Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable connectors experience signal degradation due to unequal time duration in high-frequency balance transmission, leading to noise, disconnection, and reduced quality in image and voice signals, as well as data loss during network communication.
Innovation Solution
A compact choke signal-adjusting device with a circuit board and series-disposed chokes in transmission circuits adjusts balance signals of unequal time duration to equal time duration, enhancing transmission quality by mitigating noise and disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-speed transmission is used to accelerate digital signals, then transmission speed is improved, but signal quality deteriorates due to matching impedance, crosstalk, transmission delay, and electromagnetic interference
Solution Approach 1:
The patent introduces a choke as an intermediary component inserted into the transmission circuit between adjacent pins. This choke acts as a mediator that suppresses electromagnetic interference and crosstalk by providing a high-impedance path for high-frequency noise, thereby improving signal quality without reducing transmission speed. The choke is positioned at critical locations where interference occurs most intensely.
2Device complexity
If simple transmission circuits are used in connectors, then device complexity is reduced, but signal transmission quality deteriorates due to unequal time duration in high-frequency balance transmission
Solution Approach 1:
The patent applies local quality by selectively placing chokes only in specific locations within the transmission circuit where interference and unequal time duration occur most intensely. Rather than complicating the entire circuit design, the choke is positioned at critical points between adjacent pins to locally suppress interference and equalize signal timing, maintaining overall circuit simplicity while improving signal quality.
3Reliability
If chokes are added to transmission circuits to equalize signal timing, then signal transmission quality is improved, but device complexity increases
Solution Approach 1:
The choke serves as a compact intermediary component that can be easily integrated into existing transmission circuits without requiring major redesign. By positioning the choke at specific locations in the signal path, it automatically equalizes timing and suppresses interference through its inherent electromagnetic properties, improving signal quality with minimal additional complexity.
