Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used in ship interior, then communication simplicity is improved, but signal transmission reliability deteriorates due to metal bulkheads causing signal loss
Solution Approach 1:
The patent introduces magnetic field communication as an intermediary transmission medium that can penetrate metal bulkheads. Instead of using traditional electromagnetic waves that are blocked by metal, the system uses magnetic fields generated by magnetic materials to transmit communication signals through the metal structures of the ship, thereby maintaining both simplicity and reliability.
Solution Approach 2:
The patent changes the physical parameter of the communication signal from traditional electromagnetic waves to magnetic fields. By utilizing magnetic field communication with magnetic materials, the system can transmit signals through metal bulkheads that would normally block electromagnetic waves, thus improving signal transmission reliability while maintaining ease of operation.
2Reliability
If wired communication is used in ship interior, then signal transmission reliability is improved, but device complexity increases due to extensive communication lines required
Solution Approach 1:
The patent replaces the mechanical wired communication system with a magnetic field-based wireless communication system. Instead of physically connecting devices through communication lines that must be routed through the entire ship interior, the system uses magnetic fields to transmit signals, eliminating the need for extensive wiring while maintaining reliable communication.
3Area of stationary object
If wired communication is used throughout the entire internal space, then communication coverage is improved, but installation cost increases due to extensive communication lines
Solution Approach 1:
The patent replaces the extensive wired communication infrastructure with magnetic field communication devices that can be strategically placed. These devices generate magnetic fields that penetrate metal bulkheads and provide communication coverage throughout the ship interior, eliminating the need to install communication lines throughout the entire internal space while reducing installation costs.
Solution Approach 2:
The magnetic field communication devices serve multiple functions: they generate magnetic fields for signal transmission, penetrate metal bulkheads, and provide wide-area coverage. This multi-functionality allows a single device to replace what would otherwise require extensive wiring infrastructure, thereby reducing installation costs while maintaining comprehensive communication coverage.
