Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stators in electromechanical systems, such as generators and motors, are continuous structures that encircle the entire rotor, making maintenance and repair difficult, requiring significant disassembly and occupying valuable space, especially in limited environments.
Innovation Solution
A segmented stator comprising separable stator segments that extend partway around the rotor, allowing individual segments to be removed radially without disassembling the entire stator, and incorporating a magnetic field generator to induce electrical current through electromagnetic interaction with a toothed rotor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a continuous annular stator is used, then the structural integrity and electromagnetic performance are improved, but the ease of maintenance and space requirements worsen
Solution Approach 1:
The stator is divided into multiple separable stator segments that can be independently removed. Each segment maintains the necessary structural integrity and electromagnetic functionality while allowing individual access to the rotor without requiring complete stator disassembly, thus resolving the contradiction between structural integrity and ease of maintenance.
2Reliability
If a continuous annular stator is used, then the electromagnetic performance is improved, but the space occupied increases
Solution Approach 1:
The stator is segmented into multiple separate units that can be arranged around the rotor. This segmentation allows for more flexible spatial arrangement and reduces the overall space occupied by the stator assembly while maintaining the necessary electromagnetic performance through proper positioning and design of each segment.
3Stability of the object's composition
If a continuous annular stator is used, then the structural stability is improved, but the accessibility to internal components worsens
Solution Approach 1:
The stator is divided into separable segments that can be independently removed to provide direct access to the rotor and internal components. Each segment is designed to maintain structural stability when in place, while the segmented nature allows easy removal and reinstallation, thus resolving the contradiction between structural stability and accessibility.
