Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the connector housing is secured by pressing it onto the stator insulation, then the assembly process is simple and quick, but the connector housing becomes detached during operation causing vibrations and material abrasion
Solution Approach 1:
The pressing element is designed as a resilient component that can be elastically deformed during assembly and then maintains a continuous pressing force on the connector housing. This dynamic elastic deformation allows the simple pressing assembly method while ensuring reliable connection during operation, resolving the contradiction between assembly simplicity and connection stability.
Solution Approach 2:
The resilient pressing element changes its physical state from undeformed to elastically deformed during the assembly process. This parameter change (deformation) enables the element to generate and maintain the necessary pressing force, ensuring the connector housing remains securely attached to the stator insulation throughout operation.
2Ease of operation
If the connector housing is fixed during assembly, then initial positioning is achieved, but vibrations occur during operation reducing service life
Solution Approach 1:
The resilient pressing element provides continuous dynamic adaptation through elastic deformation, maintaining optimal contact pressure between the connector housing and stator insulation throughout operation. This prevents vibrations and material abrasion, thereby extending the service life while keeping the assembly process simple.
Solution Approach 2:
The resilient pressing element acts as a cushioning mechanism that anticipates and compensates for operational vibrations and thermal expansions. By providing continuous elastic compensation, it prevents harmful vibrations and material abrasion before they can occur, extending the service life of the connector housing.
3Reliability
If latching mechanisms are used to secure the connector housing, then connection stability is improved, but the number of components and structural complexity increases
Solution Approach 1:
The pressing element is integrated as an essential component of the carrier element, merging the securing function into the existing structure. This eliminates the need for separate latching mechanisms while maintaining reliable connection stability, thereby reducing the number of components and simplifying the overall structure.
Solution Approach 2:
The resilient pressing element serves multiple functions: it secures the connector housing to the stator insulation, compensates for thermal expansions, and dampens vibrations. By combining multiple functions into a single component, it achieves reliable connection stability without increasing structural complexity.
