Engineering Contradiction Analysis
1Volume of moving object
If the differential pair contact elements are arranged with overlapping projections in a layered manner, then the connector achieves compact structure and high integration, but the differential pair becomes susceptible to external signal interference
Solution Approach 1:
The patent transitions from traditional planar arrangement to three-dimensional layered arrangement with intersecting projections. The differential pair contact elements in adjacent layers are positioned to intersect when viewed from the lateral direction, creating a twisted-pair like structure in 3D space. This dimensional change enables compact integration while achieving electromagnetic shielding through the intersecting geometry that cancels external interference fields.
Solution Approach 2:
The patent converts the potential harm of closely spaced layered structures (which create interference susceptibility) into a benefit by designing the intersecting projection arrangement. The intersecting geometry of differential pairs from adjacent layers creates opposing current loops that generate counteracting magnetic fields, thereby converting the compact layered structure from a source of interference vulnerability into an active shielding mechanism that benefits from the close spacing.
2Reliability
If traditional shielding boards are added to protect against interference, then signal integrity improves, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent implements self-service shielding where the differential pair contact elements themselves provide the shielding function. The intersecting projections of differential pairs from adjacent layers create inherent electromagnetic shielding through their geometry, eliminating the need for separate shielding boards. The structure shields itself by generating opposing magnetic fields that cancel external interference, making the shielding function intrinsic to the signal transmission structure.
Solution Approach 2:
The patent merges the signal transmission function and the electromagnetic shielding function into a single integrated structure. The differential pair contact elements serve dual purposes: transmitting differential signals and providing shielding against external interference through their intersecting arrangement. This consolidation eliminates the need for separate shielding components, reducing device complexity while maintaining signal integrity.
