Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-size winding grooves are used in the stator core, then the manufacturing process is simple, but the power level of the stator core is limited and product expansion is restricted
Solution Approach 1:
The stator core is segmented into a stator yoke portion and multiple detachable stator teeth. The stator teeth can be independently configured with different sizes and spacing arrangements, allowing the winding groove dimensions to be adjusted by selecting appropriate stator tooth configurations without redesigning the entire stator core structure.
Solution Approach 2:
The stator teeth are designed to be detachably connected to the stator yoke portion, enabling dynamic reconfiguration of the stator core. Different numbers and arrangements of stator teeth can be assembled to create varying winding groove sizes, allowing the same basic structure to adapt to different power levels and product requirements.
2Productivity
If a single winding mode is used, then the winding process is standardized, but winding efficiency is affected and product expansion is limited
Solution Approach 1:
By segmenting the stator core into detachable stator teeth, the invention enables multiple winding configurations. Different combinations and arrangements of stator teeth create varied winding groove patterns, allowing multiple winding modes to be implemented using the same basic components, thereby improving both efficiency and adaptability.
Solution Approach 2:
The standardized stator tooth modules serve multiple functions: they maintain structural integrity, define winding groove boundaries, and enable different winding patterns. This multi-functionality allows a single component design to support various winding modes, improving productivity without sacrificing versatility.
3Productivity
If stator teeth are detachably connected to the stator yoke portion, then assembly efficiency is improved, but the structural complexity increases
Solution Approach 1:
The stator core is divided into separable components (stator yoke portion and stator teeth) that can be assembled independently. This segmentation allows for pre-fabrication and quality control of individual components, with simplified assembly through detachable connections, improving overall assembly efficiency despite the increased number of parts.
Solution Approach 2:
The stator teeth and stator yoke portion can be prepared separately with predetermined configurations before assembly. This preliminary preparation allows for optimization of each component independently and enables parallel manufacturing processes, which compensates for the additional assembly steps required by the detachable connection structure.
