Adjustable Resistance Flow Measuring Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow measuring devices struggle to accurately estimate the flow rate of clean gas supplied to containers with varying inflow resistance, as the devices are typically designed for specific containers and fail to account for individual differences in resistance among containers of the same type.
Innovation Solution
A flow measuring device with adjustable resistance members that can be matched to the inflow resistance of different containers, ensuring accurate measurement of clean gas flow rates regardless of variations in container-specific resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a flow measuring device is designed for a specific container type, then the measurement is accurate for that container type, but the measurement accuracy deteriorates when used with containers of different types or individual containers having different inflow resistance
Solution Approach 1:
The flow measuring device incorporates an adjustable resistance member that can dynamically change the inflow resistance value to match different containers. This allows the device to adapt its resistance characteristic dynamically, enabling accurate measurement across multiple container types without requiring multiple fixed-device designs.
Solution Approach 2:
The invention changes the resistance parameter of the flow measuring device by providing adjustable resistance members with different resistance values. This parameter adjustment allows the device to match the inflow resistance characteristics of different containers, thereby maintaining measurement accuracy across various container types.
2Measurement precision
If multiple flow measuring devices are provided for different container types, then measurement accuracy is maintained for each container type, but the device complexity and cost increase
Solution Approach 1:
The flow measuring device is designed with multi-functionality by incorporating an adjustable resistance member that can be set to different resistance values. This single device can thus serve multiple container types that would otherwise require separate dedicated devices, reducing overall system complexity and cost.
Solution Approach 2:
By making the resistance characteristic adjustable rather than fixed, the device becomes dynamic and adaptable to different measurement requirements. This eliminates the need for multiple static devices and allows one device to perform multiple functions across different container types.
3Device complexity
If the inflow resistance of the flow measuring device is fixed, then the device structure is simple, but the measurement accuracy deteriorates for containers with different inflow resistance values
Solution Approach 1:
The resistance member is designed to be adjustable rather than fixed, introducing a dynamic element to the device structure. This allows the resistance value to be changed as needed to match different containers, improving measurement accuracy without requiring completely separate devices for each container type.
Solution Approach 2:
The invention changes the resistance parameter from a fixed value to an adjustable value. This parameter change enables the device to adapt to different container characteristics while maintaining a relatively simple overall structure, avoiding the need for multiple complex device configurations.
