Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If shielding is provided by a sheet metal part attached to the outside, then shielding is achieved, but assembly complexity increases and field assembly becomes difficult
Solution Approach 1:
The patent integrates the shielding function directly into the connector housing structure itself, merging the housing and shielding functions into a single component. This eliminates the need for separate sheet metal shielding parts and their associated attachment operations, thereby maintaining shielding effectiveness while significantly simplifying assembly procedures for field installation.
Solution Approach 2:
The connector housing is designed to serve multiple functions simultaneously: it provides mechanical support, guides wire pairs, and incorporates integrated shielding elements. This multi-functionality allows the housing to provide shielding protection without requiring additional dedicated shielding components, thus improving ease of assembly while maintaining shielding effectiveness.
2Reliability
If clamp-cutting technology is used to connect wires, then reliable connections are achieved, but device complexity increases
Solution Approach 1:
The clamp-cutting functionality is divided into multiple independent clamp-cutting devices, each responsible for a specific wire pair. This segmentation allows each device to be simple in structure while collectively providing reliable connections for all wire pairs, reducing the complexity of individual components while maintaining overall connection reliability.
Solution Approach 2:
The clamp-cutting devices are arranged in a three-dimensional configuration with subsets positioned above and below the substrate. This spatial arrangement in multiple dimensions allows for simplified individual device designs while achieving comprehensive wire connection and cutting functionality, thereby reducing overall device complexity while maintaining connection reliability.
3Object-generated harmful factors
If wire pairs are shielded from one another, then near-end crosstalk is minimized, but manufacturing complexity increases
Solution Approach 1:
The shielding structure is designed with local quality variations, providing different shielding configurations for different wire pairs based on their specific crosstalk requirements. This localized approach allows for effective near-end crosstalk minimization while avoiding the need for uniformly complex shielding structures throughout the entire connector, thereby simplifying manufacturing processes.
Solution Approach 2:
The shielding arrangement employs asymmetric configurations where wire pairs are shielded differently according to their positional requirements and crosstalk characteristics. This asymmetric design enables targeted crosstalk reduction without requiring symmetric complex shielding structures, thus reducing manufacturing complexity while maintaining effectiveness in minimizing near-end crosstalk.
4Reliability
If connectors are designed to meet Cat6A standards, then transmission performance is improved, but ease of assembly deteriorates
Solution Approach 1:
The connector is designed with pre-configured elements during manufacturing, including pre-positioned clamp-cutting devices, pre-integrated shielding structures, and pre-arranged wire pair routing paths. These preliminary actions taken during manufacturing eliminate the need for complex field assembly operations, allowing the connector to meet Cat6A performance standards while maintaining ease of field assembly.
Solution Approach 2:
The connector design incorporates self-aligning and self-assembling features that allow the components to automatically position themselves during assembly without requiring precise manual alignment or complex assembly procedures. This self-service capability enables the connector to achieve Cat6A transmission performance while significantly simplifying field assembly operations.

AI summary
The plug connector (1) has a substrate (2) and multiple clamping gumption devices (3a to 3g), which are arranged on the substrate for retaining wires. A subset of the multiple clamping gumption devices is arranged above the substrate, where another subset of the multiple clamping gumption devices is arranged below the substrate. Wiring flaps (4a,4b) are provided for introducing the wires in the clamping gumption devices in hinge manner. The plug connector is provided under specification of Category 6a.
