Adapter Module for Connecting Stator Windings to Power Supplies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly technologies for connecting stator windings of electric motors to power supplies are limited to standardized modular series, making it difficult to connect components from different series without redesigning or retooling machines, especially when suppliers become unavailable.
Innovation Solution
An adapter module with a third intermediate connector is used to connect box-like connectors of different modular series by coupling the first connector to the second connector, allowing for stable and easy assembly of stator windings to power supplies using known technologies and machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connectors of different modular series are connected, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces an adapter module as an intermediary component that connects connectors from different modular series. The adapter module includes a first adapter body with a first connector receptacle and a second adapter body with a second connector receptacle, enabling compatibility between different connector types without directly modifying the original connectors.
Solution Approach 2:
The connection assembly is segmented into distinct modular components: the first connector, the adapter module (which can be further divided into first and second adapter bodies), and the second connector. This segmentation allows each component to be independently designed, manufactured, and assembled, facilitating flexibility in connecting different modular series while maintaining overall system organization.
2Manufacturing precision
If dedicated assembly machines are used for each connector type, then manufacturing precision is improved, but productivity decreases
Solution Approach 1:
The adapter module is designed with universal compatibility to work with multiple connector types from different modular series. This multi-functionality allows a single adapter module design to accommodate various connector configurations, enabling assembly machines to handle different connector types without requiring dedicated equipment for each type, thereby improving machine utilization and productivity.
3Ease of manufacture
If standardized modular series are used, then ease of manufacture is improved, but adaptability worsens
Solution Approach 1:
The adapter module serves as a mediator that bridges standardized modular connector series. By introducing this intermediate component, the system maintains the manufacturing advantages of standardized connectors while achieving adaptability across different series. The adapter module itself can be manufactured using standard processes, preserving ease of manufacture while enabling connector interchangeability that would otherwise require custom manufacturing.
