Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple circuit boards are stacked to increase sensor element altitude, then the sensor elements can be positioned at appropriate altitudes, but size errors accumulate and manufacturing precision deteriorates
Solution Approach 1:
The invention divides the altitude adjustment function into modular connector components with standardized structures. The connector body, conductive terminals, and welding pads are segmented into functional units that can be precisely manufactured independently and assembled, eliminating the error accumulation inherent in stacking multiple circuit boards while maintaining manufacturing precision.
Solution Approach 2:
The invention changes the fundamental parameter of altitude adjustment from cumulative stacking (multiple circuit boards) to a single integrated connector structure with fixed dimensional parameters. The connector body height and terminal positioning are designed as controlled parameters that directly determine sensor element altitude without error accumulation, achieving precise positioning through parameter optimization rather than assembly accumulation.
2Manufacturing precision
If multiple circuit boards are stacked to increase sensor element altitude, then the sensor elements can be positioned at appropriate altitudes, but thermal expansion and cold contraction issues worsen
Solution Approach 1:
The connector employs composite material construction combining insulating materials for the connector body with conductive materials for the terminals. This composite structure provides differential thermal management where the insulating body minimizes thermal expansion effects while the conductive terminals maintain electrical stability, reducing overall structural instability during temperature variations compared to homogeneous circuit board stacking.
Solution Approach 2:
Instead of using multiple circuit boards (conductive layers) stacked together which amplify thermal expansion effects, the invention inverts the approach by using an insulating connector body as the primary structural element with conductive terminals embedded within. This inversion reduces thermal expansion accumulation and improves structural stability during temperature cycling.
3Reliability
If conductive terminals are bent to form welding pads, then signal attenuation is reduced, but manufacturing complexity increases
Solution Approach 1:
The conductive terminals are pre-bent into their final configuration with welding pads formed in advance during the connector manufacturing process. This preliminary action ensures optimal signal transmission geometry is achieved before assembly, reducing signal attenuation while the pre-formed structure actually simplifies subsequent assembly operations compared to post-assembly bending or complex multi-step forming processes.
