Solution Overview

Problem

Traditional regional lock-state control systems, such as lockdown systems, fail to accurately determine the location of individuals within a predefined area after a lockdown event, leading to inefficiencies in managing lock states and potential safety risks.

Innovation Solution

A regional lock-state control system utilizing mobile devices and lock assemblies that communicate via wireless signals to transmit and receive lock-state directives, allowing for the determination of lock states and user locations through advertisements and status messages, enabling centralized control and tracking during events like lockdowns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a centralized lockdown system locks all doors automatically, then security control is improved, but the ability to track individual locations deteriorates

Engineering Contradiction:
Improvesecurity controlVSAvoidlocation information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system implements feedback by having mobile devices continuously scan for lock assembly advertisements and report status messages back to the central controller. This feedback loop provides real-time location information of individuals while maintaining centralized lock control, resolving the contradiction between security control and location tracking capability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Mobile devices serve as intermediaries between individuals and the centralized lock control system. They receive lockdown directives from the controller, transmit commands to lock assemblies, and report location data back to the controller, enabling both centralized control and individual location tracking simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If mobile devices continuously scan for lock advertisements, then location tracking precision is improved, but energy consumption increases

Engineering Contradiction:
Improvelocation tracking precisionVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

Instead of continuous scanning, the system uses periodic scanning where mobile devices scan for lock advertisements at defined intervals. This periodic action maintains location tracking precision while significantly reducing energy consumption compared to continuous scanning operations.

Inventive Principle:
Principle #19Periodic action

3Speed

If lock assemblies transmit advertisements frequently, then real-time status monitoring is improved, but network bandwidth consumption increases

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

Solution Approach 1:

Lock assemblies transmit advertisement messages at periodic intervals rather than continuously. This periodic transmission provides sufficient real-time status monitoring information while minimizing network bandwidth consumption and reducing overall system energy usage.

Inventive Principle:
Principle #19Periodic action
