Nested Two-Axis Rotator for Precise Cryogenic Sample Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current two-axis rotators in solid-state physics are limited in their ability to adjust desired orientations of material samples in high magnetic fields and cryogenic temperatures, leading to residual incorrect orientations and the inability to conduct complete angle-dependent property examinations.
Innovation Solution
A two-axis rotator design that allows independent rotation about two orthogonal axes, utilizing a base member, first and second rotors with drives, and worm gear drives for precise angular positioning, enabling simultaneous control of both axes within a compact structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If known two-axis rotators are used in solid state physics, then rotation about two axes is enabled, but simultaneous driving of both axes is not possible or only limited angular range is achieved
Solution Approach 1:
The patent implements a nested rotor structure where a first rotor is rotatably supported on a base member about a first rotation axis, and a second rotor is rotatably supported on the first rotor about a second rotation axis. This nesting enables both rotation axes to be driven simultaneously and independently, achieving complete angular coverage without requiring complex external mechanisms.
2Ease of operation
If limited angular range for sample rotation is provided, then device structure is simplified, but desired orientations of material samples cannot be adjusted
Solution Approach 1:
The patent employs two independently driven rotors with worm gear drives that can rotate through full 360 degrees on each axis. The first rotor provides rotation about the first axis while the second rotor provides rotation about the second axis, enabling the sample to be positioned at any desired orientation with high precision through coordinated control of both axes.
3Extent of automation
If no simultaneous driving of both axes is enabled, then device complexity is reduced, but completely automated measurement of angle-dependent properties is not possible
Solution Approach 1:
The patent divides the drive system into two independent worm gear drive mechanisms, each controlling one rotation axis. The first worm gear drive rotates the first rotor about the first axis, and the second worm gear drive rotates the second rotor about the second axis. This segmentation allows both axes to be driven simultaneously and independently, enabling fully automated measurement of angle-dependent sample properties.
