Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If an actuator is added to increase gas flow rate to the gas sensor, then sensing efficiency is improved, but heat is generated that interferes with the gas sensor readings

Engineering Contradiction:

Improvesensing efficiencyVSAvoidheat interference

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The device is divided into separate functional chambers: a first chamber for the actuator and a second chamber for the gas sensor. This segmentation physically isolates the heat-generating actuator from the sensitive gas sensor, allowing the actuator to operate at high speed for efficient gas transport without thermally interfering with the sensor measurements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A partition wall with a gas passage acts as an intermediary structure between the actuator chamber and the gas sensor chamber. This intermediary allows gas to flow from the first chamber to the second chamber while providing thermal isolation, enabling the actuator to drive gas flow without directly heating the sensor environment.

Inventive Principle:

Principle #24Intermediary (Mediator)
