1Measurement precision
If multiple specific sensors are used for different types of building products, then detection precision for each product type is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a universal sensor platform that can detect multiple types of building products (windows, doors, ventilation systems, rolling shutters) using a single device. The sensor incorporates an accelerometer, gyroscope, and magnetometer that can identify different product types through movement pattern recognition, eliminating the need for multiple specialized sensors while maintaining detection precision across all product categories.
Solution Approach 2:
The sensor changes its detection parameters and processing algorithms based on the identified building product type. Through learning programs that analyze movement characteristics, the sensor adapts its detection thresholds, sensitivity levels, and processing methods to optimize measurement precision for each specific product category, thereby maintaining high detection accuracy with a single multi-functional device.

3Device complexity
If a general-purpose sensor is used for all building products, then cost and complexity are reduced, but measurement precision for specific products may deteriorate
Solution Approach 1:
The sensor performs preliminary learning and characterization of the building product type through analysis of movement patterns, acceleration profiles, and operational characteristics during installation and initial operation. This preliminary action enables the sensor to pre-adapt its detection parameters and algorithms for the specific product category, ensuring high measurement precision from the outset without requiring multiple specialized sensors.
Solution Approach 2:
The sensor incorporates feedback mechanisms that continuously monitor detection results and refine its understanding of the specific building product type. Through iterative learning from operational data, the sensor optimizes its detection algorithms and parameters for each product category, thereby maintaining high measurement precision with a single general-purpose device that adapts to specific applications.
