Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional virtual driving simulation systems use actual vehicle platforms with motion platforms and rails, then driving realism is improved, but adaptability to future mobility with various seat shapes and interior spaces deteriorates
Solution Approach 1:
The patent creates a digital twin of the driving environment that copies and simulates vehicle dynamics, visual scenes, and auditory effects in virtual space. Instead of relying on physical motion platforms, the system uses computational models to replicate driving sensations, allowing adaptation to various seat configurations without requiring physical reconfiguration of the simulation platform.
Solution Approach 2:
The patent replaces the mechanical motion platform system with a software-based simulation system that generates virtual driving experiences through computer-generated visuals, auditory feedback, and haptic interfaces. This substitution eliminates the constraint of fixed vehicle platforms and enables flexibility in accommodating different seat shapes and interior spaces.
2Stability of the object's composition
If virtual driving simulation uses fixed vehicle cabin platforms, then simulation stability is improved, but versatility for future mobility scenarios deteriorates
Solution Approach 1:
The patent creates a universal simulation system that can accommodate multiple vehicle types and mobility scenarios through software configuration rather than physical reconfiguration. The digital twin technology allows the same simulation platform to stabilize and test various vehicle designs, seat arrangements, and driving scenarios, providing both stability through consistent simulation methodology and versatility through adaptable virtual environments.
3Reliability
If conventional systems rely on physical motion platforms, then feedback realism is improved, but system complexity and cost deteriorates
Solution Approach 1:
The patent replaces complex mechanical motion platforms with software-based visual and auditory simulation systems combined with simpler haptic feedback devices. The system generates realistic driving feedback through computer-generated imagery, spatial audio, and controlled haptic sensations, achieving comparable realism with reduced mechanical complexity and lower system cost.
