Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wireless communication systems are used, then device mobility and ease of installation are improved, but electromagnetic interference reliability and security are worsened
Solution Approach 1:
The patent introduces a hybrid communication architecture where wireless transceivers serve as intermediaries that receive data over shielded wired connections and retransmit it wirelessly. This mediator approach allows the system to leverage the security and EMI immunity of wired connections while maintaining the mobility and ease of wireless operation, effectively resolving the contradiction between reliability and ease of installation.
2Ease of operation
If conventional wireless communication systems are used, then device mobility is improved, but security is worsened
Solution Approach 1:
The wireless transceiver acts as a security intermediary by receiving all data transmissions through physically secure wired connections. The transceiver then handles wireless communication, creating a security boundary where sensitive data never暴露在 omnidirectional wireless signals, thus maintaining both mobility and security.
Solution Approach 2:
The system segments the communication function into two distinct parts: a wired segment for secure data transmission and a wireless segment for mobility. This segmentation allows each part to optimize for its specific function while mitigating the weaknesses of the other.
3Reliability
If traditional wired communication systems are used, then deterministic performance and physical security are improved, but installation complexity is worsened
Solution Approach 1:
The wireless transceiver serves as an intermediary that simplifies installation by eliminating the need for complex wired connections at mobile devices. Only the fixed transceiver requires wired infrastructure, while mobile devices can move freely, thus reducing installation complexity while maintaining deterministic performance through the wired-backhaul.
4Object-affected harmful factors
If star topology wired systems are used, then physical security is improved, but cable bundle complexity is worsened
Solution Approach 1:
The system segments the cable infrastructure requirement, concentrating all cable connections at the fixed wireless transceiver while mobile devices require no cable connections. This segmentation maintains physical security through shielded cables at the infrastructure point while eliminating cable management complexity at mobile device locations.
