Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing is secured to the stator module through welding or curving the front plate, then the housing can be fixed in position, but the manufacturing process becomes complicated and positioning accuracy deteriorates
Solution Approach 1:
The front plate is integrated with the stator module as a single unified structure, eliminating the need for separate fixation operations such as welding or curving. This merging of components simplifies the manufacturing process while ensuring reliable housing positioning, as the housing is directly secured to the integrated front plate-stator assembly without requiring additional fixing steps.
2Reliability
If welding or curving operations are performed on the front plate, then the housing can be secured, but positioning accuracy and manufacturing precision deteriorate
Solution Approach 1:
By integrating the front plate with the stator module into a single structure, the invention eliminates thermal and mechanical distortions caused by welding or curving operations. This ensures that the housing maintains accurate positioning relative to the stator module without the precision losses that would result from subsequent fixation operations.
3Reliability
If separate fixing means are used to secure the housing to the stator module, then the housing can be fixed, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The integration of the front plate with the stator module eliminates the need for separate fixing means and operations. This reduces the number of assembly steps required to secure the housing, thereby increasing production speed and efficiency while maintaining reliable fixation of the housing to the stator module.
