Solution Overview

Problem

Existing battery electric vehicles lack the ability to simulate multiple vehicle characteristics, such as sound and acceleration, without requiring user input for selection, which can be cumbersome and reduce user satisfaction.

Innovation Solution

A battery electric vehicle system that reproduces characteristics of multiple virtual vehicles using a processor to read information from a registration medium, allowing automatic selection and simulation of desired vehicle sounds and driving sensations without user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the system provides multiple virtual mobility options for selection, then the adaptability and user preference satisfaction are improved, but the ease of operation deteriorates due to the additional selection step required

Engineering Contradiction:
Improvevirtual mobility selectionVSAvoidselection operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs preliminary action by automatically selecting and determining a virtual mobility based on information from a registration medium before the user needs to use it. The processor reads information from the registration medium and autonomously selects the corresponding virtual mobility, eliminating the need for manual user selection and thereby improving ease of operation while maintaining adaptability.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the system requires user input for selecting virtual mobility, then the adaptability is maintained, but the productivity and user satisfaction deteriorate due to the additional user effort required

Engineering Contradiction:
Improvevirtual mobility simulationVSAvoidvehicle operation efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system applies self-service by enabling the processor to automatically determine and select the virtual mobility using information from the registration medium without requiring user intervention. The system serves itself by autonomously completing the selection process, which improves productivity and user satisfaction while maintaining the adaptability to provide multiple virtual mobility options.

Inventive Principle:
Principle #25Self-service
