Solution Overview

Problem

Existing security systems for homes and commercial properties face challenges with cabling difficulties, vulnerability to internet disruptions, and energy consumption issues, particularly in door lock systems that require continuous video streaming and recording.

Innovation Solution

An intelligent door lock system coupled with a camera that communicates via Bluetooth, allowing it to record only when the door is opened and closed, reducing unnecessary recording and energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If continuous video recording is implemented in door lock systems, then security monitoring capability is improved, but energy consumption increases

Engineering Contradiction:
Improvesecurity monitoring capabilityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The camera is configured to record video only during specific time periods when door locking or unlocking events occur, rather than operating continuously. This periodic recording approach maintains security monitoring capability for critical events while significantly reducing energy consumption during idle periods when no events are occurring.

Inventive Principle:
Principle #19Periodic action

2Productivity

If multiple cameras are connected via cabling to a security box, then video capture capability is improved, but installation complexity increases

Engineering Contradiction:
Improvevideo capture capabilityVSAvoidinstallation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The camera is extracted from the traditional security box system and integrated directly into the door lock assembly. This allows the camera to be positioned optimally for capturing entry events without requiring complex cabling runs to a separate security box, thereby reducing installation complexity while maintaining video capture capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Speed

If video is transmitted continuously over network, then real-time monitoring is improved, but network bandwidth consumption increases

Engineering Contradiction:
Improvereal-time monitoringVSAvoidnetwork bandwidth consumption
Core Design Contradiction:
SpeedVSLoss of energy

Solution Approach 1:

Video transmission occurs periodically only when door locking or unlocking events are detected, rather than continuous streaming. This approach provides real-time monitoring capability for security events while minimizing network bandwidth consumption during periods when no events are occurring.

Inventive Principle:
Principle #19Periodic action
