Cable Connector Coaxial Contact Arrangement for Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable connectors are limited by the geometric arrangement of contacts, which constrains bandwidth due to the physical size constraints, making it difficult to accommodate the increasing data transmission demands of the Internet of Things (IoT) era.
Innovation Solution
A cable connector design that positions a higher density of contacts coaxially along or in parallel with the major axis of the connector, allowing for a greater number of contacts within a compact diameter, enabling efficient data transmission across multiple channels by geometrically aligning contacts instead of stacking them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If contacts are arranged in a lateral or transverse fashion along an edge of a connector, then the connector can be manufactured with standard geometries, but the number of contacts is limited by the width of the connector
Solution Approach 1:
The patent transitions from traditional lateral/transverse contact arrangement (2D plane arrangement along the width) to a coaxial arrangement where contacts are positioned along the major axis (longitudinal dimension). This dimensional change allows contacts to be packed more densely along the length of the connector rather than being constrained by the width, thereby increasing the number of contacts without proportionally increasing the connector width.
Solution Approach 2:
The patent employs a nested tiered structure where multiple tiers of contacts are arranged concentrically along the major axis. Each tier contains multiple contacts arranged around the circumference, and tiers are stacked along the axis. This nesting approach maximizes the use of available space by utilizing both radial and axial dimensions, allowing a high density of contacts within a compact connector volume.
2Quantity of substance
If the number of contacts is increased to accommodate more data channels, then bandwidth capacity increases, but the connector size must be enlarged
Solution Approach 1:
The nested tiered structure allows multiple tiers of contacts to be stacked concentrically within the connector body. Each tier is positioned at a different radial distance from the center axis, and tiers are spaced along the major axis. This nesting enables a large number of contacts to be packed into a compact volume by efficiently utilizing the three-dimensional space within the connector, rather than requiring a linear expansion of connector size.
Solution Approach 2:
By arranging contacts along the major axis in multiple tiers rather than spreading them laterally, the patent utilizes the longitudinal dimension more effectively. This allows the connector volume to remain compact while accommodating more contacts, as the contacts are distributed along the axis rather than requiring increased width or height.
3Quantity of substance
If contacts are positioned coaxially along the major axis to maximize contact density, then bandwidth increases, but the manufacturing complexity increases
Solution Approach 1:
The connector is divided into multiple discrete tiers, each containing a specific number of contacts arranged around the circumference. Each tier can be manufactured and positioned as a separate module, which simplifies the overall manufacturing process. The segmentation into tiers allows for standardized production of each tier unit, reducing the complexity of manufacturing the entire multi-contact connector as a single complex component.
Solution Approach 2:
The nested tiered structure provides a modular architecture where each tier can be manufactured independently and then assembled into the final connector. This modularity reduces manufacturing complexity by breaking down the complex task of positioning many contacts into simpler, repeatable steps of creating and assembling tiers. The self-aligning nature of concentric nesting also simplifies assembly precision requirements.

AI summary
A cable connector includes a male connector and a female connector. The male connector has a plurality of contacts disposed perimetrically or circumferentially coaxially along major axes of at least one peripheral surface or perimeter of the male connector. The female connector has a plurality of contacts disposed complementarily coaXially along major axes of at least one interior peripheral surface or perimeter of the female connector. Insertion of the male connector into the female connector allows for greater connectivity between cables because more contacts are accommodated coaXially along the connector length than the transverse dimension, as currently seen in the art. Greater bandwidth is therefore accommodated over a greater number of channels.
