Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom-designed stators and electrical connections are used for each rotary electrical machine configuration, then the machine can be adapted to specific uses and phase configurations, but production costs increase and standardization becomes difficult
Solution Approach 1:
The electrical connection system is segmented into modular components: a standardized stator body with notches, separate phase connectors that can be configured in different patterns (star, delta, etc.), and interchangeable terminal arrangements. This allows the same stator to be adapted to different phase configurations by simply reconfiguring the connector components rather than designing custom stators for each application.
Solution Approach 2:
The standardized stator body with uniformly spaced notches is designed to be universally compatible with multiple phase configurations (3-phase, 4-phase, 5-phase, etc.). The same basic stator structure can serve different functions by changing the connector arrangement, eliminating the need for custom-designed stators for each machine type and reducing production costs through economies of scale.
2Adaptability or versatility
If custom-designed stators are produced for each rotary electrical machine, then specific electrical connection requirements are met, but production complexity and variety of components increase
Solution Approach 1:
The electrical connection system is divided into independent modular elements: a standardized stator body with notches, separate phase connectors, and configurable terminals. This segmentation allows different connection configurations to be achieved by assembling different connector combinations with the same stator, reducing the number of unique stator designs needed.
Solution Approach 2:
The phase connector configuration is made dynamic and reconfigurable rather than fixed. The connector can be adapted to different phase arrangements (star, delta, series, parallel) by changing the connection pattern, allowing a single standardized stator design to serve multiple electrical configuration requirements without increasing device complexity.
3Ease of manufacture
If standardized stator production is implemented, then production costs decrease and manufacturing is simplified, but adaptability to different phase configurations and uses may be limited
Solution Approach 1:
The standardized stator body is designed with universal features including uniformly spaced notches and standardized terminal positions that accommodate multiple phase configurations. This universal design enables the same stator to be used across different applications (3-phase, 4-phase, 5-phase machines) by simply changing the connector arrangement, maintaining both standardization benefits and configurability.
Solution Approach 2:
The electrical connection system is segmented into the standardized stator body and separate reconfigurable phase connectors. This segmentation allows the stator to be produced in large quantities with standardized features, while the connectors can be configured differently to meet specific application requirements, thus maintaining adaptability without compromising manufacturing standardization.
