Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple motors are configured to provide multi-dimensional power, then the precision machine can operate in multiple dimensions, but the weight of the machine increases
Solution Approach 1:
The patent combines three single-dimensional motors into a single integrated motor assembly with three stators (first, second, and third stators) arranged orthogonally around a common rotor. Each stator generates magnetic fields in orthogonal directions, and their superimposition enables the rotor to produce multi-dimensional driving forces, eliminating the need for separate motors for each dimension while reducing overall weight
Solution Approach 2:
The single motor assembly is designed to perform multiple functions by generating driving forces in three orthogonal dimensions simultaneously. The rotor can rotate around three different axes (first, second, and third rotation axes) through the coordinated action of the three stators, allowing one motor to replace what would traditionally require three separate motors
2Adaptability or versatility
If multiple motors are configured to provide multi-dimensional power, then the precision machine can operate in multiple dimensions, but the energy consumption increases
Solution Approach 1:
By merging three motor functions into a single integrated motor assembly with shared components (common rotor, integrated control system), the patent reduces redundant energy consumption. The three stators work cooperatively with a single rotor, and the control system manages all three phases simultaneously, eliminating the energy overhead of operating three independent motor systems
3Adaptability or versatility
If multiple motors are configured to provide multi-dimensional power, then the precision machine can operate in multiple dimensions, but the number of components increases
Solution Approach 1:
The patent merges multiple drive components into a single integrated motor assembly. The three stators share a common rotor and magnetic field generation system, and the control system manages all three phases through a unified control architecture. This integration significantly reduces the number of discrete components compared to using three separate motors, simplifying the overall system structure
Solution Approach 2:
The single motor assembly is designed as a universal multi-functional unit that can generate driving forces in three orthogonal dimensions. The rotor serves multiple functions by being driven by all three stators simultaneously, and the bearing system supports rotation around multiple axes, reducing the need for separate support structures that would be required for multiple independent motors

AI summary
A motor includes a stator with a first stator, a second stator, and a third stator, each including at least one stator coil, and a rotor including a magnetic element, a first bearing, a second bearing, and a shaft, the stators generating a superimposed magnetic field together causing the magnetic element to rotate. When the magnetic element rotates in the first plane, the outer ring of the first bearing rotates. The center of the first bearing is located in a plane where the second bearing is located, and when the magnetic element rotates in the second plane, the inner ring of the second bearing rotates. A central axis of the shaft passes through the center of the first bearing; wherein the shaft is rotatably fixed to the first bearing and connected to the second bearing.
