Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication systems during emergencies often fail to maintain group communication integrity, leading to disruptions when emergency signals are transmitted, as they typically create new groups, isolating original group communications.

Innovation Solution

A base station device and terminal device system that receives and transmits emergency signals while maintaining existing group structures, allowing communication within and between groups by using a receiver and transmitter to broadcast emergency signals to all terminal devices, including those in different groups if they are within a predetermined distance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a new group is created for emergency communication, then emergency signal transmission is achieved, but original group communication is disrupted

Engineering Contradiction:

Improveemergency signal transmissionVSAvoidoriginal group communication

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent segments the communication function into two independent paths: normal communication remains within original groups while emergency communication creates a separate transmission path through the base station to all terminal devices, preventing disruption to original group structures

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base station acts as an intermediary that receives emergency signals from terminal devices and redistributes them to all terminal devices across all groups, enabling emergency communication without requiring changes to the original group compositions

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If emergency signals are transmitted to all terminal devices regardless of group, then emergency response coverage is improved, but communication privacy between groups is compromised

Engineering Contradiction:

Improveemergency response coverageVSAvoidgroup communication privacy

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent implements dynamic communication routing where the base station intelligently determines which terminal devices should receive emergency signals based on their group memberships and current communication states, allowing flexible coverage while preserving appropriate privacy boundaries

Inventive Principle:

Principle #15Dynamics

AI summary

In a base station device, a receiver receives a normal signal from one terminal device included in one of a plurality of groups each including a plurality of terminal devices. The transmitter transmits the normal signal received by the receiver to the rest of the terminal devices included in the group. When the receiver has received an emergency signal from one terminal device included in one group, the transmitter transmits the emergency signal that has been received by the receiver to the rest of the terminal devices included in the group and terminal devices other than those in the group.
