Solution Overview

Problem

There is a need to enhance the coordination and convenience of networks that include multiple IoT devices, particularly in scenarios where devices use different protocols and require secure authentication for coordinated operations.

Innovation Solution

An information processing apparatus and method that utilize a controller to acquire authentication data from a mobile device, generate operation commands for other devices, and transmit these commands, enabling coordinated operations among IoT devices through electronic key-based authentication, with features like location-based triggering and secure data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If devices in a network use different protocols for communication, then device compatibility and network coverage are improved, but coordination difficulty and system complexity increase

Engineering Contradiction:
Improvedevice compatibilityVSAvoidcoordination difficulty
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a server as an intermediary component that mediates communication between IoT devices using different protocols. The server receives authentication results from a first device, processes the data, and generates appropriate operation commands for a second device. This intermediary architecture enables protocol translation and coordination without requiring direct compatibility between endpoint devices, thus resolving the contradiction between device compatibility and coordination difficulty.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If electronic key-based authentication is implemented for secure device coordination, then security and reliability are improved, but authentication process complexity and processing time increase

Engineering Contradiction:
Improveauthentication securityVSAvoidauthentication process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex authentication processing logic from the individual IoT devices and centralizes it in the server. The first device only needs to perform local authentication with the mobile device and transmit the result to the server. The server then handles the complex task of verifying the authentication result, retrieving stored data, and generating operation commands. This extraction reduces the authentication process complexity for endpoint devices while maintaining security through centralized verification.

Inventive Principle:
Principle #2Taking out (Extraction)

3Manufacturing precision

If centralized server processing is used for generating operation commands, then coordination accuracy and control precision are improved, but communication time and system latency increase

Engineering Contradiction:
Improvecoordination accuracyVSAvoidcommunication time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent implements preliminary action by having the server store operation command templates and device coordination rules in advance. When authentication is successful, the server retrieves pre-prepared data and generates operation commands more quickly, rather than creating everything from scratch in real-time. This preliminary preparation reduces the processing time for coordination operations while maintaining accuracy through structured, pre-validated command templates.

Inventive Principle:
Principle #10Preliminary action
