Solution Overview
Problem
Conventional doorbells often fail to accurately detect visitors, leading to false negatives or false positives, and may not alert remotely located individuals effectively, especially if they are unable to hear the alerting sound.
Innovation Solution
A doorbell system that includes a camera and motion detection capabilities, allowing it to take images and analyze them for visitor presence, with configurable detection zones on a remote computing device, enabling accurate visitor detection and alerting through wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional doorbells use simple alerting sounds, then the device complexity is low, but the reliability of alerting remotely located individuals is poor
Solution Approach 1:
The patent replaces the mechanical acoustic alerting system with an electronic communication system. The doorbell system captures images via camera, transmits them wirelessly to remote computing devices, and uses electronic notifications instead of relying solely on acoustic chimes. This substitution enables reliable remote alerting while maintaining reasonable device complexity through integration of standard electronic components.
Solution Approach 2:
The patent introduces a wireless communication intermediary (network infrastructure and remote computing devices) between the doorbell and the user. Instead of direct acoustic transmission, the system uses image capture and electronic communication as intermediaries to relay visitor information to remotely located individuals, ensuring reliable notification regardless of distance or hearing capability.
2Measurement precision
If doorbells use motion detection to detect visitors, then the productivity of visitor detection is improved, but the measurement precision leads to false positives and false negatives
Solution Approach 1:
The patent segments the visitor detection process into multiple independent components: motion detection serves as a trigger, followed by image capture and analysis as a separate verification step. This segmentation allows the system to use motion detection for initial sensitivity while employing image analysis for precise verification, thereby reducing false positives while maintaining high detection productivity.
Solution Approach 2:
The system implements feedback by analyzing captured images to verify motion detection events. When motion is detected, the system captures an image and analyzes it to confirm actual visitor presence before triggering an alert. This feedback loop corrects false positives from motion detection while maintaining responsive detection, improving overall reliability without sacrificing productivity.
3Measurement precision
If doorbells use camera-based visitor detection, then the measurement precision of visitor presence is improved, but the device complexity increases
Solution Approach 1:
The patent applies multi-functionality by using the camera for multiple purposes: visitor detection, image capture for transmission, and potential security monitoring. This universal use of the camera component justifies the added device complexity, as one component serves multiple functions that collectively improve measurement precision while the system remains integrated and manageable.
Solution Approach 2:
The system merges the camera, image processing, and wireless communication functions into an integrated doorbell system. By combining these functions rather than treating them as separate systems, the patent manages device complexity through integration while maintaining the measurement precision benefits of camera-based detection. The merged system operates as a unified unit with coordinated components.
Data Source
AI summary
Doorbells can be used to detect visitors. A picture taken by the doorbell can be sent to a computing device. A user of the computing device can select areas within the picture. The doorbell can then detect visitors within the selected areas. Subsequent pictures from the doorbell can be analyzed according to the selected areas.
