Motor Winding Insulation Guide for Safer Conductor Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric motor designs with complex and costly guide means for winding conductors are prone to damage and electrical shorts, and lack efficient guidance and connection mechanisms, leading to increased production costs and complexity.
Innovation Solution
The integration of a guide means groove system within the fitting, allowing for axial guidance of winding conductor sections, separation to prevent shorts, and easy connection to other components, along with a modular insulating element formed from plastic or ceramic materials, which can be easily attached to existing fittings without redesign.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guide means are created by recesses in the fitting itself, then winding conductors can be guided, but manufacturing becomes very costly and complex and sharp edges may damage conductors
Solution Approach 1:
The patent divides the guide function into a separate component (guide element) rather than integrating it into the fitting. The guide element is a distinct segment that can be manufactured independently and attached to the fitting, allowing each component to be optimized separately for its specific function.
Solution Approach 2:
The guide element acts as an intermediary component between the fitting and the winding conductors. It provides the necessary guidance and protection functions without requiring the fitting itself to have complex recesses, thereby simplifying fitting manufacturing while maintaining conductor protection.
2Ease of operation
If guide elements are integrated into the fitting, then conductor guidance is achieved, but the overall device complexity increases
Solution Approach 1:
The guiding function is segmented into a separate guide element that can be easily attached to the fitting. This segmentation allows the fitting to maintain its simple structural design while the guide element provides the necessary conductor routing capabilities.
Solution Approach 2:
The guide element serves multiple functions: it guides the winding conductors, protects them from damage, and can be universally attached to different fitting types. This multi-functionality in a single separate component reduces overall device complexity compared to integrating multiple features into the fitting itself.
3Manufacturing precision
If multiple guide elements are formed in each groove, then proper guidance of multiple winding conductors is achieved, but manufacturing complexity increases
Solution Approach 1:
Multiple guide elements are combined into a single integrated guide component that can be manufactured as one piece. This merging approach maintains the precise alignment and guidance capabilities for multiple winding conductors while simplifying manufacturing compared to creating and assembling multiple separate guide elements.
