Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid flow sensing apparatuses have limitations in terms of compactness, flexibility, and accuracy, as their sensitivity is often dependent on the physical dimensions of components like laminators, which restricts their adaptability to different fluids and flow ranges.
Innovation Solution
The proposed fluid flow sensing apparatus incorporates a microcalorimetry sensor with a controlling means that allows for direct adjustment of the sensor's sensitivity based on the properties of the fluid, such as type, density, or specific heat capacity, independent of mechanical variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sensitivity of the sensor is dependent on the physical dimensions of components like laminators, then the device structure is simple, but the adaptability to different fluids and flow ranges is limited
Solution Approach 1:
The patent replaces the mechanical adjustment method (changing physical dimensions of laminators) with an electrical/control-based method (adjusting sensitivity through controlling means). The microcalorimetry sensor's sensitivity is now adjusted by controlling the heating element power or signal processing parameters rather than by mechanical changes to component dimensions, thereby improving adaptability without significantly increasing device complexity
Solution Approach 2:
The patent changes the sensitivity parameter of the sensor through the controlling means by adjusting electrical parameters (heating power, measurement parameters) rather than physical dimensions. This allows dynamic adjustment of sensitivity to match different fluid properties and flow ranges, resolving the contradiction between adaptability and device complexity
2Measurement precision
If the sensitivity is adjusted by changing physical dimensions of laminators, then the device is easier to manufacture, but the accuracy for a wider range of applications is reduced
Solution Approach 1:
The patent introduces dynamic adjustability to the sensor sensitivity through the controlling means. Instead of fixed sensitivity determined by static physical dimensions, the sensitivity can be dynamically adjusted via electrical control to optimize measurement precision for different applications, while the basic device structure remains simple and easy to manufacture
Solution Approach 2:
The patent makes the sensor system universal by enabling it to accurately measure different fluids and flow ranges through software/control-based sensitivity adjustment rather than requiring different physical configurations. The same hardware platform can serve multiple applications by changing control parameters, improving accuracy across applications without complicating manufacturing
3Volume of moving object
If a compact design is implemented, then the device size is reduced, but the flow range may be limited
Solution Approach 1:
The patent uses electrical/control-based sensitivity adjustment instead of mechanical scaling. This allows a compact sensor design to maintain or extend its measurement range by adjusting control parameters rather than requiring larger physical dimensions, thereby achieving both compactness and extended flow range adaptability
