Overlapping Winding Arrangement for Positioning System Base Area Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning systems face limitations in efficiently utilizing their base area for two-dimensional positioning movements, as they often require larger overlapping magnetic fields to achieve precise control and extended positioning regions.
Innovation Solution
The positioning system incorporates overlapping x-winding and y-winding sections arranged parallel to the positioning plane, generating magnetic travelling fields with alternating north and south pole sections to enable efficient two-dimensional movement of the positioning carriage, allowing it to surpass the carriage support's edges and utilize the base area more effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional separate x and y winding sections are used, then the positioning system can achieve two-dimensional movement, but the base area utilization is inefficient and the positioning region is limited
Solution Approach 1:
The patent combines the x-winding section and y-winding section into an overlapping configuration where both windings occupy the same base area. The x-winding generates magnetic fields in the x-direction while the y-winding generates magnetic fields in the y-direction, and both fields coexist in the same spatial region, enabling efficient base area utilization and extended positioning coverage.
Solution Approach 2:
The patent transitions from separate spatial arrangements of x and y windings to an overlapping two-dimensional configuration. By arranging windings in the same base area with orthogonal orientations, the system achieves three-dimensional magnetic field control (x, y, and z components) from a two-dimensional winding layout, expanding the positioning region without increasing base area.
2Adaptability or versatility
If overlapping x and y winding sections are used, then the positioning region is extended and base area is optimized, but the magnetic field control complexity increases
Solution Approach 1:
The overlapping winding arrangement serves multiple functions simultaneously: the same base area generates both x-direction and y-direction magnetic fields, the windings provide both driving force and positioning control, and the magnetic field overlap creates a unified control region. This multi-functionality reduces the need for separate control systems for different positioning zones.
Solution Approach 2:
The patent controls the magnetic field characteristics by adjusting electrical parameters (current magnitude, frequency, phase) of the windings rather than changing the physical winding configuration. By varying these parameters, the system can dynamically control the magnetic field distribution, strength, and direction, simplifying the control of the overlapping field configuration.
3Area of stationary object
If magnetic fields are extended over greater areas, then the positioning carriage can move over multiple support modules, but the magnetic field strength may be diluted
Solution Approach 1:
The patent divides the extended positioning region into multiple support modules, each containing localized winding sections that generate strong magnetic fields in their respective areas. The overlapping configuration ensures that adjacent modules have complementary field distributions, creating a continuous strong field across the entire extended region without dilution.
Solution Approach 2:
The winding sections are arranged with asymmetric overlapping patterns where x-windings and y-windings are positioned to create non-uniform magnetic field distributions. This asymmetry allows certain regions to have enhanced field strength while maintaining overall extended coverage, optimizing the balance between field strength and coverage area.

AI summary
A positioning system has at least one positioning carriage which is variably mobile and positionable relative to a carriage support of the positioning system, whilst carrying out a positioning movement on a positioning plane defined by an xy cartesian co-ordinate system. The carriage support has at least one stator arrangement having a winding arrangement with an x-winding section for providing a magnetic x-travelling field, which can be moved in the direction of the x-axis of the xy co-ordinate system, and a y-winding section for providing a magnetic y-travelling field, which can be moved in the direction of the y-axis of the xy co-ordinate system. The positioning carriage is provided with a coupling arrangement which, during the positioning movement, magnetically interacts simultaneously with the x-travelling field and the y-travelling field.
