Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate gaskets are manually installed for sealing between the motor housing and inverter, then sealing function is achieved, but worker productivity decreases and assembly complexity increases
Solution Approach 1:
The sealing member is integrally molded with the inverter body as a single unified structure. The inverter body and sealing member form an integrated component where the sealing function is built-in rather than added separately, eliminating the need for manual gasket installation while maintaining reliable sealing performance
Solution Approach 2:
The sealing member is pre-formed as an integral part of the inverter body through injection molding. This preliminary integration of the sealing function into the main structure eliminates the need for separate sealing component installation during assembly, thereby improving worker productivity
2Reliability
If separate gaskets are manually installed for sealing, then sealing function is achieved, but assembly process becomes more complex and time-consuming
Solution Approach 1:
The sealing member and inverter body are merged into a single integrated component through integral molding. This consolidation reduces the total number of parts and eliminates the separate sealing installation step, simplifying the assembly process while ensuring reliable sealing
Solution Approach 2:
The sealing function is segmented from the main inverter body design but integrated through molding. The sealing member is formed as a distinct functional element within the integral structure, allowing specialized sealing design without requiring separate assembly operations
3Reliability
If separate gaskets are manually installed, then sealing is achieved, but production time increases due to manual intervention
Solution Approach 1:
The sealing member is pre-integrated into the inverter body structure during the molding process. This preliminary action of combining sealing and structural functions into one manufacturing step eliminates the need for time-consuming manual gasket installation, reducing overall assembly time while maintaining sealing reliability
