Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electrical interconnects are used, then device simplicity is maintained, but electrical performance deteriorates at high data rates
Solution Approach 1:
The patent applies local quality by embedding lossy inserts at specific locations within the substrate - specifically in pockets positioned between contact channels and near socket contacts. These localized lossy regions provide targeted resonance absorption where electrical performance degradation occurs, without requiring the entire interconnect structure to be redesigned or made more complex.
Solution Approach 2:
The lossy inserts act as intermediary elements between the signal paths (socket contacts) and the substrate. These inserts mediate the electromagnetic field interactions by absorbing resonant energies that would otherwise propagate and cause performance degradation, thereby improving electrical performance without directly modifying the socket contacts or circuit boards.
2Reliability
If lossy inserts are added to the substrate, then resonance absorption improves, but manufacturing complexity increases
Solution Approach 1:
The lossy inserts are pre-positioned within molded pockets of the substrate during the substrate manufacturing process. This preliminary placement ensures that the inserts are correctly positioned relative to the contact channels and socket contacts before final assembly, eliminating the need for complex post-assembly alignment procedures and simplifying the overall manufacturing process.
Solution Approach 2:
The patent merges the lossy insert placement with the substrate molding process itself. By integrating the inserts into the substrate manufacturing workflow rather than treating them as separate assembly steps, the overall manufacturing complexity is reduced while still achieving the desired resonance absorption functionality.
3Reliability
If lossy material is used in pockets, then electrical resonance is absorbed, but material cost increases
Solution Approach 1:
The lossy material is applied locally only in the pocket regions where resonance absorption is needed, rather than throughout the entire substrate. This localized application minimizes the total quantity of lossy material required while still achieving effective resonance control and insertion loss management at the critical contact interface regions.
Solution Approach 2:
The patent uses partial action by placing lossy inserts in selected pockets rather than filling all available pockets. This selective placement provides sufficient resonance absorption to meet performance requirements without unnecessarily increasing material consumption or cost, achieving the minimum effective amount of lossy material needed.

AI summary
A socket connector includes a substrate having contact channels between upper and lower surfaces and pockets between the upper and lower surfaces between corresponding contact channels. The socket connector includes socket contacts received in corresponding contact channels. Each socket contact includes a contact body, an upper mating element extending to the upper surface to interface with a first electrical component, and lower mating element extending to the lower surface to interface with a second electrical component. The socket connector includes lossy inserts received in the pockets manufactured from lossy material capable of absorbing electrical resonance propagating through the substrate. The lossy inserts are separate and discrete from the substrate and are attached to the substrate in the pockets in proximity to the socket contacts.
