Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fixing components with intermediate components are used to fix the neutral wire, then the neutral wire can be fixed, but the structure becomes complex and assembly stability deteriorates
Solution Approach 1:
The patent merges the neutral wire fixing function directly into the insulating base structure. The insulating base integrates both insulation and fixing functions, eliminating the need for separate fixing components and intermediate components. This consolidation simplifies the overall structure while improving assembly stability through a unified design.
Solution Approach 2:
The patent extracts the fixing function from separate fixing components and incorporates it directly into the insulating base. By taking out the need for intermediate components and separate fixing mechanisms, the design achieves a more straightforward structure that reduces complexity while maintaining or improving fixing reliability.
2Productivity
If separate fixing components are used for the neutral wire, then the neutral wire can be secured, but the manufacturing process becomes complex and productivity decreases
Solution Approach 1:
The insulating base combines multiple functions (insulation, support, and fixing) into a single component. This merging reduces the number of parts that need to be manufactured and assembled, thereby simplifying the manufacturing process and improving productivity through fewer assembly steps.
Solution Approach 2:
The insulating base serves multiple purposes: providing electrical insulation, mechanical support for the neutral wire, and structural integration with the stator core and windings. This multi-functionality reduces the need for separate dedicated components, simplifying both manufacturing and assembly processes.
3Reliability
If traditional fixing methods are used, then the neutral wire can be attached, but connection reliability deteriorates due to virtual connection risks from mechanical vibration
Solution Approach 1:
By integrating the fixing function into the insulating base itself, the neutral wire connection becomes part of the structural assembly rather than a separate attachment. This merging creates a more robust connection that better resists mechanical vibration, as the fixing is inherent to the base structure rather than relying on separate fastening components.
4Ease of operation
If no lead-out structure is provided for the neutral wire, then the stator structure remains simple, but ease of operation deteriorates due to difficulty in connecting to external circuits
Solution Approach 1:
The insulating base is designed with pre-integrated fixing structures and lead-out provisions for the neutral wire. This preliminary design of the fixing and connection features into the base structure itself eliminates the need for additional components, making external circuit connection convenient while maintaining structural simplicity.
