Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the microbial reactor processes heterogeneous feed or insufficient supply, then the treatment capacity is maintained, but the microbial degradation efficiency deteriorates and recovery cost increases
Solution Approach 1:
The system employs a feedback control mechanism where the state of microbial degradation is continuously monitored and used to adjust the supply of reformed material. This ensures that the microbial reactor maintains optimal operating conditions even when processing heterogeneous feed, preventing efficiency deterioration while preserving treatment capacity
Solution Approach 2:
The supply amount and timing of reformed material are dynamically adjusted based on the detected state of microbial degradation. This dynamic adaptation allows the system to maintain reliable microbial degradation efficiency while handling variable feed characteristics without compromising treatment capacity
2Reliability
If the supply amount of feed is insufficient, then the microbial reactor remains stable, but the treatment productivity deteriorates
Solution Approach 1:
The feedback control system monitors microbial degradation state and adjusts feed supply accordingly, allowing the system to increase productivity while maintaining stability by responding to real-time reactor conditions rather than using fixed supply rates
Solution Approach 2:
The system changes the parameters of feed supply (amount and timing) based on the detected microbial degradation state, enabling the reactor to operate at higher productivity levels while maintaining stability through adaptive parameter adjustment
3Adaptability or versatility
If the properties of feed supplied to the microbial reactor are heterogeneous, then the system can handle diverse waste, but the microbial degradation efficiency deteriorates
Solution Approach 1:
The feedback mechanism continuously monitors the state of microbial degradation and adjusts the supply of reformed material based on detected variations in feed properties. This allows the system to maintain high microbial degradation efficiency while processing diverse and heterogeneous waste materials
Solution Approach 2:
The system adjusts supply parameters (amount and timing) in response to heterogeneous feed properties, maintaining optimal microbial degradation conditions despite variations in feed composition and characteristics
