Engineering Contradiction Analysis
1Ease of operation
If hardware mechanisms are used to enable physical rotation in virtual reality, then the system provides tangible physical movement, but the range of rotational movement is restricted by hardware limitations
Solution Approach 1:
The patent applies parameter changes by implementing a nonlinear angle conversion function that transforms the relationship between virtual rotation angles and physical carrier rotation angles. This function dynamically adjusts the mapping parameters to expand the effective virtual rotation range beyond the physical hardware limits, allowing the system to provide unrestricted virtual rotational freedom while operating within hardware constraints.
2Adaptability or versatility
If the virtual angle range is expanded beyond carrier angle range, then virtual freedom of rotation is enhanced, but the mismatch between virtual and physical movements increases
Solution Approach 1:
The patent introduces an intermediary angle conversion function that acts as a mediator between the virtual angle range and the carrier angle range. This nonlinear conversion function smoothly maps virtual rotations to physical carrier rotations, ensuring that the alignment between virtual and physical movements is maintained even when the virtual angle range exceeds the physical carrier range. The conversion function serves as a bridge that resolves the mismatch while preserving both virtual freedom and movement reliability.

AI summary
A virtual reality control systems includes a base, a dynamic carrier that is disposed on the base and is configured to move along at least one rotational axis, and a control device that is connected to the dynamic carrier and is configured to determine a virtual rotation angle corresponding to a virtual operation, convert the virtual rotation angle into a carrier rotation angle, and control the rotational movement of the dynamic carrier based on the carrier rotation angle. The angle conversion function maps a virtual angle range to a carrier angle range in a nonlinear manner, such that the virtual rotation angle is within the virtual angle range and the carrier rotation angle is within the carrier angle range.
