Solution Overview

Problem

Existing vehicle control systems cannot dynamically change various specifications of a traveling vehicle, limiting user customization and experience.

Innovation Solution

A vehicle control device that acquires ID information from a terminal, specifies associated vehicle information, and controls the vehicle to change its specifications, including driving characteristics, based on the ID information, allowing for the reproduction of desired vehicle types and characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If vehicle specifications are changed through manufacturing modifications, then the driving characteristics and vehicle type can be altered, but the complexity and cost of manufacturing increase significantly

Engineering Contradiction:

Improvevehicle specification changeabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent changes vehicle specifications by modifying operational parameters (driving characteristics information) rather than physical structure. The control device reads ID information, retrieves corresponding driving characteristics data, and adjusts vehicle control parameters to simulate different vehicle types, avoiding complex manufacturing changes while achieving specification variability.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates virtual copies of different vehicle types by storing and reproducing driving characteristics information for multiple vehicle types. Instead of physically modifying the vehicle, the system copies the behavioral characteristics of target vehicle types and applies them through software control, enabling specification changes without manufacturing complexity.

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If multiple vehicle types are supported through physical modifications, then adaptability improves, but the cost and time for manufacturing and customization increase

Engineering Contradiction:

Improvevehicle type varietyVSAvoidcustomization time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by pre-storing driving characteristics information for multiple vehicle types in advance. When a user wants to change vehicle specifications, the system simply retrieves the pre-prepared data corresponding to the desired vehicle type and applies it immediately, eliminating the need for time-consuming physical modifications or customizations.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If display device specifications are adjusted for user preference, then user convenience improves, but the ability to change other vehicle specifications remains limited

Engineering Contradiction:

Improvedisplay customizationVSAvoidvehicle specification range

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent extends the customization capability from just display devices to comprehensive vehicle control. The same ID-based retrieval mechanism that previously only adjusted display specifications now controls multiple vehicle systems including acceleration, braking, and steering characteristics, making the system universal and enabling both display and driving parameter customization through a single interface.

Inventive Principle:

Principle #6Universality (Multi-functionality)
