Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional manual airflow measurement methods are used, then measurement capability is achieved, but time consumption and labor effort increase significantly
Solution Approach 1:
The measurement system is divided into multiple discrete airflow grids that can be independently positioned and measured. Each grid measures airflow at specific locations, and multiple grids work simultaneously to cover large areas, eliminating the need for sequential manual measurement and reducing total time consumption.
Solution Approach 2:
The patent replaces manual mechanical measurement processes with an automated sensor-based system. Airflow sensors automatically detect and record airflow parameters without requiring manual intervention, eliminating the need for technicians to physically move between measurement points and reducing both time consumption and labor effort.
2Productivity
If traditional sequential measurement approach is used, then complete system coverage is achieved, but productivity decreases due to extensive movement and iterative adjustments
Solution Approach 1:
The system segments the measurement task into multiple simultaneous measurements across different locations using multiple airflow grids. This allows complete system coverage to be achieved in parallel rather than sequentially, dramatically increasing measurement speed while maintaining accuracy through coordinated multi-point data collection.
Solution Approach 2:
The system incorporates real-time feedback mechanisms where airflow sensor data is immediately processed and used to identify areas requiring adjustment. This eliminates iterative guesswork and manual adjustments, allowing the system to achieve both high productivity and reliable measurement accuracy by continuously monitoring and responding to actual airflow conditions.
3Area of stationary object
If multiple discrete measurement points are used to cover large areas, then measurement coverage is improved, but device complexity and setup time increase
Solution Approach 1:
Multiple airflow grids are merged into a coordinated measurement system that functions as a unified array. The grids are positioned to cover large areas simultaneously, and their data is integrated to provide comprehensive system-wide airflow assessment, achieving extensive coverage without proportionally increasing operational complexity.
Solution Approach 2:
The airflow measurement system is designed with universal, standardized components that can be deployed in various configurations to measure different types of HVAC systems. The same basic measurement principles and equipment are used across diverse applications, reducing the need for specialized procedures and simplifying system configuration regardless of the measurement coverage area required.

AI summary
The present disclosure is related to a modular airflow sensor array. The modular airflow sensor array that includes a set of airflow grids that each have one or more airflow passages along an extension that extends from the central point of the airflow grid. The airflow grids can be coupled to a measurement device that receive airflow from the extensions of the airflow grid. The extensions can have a lug at the end opposite of the central point. The lug allows for the airflow grid to be coupled to various connectors that can include a two-way connector or a four-way connector. The two-way connector can couple to a support assembly that allows for the airflow grids to secured and connected in a modular manner. The support assembly can be sized to fit the area to be measured, and then the desired number of airflow grids coupled to the frame.
