Solution Overview

Problem

Existing wireless communication systems lack the ability to transmit messages to specific users within a predetermined area without prior registration or specific user designation.

Innovation Solution

A wireless communication system comprising wireless communication terminals and a repeater, where the terminals include an acquisition unit for user operations, a transmission unit for sending messages and direction information to the repeater, and a message reception unit. The repeater has a map information storage unit, a position specifying unit, and a control unit that determines a communication area based on map information, position information, and direction information, allowing messages to be transmitted to other terminals within the designated area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If message transmission requires prior user registration and specific user designation, then communication accuracy is improved, but communication efficiency and ease of operation deteriorate

Engineering Contradiction:
Improvecommunication accuracyVSAvoidease of message transmission
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The predetermined area is divided into multiple smaller areas, allowing the system to segment the communication target from a large space into manageable zones. This enables users to select specific areas rather than individual users, maintaining communication accuracy while simplifying the operation process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces an area-based intermediary mechanism between the user and the message recipient. Instead of directly designating specific users, the communication is routed through area selection, which acts as a mediator to achieve both accuracy and ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the predetermined area is divided into multiple areas, then message transmission precision is improved, but device complexity increases

Engineering Contradiction:
Improvemessage transmission precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The area division is implemented as a logical segmentation rather than physical complexity. The map information storage unit stores pre-defined area boundaries, and the control unit performs logical operations to determine which areas receive messages, avoiding unnecessary hardware complexity while achieving precise message transmission.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If area-based communication is implemented without prior registration, then ease of operation is improved, but reliability of message delivery deteriorates

Engineering Contradiction:
Improveease of message transmissionVSAvoidmessage delivery reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary actions by pre-dividing the predetermined area into multiple areas and storing this map information in advance. This preliminary structuring enables the system to reliably route messages to the correct areas without requiring real-time user registration or complex runtime decisions.

Inventive Principle:
Principle #10Preliminary action

AI summary

A wireless communication system, a repeater, and a wireless communication method capable of transmitting a message to another user in a specific area selected by a user are provided. The wireless communication system includes a plurality of wireless communication terminals and the repeater. The wireless communication terminal acquires an operation of a user, and transmits a message and direction information. The repeater determines a communication area based on the received information, and transmits a message to another wireless communication terminal worn by a user in the communication area.
