Solution Overview

Problem

Existing portable devices with gas detecting modules face challenges in maintaining slim and lightweight designs while ensuring accurate gas detection, as components like processors can interfere with the detection process and generate heat that affects sensor results.

Innovation Solution

A slim-type portable device design featuring a gas detecting module with a carrying plate, compartment body, sensor, and actuator, where the sensor and actuator are separated by a partition plate to prevent heat interference, allowing for one-way gas flow and monitoring, and the actuator is designed to generate a flow of gas that is discharged outside the compartment body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the gas detecting module is made slim and lightweight to meet portable device requirements, then the device portability and slimness are improved, but the accuracy of gas detection may deteriorate due to heat interference from processors and other components

Engineering Contradiction:
Improvethickness of gas detecting moduleVSAvoidgas detection accuracy
Core Design Contradiction:
Length of moving objectVSMeasurement precision

Solution Approach 1:

The gas detecting module is segmented into distinct functional zones: a first compartment housing the sensor and a second compartment housing the actuator, separated by a partition plate. This segmentation isolates the heat-generating actuator from the sensitive sensor, allowing the module to remain slim while maintaining detection accuracy by preventing thermal interference between components.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If components like processors are placed close to the sensor to reduce device size, then the device complexity is reduced, but the detection reliability deteriorates due to heat interference from these components

Engineering Contradiction:
Improvecomponent arrangement simplicityVSAvoiddetection reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The actuator, which generates heat during operation, is extracted from the sensor compartment and placed in a separate second compartment. The partition plate physically extracts the heat source from the detection zone, allowing processors and other heat-generating components to be positioned close to the sensor without compromising detection reliability, thus reducing overall device complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If the gas detecting module is designed with separate compartments for sensor and actuator to prevent heat interference, then the detection precision is improved, but the device complexity increases

Engineering Contradiction:
Improvegas detection precisionVSAvoidmodule structure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The partition plate serves multiple functions simultaneously: it separates the sensor and actuator compartments to prevent heat interference, provides structural support for the slim module design, and guides gas flow from the first to the second compartment. This merging of functions reduces the need for additional components, thereby limiting the increase in device complexity while maintaining detection precision.

Inventive Principle:
Principle #5Merging (Combining)

4Productivity

If the actuator is positioned to generate gas flow through the sensor area, then the gas monitoring efficiency is improved, but the sensor accuracy deteriorates due to heat exposure from the actuator

Engineering Contradiction:
Improvegas monitoring efficiencyVSAvoidsensor accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The actuator is positioned in the second compartment below the partition plate, generating gas flow that moves upward through the partition plate into the first compartment where the sensor is located. This vertical arrangement in another dimension allows the actuator to efficiently drive gas flow past the sensor while the partition plate blocks direct thermal exposure, maintaining both monitoring efficiency and sensor accuracy.

AI summary

A gas detecting module includes a carrying plate, a sensor, a compartment body and an actuator. The carrying plate has a substrate and a gas opening. The compartment body is divided into a first compartment and a second compartment by a partition plate. The first compartment has an opening. The second compartment has an outlet and accommodates the actuator. The bottom of the compartment body has an accommodation recess receiving the carrying plate, whereby the gas opening is aligned with the outlet, and the sensor packaged on the substrate is disposed within the first compartment through the opening. The partition plate has a notch. The gas detecting module is assembled in a slim-type portable device having a casing. The casing has an inlet aligned with the first compartment. As the actuator is actuated, ambient gas is inhaled into the first compartment, and the sensor detects the gas flowing therethrough.
