Solution Overview

Problem

Existing wireless communication systems face challenges in securely and efficiently managing connections between wireless communication terminals using different communication protocols, leading to potential unintended connections and increased power consumption.

Innovation Solution

A wireless communication terminal equipped with both a first communication module for one-to-many connections and a second communication module for one-to-one connections, generates a network identifier based on terminal-specifying information, establishes a logical link, and starts a network on a higher layer, allowing secure and efficient communication while preventing unintended connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the wireless communication terminal uses the first communication protocol for one-to-many connections, then the ease of operation is improved, but the reliability of secure one-to-one connection is worsened

Engineering Contradiction:

Improveease of operationVSAvoidreliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The wireless communication terminal is divided into two separate communication modules: a first communication module for one-to-many connections and a second communication module for one-to-one connections. This segmentation allows each module to handle specific connection types with dedicated protocols, ensuring both ease of operation for group communications and reliability for secure point-to-point communications

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A network identifier generation unit acts as an intermediary between the first and second communication modules. It generates unique network identifiers based on terminal-specific information, which are then used by the second communication module to establish secure logical links. This intermediary ensures that secure one-to-one connections are properly established without compromising the ease of one-to-many communications

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the second communication module is started continuously for secure one-to-one connections, then the reliability is improved, but the power consumption is worsened

Engineering Contradiction:

ImprovereliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The second communication module is not continuously active but is periodically started only when secure one-to-one connection is required. The control unit manages the timing of starting the second communication module based on connection requirements, reducing unnecessary power consumption while maintaining reliability when needed

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The operational state of the second communication module is dynamically adjusted based on connection requirements. The control unit determines when to start and stop the second communication module, making the system adaptive to changing communication needs and optimizing power consumption accordingly

Inventive Principle:

Principle #15Dynamics

3Productivity

If the network is started immediately upon power supply, then the productivity is improved, but the power consumption is worsened

Engineering Contradiction:

ImproveproductivityVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The first communication module is started immediately upon power supply to enable one-to-many communications and network registration. The second communication module is started only when secure one-to-one connection is required, based on predetermined conditions. This preliminary action ensures productivity is maintained while avoiding unnecessary power consumption

Inventive Principle:

Principle #10Preliminary action

AI summary

A wireless communication terminal includes a first communication module performing wireless communication with an external terminal by using a first communication protocol; a second communication module performing wireless communication with the external terminal by using a second communication protocol; and a generation unit, wherein when the first communication module receives a connection request and terminal-specifying information specifying the external terminal, the generation unit generates a network identifier used for identifying a network using the second communication protocol based on the terminal-specifying information, the generation unit causes the second communication module to establish a logical link of communication with the external terminal by using the network identifier, and the generation unit subsequently causes the second communication module to start the network based on the network identifier such that the network is in a communicable state for the external terminal on a higher layer than a layer of the logical link.
