Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If diesel generators are used for power generation, then reliable power supply is achieved, but harmful emissions are produced
Solution Approach 1:
The patent replaces the mechanical combustion-based diesel generator system with a fuel cell system that uses electrochemical reactions to generate electricity. This substitution eliminates the combustion process that produces harmful emissions while maintaining reliable power generation capability through the fuel cell's continuous operation on hydrogen or other fuels.
Solution Approach 2:
The patent changes the fundamental operating parameters of the power generation system by transitioning from high-temperature combustion (diesel) to low-temperature electrochemical reactions (fuel cell). This parameter change fundamentally alters the emission profile while maintaining power output reliability.
2Reliability
If grid/shore power is used, then stable power supply is achieved, but portability and independence are reduced
Solution Approach 1:
The patent segments the power supply system into a portable fuel cell unit that can operate independently or connect to the grid. This segmentation allows the system to provide portability and independence when grid power is unavailable while maintaining the option for grid connection when stability is the priority.
Solution Approach 2:
The fuel cell power generation system is designed with multi-functionality to operate in multiple modes: standalone portable operation, grid-connected operation, and hybrid mode. This universality allows the same system to provide both portability and grid-stability benefits depending on operational requirements.
3Object-generated harmful factors
If fuel cell power generation is implemented, then zero-emission operation is achieved, but system complexity increases due to integration with batteries and inverters
Solution Approach 1:
The patent merges the fuel cell system with battery storage and inverter components into an integrated hybrid power system. This combination allows the fuel cell to handle base load and the battery to handle peak demands, simplifying overall system management while maintaining zero-emission operation during fuel cell generation.
Solution Approach 2:
The patent introduces a controller as an intermediary that manages the complex interactions between the fuel cell, battery, and inverter. This controller coordinates power flow, manages charging/discharging cycles, and optimizes system operation, thereby reducing the perceived complexity for the user while enabling sophisticated zero-emission power management.
4Reliability
If battery storage is added to the system, then power reliability is improved, but system weight and volume increase
Solution Approach 1:
The patent implements a partial battery storage solution rather than full capacity storage, sizing the battery to handle only peak demand periods and transient loads. This partial action approach provides sufficient power reliability improvement while minimizing the weight penalty of the battery system.
Solution Approach 2:
The battery system operates in periodic cycles, charging during periods when the fuel cell is generating excess power and discharging during peak demand periods. This periodic operation pattern maximizes the reliability benefit of the battery while minimizing its size and weight requirements.
