Solution Overview

Problem

Conventional vehicles require opening windows or doors to communicate with outside individuals, leading to increased fuel consumption and inconvenience, especially in extreme weather conditions, and pose safety risks for hearing-impaired individuals who cannot hear warning signals.

Innovation Solution

A system comprising a proximity sensor unit, wind blowing unit, light emitting unit, memory unit, and voice transmission units that allow communication between inside and outside a vehicle without opening windows, using wind and light signals for alerting pedestrians and amplifying voice signals to ensure safety for hearing-impaired individuals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If windows or doors are opened to communicate with outside individuals, then communication is enabled, but fuel consumption increases and convenience decreases in extreme weather conditions

Engineering Contradiction:

Improvecommunication convenienceVSAvoidfuel consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent introduces a wind blowing unit that generates artificial wind to transmit voice signals from inside to outside the vehicle without opening windows. This intermediary device (wind blowing unit) mediates the communication process, allowing voice transmission while maintaining closed windows and preventing direct air exchange that would increase fuel consumption.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If windows or doors are opened to communicate with outside individuals, then communication is enabled, but convenience decreases due to frequent opening required

Engineering Contradiction:

Improvecommunication convenienceVSAvoidtime lost from frequent opening

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The wind blowing unit serves as an intermediary that enables continuous communication without requiring window opening. Once activated, it allows two-way voice transmission while windows remain closed, eliminating the repeated opening/closing actions that waste time and reduce convenience.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If conventional warning devices use sound signals, then warning is provided to pedestrians, but hearing-impaired individuals cannot perceive the signal

Engineering Contradiction:

Improvewarning effectivenessVSAvoidsignal perception for hearing-impaired

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent changes the parameter of the warning signal from acoustic (sound) to mechanical (wind). The wind blowing unit generates strong air flow that can be physically felt by pedestrians, including hearing-impaired individuals. This parameter change from sound-based to touch-based signaling expands the adaptability of the warning system to accommodate different sensory capabilities.

Inventive Principle:

Principle #35Parameter changes

4Device complexity

If voice signals are transmitted without amplification, then simplicity is maintained, but transmission accuracy decreases

Engineering Contradiction:

Improvesystem simplicityVSAvoidvoice signal transmission accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent replaces the need for electronic amplification with a mechanical approach. The wind blowing unit uses strong air flow to physically carry voice signals from the microphone to the speaker, substituting mechanical energy for electronic amplification. This maintains relative simplicity while improving transmission accuracy through the physical force of the wind.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
