Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operation management device cannot adapt to changes in maintenance or power generation efficiency requests, then the system structure remains simple, but the convenience and adaptability of the power generation system deteriorates
Solution Approach 1:
The operation management device dynamically changes its control strategy based on the type of request received. When a maintenance efficiency request is detected, it prioritizes engine power generator operation; when a power generation efficiency request is detected, it prioritizes fuel cell power generator operation. This dynamic adaptation resolves the contradiction by making the system both adaptable to changing requests and convenient for users to obtain optimal performance.
Solution Approach 2:
The device changes operational parameters (which generator to prioritize) based on the request type. By detecting whether the request emphasizes maintenance efficiency or power generation efficiency, the system adjusts its operation mode accordingly, enabling adaptability while maintaining ease of operation through automated parameter adjustment.
2Adaptability or versatility
If the operation management device selectively operates engine or fuel cell generators based on request type, then the adaptability and convenience improve, but the device complexity increases
Solution Approach 1:
The operation management device segments the control logic into distinct pathways based on request type. It separates the handling of maintenance efficiency requests from power generation efficiency requests, with dedicated processing for each scenario. This segmentation enables high adaptability while managing complexity through structured, modular control logic.
Solution Approach 2:
The device incorporates feedback mechanisms to detect the type of request (maintenance efficiency or power generation efficiency) and adjusts its operation accordingly. This feedback-based control enables the system to adapt to changing requests without requiring complex manual intervention, as the system automatically senses and responds to operational requirements.
3Ease of repair
If the system prioritizes maintenance efficiency using engine power generator, then the maintenance efficiency improves, but the power generation efficiency deteriorates
Solution Approach 1:
The system dynamically switches between prioritizing maintenance efficiency and power generation efficiency based on the detected request type. When maintenance efficiency is prioritized, the engine power generator is operated; when power generation efficiency is prioritized, the fuel cell power generator is operated. This dynamic switching resolves the contradiction by allowing the system to optimize for one parameter at a time based on operational requirements.
Solution Approach 2:
The operation management device changes the operational parameter of which generator type to prioritize based on the request. By switching between engine power generator (for maintenance efficiency) and fuel cell power generator (for power generation efficiency), the system resolves the contradiction through parameter changes that align with current operational goals.
4Productivity
If the system prioritizes power generation efficiency using fuel cell power generator, then the power generation efficiency improves, but the maintenance efficiency deteriorates
Solution Approach 1:
The system dynamically adjusts its operational focus based on the detected request type. When power generation efficiency is the priority, it operates the fuel cell power generator; when maintenance efficiency is the priority, it operates the engine power generator. This dynamic adjustment resolves the contradiction by allowing the system to optimize for power generation efficiency when needed while accepting the trade-off in maintenance efficiency.
Solution Approach 2:
The operation management device changes the operational parameter of generator selection based on whether power generation efficiency or maintenance efficiency is prioritized. By switching between fuel cell power generator and engine power generator, the system resolves the contradiction through parameter changes that match current operational requirements.
