Stator Electrical Connection Kit for Parallel Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing time of rotating electrical machine stators is increased due to the sequential processes of serializing coils and connecting poles, which can be time-consuming.
Innovation Solution
An electrical connection kit comprising superimposed and electrically insulated conductive elements is used to form an electrical connection circuit for each pole of each phase, allowing for simultaneous connection of coils and poles on opposite sides of the stator, reducing the need for sequential soldering and insulation operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sequential soldering and insulation operations are used to connect coils and poles, then reliable electrical connections are achieved, but manufacturing time is significantly increased
Solution Approach 1:
The patent divides the stator connections into two independent segments: coil serializations on the first side and pole connections on the second side. This segmentation allows both operations to proceed simultaneously without interfering with each other, eliminating the sequential dependency that caused time delays while maintaining connection reliability through dedicated connection kits for each segment
Solution Approach 2:
The patent utilizes the third dimension by placing connection operations on opposite sides of the stator (first side vs. second side). This spatial separation enables parallel processing of coil connections and pole connections simultaneously, transforming a time-sequential process into a space-parallel process without compromising electrical connection integrity
2Reliability
If multiple sequential connection operations are performed, then complete electrical connectivity is achieved, but production efficiency is reduced
Solution Approach 1:
The patent implements preliminary action by preparing and positioning connection kits on both sides of the stator before actual connection operations begin. The connection kits are pre-assembled with conductive elements and insulation materials, allowing immediate connection execution without delays for preparation during the manufacturing process, thus enhancing both connectivity reliability and production efficiency
Solution Approach 2:
The patent ensures continuity of useful action by enabling simultaneous uninterrupted connection operations on both sides of the stator. While coil serializations proceed on the first side, pole connections occur concurrently on the second side, maximizing productive utilization of manufacturing resources and eliminating idle time between operations, thereby improving production efficiency without sacrificing electrical connectivity
