Solution Overview

Problem

Conventional doorbells with integrated video cameras have a larger form factor, making installation difficult and reducing battery life due to the video camera's operation.

Innovation Solution

A smart doorbell without a video camera that communicates wirelessly with external IoT devices, allowing for flexible placement of cameras and extended battery life by transmitting activation signals to external video cameras and speakers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a video camera is integrated within the doorbell housing, then video monitoring function is provided, but the form factor increases making installation difficult

Engineering Contradiction:
Improvevideo monitoring functionVSAvoiddoorbell form factor
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The doorbell system is divided into separate functional components: the doorbell housing contains only the button and chime functions, while the video camera is a separate external device. This segmentation allows the doorbell to maintain a compact form factor while still providing video monitoring capability through wireless communication between the separated components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The video camera is extracted from the doorbell housing and placed as an external device. This extraction reduces the doorbell's form factor to a compact size suitable for easy installation, while the video monitoring function is preserved through the external camera that communicates wirelessly with the doorbell system.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If a video camera is operated within the doorbell, then video monitoring is enabled, but battery life is reduced due to increased power consumption

Engineering Contradiction:
Improvevideo monitoring functionVSAvoidbattery life
Core Design Contradiction:
Adaptability or versatilityVSDuration of action of moving object

Solution Approach 1:

The power-consuming video camera function is separated from the battery-powered doorbell unit. The external camera has its own power source, allowing the doorbell's battery to be used only for essential functions (button press and chime), thereby extending battery life while maintaining video monitoring capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The video camera is extracted as a separate externally powered device, removing its power consumption burden from the doorbell's battery. This allows the doorbell battery to last longer since it only needs to power the minimal doorbell functions, while the external camera handles video monitoring with its own power supply.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If multiple doorbell chimes are provided, then user customization options increase, but device complexity increases

Engineering Contradiction:
Improvedoorbell chime selectionVSAvoiddoorbell system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The doorbell system is designed to work with multiple types of external devices (wireless speakers, video cameras, display devices) through a universal wireless communication interface. This multi-functionality allows the doorbell to provide customized chime experiences through different external devices without increasing the complexity of the core doorbell unit, as the same wireless interface handles various device types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for a smart doorbell comprising a housing. In an embodiment, an activation of a user interface element of the smart doorbell is detected. In response to detecting the activation of the user interface element, a determination is made that a doorbell chime is to be activated based on one or more rules, a first signal to activate the doorbell chime is caused to be transmitted, and a wireless signal is transmitted to at least one video camera that is not included within the housing. The wireless signal causes the at least one video camera to activate and provide a video stream.
