Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional mmWave imaging systems use bulky mechanical motion controllers or rigid bodies to move the mmWave device in a predetermined trajectory, then the system can achieve higher measurement precision for object detection, but the device complexity and portability are significantly reduced
Solution Approach 1:
The patent replaces the mechanical motion controller and rigid body movement system with an electronic signal processing approach. Instead of physically moving the mmWave device along a predetermined trajectory using motors and mechanical controllers, the system uses electronic beamforming and signal processing techniques to achieve synthetic aperture radar functionality, thereby eliminating bulky mechanical components while maintaining detection precision
Solution Approach 2:
The patent integrates multiple functions into a single compact device. The mmWave sensor device combines object detection, classification, and tracking capabilities in one unit, eliminating the need for separate mechanical motion controllers and multiple specialized components. This multi-functional integration reduces overall system complexity and improves portability while maintaining measurement precision
2Measurement precision
If multiple sensors are activated simultaneously for security detection, then the measurement precision and reliability of object detection are improved, but the power consumption increases significantly
Solution Approach 1:
The patent activates the mmWave sensor device first as a preliminary detection stage before activating other sensors. The mmWave sensor performs initial object detection and classification, and only if an object of interest is detected does the system then activate video cameras or infrared sensors for confirmation. This preliminary action approach ensures high detection accuracy while minimizing power consumption by keeping additional sensors inactive during normal operation
Solution Approach 2:
The system uses periodic activation of additional sensors based on detection needs rather than continuous operation. The video camera or infrared sensor is activated only in periodic intervals when the mmWave sensor detects potential threats requiring further investigation, thereby maintaining detection precision while significantly reducing overall power consumption compared to continuous multi-sensor operation
3Reliability
If traditional concealed weapons detection systems use bulky equipment with constant power sources, then the reliability of detection is improved, but the ease of operation and deployability are reduced
Solution Approach 1:
The patent changes the power supply parameter from constant power sources to rechargeable battery power. This allows the device to be portable and easily deployed in various locations without requiring access to electrical outlets. The system maintains reliable detection performance while enabling mobile operation through battery power and periodic sensor activation that optimizes energy usage
Solution Approach 2:
The patent combines multiple sensor types (mmWave sensor, video camera, infrared sensor) and processing functions into a single integrated device. This merging of components maintains the reliability of detection through multi-sensor confirmation while improving ease of operation by creating a self-contained, portable unit that can be easily deployed and operated without complex external equipment

Function Achieved in This Case
This approach enhances detection accuracy by minimizing false positives and reduces power consumption, enabling a covert, mobile, and efficient system for real-time security alerts.
Implementation Method 1
Traditional mmWave imaging systems operate under the Synthetic Aperture Radar (SAR) principle. They use bulky, mechanical motion controllers or rigid bodies that move the mmWave device in a predetermined trajectory forming an aperture. As it moves along the aperture, the device transmits a wireless signal and measures the reflections bounced off of the nearby objects.
Implementation Method 2
activating, in response to a content of a generated predicted label, at least one video camera or infrared sensor device, associated with the indicated region of interest, to provide an output from the at least one video camera or infrared sensor device

AI summary
A method of detecting security incidents and generating alerts receives an input from an mmWave sensor device, such input associated with potential security incidents, such input indicating a region of interest where an object of interest is present; processes the received input using an artificial intelligence (AI) engine and generates predicted labels describing the object of interest and the potential security incidents; activates in response to a content of a generated predicted label, a video camera, processes the output from the video camera using the AI engine to generate predicted labels describing the object of interest and the potential security incidents; and provides alerts to at least one of a plurality of output devices, where a value of a predicted label indicates a detection of a particular object of interest or a particular security incident.
