Engineering Contradiction Analysis
1Manufacturing precision
If conventional driving simulation systems use standard motion platforms, then the system structure is simple and easy to manufacture, but the system cannot accurately replicate intense lateral G forces and abrupt directional changes, leading to motion sickness and reduced realism
Solution Approach 1:
The motion platform is divided into multiple independent rotational planes (first plane with first rotation plate, second plane with second rotation plate, fourth plane with fourth rotation plate), each capable of rotating about its own axis. This segmentation allows each plane to independently contribute to lateral G force generation, enabling accurate replication of complex driving dynamics while maintaining modular construction that balances manufacturing feasibility with simulation precision
Solution Approach 2:
The invention introduces multiple superimposed rotational planes arranged in three-dimensional space with non-coaxial axes. The first rotation plate rotates about a first axis, the second rotation plate rotates about a second axis, and the fourth rotation plate rotates about a fourth axis, creating multi-dimensional motion capabilities. This dimensional expansion enables the system to generate intense lateral G forces and abrupt directional changes that single-plane platforms cannot achieve, thereby improving simulation accuracy without requiring excessive structural complexity
2Reliability
If the simulation system uses superimposed non-coaxial rotation plates, then lateral G forces are accurately replicated, but the device complexity and structural configuration increase significantly
Solution Approach 1:
Multiple rotation plates (first, second, and fourth planes) are superimposed and integrated into a single motion platform structure. The rotation plates are arranged such that their axes are non-coaxial, allowing them to work together synergistically to generate lateral G forces. This merging approach consolidates multiple rotational functions into one unified structure, improving simulation realism while avoiding the need for separate independent platforms that would increase overall system complexity
Solution Approach 2:
The system employs dynamically controllable rotation plates that can rotate about fixed axes during operation. The first rotation plate, second rotation plate, and fourth rotation plate are each driven by independent drive mechanisms, allowing real-time adjustment of rotational speed and direction. This dynamic capability enables the platform to accurately replicate varying lateral G forces and abrupt directional changes encountered in real driving scenarios, enhancing simulation realism without requiring a static overly-complex structure
3Reliability
If motion platforms replicate abrupt directional changes, then driving realism is improved, but motion sickness is induced due to conflict between expected and actual sensory input
Solution Approach 1:
The system incorporates sensors that detect the actual motion state of the platform and provide feedback to the control system. This feedback mechanism allows the control system to monitor and adjust the rotational movements of the first, second, and fourth rotation plates in real-time, ensuring that the generated lateral G forces and directional changes match the expected driving scenario. By providing sensory feedback that aligns with visual input, the system improves driving realism while minimizing motion sickness caused by sensory conflict
Solution Approach 2:
The system dynamically adjusts the rotational parameters (speed, direction, amplitude) of the first, second, and fourth rotation plates to match the driving scenario being simulated. By precisely controlling these parameters, the platform can replicate gradual directional changes for normal driving conditions while avoiding excessive or conflicting motions that trigger motion sickness. This parameter control allows the system to maintain high driving realism while managing the harmful effects of motion sickness

AI summary
A driving experience simulation device includes at least five superimposed planes, the planes being in sequence from the bottom upwards: a first plane in turn including a first rotation plate; a second plane in turn including a second rotation plate; a third plane including a track-like structure for the sliding of an overlying sliding base; a fourth plane in turn including the sliding base, a fourth rotation plate integrally joined beneath the sliding base, a support supporting the fourth rotation plate and slidable in the structure; and a fifth plane including at least one cockpit the simulation device being characterised in that the track-like structure of the third plane is constrained to the underlying second rotation plate by way of a pin, the latter constraining the front smaller side of the rectangular profile of the track-like structure with the edge of the underlying rotation plate of the second plane.
