Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multi-dimensional data are captured by the tracking system, then data reliability and measurement precision are improved, but data processing time and system complexity increase
Solution Approach 1:
The patent segments the complex multi-dimensional data processing into distinct phases: data acquisition from multiple sensors, preliminary filtering, feature extraction, and analysis. This segmentation allows each phase to be optimized independently, maintaining measurement precision while reducing overall processing time through parallel processing capabilities.
Solution Approach 2:
The patent transitions from processing raw multi-dimensional sensor data to extracting key features and patterns that represent the essential information in a reduced dimensional space. This dimensionality reduction maintains the reliability needed for accurate measurement while making the data computationally tractable for real-time processing.
2Adaptability or versatility
If more monitoring components are installed on equipment, then monitoring coverage and detection capability are improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent employs a multi-functional monitoring platform that can accommodate various sensor types (accelerometers, gyroscopes, temperature sensors, humidity sensors) through a unified data acquisition and processing architecture. This universal platform provides comprehensive monitoring coverage across multiple parameters while avoiding the complexity of separate dedicated systems for each sensor type.
Solution Approach 2:
The patent combines multiple monitoring functions and sensor types into an integrated system that shares common processing resources, data storage, and analysis algorithms. This merging approach achieves comprehensive monitoring coverage while reducing overall system complexity compared to separate dedicated monitoring systems.
3Productivity
If conventional processors are used for data analysis, then system simplicity is maintained, but data processing speed and analysis capability are insufficient
Solution Approach 1:
The patent replaces conventional mechanical processors with specialized processing units optimized for sensor data analysis, including FPGA or GPU-based systems that can perform parallel processing of multi-dimensional data streams. This substitution dramatically increases data processing speed and analysis capability while managing system complexity through modular architecture.
Solution Approach 2:
The patent implements a dynamic processing architecture that adapts the level of processing intensity and computational resources allocated based on the current operational context, data characteristics, and priority requirements. This dynamic approach enables high-speed processing when needed while maintaining system simplicity during normal operations.
Data Source
AI summary
A multi-object tracking method includes generating multi-dimensional physical characterization data associated with a plurality of objects; simplifying the multi-dimensional physical characterization data to reduce at least one dimension thereof, thereby resulting in a simplified data set; and tracking by comparing a current simplified data set and a stored data set in a database. If the current simplified data set conforms to the stored data set in the database, a proper operation is correspondingly performed; otherwise the current simplified data set is defined as a new event and stored in the database.
