Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power consuming devices are operated without planning on a marine vessel with finite power source capacity, then device operation flexibility is improved, but power source depletion occurs leading to operational failure
Solution Approach 1:
The system performs preliminary analysis of power consumption patterns by storing usage models that capture historical power usage data for various devices. Before executing a usage plan, the control system analyzes the plan against the stored usage model to predict power source performance and identify potential depletion risks in advance, allowing operators to adjust plans before committing resources.
Solution Approach 2:
The system implements continuous feedback by monitoring actual power consumption during operation and comparing it against predicted values from the usage model. The control system uses this feedback to dynamically adjust device operations, provide warnings about approaching power limits, and optimize power distribution to prevent depletion while maintaining operational flexibility.
2Reliability
If power consumption is strictly limited to prevent depletion, then power source sufficiency is improved, but device operation flexibility deteriorates
Solution Approach 1:
The system dynamically adjusts power allocation based on real-time conditions, device priorities, and remaining power source capacity. Rather than imposing static limits, the control system continuously optimizes power distribution to match actual operational needs, allowing flexible operation when power is abundant while automatically conserving power when reserves are low, thus maintaining both reliability and adaptability.
Solution Approach 2:
The system changes operational parameters of power-consuming devices based on power availability. The control system can adjust device operating modes, power consumption rates, and operational schedules dynamically, transforming device parameters to optimize the balance between power conservation and operational flexibility rather than simply on/off control.
3Productivity
If real-time power monitoring and analysis systems are implemented, then power consumption management is improved, but system complexity increases
Solution Approach 1:
The system employs self-service mechanisms where the control automatically manages power allocation based on pre-stored usage models and predefined device priorities. The control system performs autonomous analysis of usage plans against power source capacity and automatically implements optimization decisions without requiring constant human intervention, reducing the operational complexity burden on users while maintaining high management efficiency.
Solution Approach 2:
The system reduces real-time computational complexity by performing preliminary analysis and storing usage models in advance. Historical power consumption data and device characteristics are pre-processed and stored as usage models, allowing the control system to quickly evaluate usage plans by comparing against pre-computed models rather than performing complex real-time calculations, thus improving management efficiency while limiting system complexity.
Data Source
AI summary
A method for planning consumption of power by devices onboard a marine vessel from a power source having a finite capacity. The method includes storing a usage model within a memory system, where the usage model includes an amount of the power consumed by each of the devices over a time period. The method further includes receiving a usage plan for operating the marine vessel while the power source is limited to the finite capacity. The method further includes analyzing with a control system the usage plan in view of the usage model and generating a projected performance of the power source, wherein the projected performance indicates the ability of the power source to supply the power needed by the devices while operating the marine vessel according to the usage plan.
