Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional ship voltage supply systems are used to provide desired electric target voltage and energy, then the electric consumer is supplied with adequate power, but the system becomes expensive and complex
Solution Approach 1:
The invention divides the voltage supply system into multiple independent automotive traction battery modules that can be individually connected in series or parallel configurations. This segmentation allows the system to meet different voltage and energy requirements while using standardized, commercially available modules, thereby reducing overall system complexity and cost.
Solution Approach 2:
The patent applies automotive traction battery modules designed for one purpose (automotive applications) to a different purpose (ship voltage supply). These universal modules can be configured in various series/parallel arrangements to provide different voltage and energy levels, eliminating the need for custom-designed ship-specific battery systems and reducing complexity.
2Ease of manufacture
If automotive traction battery modules are used to reduce costs, then the system becomes more cost-effective, but the modules deviate from the target voltage and energy requirements
Solution Approach 1:
The invention implements dynamic configuration of battery modules through series and parallel connections that can be adjusted based on the specific voltage and energy requirements of the electric consumer. This dynamic adaptability allows standardized automotive battery modules to be tailored to match diverse ship power requirements while maintaining cost-effectiveness.
Solution Approach 2:
The patent changes the electrical parameters (voltage and energy) by altering the connection topology of the battery modules. By connecting modules in series, the voltage increases; by connecting in parallel, the energy capacity increases. This parameter adjustment allows precise matching of target voltage and energy requirements using off-the-shelf automotive modules.
3Quantity of substance
If multiple traction battery module groups are connected in parallel to increase energy capacity, then the electric target energy is met, but the control system complexity increases
Solution Approach 1:
The invention introduces an intermediary control layer that manages multiple traction battery module groups. Each group can be independently controlled and monitored, allowing the system to scale energy capacity by adding parallel groups without proportionally increasing control complexity. The intermediary control structure coordinates between individual modules and the overall system requirements.
