Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing round stators are complex and time-consuming, requiring intricate mechanics to shape wound pole teeth into a coherent, ring-shaped structure.
Innovation Solution
A method involving a rolling device with a groove system where wound pole teeth are inserted and formed into a ring shape, using a groove with an introduction section and a ring section to create a round stator structure, which is then held together and further processed to form a finished unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual rounding of wound pole teeth is performed to produce a round stator structure, then the stator can be formed with traditional methods, but the procedure becomes complex and time-consuming
Solution Approach 1:
The patent replaces complex manual rounding mechanics with a rolling device that uses a grooved roller to automatically form the round stator structure. The groove in the roller guides and shapes the pole teeth into a round configuration through rolling motion, eliminating the need for intricate manual rounding mechanisms.
Solution Approach 2:
The grooved roller is designed to automatically guide and shape the pole teeth into a round structure through its own geometry. The groove profile self-determines the final round shape of the stator, eliminating the need for additional complex forming mechanisms or manual intervention.
2Shape
If complex mechanics are used to manually round wound pole teeth, then a round stator structure can be produced, but the production time and effort increase significantly
Solution Approach 1:
The patent replaces time-consuming manual rounding operations with an automated rolling device. The grooved roller quickly forms the round stator structure in a single rolling motion, dramatically reducing the time and effort required compared to traditional manual methods.
Solution Approach 2:
The groove is pre-formed in the roller with the exact profile needed to create the round stator structure. This preliminary preparation of the forming tool allows for rapid, repeatable production of round stators without requiring complex real-time adjustments during the forming process.
3Stability of the object's composition
If wound pole teeth are assembled into a coherent row and then manually rounded, then the stator structure can be formed, but complex assembly and forming mechanics are required
Solution Approach 1:
The patent combines the assembly and forming operations into a single integrated process. The grooved roller simultaneously guides the coherent row of pole teeth and forms them into a round structure in one continuous motion, eliminating the need for separate assembly and forming mechanisms.
Solution Approach 2:
The grooved roller acts as an intermediary tool that receives the coherent row of pole teeth and transforms them into a round structure. The groove profile serves as the mediating geometry that converts the linear arrangement of pole teeth into a circular configuration without requiring complex direct manipulation.

AI summary
The invention relates to a method for producing a round stator. According to the invention, wound pole teeth are inserted into the insertion section of a rolling device to form a pole tooth row and the pole tooth row is pushed into the ring section of the rolling device reproducing the round end shape of the stator. Finally, the generated round stator structure is removed from the rolling device while being held together. The invention further relates to a rolling device for use in such a method.
