Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transmission channels are connected to enable comprehensive device communication, then communication coverage is improved, but the risk of system-wide failure due to short circuits increases
Solution Approach 1:
The communication network is divided into multiple independent transmission channels (first transmission channel and second transmission channel), where each channel operates separately. The third device connects these channels but prevents short-circuit state propagation, ensuring that a failure in one channel does not affect the other channels. This segmentation approach maintains comprehensive communication coverage while reducing system-wide failure risk.
Solution Approach 2:
The third device serves as an intermediary between the first and second transmission channels. It electrically connects the channels to enable comprehensive communication, but simultaneously isolates short-circuit states through its internal design (using impedance components), preventing failure propagation while maintaining channel connectivity.
2Ease of operation
If transmission channels are electrically connected to enable device communication, then communication capability is improved, but the propagation of short-circuit states between channels increases
Solution Approach 1:
The third device acts as an intermediary that electrically connects the first and second transmission channels to enable communication capability, while its internal impedance components prevent the propagation of short-circuit states between channels. This allows the system to maintain communication functionality without the harmful effect of failure propagation.
Solution Approach 2:
The third device exhibits different electrical properties for different signal types: it allows normal communication signals to pass through while blocking short-circuit state propagation. This local quality differentiation enables the device to simultaneously provide communication capability and prevent harmful factor propagation.
3Device complexity
If a single communication line is used to connect all devices, then system complexity is reduced, but the impact of short circuits on the entire system increases
Solution Approach 1:
Instead of using a single communication line, the system is divided into multiple transmission channels with independent pathways. The third device connects these segmented channels while preventing short-circuit propagation, thereby reducing the impact of short circuits on the entire system while maintaining manageable complexity through modular architecture.

AI summary
A communication network system (90) includes a first transmission channel (50), a second transmission channel (60), a first device (70), a second device (20), and a third device (10). The second transmission channel (60) is different from the first transmission channel (50). The first device (70) is connected to the first transmission channel (50) and is not connected to the second transmission channel (60). The second device (20) is connected to the second transmission channel (60) and is not connected to the first transmission channel (70). The third device (10) electrically connects the first transmission channel (50) and the second transmission channel (60). The third device (10) does not transmit a short-circuit state occurring in one of the first transmission channel (50) and the second transmission channel (60) to a transmission channel other than the one of the first transmission channel (50) and the second transmission channel (60), thereby enabling communication between devices connected to the transmission channel other than the one.
