Doorbell Wireless Communication System for Remote Visitor Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional doorbells do not effectively alert remotely located individuals when someone is trying to communicate, as the alerting sound may not be heard by individuals outside the immediate vicinity, leading to a need for devices and methods to remotely notify occupants of visitor presence.
Innovation Solution
A doorbell system that wirelessly communicates with a remotely located computing device, enabling visitors to alert users through a network connection mode, using sensors to detect visitor presence and send notifications via wireless networks, including the Internet and cellular networks, even when the user is not physically close.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional doorbell uses an alerting sound to notify occupants of visitor presence, then the notification function is achieved, but the notification range is limited to short distance only and remotely located individuals cannot be alerted
Solution Approach 1:
The patent introduces a remotely located computing device as an intermediary between the doorbell and the occupant. The doorbell sends visitor presence information to the computing device via wireless communication, which then relays the notification to the occupant's mobile device, enabling remote notification beyond the limited acoustic range of traditional doorbells
Solution Approach 2:
The patent replaces the mechanical acoustic notification system with an electronic wireless communication system. Instead of relying solely on acoustic waves that propagate limited distances, the system uses electromagnetic waves (wireless networks, Internet, cellular networks) to transmit visitor presence information over long distances to remotely located occupants
2Ease of operation
If a doorbell system adds wireless communication capability to enable remote notification, then the notification range is extended, but the device complexity increases
Solution Approach 1:
The patent makes the computing device perform multiple functions: it acts as a wireless communication bridge between the doorbell and the occupant's mobile device, stores visitor presence information, and relays notifications. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while enabling remote notification
3Ease of operation
If the doorbell continuously transmits data wirelessly to enable remote communication, then the remote notification function is achieved, but the energy consumption increases
Solution Approach 1:
The patent implements periodic transmission instead of continuous transmission. The doorbell transmits visitor presence information to the computing device only when a visitor is detected (periodic event-driven transmission), and the system maintains wireless connectivity through periodic updates rather than constant data flow, reducing overall energy consumption while maintaining remote notification capability
