Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motion simulators, particularly spherical ones, often cause disorientation and nausea due to the positioning of occupants across quadrants, leading to a disconnect between the simulated experience and real-world sensations, and are often expensive and complex in design.
Innovation Solution
A virtual motion-acceleration spherical simulator with occupants positioned within individual quadrants of a sphere, utilizing a unique drive system with reduction pulleys and geared motors, allowing whole-body acceleration in the same direction, combined with advanced audiovisual and feedback systems for immersive simulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If occupants are positioned across quadrants (upper body in central line, lower body below line), then the simulator can accommodate multiple occupants, but this causes disorientation, nausea and discomfort due to opposite acceleration directions
Solution Approach 1:
The patent positions occupants in specific quadrants of the spherical simulator where their bodies are aligned with the rotation axis rather than across quadrants. This asymmetric positioning ensures that acceleration forces act uniformly along the same direction for all occupants, preventing the disorientation and nausea that would result from opposite acceleration directions.
Solution Approach 2:
The patent creates different positioning configurations for different occupants within the sphere, with each occupant positioned in a quadrant optimized for their orientation. This local optimization ensures that each person experiences acceleration in the correct direction relative to their body orientation, eliminating discomfort while maintaining multi-occupant capacity.
2Power
If a large and powerful engine is used to drive the spherical simulator, then high motion acceleration and realism are achieved, but the cost and complexity of the system increases significantly
Solution Approach 1:
The patent utilizes the spherical geometry of the simulator to achieve efficient motion distribution. By positioning occupants within the sphere and utilizing rotational movement around the sphere's axis, the system generates realistic acceleration forces through the curved path, maximizing the effectiveness of the drive mechanism while minimizing the power required compared to linear or non-spherical configurations.
Solution Approach 2:
The spherical design creates equipotential conditions for force distribution, where the rotational motion generates consistent acceleration forces throughout the occupant positions. This geometric optimization allows the system to achieve high motion acceleration capability with a more modestly sized engine, as the spherical geometry efficiently converts rotational input into uniform acceleration across all occupant locations.
