Solution Overview

Problem

Existing emergency call systems face usability limitations and potential malfunctions due to separate units and speakers not being frequently used, making it difficult to determine if they are operational, which can lead to disputes during accidents.

Innovation Solution

An apparatus and method that unify a speaker, emergency call unit, and black box functionality, where the emergency call unit receives and outputs electric warning sounds, stores data for evidence, and includes a communication unit to transmit vehicle information to a call center upon airbag deployment, with a speaker integrated into the emergency call unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the emergency call system uses separate additional units and speakers, then the system can provide emergency call functions, but the usability is limited and it is difficult to determine whether they are out of order in ordinary times

Engineering Contradiction:
Improvedeterminability of unit and speaker functionalityVSAvoidusability outside emergency call purposes
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The emergency call unit is designed to perform multiple functions: it serves as both an emergency call device and a multimedia player. The unit can play music and other audio content during normal operation, while also functioning as an emergency call system when needed. This multi-functionality increases usability during ordinary times while maintaining emergency call capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system incorporates automatic testing functionality that periodically checks whether the additional unit and speaker are out of order. By continuously monitoring the operational status of these components through feedback mechanisms, the system can determine functionality without requiring separate manual testing, thus improving reliability determination while maintaining ease of operation.

Inventive Principle:
Principle #23Feedback

2Device complexity

If the additional unit and speaker are not frequently used, then the system maintains simplicity, but disputes may arise regarding potential malfunctions when an accident occurs

Engineering Contradiction:
Improvesystem structure simplicityVSAvoidverification of component functionality
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system performs automatic preliminary testing of the additional unit and speaker during normal operation. By conducting functionality checks before emergency situations occur, the system verifies component status in advance, creating a record of operational functionality that can prevent disputes regarding malfunctions when accidents occur.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The emergency call unit automatically tests and monitors its own components (additional unit and speaker) without requiring external intervention. This self-diagnostic capability allows the system to verify component functionality independently, maintaining simplicity while ensuring reliability verification through automated self-checks.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the emergency call system components are unified, then operator convenience is increased, but the system must handle multiple functions simultaneously

Engineering Contradiction:
Improveoperator convenienceVSAvoidfunctional integration requirements
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The emergency call unit and multimedia player are merged into a single integrated device. This consolidation allows the operator to use one unified interface for both emergency calls and audio playback, improving convenience by eliminating the need to switch between separate devices while managing multiple functions through a single control unit.

Inventive Principle:
Principle #5Merging (Combining)
