Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Ethernet transmitting apparatuses have a single signal transmitting path, leading to unstable connections and inaccurate data transmission when networks are unstable, limiting the ability to transmit necessary information effectively.
Innovation Solution
A transmitting apparatus that utilizes a transformer with a primary and secondary side to transmit data signals of different frequencies over the same transmission medium, enabling bi-directional communication and providing an additional signal path without increasing network lines, using a transformer, transmitting unit, and control unit to generate and transmit signals within distinct frequency ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single signal transmitting path is used between physical layer circuits, then the device complexity is reduced, but the reliability of data transmission deteriorates when the network is unstable
Solution Approach 1:
The patent divides the signal transmission into two separate paths: a first signal transmitting path for data signals and a second signal transmitting path for control signals. This segmentation allows independent transmission channels, so when one path experiences instability, the other path can still function, thereby improving overall transmission reliability without requiring a completely complex multi-path system.
Solution Approach 2:
The patent introduces a coupling circuit as an intermediary component that enables the control signal path to interact with the data signal path. The coupling circuit allows the control signals to be transmitted through the data signal transmitting path under certain conditions, providing an additional communication channel without directly complicating the primary transmission architecture.
2Ease of operation
If only one signal transmitting path is used, then the ease of operation is maintained, but the ability to accurately transmit control signals deteriorates
Solution Approach 1:
The patent segments control signals from data signals into separate transmitting paths. The second signal transmitting path is dedicated to control signals, ensuring they receive appropriate transmission treatment and protection. This segmentation enables accurate control signal transmission while maintaining simple operation through clear signal separation and dedicated handling procedures.
3Reliability
If the network line is increased to provide additional signal paths, then the reliability is improved, but the cost and device complexity increase
Solution Approach 1:
The patent makes the first signal transmitting path multi-functional by enabling it to carry both data signals normally and control signals when needed (through the coupling circuit). This universality allows the system to achieve reliable control signal transmission without requiring a completely separate physical network line, thereby improving reliability while avoiding the cost and complexity of additional network infrastructure.
Solution Approach 2:
The patent merges the control signal transmission capability into the existing data signal transmitting path through the coupling circuit. Instead of requiring entirely separate infrastructure, the system combines both signal types into one path when appropriate, reducing the need for additional network lines while maintaining reliable transmission through intelligent signal management.
