Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional mechanical positioning system is used, then the structure is simple and easy to manufacture, but the freedom of motion and versatility are limited
Solution Approach 1:

A complex magnetic object with multiple magnetic domains interacts with spatially and temporally varying magnetic fields generated by an array of magnetic field generators, enabling six-degree-of-freedom positioning and orientation without mechanical constraints
Solution Approach 2:
The complex magnetic object serves multiple functions simultaneously: it is actuated by magnetic fields for positioning, carries sample materials, and can be oriented in any direction. The system can perform various operations including positioning, orienting, and manipulating samples in three-dimensional space, replacing multiple separate mechanical systems
2Adaptability or versatility
If a magnetic field system with multiple magnetic domains is used, then the freedom of motion increases, but the control complexity and difficulty of detection increase
Solution Approach 1:
The system incorporates feedback mechanisms where the positions and orientations of complex magnetic objects are continuously monitored and used to adjust the magnetic field generation. This enables precise control of multiple degrees of freedom by dynamically adjusting the magnetic field parameters based on real-time object states
3Adaptability or versatility

AI summary
A method is provided for positioning and orienting a platform such as a sample or workpiece relative to a frame of reference where the platform is a complex magnetic object that contains at least two magnetic domains with non-collinear magnetic moments and the method includes generating a spatially and temporally varying magnetic field so that each magnetic moment of the complex magnetic object interacts with the applied magnetic field. This can be used to performs an operation on a workpiece such as addition or removal of material. This can be used where the object includes a sample and, in each measurement configuration of the sample, radiation transmitted, reflected or scattered is measured from said sample material and analyzed to obtain information about the sample material.
