Meteorological Sensor Calibration via Single Motor Conical Scan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conical scan techniques for meteorological data calibration require two motors, leading to increased loads and costs, while whisk broom techniques cause spatial distortion due to angle differences between sensors and scanned trajectories.
Innovation Solution
A meteorological observation apparatus using a cylinder-shaped body with guiding members and a single motor to move a coupling part along specific routes, allowing a meteorological sensor to measure data in various atmospheric layers without spatial distortion, utilizing a single motor for calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conical scan technique is used for meteorological observation, then spatial distortion is eliminated, but two motors are required which increases load and cost
Solution Approach 1:
The patent combines the functions of two separate motors into a single motor system. The first motor performs both the conical scanning motion and the calibration motion that would traditionally require a second motor, thereby reducing device complexity while maintaining measurement precision through the integrated guiding member mechanism
Solution Approach 2:
The single motor is designed to perform multiple functions: it enables both the conical scanning operation for data collection and the calibration operation by working in conjunction with the guiding members. This multi-functionality eliminates the need for separate calibration motors while preserving spatial accuracy
2Device complexity
If whisk broom technique is used for meteorological observation, then only one motor is required, but spatial distortion occurs due to angle difference between sensor and scanned trajectory
Solution Approach 1:
The patent employs conical scanning motion where the sensor moves along a curved conical path rather than a straight line. This curved trajectory, controlled by the guiding members and single motor, eliminates spatial distortion while maintaining device simplicity, as the conical path naturally compensates for angle differences between sensor and trajectory
3Measurement precision
If two motors are adopted for conical scan calibration, then meteorological data can be calibrated without spatial distortion, but apparatus load and cost increase
Solution Approach 1:
The patent merges the calibration function into the primary motor's operation by using the guiding members to enable the motor to perform both scanning and calibration motions. This reduces apparatus load by eliminating the second motor while maintaining data calibration accuracy through the integrated mechanism
