Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If round coil groups are used in planar drive systems, then rotor rotation capability is improved, but linear translational motion becomes unsteady and jerky
Solution Approach 1:
The patent applies different coil group geometries to different functional requirements: round coil groups are used specifically for enabling rotor rotation, while rectangular coil groups are used for providing stable linear translational motion. This local differentiation allows each coil group type to optimize its performance for its intended purpose without compromising the other function.
2Stability of the object's composition
If rectangular and elongated coil groups are used in planar drive systems, then linear translational motion is improved, but rotor rotation capability is limited
Solution Approach 1:
The patent merges two different coil group geometries (round and rectangular/elongated) into a single planar drive system. The round coil groups provide rotation capability while the rectangular coil groups provide stable linear motion, and both work together in the same system to achieve combined functionality that neither geometry could provide alone.
3Device complexity
If a planar drive system uses单一 coil group geometry, then device complexity is reduced, but functional versatility is limited
Solution Approach 1:
The patent creates a universal planar drive system that can perform multiple functions (stable linear translational motion and rotor rotation) by integrating different coil group geometries. This multi-functional design allows the system to adapt to various processing requirements without needing separate drive systems for different motion types.

AI summary
A method is provided for processing an object using a planar drive system having at least one stator assembly with a plurality of coil groups for generating a stator magnetic field, a stator surface above the stator assembly, and at least one rotor with a plurality of magnet units for generating a rotor magnetic field. A processing element is arranged above the stator surface. The planar drive system has at least one rotational position, where the rotor can be rotated about an axis perpendicular to the stator surface. A spatial arrangement of the processing element is predetermined by the rotational position. The method comprises energizing the coil groups so a rotor with the object arranged on the rotor moves to the rotational position, energizing the coil groups so the rotor rotates, and processing the object with the aid of the rotor rotation, where the processing element acts upon the object.
