Solution Overview
Problem
Existing impregnation systems for stators in series production face challenges in efficiently handling and processing stators during large-scale industrial production, particularly in ensuring consistent resin application and curing across various stator designs and shapes.
Innovation Solution
An impregnation system with a circulating transport device featuring a conveyor belt that allows stators to be transported and rotated transversely, utilizing deflection areas and multiple levels to guide stators through impregnation, gelling, and curing areas, with rollers and rotating traction means for support and rotation, enabling efficient resin application and curing regardless of stator shape or size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional transport device is used for stators, then simple structure is maintained, but handling efficiency and impregnation consistency deteriorate
Solution Approach 1:
The transport device is segmented into multiple independent conveyor belts (first conveyor belt for feed area, second conveyor belt for return area) that can operate autonomously. Each conveyor belt handles specific transport tasks, allowing parallel processing of multiple stators and improving overall handling efficiency without requiring a complex integrated mechanism.
Solution Approach 2:
The conveyor belts are designed to perform multiple functions: transporting stators through feed and return areas, maintaining rotational movement during transport, and positioning stators in deflection areas. This multi-functionality improves handling efficiency while avoiding the need for separate specialized devices for each task.
2Manufacturing precision
If stators are transported without rotation, then simple transport mechanism is used, but impregnation uniformity deteriorates
Solution Approach 1:
The transport function and rotation function are merged into a single conveyor belt system. The conveyor belts are designed to simultaneously transport stators linearly through the feed and return areas while maintaining their rotational movement, eliminating the need for separate rotation mechanisms and achieving impregnation uniformity through continuous rotation.
Solution Approach 2:
Stators are set into rotational movement before entering the impregnation process. The conveyor belts maintain this preliminary rotation throughout transport, ensuring that the impregnation process occurs while stators are already in the optimal rotating state for uniform resin distribution, thereby improving impregnation uniformity.
3Adaptability or versatility
If complex handling is used for non-cylindrical stators, then handling capability improves, but processing time increases
Solution Approach 1:
The conveyor belt system is designed with universal handling capability that works for both cylindrical and non-cylindrical stators. The belts provide gentle support and rotation without requiring complex positioning mechanisms, allowing diverse stator shapes to be processed through the same streamlined workflow, improving adaptability without adding processing time.
Solution Approach 2:
The system uses dynamic rotation of stators on the conveyor belts rather than static positioning. This dynamic approach adapts to different stator shapes naturally, as the rotation ensures all surfaces are exposed to the impregnation process regardless of geometry, enhancing handling capability for various shapes while maintaining efficient continuous processing.
4Manufacturing precision
If single-level transport is used, then simple layout is maintained, but impregnation process completeness deteriorates
Solution Approach 1:
The system transitions from a single-level layout to a multi-level arrangement with conveyor belts operating at different heights. The first conveyor belt operates in the feed area at one level while the second conveyor belt operates in the return area at another level, allowing simultaneous execution of multiple process stages (transport, rotation, impregnation, curing) without spatial interference, ensuring process completeness.
Solution Approach 2:
The impregnation system is segmented into distinct functional areas (feed area, return area, deflection areas, curing areas) distributed across multiple levels. Each level handles specific process stages, allowing comprehensive impregnation processing to be completed through organized spatial segmentation without requiring an overly complex single-level layout.
