Solution Overview

Problem

Conventional internet terminals display private information, such as email content, on separate devices like telereceivers, leading to security issues as others can view sensitive information intended for the user.

Innovation Solution

A network apparatus comprising a main device linked to the Internet and a portable remote controller device that securely displays information by allowing the user to access and view private data on the remote controller device only, using infrared communication and unique identification codes to ensure privacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If private information is displayed on a separate display device like a telereceiver, then the user can view information remotely, but anyone around the display device can also see the information causing security leakage

Engineering Contradiction:

Improveremote viewing capabilityVSAvoidinformation security leakage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the display function from the main terminal and relocates it to a portable remote controller device. This separation allows the user to view private information on a portable device that can be carried away from others, eliminating the security issue of public display while maintaining remote viewing capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transitions from a fixed display location (telereceiver) to a portable display device that operates in a different spatial dimension. The portable remote controller can be moved to private locations, changing the spatial relationship between the user, the display, and potential eavesdroppers.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If a portable remote controller device is used to display information, then security is improved by allowing private viewing, but the device complexity increases due to additional components needed

Engineering Contradiction:

Improveinformation securityVSAvoidremote controller structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The portable remote controller device is designed to perform multiple functions: it serves as both a remote control for the main terminal and a display device for private information viewing. This multi-functionality reduces the need for separate dedicated devices while maintaining security benefits.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The portable remote controller acts as an intermediary device between the main terminal and the user's eyes. It receives information from the main terminal via infrared communication and displays it locally, mediating the information flow to ensure privacy while simplifying the overall system architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the main device stores access destinations for multiple remote controllers, then multiple users can access services simultaneously, but the system complexity increases with identification code management

Engineering Contradiction:

Improvemulti-user supportVSAvoididentification code storage and matching

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each portable remote controller contains its own identification code and uses it to automatically identify itself to the main terminal. The main terminal stores the correspondence between identification codes and access destinations, allowing automatic routing without manual intervention. This self-identifying mechanism simplifies multi-user management.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements a feedback mechanism where the remote controller sends its identification code to the main terminal, which then responds with the appropriate access destination. This automated feedback loop enables multiple users to access services simultaneously through their respective portable devices without manual configuration.

Inventive Principle:

Principle #23Feedback

AI summary

A remote controller device 2 sends its own ID code when specifying an access destination to a main device 1. Upon receipt of an access command from the remote controller device 2, the main device 1 appends the ID code of the remote controller device 2 to information obtained by accessing the access destination and outputs the same. The remote controller device 2 takes in the output only when it is appended with its own ID code and displays the same on a display unit 25. Thus, the user can confirm the information the main device 1 has obtained from the network 7 on the display unit 25 of the remote controller device 2. Consequently, the risk that the information is seen by anyone around can be reduced, thereby making it possible to improve the security on the private information.
