Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle terminals require user intervention for resetting the calling number, leading to potential service disruptions and reduced customer convenience when services are canceled or expired.

Innovation Solution

A vehicle terminal system that automatically resets the calling number through communication with a communication management server in response to an error code, allowing the vehicle terminal to receive a new calling number without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a new calling number is assigned to the vehicle terminal after service cancellation or expiration, then the vehicle terminal can be reactivated for service, but user intervention is required to press the activation button which reduces customer convenience and may lead to service disruptions

Engineering Contradiction:

Improveservice reactivation reliabilityVSAvoidcustomer convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The vehicle terminal automatically detects when service has been canceled or expired by receiving an error code from the service server, and autonomously initiates the calling number reset process by communicating with the communication management server. This self-service mechanism eliminates the need for user intervention while ensuring reliable service reactivation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements a feedback loop where the vehicle terminal monitors service status by receiving error codes from the service server. When a service cancellation or expiration error is detected, the terminal automatically triggers the reset procedure. This feedback-driven approach ensures that the terminal only initiates reset when actually needed, maintaining both reliability and convenience.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If the vehicle terminal requires user intervention to activate service by pressing a button, then the activation process can be controlled by the user, but this manual process may be forgotten or neglected leading to service disruptions

Engineering Contradiction:

Improveuser controlVSAvoidservice continuity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The vehicle terminal autonomously monitors its own service status through error code detection and automatically executes the calling number reset procedure when service cancellation or expiration is detected. This self-service capability ensures service continuity without relying on user memory or attention, while still allowing users to initiate services through normal channels.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary monitoring of service status continuously, detecting cancellation or expiration conditions before they result in service disruption. By detecting the error state and automatically initiating reset procedures in advance, the system prevents service interruptions rather than reacting to them after users forget to act.

Inventive Principle:

Principle #10Preliminary action

3Ease of manufacture

If the vehicle terminal uses a preset calling number for communication, then initial service activation is straightforward, but the terminal cannot receive services after service cancellation or expiration without manual reconfiguration

Engineering Contradiction:

Improveinitial setup simplicityVSAvoidservice reactivation capability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The vehicle terminal dynamically adapts its calling number based on service status changes. The terminal maintains the preset calling number during normal operation for simple initial setup, but automatically detects service cancellation or expiration through error codes and dynamically resets the calling number through communication with the management server, enabling seamless service reactivation without manual reconfiguration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the calling number parameter automatically when service status changes. The vehicle terminal monitors service conditions, and upon detecting cancellation or expiration via error codes, it autonomously requests and applies a new calling number from the communication management server. This parameter change mechanism maintains ease of initial setup while providing adaptability for service reactivation.

AI summary

Provided are a vehicle terminal, a method and system for resetting the vehicle terminal, and a vehicle including the vehicle terminal for performing vehicle terminal resetting without user intervention. The vehicle terminal includes a modem connected to a preset communication network, and a processor configured to send a request for resetting a calling number to a communication management server that performs activation of the communication network such that the vehicle terminal is able to use the communication network in response to receiving a preset type of error code from a service server after requesting a service from the service server, receive a reset calling number provided from the communication management server, and change a current calling number to the reset calling number.
