Wireless Speaker Tone Alert for Weak Network Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless audio/video (A/V) recording and communication devices, such as doorbells, lack an efficient mechanism to alert users of visitor presence across a wide area network, leading to delayed or missed notifications, especially when the user's local network connection is weak or unreliable.
Innovation Solution
A wireless speaker device configured to receive a tone signal from a wide area network via a local area network, which emits a tone when a visitor is detected by an A/V recording and communication device, ensuring timely alerts even in areas with weak network connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wireless A/V recording and communication device is used to detect visitors, then visitor detection capability is improved, but reliable alert notification to users is compromised when network connection is weak
Solution Approach 1:
The patent introduces a wireless speaker device as an intermediary component between the A/V recording device and the user's smartphone. This speaker device receives tone signals from the A/V device via wireless communication and converts them into audible alerts, providing a reliable notification mechanism that does not depend on the user's smartphone being connected to the network, thus resolving the contradiction between detection capability and notification reliability.
Solution Approach 2:
The system is divided into separate functional components: the A/V recording device for detection, the wireless speaker device for alert generation, and the user's smartphone for remote access. This segmentation allows the alert notification function to operate independently through the speaker device, ensuring reliability even when network connections are weak or the user is away from home.
2Productivity
If a tone signal is transmitted via LAN and WAN networks, then remote communication capability is improved, but notification delay increases in areas with weak network connections
Solution Approach 1:
The wireless speaker device acts as a local intermediary that receives tone signals directly from the A/V recording device through wireless communication within the home network. This eliminates the need for tone signals to travel through WAN networks to the user's smartphone, significantly reducing notification delay and removing dependency on external network connections.
3Area of stationary object
If a wireless repeater is added to extend network coverage, then network coverage area is improved, but device complexity increases
Solution Approach 1:
The wireless speaker device serves as a local intermediary that processes alert signals within the home network without requiring extensive network coverage extensions. By placing the speaker device strategically within the existing network coverage area, the system achieves reliable local alert generation without adding wireless repeaters or expanding network infrastructure.

AI summary
A wireless speaker device configured for use with a wireless A/V recording and communication device, such as a doorbell. The wireless speaker device, which includes a speaker, may connect to the user's local area network (LAN), such as a Wi-Fi network. The LAN is connected to a wide area network (WAN), such as the Internet and/or a public switched telephone network (PSTN). When the wireless A/V recording and communication device detects a visitor, it sends a signal, via the LAN, to at least one device in the WAN, such as a server and/or a service. In response, the at least one device in the WAN sends a signal, via the LAN, to the wireless speaker device. The signal to the wireless speaker device includes a command for the wireless speaker device to emit a tone through its speaker. The wireless speaker device then emits a tone through its speaker to alert the user that a visitor is at the wireless A/V recording and communication device. The wireless speaker device may further include a wireless repeater configured to receive a wireless signal from the one or more LAN devices and rebroadcast the wireless signal. The wireless speaker device may further include a wireless communication module configured to transmit data wirelessly to and/or receive data wirelessly from another wireless device, independently of the LAN, via a direct connection to the another wireless device.
