Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional motion compensation methodologies are used, then wind velocity measurement accuracy is improved, but system complexity increases
Solution Approach 1:
The patent extracts only the essential motion compensation function by using a simplified model that considers only the dominant terms in the wind velocity measurement equation. The complex conventional methodologies that attempt to compensate for all possible error sources are replaced with a focused approach that addresses the primary motion-related errors, thereby reducing system complexity while maintaining adequate measurement accuracy.
Solution Approach 2:
The patent changes the parameters of the motion compensation model by using a simplified mathematical representation that relates wind sensor acceleration directly to wind velocity measurements. This parameter change transforms the complex conventional approach into a more manageable system that requires fewer computational resources and simpler implementation while still providing effective motion compensation.
2Measurement precision
If conventional motion compensation methodologies are used, then wind velocity measurement accuracy is improved, but power consumption increases
Solution Approach 1:
The patent extracts only the critical motion compensation calculations needed to maintain measurement accuracy, eliminating unnecessary computational steps present in conventional methodologies. This extraction reduces the processing power required and consequently lowers energy consumption while still achieving the primary goal of accurate wind velocity measurement in motion.
Solution Approach 2:
The patent applies partial action by implementing motion compensation only for the most significant error sources rather than attempting to compensate for all possible sources of measurement error. This selective approach reduces computational burden and power consumption while maintaining measurement accuracy sufficient for practical applications.
3Measurement precision
If additional sensors and controllers are added to compensate for motion errors, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent makes the wind sensor system multi-functional by enabling it to perform both wind velocity measurement and self-motion detection using the same sensor. The wind sensor's ability to detect both environmental wind and sensor-induced motion allows the system to compensate for motion errors without adding dedicated motion sensors, thereby reducing overall device complexity while maintaining measurement accuracy.

AI summary
Techniques are disclosed for systems and methods to provide wind sensor motion compensation for wind sensors mounted to moving platforms. A wind sensor motion compensation system may include a wind sensor, a wind sensor accelerometer, one or more additional sensors, actuators, controllers, user interfaces, and/or other modules mounted to or in proximity to a vehicle. The wind sensor motion compensation system may be implemented with one or more logic devices adapted to receive sensor signals and determine a sensor-motion compensated wind velocity. The logic devices may be adapted to receive a wind sensor acceleration and a relative wind velocity from a wind sensor, determine a wind sensor velocity from the wind sensor acceleration, and determine a sensor-motion compensated relative wind velocity from the wind sensor velocity and the relative wind velocity.
