Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional tracking technologies (video cameras, proximity sensors) are used, then tracking capability is provided, but coverage gaps and insufficient accuracy occur
Solution Approach 1:
The patent divides the tracking system into multiple radar modules operating at different frequencies (Ku-band, K-band, Ka-band), each covering specific spatial regions. This segmentation allows each radar to focus on particular areas while collectively providing comprehensive coverage without gaps, resolving the contradiction between tracking accuracy and coverage continuity.
Solution Approach 2:
The patent introduces a frequency dimension to the tracking system by employing radars across multiple frequency bands (Ku: 12-18 GHz, K: 18-27 GHz, Ka: 26.5-40 GHz). This dimensional addition enables the system to overcome the limitations of single-frequency radars, achieving both high accuracy and continuous coverage through complementary characteristics of different frequency bands.
2Reliability
If tracking technology is implemented, then object monitoring is enabled, but privacy concerns arise
Solution Approach 1:
The patent extracts and processes only the essential tracking information (position, movement, presence) from the radar data, discarding unnecessary detailed information that could compromise privacy. By taking out only the minimal required data for safety monitoring while avoiding comprehensive surveillance, the system maintains tracking reliability without excessive privacy intrusion.
Solution Approach 2:
The patent introduces an intermediary processing layer between the radar system and the final tracking output. This intermediary layer filters, anonymizes, and processes raw radar data to produce privacy-preserving tracking information, acting as a buffer that protects privacy while maintaining tracking functionality.
3Measurement precision
If multiple radar bands are used, then tracking accuracy and coverage are improved, but system complexity increases
Solution Approach 1:
The patent designs a universal radar system architecture where multiple radar modules (Ku-band, K-band, Ka-band) share common processing infrastructure, control systems, and data fusion algorithms. This multi-functionality approach allows the system to achieve enhanced tracking accuracy through multiple frequency bands while minimizing the increase in overall system complexity through standardized components and unified processing pipelines.

AI summary
This disclosure enables various technologies for tracking various objects (e.g., mammals, animals, humans, pets) within various defined areas (e.g., rooms, apartments, residences, vehicles, tents) to determine whether those objects satisfy or do not satisfy various criteria, signatures, or thresholds, which may relate to health, safety, or security of those objects within those defined areas. These technologies may be enabled via various radars (e.g., time-of-flight radars, Doppler radars) positioned within those defined areas to track those objects therein. For example, some of such radars may operate in a Ku-band inclusively between about 12 GHz and about 18 GHz, a K-band inclusively between about 18 GHz and about 27 GHz, or a Ka-band inclusively between about 26.5 GHz and about 40 GHz, each of which has been unexpectedly found to be technologically beneficial for tracking those objects within those defined areas.
