Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current simulation technologies, such as virtual reality and flight training simulations, lack the ability to provide a highly immersive and realistic experience, particularly in terms of physical movement and sensory input, which limits their fidelity and engagement for users.
Innovation Solution
A motion control system that includes a suspension structure, marionette assembly, and navigation controller, allowing for controlled three-dimensional movement and sensory feedback through winch-rope assemblies, dampening mechanisms, and sensors, which simulate physical environments like flight and falling by manipulating the user's position and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual reality and flight training simulations are used, then users can experience simulated environments, but the physical movement and sensory input fidelity remains insufficient
Solution Approach 1:
The patent combines virtual reality visual simulation with physical motion simulation by integrating a motion control system that suspends and moves the user's entire body through three-dimensional space. This merging of visual and physical simulation domains creates a unified immersive experience where both sensory inputs are synchronized, resolving the contradiction between simulation fidelity and system complexity by making the complex system necessary for achieving high-fidelity results.
Solution Approach 2:
The motion control system is divided into separate functional modules: a suspension structure for supporting the user, a marionette assembly with winch-rope assemblies for controlling movement, and a navigation controller for coordinating actions. This segmentation allows each component to be optimized independently while working together to achieve high-fidelity simulation, addressing the complexity issue through modular design.
2Ease of operation
If physical movement and sensory feedback are added to simulations, then user immersion is enhanced, but the system complexity and infrastructure requirements increase
Solution Approach 1:
The motion control system serves multiple functions simultaneously: it suspends the user, provides three-dimensional movement control, enables rotational orientation, and coordinates with virtual reality visual displays. This multi-functionality achieves high user immersion through a single integrated system rather than requiring separate complex subsystems, resolving the contradiction between ease of operation and device complexity.
3Reliability
If controlled three-dimensional movement is implemented, then realistic physical sensations are provided, but the device complexity increases
Solution Approach 1:
The navigation controller acts as an intermediary that coordinates between the virtual reality system and the physical motion system. It receives input from the VR environment and translates it into appropriate physical movements through the marionette assembly, ensuring synchronization between visual and physical stimuli. This intermediary approach simplifies the overall control architecture while maintaining realistic physical sensations.
Solution Approach 2:
The system implements feedback mechanisms where the navigation controller continuously monitors the user's position and orientation in three-dimensional space and adjusts the motion control accordingly. This feedback loop ensures that physical sensations remain synchronized with the virtual environment, enhancing realism while managing system complexity through adaptive control.

AI summary
A simulated environment includes a motion control system. The motion control system may comprise a suspension structure, a housing slidably engaged to the suspension structure such that the suspension controller translates in a planar manner relative to the suspension structure. A rotary component may be rotatably attached to the housing. A plurality of winches may be attached to the rotary component, the plurality of winches having cables to allow longitudinal movement of the cables parallel to a force of gravity.
