Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable assemblies face challenges in achieving a low profile mating interface and high-speed signal transmission, with increased height and complexity in PCB layout due to the arrangement of PCBs and conductive pads.
Innovation Solution
A cable assembly design featuring a metallic case with a terminal module, metallic clips, and a cable connected to PCBs, along with a latch mechanism and metallic shell, which allows for a compact and efficient high-speed signal transmission while maintaining a lower profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a pair of PCBs are arranged paralleled in a vertical direction to achieve high-speed signal transmission, then the signal transmitting speed is improved, but the height of the mating interface is increased
Solution Approach 1:
The patent transitions from a vertical arrangement of PCBs (increasing height) to a horizontal arrangement where multiple PCBs are disposed side-by-side. This dimensional change allows high-speed signal transmission capabilities to be maintained while reducing the height of the mating interface to meet low-profile requirements.
Solution Approach 2:
The patent divides the connection interface into multiple independent PCBs arranged horizontally, with each PCB containing a subset of conductive pads. This segmentation allows the total number of signal paths to be maintained for high-speed transmission while distributing them across multiple smaller units that collectively occupy less vertical space.
2Speed
If more conductive pads are formed on the PCB to increase signal transmitting speed, then the signal transmitting speed is improved, but the layout of the printed circuit board becomes more difficult to design
Solution Approach 1:
The patent segments the total required conductive pads across multiple separate PCBs rather than concentrating them on a single large PCB. Each individual PCB has a manageable number of pads and simpler routing requirements, making layout design more straightforward while the collective assembly provides the necessary high-speed signal transmission capacity.
