Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas sensors require different flow rate ranges for optimal measurement, leading to complex, expensive, and large unified devices due to the need for separate flow rate controllers and pumps for each sensor.
Innovation Solution
A multi-port gas flow rate control apparatus that adjusts gas flow rates by varying the flow resistance in channels through different inner diameters and lengths, allowing gases to be distributed to multiple sensors at varying flow rates from a single inlet, thereby simplifying the device design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate flow rate controllers and pumps are provided for each gas sensor, then each sensor can receive gas at its optimal flow rate, but the unified device becomes complicated, expensive and large
Solution Approach 1:
The patent combines multiple flow rate control functions into a single unified flow rate controller that serves multiple gas sensors. Instead of having separate controllers and pumps for each sensor, one controller manages gas distribution to multiple sensors by adjusting flow rates through different flow channels, thereby reducing device complexity while maintaining optimal measurement performance for each sensor
Solution Approach 2:
The flow rate controller is designed with multi-functionality to handle different gas flow rate requirements for multiple sensors simultaneously. It includes multiple flow channels with adjustable flow resistance that can be independently controlled to provide optimal flow rates to different sensors, making a single device perform the work of multiple separate devices
