Solution Overview

Problem

Existing security inspection network systems are vulnerable to failures as they rely on a central server for operation, leading to system breakdowns if the server malfunctions or if network links are disconnected, even if security inspection devices and workstations remain operational.

Innovation Solution

Implementing a security inspection terminal that can search for and connect with other terminals within the network, allowing direct communication between security inspection devices and workstations without relying on a server, and utilizing correspondence relationship information to establish connections and synchronize data when the server is unavailable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a central server is used to manage security inspection data, then system operation is simplified and data management is centralized, but the system becomes vulnerable to server failures and network disconnections

Engineering Contradiction:
Improvecentralized data managementVSAvoidsystem continuity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent divides the centralized server-based system into distributed peer-to-peer segments. Each terminal device maintains local data storage and can independently communicate with other terminals, breaking the single point of failure into multiple independent operational units that can function autonomously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces correspondence relationship information as an intermediary mechanism that enables indirect communication between terminals. When direct communication is unavailable, terminals use stored correspondence data to establish alternative communication paths, maintaining system operation without requiring constant server mediation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If direct peer-to-peer communication is implemented between terminals, then fault tolerance improves and system reliability increases, but device complexity increases due to need for searching and connection management

Engineering Contradiction:
Improvefault toleranceVSAvoidconnection management
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent performs preliminary actions by pre-storing correspondence relationship information in each terminal before actual communication needs arise. This advance preparation eliminates the need for complex real-time discovery and connection establishment, reducing operational complexity while maintaining reliable peer-to-peer communication paths.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the system continuously monitors server availability and switches to peer-to-peer mode, then system reliability improves during server failures, but loss of time occurs during detection and switching processes

Engineering Contradiction:
Improvesystem availabilityVSAvoidfailure detection and switching time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary configuration of correspondence relationship information during system initialization or idle periods, so that when server failure occurs, terminals already have the necessary connection data ready. This eliminates time delays associated with real-time discovery and switching, enabling immediate transition to peer-to-peer mode.

Inventive Principle:
Principle #10Preliminary action
