Solution Overview

Problem

Existing driving simulators, particularly those for Gran Turismo, fail to accurately replicate the pitching, rolling, and yawing movements of vehicles, especially during intense maneuvers, limiting the realism of the simulation experience.

Innovation Solution

A support system for driving simulators is designed with decoupled mechanisms for pitching/rolling and yawing movements, utilizing a rest base, lower and upper plates, and movement means to independently simulate these movements, including linear actuators and guides to ensure precise replication of vehicle motions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If actuators are used to simulate pitching, rolling and yawing movements in a unified manner, then the structure is simplified, but the accuracy and realism of movement replication deteriorates

Engineering Contradiction:
ImprovestructureVSAvoidmovement replication accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent divides the movement simulation system into separate functional modules: a first platform for pitching and rolling movements, and a second platform for yawing movements. This segmentation allows each platform to be optimized independently for its specific movement type, improving overall accuracy while maintaining manageable structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary coupling mechanism between the first and second platforms that enables coordinated movement while maintaining independent control. This intermediary structure allows the two platforms to work together as a unified system without compromising the accuracy of individual movement simulations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If a unified platform is used for all movements, then the device complexity is reduced, but the ability to accurately simulate intense maneuvers deteriorates

Engineering Contradiction:
Improveplatform structureVSAvoidsimulation realism during intense maneuvers
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent segments the simulation platform into two independent platforms: a first platform optimized for pitching and rolling movements, and a second platform optimized for yawing movements. This segmentation enables each platform to be specifically designed and calibrated for its designated movement type, ensuring high reliability during intense maneuvers that require precise movement replication.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If decoupled mechanisms are used for pitching/rolling and yawing movements, then the accuracy of movement simulation is improved, but the device complexity increases

Engineering Contradiction:
Improvemovement simulation accuracyVSAvoidmechanism structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements decoupled mechanisms by separating the simulation into two independent platforms, each with its own actuation system. The first platform uses actuators optimized for pitching and rolling, while the second platform uses actuators optimized for yawing. This segmentation improves movement simulation accuracy by allowing each mechanism to be independently optimized.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges the two decoupled platforms through a coupling mechanism that coordinates their movements. This merging allows the system to achieve the benefits of decoupled accuracy while presenting a unified interface to the user, effectively managing the complexity through integrated control.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of manufacture

If prior art simulation systems are used, then the basic simulation function is provided, but the realism of vehicle movement replication deteriorates significantly

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent applies segmentation by dividing the simulation system into specialized platforms for different movement types, enabling more realistic vehicle movement replication compared to prior art unified systems. This segmentation allows each platform to be optimized for specific movements, significantly improving realism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by giving each platform specific characteristics optimized for its designated movement type. The first platform has properties optimized for pitching and rolling, while the second platform has properties optimized for yawing, ensuring that each local component contributes to overall simulation realism.

Inventive Principle:
Principle #3Local quality
