Automated Smart Doorbell Zone Detection and Notification Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current doorbell security systems are limited in providing a seamless user experience for monitoring visitors, often resulting in either excessive or inadequate notifications due to sensor sensitivity issues, and may require a push button that can malfunction or become unnecessary with advanced video and notification capabilities.
Innovation Solution
The Automated Smart Doorbell device employs sensors, including cameras and microphones, for detecting activities in defined zones, using facial recognition and voice recognition technologies to discriminate between human presence and other living beings, and adjusts sensitivity to trigger actions such as ringing a doorbell chime or sending notifications only when appropriate, thereby enhancing user experience and integration with smart devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the doorbell security system sensors are made highly sensitive to detect motion, then detection capability is improved, but excessive unwanted motion triggers and mobile user notifications are created
Solution Approach 1:
The patent divides the monitoring area into multiple zones with different sensitivity levels and detection rules. Motion sensors can be configured to monitor specific zones (e.g., front porch, driveway, backyard) with tailored sensitivity settings, allowing high sensitivity in critical areas while maintaining lower sensitivity in others to avoid excessive notifications.
Solution Approach 2:
The system allows dynamic adjustment of sensor sensitivity parameters through a remote interface. Users can modify detection thresholds, motion sensitivity, and notification triggers based on time of day, day of week, or specific events, optimizing the balance between detection accuracy and notification frequency.
2Device complexity
If the push button is removed to simplify the system, then device complexity is reduced, but reliability of doorbell function is worsened
Solution Approach 1:
The patent introduces a wireless communication module as an intermediary between the motion detection system and the doorbell chime. When motion is detected in specific zones, the system can remotely trigger the doorbell chime through wireless signals, eliminating the need for a physical push button while maintaining the doorbell function through an alternative reliable mechanism.
Solution Approach 2:
The mechanical push button system is replaced with an electronic wireless triggering system. The motion sensors and control circuitry detect presence and send wireless signals to activate the doorbell chime, substituting mechanical contact with electronic communication while preserving the essential doorbell alert function.
3Reliability
If the doorbell security system is made highly sensitive to ensure detection, then detection reliability is improved, but unnecessary notifications for non-human activity are increased
Solution Approach 1:
The patent segments the detection and notification processes into multiple stages. Motion detection is separated from human identification, with different algorithms and sensors used for each function. This allows the system to detect all motion reliably while filtering out non-human activity before generating notifications.
Solution Approach 2:
The system incorporates feedback loops where notification history and detection patterns are analyzed to refine future detection and notification behavior. The system learns from false positives and adjusts its sensitivity and notification thresholds to improve accuracy over time while maintaining reliable detection.
