Engineering Contradiction Analysis
1Object-affected harmful factors
If physical one-way data transmission is implemented by cutting the reception line, then external intrusion is fundamentally prevented, but data loss occurs and transmission reliability cannot be ensured
Solution Approach 1:
The network communication function is segmented into one-way input module units, one-way output module units, and two-way module units that can be independently mounted in slots. This segmentation allows the system to maintain physical one-way transmission security while adding feedback capabilities through separate feedback processing modules that monitor transmission status without compromising the unidirectional data flow security.
Solution Approach 2:
A feedback processing module is introduced that receives feedback signals from the one-way transmission path and transmits control signals back to the transmission side through a separate feedback channel. This feedback mechanism enables the transmission side to know the reception state and adjust transmission parameters, ensuring data reliability while maintaining physical one-way transmission security.
2Device complexity
If conventional 1:1 communication is used in physical one-way transmission, then simple configuration is achieved, but N:M communication requires additional relay servers and complicated network structure
Solution Approach 1:
The module units are designed with universal functionality to operate in both one-way and two-way communication modes. Each module unit can function as an input unit, output unit, or two-way unit depending on configuration, and can be mounted in various slot combinations to achieve different communication topologies including 1:1, N:1, 1:N, and N:M configurations without requiring different hardware architectures or relay servers.
Solution Approach 2:
The system employs dynamic slot mounting and configuration where module units can be flexibly assigned to different slots and reconfigured based on communication requirements. This dynamic configurability allows the same physical hardware to adapt to different communication patterns (1:1, N:M, etc.) by changing the logical configuration rather than requiring physical restructuring or additional relay infrastructure.
3Reliability
If buffer size and transmission speed are adjusted in physical one-way transmission, then some data loss is mitigated, but the solution is imperfect because the transmission side cannot know the reception state
Solution Approach 1:
A feedback processing module is introduced that receives feedback signals from the one-way transmission path and transmits control signals back to the transmission side through a separate feedback channel. This feedback mechanism enables the transmission side to know the reception state and adjust transmission parameters, ensuring data reliability while maintaining physical one-way transmission security.
Solution Approach 2:
The system implements self-service through automatic feedback processing where the feedback processing module autonomously monitors transmission status, generates appropriate control signals, and adjusts transmission parameters without requiring manual intervention. This self-regulating mechanism continuously optimizes transmission reliability based on real-time reception feedback.
