Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used in ships, then communication simplicity is improved, but signal loss occurs due to metal bulkheads
Solution Approach 1:
The patent introduces magnetic field communication as an intermediary method to enable communication through metal bulkheads. Instead of using traditional electromagnetic waves that are blocked by metal, the system uses magnetic fields that can penetrate metal structures, with magnetic communication modules installed on both sides of the bulkhead to establish communication paths through the metal barriers.
Solution Approach 2:
The patent changes the fundamental parameter of communication from electromagnetic waves to magnetic fields. By operating in the magnetic field domain rather than traditional radio frequency electromagnetic waves, the system overcomes the blocking effect of metal bulkheads while maintaining wireless communication simplicity.
2Reliability
If wired communication is used to overcome metal bulkhead interference, then signal transmission reliability is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent replaces the mechanical wired connection system with a magnetic field-based wireless communication system. Instead of physically running cables through metal bulkheads, the system uses magnetic communication modules that transmit data through magnetic fields, eliminating the need for complex wired installations while maintaining reliable signal transmission through metal structures.
3Adaptability or versatility
If wired communication is used throughout the ship, then communication coverage is improved, but installation and maintenance cost increase
Solution Approach 1:
The patent divides the ship's communication system into segmented magnetic communication zones. Instead of running continuous wired connections throughout the entire ship, magnetic communication modules are installed at strategic locations (such as on bulkheads and in communication zones) to create localized magnetic communication fields that cover specific areas, reducing the overall number of installation points while maintaining comprehensive coverage.
