Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional air measurement devices are used, then device simplicity is maintained, but measurement precision and capability to measure multiple parameters simultaneously deteriorates
Solution Approach 1:
The patent combines multiple measurement functions (ultrasonic anemometer for air speed in two perpendicular directions, temperature sensor, and humidity sensor) into a single handheld device. This merging of previously separate measurement instruments enables simultaneous multi-parameter measurement while maintaining practical device portability and usability.
Solution Approach 2:
The handheld device is designed as a universal measurement tool that can measure multiple air quality parameters (air speed, temperature, humidity) and provide real-time data processing. The device serves multiple measurement needs that previously required separate specialized instruments, making it adaptable to various critical process environment monitoring requirements.
2Adaptability or versatility
If existing air measurement devices are used, then device operation simplicity is maintained, but the ability to measure air flow in multiple directions simultaneously deteriorates
Solution Approach 1:
The device integrates two ultrasonic anemometer sensors oriented in perpendicular directions within a single handheld unit, enabling simultaneous measurement of air flow in multiple directions. This combination eliminates the need for operators to manually reposition separate instruments, maintaining ease of operation while dramatically increasing measurement versatility.
3Reliability
If comprehensive air quality monitoring is implemented, then air quality control improves, but data processing complexity increases
Solution Approach 1:
The device incorporates real-time data processing and feedback mechanisms that immediately analyze measurements from the ultrasonic anemometer, temperature sensor, and humidity sensor. This continuous feedback loop enables reliable air quality control by providing instant information about environmental conditions, allowing for timely adjustments while managing data processing through integrated computational algorithms.
