Solution Overview

Problem

Current audio/video (A/V) recording and communication devices, such as doorbells, lack the capability to effectively identify and respond to potential dangers, like known criminals or weapons, in real-time, especially when power conservation is a concern in battery-powered devices.

Innovation Solution

Implementing network communication between A/V recording and communication devices and a second camera through a backend server, where the second camera, with different performance characteristics, analyzes image data to determine potential dangers, triggering the first camera to record high-resolution images for law enforcement use, while conserving battery power by maintaining the first camera in a low-power state until needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the first camera operates continuously at high resolution to detect potential dangers, then the detection capability and response time are improved, but the battery power consumption increases

Engineering Contradiction:
Improvedetection capabilityVSAvoidbattery power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary actions by having the second camera continuously capture low-resolution images and transmit them to the backend server for pre-analysis. This preliminary detection of potential dangers allows the system to prepare for high-resolution capture only when necessary, resolving the contradiction between continuous detection capability and battery conservation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The detection system is segmented into two independent cameras with different resolutions and power consumption characteristics. The second camera handles continuous low-power monitoring, while the first camera performs high-resolution capture only when triggered by the backend server's analysis, thereby reducing overall power consumption while maintaining detection reliability.

Inventive Principle:
Principle #1Segmentation

2Use of energy by moving object

If the first camera remains in low-power state to conserve battery, then energy efficiency is improved, but the response time for capturing potential dangers increases

Engineering Contradiction:
Improvebattery power consumptionVSAvoidresponse time
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The backend server acts as an intermediary between the second camera and the first camera. It receives continuous low-resolution image data from the second camera, analyzes it for potential dangers, and only then triggers the first camera to activate. This intermediary approach allows rapid detection of threats while keeping the high-power camera in a low-power state most of the time.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary analysis of potential dangers using the second camera and backend server before activating the first camera. This preliminary action reduces the response time by ensuring that the first camera is activated only when a threat is detected, rather than requiring it to be continuously active.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If network communication with a second camera and backend server is implemented, then the detection accuracy for known criminals is improved, but the device complexity increases

Engineering Contradiction:
Improvedetection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Instead of using a single complex high-resolution camera with advanced processing capabilities, the system uses a simpler second camera that continuously captures low-resolution images. These images are transmitted to a backend server that performs the complex analysis and comparison against databases of known criminals. This copying approach distributes complexity across multiple components rather than concentrating it in one device.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The backend server serves as an intermediary that handles the complex tasks of image analysis, pattern recognition, and comparison against criminal databases. This externalizes the complexity from the doorbell device itself, allowing the device to remain relatively simple while achieving high detection accuracy through networked processing power.

Inventive Principle:
Principle #24Intermediary (Mediator)
