Cable Connector Assembly With Layered Wire Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connector assemblies face challenges in accommodating thin cable thickness, particularly for high-speed signal transmission, as they often have a large circular cross-section that does not meet the requirements for thinner cables.
Innovation Solution
A cable connector assembly with a cable configuration that includes high-speed wires evenly distributed on both sides of a horizontal line, low-speed wires on one side, power wires on another side, and a detection and power supply wire in line, arranged to minimize mutual coupling and crosstalk, allowing for efficient signal transmission while maintaining a reduced thickness.

Engineering Contradiction Analysis
1Reliability
If the cable includes multiple wires enclosed in insulative layers with a circular cross-section, then the cable can transmit high-speed signals reliably, but the cable thickness becomes large and difficult to accommodate in thin connector assemblies
Solution Approach 1:
The patent transitions from a conventional circular cross-section cable layout to a flattened configuration where wires are arranged in layers along the thickness direction. The first and second insulative layers are positioned at different depths, with wires distributed across these layers to achieve signal transmission while reducing overall cable thickness to meet the 10mm constraint.
Solution Approach 2:
The cable is segmented into multiple insulative layers (first and second insulative layers) with wires distributed across these layers. High-speed wires are placed in the first insulative layer while low-speed wires are placed in the second insulative layer, allowing independent optimization of each layer for its specific signal requirements while collectively achieving reduced thickness.
2Length of stationary object
If wires are arranged closely together to reduce cable thickness, then the cable thickness requirement is met, but mutual coupling and crosstalk between wires increase
Solution Approach 1:
The patent segments wires into different functional groups placed in separate insulative layers: high-speed wires in the first layer and low-speed wires in the second layer. This vertical segmentation reduces lateral proximity between different signal types, minimizing mutual coupling and crosstalk while maintaining compact overall dimensions.
Solution Approach 2:
The patent employs asymmetric wire distribution within the flattened cable structure. High-speed wires are positioned with specific spacing and orientation in the first layer, while low-speed wires are arranged differently in the second layer. This asymmetric arrangement optimizes signal integrity for each wire type while accommodating the reduced thickness constraint.
