Solution Overview

Problem

Existing methods for information transmission between separated spaces, such as a vehicle interior and exterior, require devices or tools, compromising the separation state when windows are opened.

Innovation Solution

A conversation assisting apparatus that uses an isolation object, like a vehicle window, to transmit acoustic signals by emitting and picking up sounds, emphasizing the received sound to maintain separation without additional devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a device or tool is placed in the vehicle to transmit information, then information transmission is enabled, but the separation state between vehicle interior and exterior cannot be maintained when the window is opened

Engineering Contradiction:

Improveinformation transmissionVSAvoidseparation state

Core Design Contradiction:

Loss of informationVSStability of the object's composition

Solution Approach 1:

The vehicle window glass serves as an intermediary medium to transmit acoustic signals from the interior to the exterior. The sound transmission unit converts sound to vibrations that propagate through the glass, and the sound reception unit converts these vibrations back to sound, enabling information transmission while maintaining the physical separation and closed-window state.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical communication devices (telephones, tablets, pens) with an acoustic vibration system. Sound waves are converted to mechanical vibrations of the window glass, which then transmit the information acoustically to the other side, eliminating the need for electronic devices or writing tools.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If the window is opened to transmit information by speech, then information transmission is enabled, but the isolation between the two spaces is lost

Engineering Contradiction:

Improveinformation transmissionVSAvoidloss of isolation

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The window glass acts as a mediator that allows acoustic communication without physical opening. Sound vibrations are transmitted through the glass medium, enabling easy verbal communication while the window remains closed, thus maintaining the isolation and safety of the vehicle interior.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces the mechanical action of opening the window with an acoustic vibration mechanism. Instead of physically opening the window to speak, the sound transmission unit converts speech to vibrations that travel through the closed window, achieving the same communication goal without compromising isolation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of information

If traditional communication devices are used, then information can be transmitted, but additional devices and tools are required in the vehicle

Engineering Contradiction:

Improveinformation transmissionVSAvoidnumber of devices

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The vehicle window glass is given a dual function: it serves both as the traditional isolation barrier and as a sound transmission medium. This eliminates the need for separate communication devices, as the existing structural component (window) performs both isolation and communication functions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The vehicle's existing window structure serves the additional function of sound transmission without requiring external devices. The sound transmission and reception units utilize the window's inherent physical properties to transmit vibrations, allowing the vehicle structure itself to provide the communication capability.

Inventive Principle:

Principle #25Self-service

AI summary

A conversation assisting method of the present invention is performed in a first space in order to transmit an acoustic signal between the first space and a second space, separated by an isolation object, by using the isolation object. In the conversation assisting method of the present invention, a sound to be transmitted to the second space is emitted from the first space side to the isolation object at a predetermined intensity. Further, in the conversation assisting method of the present invention, a sound transmitted through the isolation object is picked up, and from the picked-up sound, a sound except for the emitted sound is emphasized and output.
