Three-axis rotation system and method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for rotating a human body to diagnose and treat vestibular and other systems are limited as they cannot rotate independently around three perpendicular axes, restricting the degree and independence of rotation, which hampers therapeutic effectiveness for conditions like brain injuries and neurodegenerative disorders.
Innovation Solution
A three-axis rotation system comprising a yaw frame within a roll frame, with a pitch frame contained within the yaw frame, driven by respective motors, allowing independent rotation around orthogonal pitch, roll, and yaw axes, and a unique drive system using belts and shafts to transmit mechanical power outside the rotational space, minimizing electromagnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-axis or two-axis rotation system is used, then the device complexity is reduced, but the adaptability and therapeutic effectiveness are limited
Solution Approach 1:
The patent implements a nested frame structure where the pitch frame is contained within the yaw frame, which is contained within the roll frame. Each frame can rotate independently about its own axis while being carried by the outer frames. This nesting arrangement enables three-axis rotation capability without requiring three completely separate mechanical systems, thus achieving high adaptability while controlling device complexity.
Solution Approach 2:
The rotation system is segmented into three independent rotational modules (pitch, yaw, roll frames), each capable of independent rotation about its own axis. This segmentation allows the system to achieve complex three-dimensional rotation capabilities by combining simpler individual rotation modules, improving therapeutic effectiveness while managing overall system complexity.
2Object-affected harmful factors
If motors are located inside the rotational space, then the drive system is simplified, but electromagnetic interference increases
Solution Approach 1:
The patent extracts the motors from the internal rotational space and relocates them to the external support frame. The drive system uses belts and shafts that extend through the rotational frames to transmit power from the externally located motors. This extraction eliminates electromagnetic interference with the sensors and measurement systems within the rotational space, while the external mounting simplifies motor cooling and maintenance.
