a support body (23), the temperature sensor (20) projecting beyond the support body (23), and a grip section (26) for sensing a section of the support body (23) facing away from the temperature sensor (20). This results in an assembly and a pluggable temperature sensor device for a patient ventilation system, thereby reducing the number of air-conducting components of the patient ventilation system that need to be connected.
