Solution Overview

Problem

Existing voice dialing systems for vehicles require manual selection and connection of mobile devices, leading to inconvenience and increased accident risk due to time consumption while driving.

Innovation Solution

An automatic dialing system that connects to multiple mobile devices, utilizing a telephone directory database, an instruction receiving unit, a telephone directory search unit, a mobile device connection unit, and a dialing control unit to automatically dial a phone number based on a driver's voice instruction, without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual selection and connection of mobile devices is required for voice dialing, then the system can dial from connected devices, but the driver experiences inconvenience and increased accident risk due to time consumption

Engineering Contradiction:

Improveease of dialing operationVSAvoidtime for device connection

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically selecting and connecting to the appropriate mobile device before the dialing operation is initiated. The automatic dialing system pre-establishes the connection by searching for the mobile device associated with the contact and connecting to it automatically, eliminating the need for manual device selection and connection during the dialing process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system serves itself by automatically performing the device selection and connection tasks without requiring driver intervention. The automatic dialing system independently identifies which mobile device contains the desired contact information and establishes the connection autonomously, freeing the driver from these manual operations.

Inventive Principle:

Principle #25Self-service

2Reliability

If manual device connection is required, then the system can maintain stable connection, but the driver's attention is diverted increasing accident risk

Engineering Contradiction:

Improveconnection stabilityVSAvoidaccident risk from driver distraction

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs the connection management tasks autonomously without requiring driver participation. The automatic dialing system independently selects and connects to the appropriate mobile device, eliminating driver distraction while maintaining reliable connections through automated device selection and connection establishment.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If the system supports multiple mobile devices, then the driver can access phone numbers from any device, but the complexity of device management increases

Engineering Contradiction:

Improveability to dial from multiple devicesVSAvoidcomplexity of device connection management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system automatically manages multiple mobile devices by independently identifying which device contains the desired contact information and connecting to that device automatically. This self-service approach allows the system to support multiple devices without increasing operational complexity for the driver, as the automatic dialing system handles all device management tasks autonomously.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The automatic dialing system acts as an intermediary between the driver's dialing request and the multiple mobile devices. It receives the dialing instruction, automatically searches through multiple devices to find the contact, and establishes the connection without requiring the driver to manually manage device selections, thereby simplifying the interface between the user and multiple devices.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An automatic dialing system includes a telephone directory database configured to store first terminal information which includes a first telephone directory and first identification information and second terminal information which includes a second telephone directory and second identification information. An instruction receiving unit is configured to receive a dialing instruction. A telephone directory search unit is configured to search for a telephone directory. A mobile device connection unit is configured to connect the second mobile device corresponding to the automatic dialing system, when the found telephone directory corresponds with the second telephone directory. A dialing control unit is configured to dial a phone number corresponding to the received instruction through the second mobile device, when the found telephone directory corresponds with the second telephone directory.
