Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate special data connections are used for data transmission, then data communication reliability is improved, but device complexity and wiring effort increase
Solution Approach 1:
The patent combines power supply function and data transmission function into a single power supply network. The power lines serve dual purposes: delivering electrical power and carrying modulated data signals. This eliminates the need for separate special data connections, reducing wiring complexity while maintaining communication reliability through the integrated network.
Solution Approach 2:
The power supply network is designed to perform multiple functions simultaneously. Besides its primary function of power distribution, the network also serves as a data transmission medium. This multi-functionality reduces the number of separate systems needed, simplifying the overall device architecture and reducing wiring effort.
2Loss of information
If dedicated data connections are provided for all components, then data transmission quality is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent merges data transmission capabilities into the existing power supply infrastructure. By modulating data signals onto the power lines, the system eliminates the need for additional dedicated data wiring during manufacturing. This approach maintains data transmission quality while significantly improving ease of manufacture, as no separate data connection installation is required.
3Adaptability or versatility
If multiple special data connections are used, then data communication capability is improved, but loss of substance increases
Solution Approach 1:
The power supply network is designed to handle both power distribution and data transmission, eliminating the need for additional wiring material. The existing power lines carry both electrical energy and modulated data signals, reducing substance loss by avoiding redundant wiring while maintaining full data communication capability across all connected devices.
4Device complexity
If power supply network is used for data transmission, then device complexity is reduced, but electromagnetic radiation increases
Solution Approach 1:
The patent converts the potential harmful effect of electromagnetic radiation into a beneficial feature by using the same power supply network for both power delivery and data transmission. The modulated signals on the power lines utilize the existing electromagnetic field infrastructure, reducing the need for additional radiating components while maintaining data communication capability.

AI summary
The invention relates to a method and a device for data transmission on board a water vehicle using an onboard power supply system (20.1, 20.2). A central control unit (10) generates an instruction for a first consumer module (4.3, 4.5). The instruction is transmitted from the central control unit to a first head station (3.1) via a first control unit - head station data connection (21.1, 21.2). The first head station (3.1) converts the instruction into an instruction signal which can be transmitted via the power supply system (20.1, 20.2). The instruction signal is transmitted from the first head station (3.1) to a first coupling module (4.4) via a first head station - power line data connection (21.4), via the power supply system (20.1, 20.2) and via a first coupling module - power line data connection (21.10). The first coupling module (4.4) produces another instruction from the instruction signal, which can be transmitted via a data connection. The instruction is transmitted from the first coupling module (4.4) to the first electrical consumer module (4.3, 4.5) via a first coupling module - consumer data connection (21.6, 21.7).
