Solution Overview
Problem
Current wind speed measurement technologies cannot effectively measure two-dimensional wind speed and wind direction simultaneously, leading to poor user experience.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional wind speed measurement methods (hotwire, rotation, ultrasonic, pressure difference) are used, then wind speed measurement is achieved, but wind direction cannot be measured directly
Solution Approach 1:
The wind measurement function is segmented into two independent probe assemblies: X-direction probe assembly for measuring X-axis wind speed components, and Y-direction probe assembly for measuring Y-axis wind speed components. Each assembly contains probes oriented in specific directions, allowing separate measurement of wind speed in each cardinal direction, thereby enabling wind direction determination through component analysis.
Solution Approach 2:
The measurement capability is extended from one-dimensional (single direction wind speed) to two-dimensional by adding probe assemblies in perpendicular directions. The X-direction probe assembly measures horizontal wind components while the Y-direction probe assembly measures vertical or orthogonal components, creating a two-dimensional measurement space that enables full wind vector characterization including direction.
2Measurement precision
If multiple probe assemblies are added to measure two-dimensional wind speed and direction, then measurement capability is improved, but device complexity increases
Solution Approach 1:
Multiple functional probe assemblies (X-direction and Y-direction) are merged into a single integrated sensor device with a unified housing structure. The probe assemblies are positioned perpendicular to each other within the same device body, sharing common mounting structures and electrical connections, thereby reducing overall system complexity compared to separate independent sensors.
Solution Approach 2:
Each probe assembly is designed with multi-functionality: the X-direction probe assembly not only measures X-axis wind speed but also contributes to determining wind direction, while the Y-direction probe assembly similarly provides both wind speed measurement and directional information. This universal design reduces the need for separate specialized sensors for different measurement parameters.
