Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connectors for data communications face challenges with electromagnetic interference and limited bandwidth capabilities, especially as electronic devices require higher data processing and power transfer, leading to increased electromagnetic coupling and crosstalk issues.
Innovation Solution
The development of a multiple bandwidth connector with a housing featuring regularly spaced contact receiving channels and contacts with blade arms, attaching tails, and mounting areas that include non-conductive center portions for high bandwidth contacts and conductive center portions for low bandwidth contacts, allowing for closer blade spacing and reduced electromagnetic interference while maintaining compatibility with existing USB standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If connectors are miniaturized to reduce device size, then device form factor is improved, but electromagnetic coupling and crosstalk increase
Solution Approach 1:
The patent applies local quality by making the center portions of contact mounting areas non-conductive specifically for high bandwidth contacts, while maintaining conductive centers for low bandwidth contacts. This localized modification reduces electromagnetic coupling between adjacent high speed contacts without affecting the overall connector structure or low speed functionality.
Solution Approach 2:
The patent changes the electrical conductivity parameter of the contact mounting areas by introducing non-conductive center portions in high bandwidth contacts. This parameter change directly reduces electromagnetic interference while maintaining mechanical and electrical connection functionality.
2Speed
If data communication speed is increased, then bandwidth capability is improved, but electromagnetic interference and crosstalk worsen
Solution Approach 1:
The patent differentiates between high bandwidth and low bandwidth contacts by applying non-conductive center portions only to high bandwidth contacts. This local quality differentiation allows high speed data transmission while mitigating the electromagnetic interference that specifically affects high frequency signals.
Solution Approach 2:
The patent modifies the electrical properties of high bandwidth contacts by introducing non-conductive center portions, changing the capacitance and electromagnetic coupling characteristics specifically for high speed signal paths to reduce interference.
3Adaptability or versatility
If multiple connectors are added to provide high speed data and power, then functionality is improved, but device complexity and susceptibility to disconnection increase
Solution Approach 1:
The patent creates a universal connector design that can handle both high bandwidth data communication and power transfer through a single integrated interface. The connector accommodates different contact types (high bandwidth with non-conductive centers, low bandwidth with conductive centers) within one structure, eliminating the need for separate connectors.
Solution Approach 2:
The patent merges previously separate high speed data and power connectors into a single unified connector assembly. This consolidation integrates multiple functions into one interface, reducing the total number of connectors while maintaining all necessary capabilities.

AI summary
A multiple connector socket is able to interface to a low bandwidth connector and a high bandwidth connector. The low bandwidth connector facilitates a low bandwidth interface, such as USB 2.0, using a miniaturized connector having low bandwidth blade contacts 734, 738, 742, such as a micro USB 2.0 connector. The high bandwidth connector interposes high bandwidth blade contacts 732, 736, 740, 744 between the low bandwidth blade contacts for facilitating a high bandwidth interface, such a components of a DisplayPort interface. The high bandwidth blade contacts incorporate apertures to reduce electromagnetic coupling with the low bandwidth blade contacts. In one implementation apertures are not required on the low bandwidth blade contacts.
