Engineering Contradiction Analysis
1Device complexity
If conventional motion simulation systems use simple rotational platforms to simulate turns, then the device complexity is reduced, but the measurement precision of lateral G accelerations deteriorates
Solution Approach 1:
The simulation system is divided into multiple independent rotational platforms (first platform for yaw, second platform for roll, third platform for pitch) that can rotate around different axes. Each platform handles specific rotational degrees of freedom, allowing complex lateral G acceleration vectors to be decomposed and reproduced through coordinated rotation of segmented components rather than requiring a single complex mechanism.
Solution Approach 2:
The system transitions from simulating turns in a single rotational plane to multi-dimensional motion by adding rotational platforms that operate on different axes (vertical axis for yaw, horizontal axes for roll and pitch). This dimensional expansion enables accurate reproduction of lateral G accelerations that occur in three-dimensional space during sharp turns, overcoming the limitations of simple two-dimensional rotational platforms.
2Measurement precision
If multiple rotational platforms are used to accurately reproduce lateral G accelerations, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
Each rotational platform is designed to perform multiple functions: the first platform provides yaw rotation and serves as the mounting base for the second platform, while also contributing to lateral G acceleration generation. The second platform provides roll rotation and mounting for the third platform, while also generating lateral G components. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing complexity despite the multi-platform architecture.
Solution Approach 2:
The rotational platforms are arranged in a nested configuration where the second platform is mounted on the first platform, and the third platform is mounted on the second platform. This nesting allows the platforms to share structural support and control systems, reducing overall device complexity. The nested arrangement also enables compact packaging of multiple rotational degrees of freedom while maintaining the precision needed for accurate lateral G acceleration reproduction.
3Productivity
If the simulation system uses sharp and sudden direction changes to reproduce realistic driving experiences, then the training effectiveness is improved, but kinetosis effects are induced in users
Solution Approach 1:
The control system continuously monitors the positions and orientations of all three rotational platforms and adjusts their motion in real-time to match the virtual driving conditions while minimizing disorienting effects. By providing feedback from sensors that detect actual platform orientations and user position, the system can fine-tune the simulation to maintain training effectiveness while reducing harmful kinetosis effects through compensatory adjustments.
Solution Approach 2:
The system dynamically adjusts motion parameters such as rotation speed, acceleration rates, and platform orientation angles to reproduce realistic driving scenarios. By carefully controlling these parameters—using slower, more gradual rotational movements when possible while still achieving realistic lateral G accelerations—the system maintains training effectiveness without inducing severe kinetosis. Parameter changes allow the system to adapt between different simulation scenarios, balancing realism with user comfort.

AI summary
A motion simulation system includes at least five superimposed planes, the planes sequentially being from the bottom upwards: a first plane in turn including a first rotational plate; a second plane in turn including a second rotational plate; a third plane including a track-like structure for the sliding of an overlying slidable base; a fourth plane in turn including the slidable base, a fourth rotational plate integrally joined beneath the slidable base; a fifth plane including at least one cockpit adapted to enable the access of the user of the motion simulation system, the system allowing the continuous reproduction of the forces associated with the lateral accelerations that are developed when negotiating curves and trajectories typical of Formula 1 racetracks and of motorcycle competition racetracks.
