Solution Overview

Problem

Existing intercommunication systems on vehicles broadcast audio data to all units before establishing a private communication channel, disturbing unaffected users.

Innovation Solution

A method and device that utilize voice recognition to identify the recipient of a message and transmit it directly to their seat, if on a different row, with sound reproduction devices emitting sounds only audible to the occupant, allowing for private communication between seats on different rows.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If audio data is broadcast to all intercommunication units before establishing a private channel, then the message can be delivered to the recipient, but users not affected by the message are disturbed

Engineering Contradiction:
Improvemessage deliveryVSAvoidnoise disturbance
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the message transmission from the general broadcast channel and directs it specifically to the recipient's intercommunication unit. The system identifies the recipient through voice recognition and routes the audio data exclusively to that unit, eliminating unnecessary exposure for other users.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements location-based message routing where the message is delivered to a specific local unit (the recipient's intercommunication unit) rather than broadcasting to all units. This localizes the message delivery to only where it is needed, preventing disturbance to other users.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If voice recognition is used to identify the recipient, then direct message transmission is enabled, but system complexity increases

Engineering Contradiction:
Improvemessage transmissionVSAvoidsystem structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system uses voice recognition technology to automatically identify the recipient and route the message without requiring manual intervention. The intercommunication units and control system autonomously perform the identification and routing tasks based on the voice command analysis.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual message routing operations with automated voice recognition and digital signal processing. Instead of physical or manual switching mechanisms, the system uses electronic voice analysis and automated routing algorithms to direct messages to the correct recipient.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The invention relates to a method for controlling an intercommunication system onboard a vehicle (100) comprising a plurality of seats (111, 112), each equipped with a sound reproduction device, said seats (111, 112) being distributed in rows in the vehicle (100), and at least a first sound acquisition device (131), the method being characterised in that it comprises steps of: detecting the reception, by a first sound acquisition device (131), of a voice message from a first vehicle occupant; controlling an analysis of the message, carried out by a voice recognition module, and identifying a second occupant who is designated in the message and is the intended recipient of the message; determining a first seat (111) and a second seat (112); if the first seat (111) and the second seat (112) are in different rows, then controlling a broadcast of the message by the sound reproduction device (122) of the second seat (112).
