Alert Transmission Device Using Dynamic Physical Characteristic Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security systems fail to detect unauthorized entry through alternative routes like windows, leading to potential safety risks and false alarms when friends or relatives are mistaken for trespassers.
Innovation Solution
A method and device that obtain physical characteristic data of a target object, such as pressure, contact area, and temperature, to determine if it is a human, and transmit an alert message to a terminal if the data does not match pre-stored user data, adjusting the data range based on user motion to avoid false alarms, and sending control commands to security devices like locks or video recording systems upon confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical characteristic data matching is used to identify unauthorized individuals, then detection accuracy is improved, but false alarms occur when friends or relatives are mistaken for trespassers
Solution Approach 1:
The system adjusts the physical characteristic data range dynamically based on user motion data. When motion is detected, the system expands the acceptable data range to accommodate variations in posture and movement, thereby reducing false alarms while maintaining detection accuracy for stationary unauthorized individuals.
Solution Approach 2:
The matching condition is made dynamic rather than static. The system continuously updates the physical characteristic data range based on real-time motion detection, allowing the identification criteria to adapt to the user's current state and reduce misidentification of friends or relatives.
2Reliability
If the physical characteristic data range is adjusted based on user motion, then false alarms are reduced, but system complexity increases
Solution Approach 1:
The target device is designed to perform multiple functions: it detects physical characteristic data, monitors user motion, dynamically adjusts identification parameters, and triggers security responses. This multi-functionality is achieved within a single integrated system, managing complexity through unified design rather than separate components.
Solution Approach 2:
The system automatically adjusts the physical characteristic data range based on its own motion detection capabilities, without requiring external intervention or complex configuration. The device serves itself by using its motion sensor data to dynamically optimize its identification parameters.
3Measurement precision
If multiple physical characteristic parameters are monitored, then identification accuracy is improved, but processing load increases
Solution Approach 1:
The system extracts and processes only the essential physical characteristic parameters (pressure, contact area, temperature) needed for identification. By selecting only the most relevant parameters and processing them through efficient matching algorithms, the system maintains high identification accuracy while minimizing unnecessary computational overhead.
