Solution Overview

Problem

Existing communication systems require authentication even when the desired service is not available, leading to unnecessary user interaction and inconvenience.

Innovation Solution

A communication system that establishes a wireless connection without initial authentication, allowing the display of available functions on a terminal device, and only executes specific authentication when a desired function is selected for execution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If authentication is executed before displaying available functions, then security is improved, but user convenience deteriorates due to unnecessary authentication steps

Engineering Contradiction:

ImprovesecurityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the authentication process into two distinct phases: initial connection establishment (without authentication) and function execution (with authentication). This allows the system to display available functions first, then authenticate only when necessary, resolving the contradiction between security and user convenience by applying different security levels to different operational stages.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs the function display action before authentication, allowing users to see what functions are available before being prompted to authenticate. This preliminary display of information prevents unnecessary authentication attempts when desired functions are not available, improving user convenience while maintaining security for actual function execution.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If authentication is required for all connections, then security is improved, but communication efficiency deteriorates due to additional authentication overhead

Engineering Contradiction:

ImprovesecurityVSAvoidcommunication efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent divides communication into two segments: initial connection establishment (fast, no authentication) and function execution (authenticated). This segmentation eliminates authentication overhead for simple connection tasks while maintaining security for actual data exchange, thereby improving communication efficiency without compromising security.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies authentication partially - only when functions are actually executed - rather than excessively applying it to all communication stages. This partial application of authentication reduces unnecessary overhead while maintaining security where needed, resolving the contradiction between security and communication efficiency.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If PIN code authentication is executed before service availability check, then security is improved, but user interaction complexity increases

Engineering Contradiction:

ImprovesecurityVSAvoiduser interaction complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent performs the service availability check (displaying functions) before requiring PIN code authentication. This preliminary action allows users to understand what services are available before committing to the authentication process, reducing unnecessary interactions and simplifying the user experience while maintaining security for actual service execution.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent inverts the traditional authentication sequence by displaying available functions first, then authenticating later during function execution rather than before. This inversion reduces user interaction complexity by preventing unnecessary authentication attempts while maintaining security through conditional authentication based on actual service usage.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A function executing device may send screen display information to a terminal device via a first wireless interface without executing, via the first wireless interface, communication using specific authentication information, wherein the screen display information is for causing the terminal device to display a function screen. In a case where a first execution instruction for causing the function executing device to execute a first function is inputted to the terminal device after a function screen has been displayed in the terminal device, the function executing device may execute the communication using the specific authentication information with the terminal device via the first wireless interface and execute communication of first function execution information for executing the first function via the first wireless interface with the terminal device.
