Solution Overview

Problem

Existing video security systems face vulnerabilities due to reliance on internet connectivity, difficulty in routing cables for multiple camera installations, and high energy consumption, particularly in scenarios where internet access is interrupted during security events, leading to unreliable operations and potential data loss.

Innovation Solution

An intelligent door lock system with a position sensing device, engine, and energy source notification system that provides real-time battery status updates to a server, allowing users to monitor and manage energy sources effectively, ensuring continuous operation and reducing vulnerabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If video security systems rely on internet connectivity for operation, then remote monitoring and data transmission capabilities are improved, but system reliability deteriorates when internet access is interrupted

Engineering Contradiction:
Improveremote monitoring capabilityVSAvoidsystem operation reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary actions by continuously monitoring battery status and proactively notifying users before battery depletion occurs. The server receives battery status information from the door lock system and sends notifications to user terminals in advance, allowing users to replace batteries before they are completely depleted, thus preventing system failure during operation.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If multiple cameras are installed with cabling connections, then video capture capability is improved, but installation complexity increases due to cable routing difficulties

Engineering Contradiction:
Improvevideo capture capabilityVSAvoidinstallation ease
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent extracts the power supply and communication functions from traditional cabled camera systems. The wireless camera system eliminates the need for complex cable routing by using wireless communication protocols for data transmission and battery-powered supplies for energy, thereby simplifying installation while maintaining video capture capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If video security systems operate continuously with high power consumption, then monitoring coverage is improved, but energy consumption increases

Engineering Contradiction:
Improvemonitoring coverageVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic action by scheduling battery status reporting at intervals rather than continuously. The door lock system reports battery status to the server at predetermined intervals, and the server sends notifications only when battery levels fall below threshold values, thereby reducing energy consumption while maintaining adequate monitoring coverage.

Inventive Principle:
Principle #19Periodic action
