Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cooking oil is reused multiple times in conventional fryers, then cost is reduced, but food taste deteriorates and harmful substances are generated
Solution Approach 1:
The system performs preliminary filtration of cooking oil before it accumulates harmful substances and loses taste. The filtration device continuously removes food residues and carbonization particles from the oil, preventing the degradation that would otherwise occur after multiple reuse cycles. This proactive maintenance of oil quality enables extended reuse without compromising food taste or generating harmful substances.
Solution Approach 2:
The fryer system automatically filters and maintains its own cooking oil without external intervention. The control unit activates the filtration device at predetermined intervals or when specific conditions are met, allowing the system to self-maintain oil quality. This automated self-service capability ensures continuous oil purification, enabling extended reuse while preventing taste deterioration and harmful substance formation.
2Object-affected harmful factors
If cooking oil is discarded after limited use, then food quality is maintained, but resource waste and environmental pollution increase
Solution Approach 1:
Instead of discarding used cooking oil after limited use, the system recovers and purifies it through automatic filtration. The filtration device continuously removes contaminants and carbonization particles, restoring the oil to a reusable state. This recovery process extends the oil's service life significantly, reducing waste and environmental pollution while maintaining food quality standards.
Solution Approach 2:
The system maintains continuous filtration of cooking oil throughout its use period, ensuring the oil remains clean and effective for frying. Rather than allowing the oil to degrade and then discarding it, the continuous purification action keeps the oil in optimal condition, enabling extended reuse without compromising food quality. This continuous useful action transforms the oil from a single-use resource into a reusable asset.
3Object-affected harmful factors
If manual oil filtering is performed, then oil quality is improved, but time consumption and labor increase
Solution Approach 1:
The fryer system automatically performs oil filtration without requiring manual intervention. The control unit monitors oil usage and automatically activates the filtration device at predetermined intervals or when specific conditions are met. This automated self-service capability eliminates the time-consuming manual filtering process while maintaining high oil quality standards, allowing users to simply add water and salt without needing to manually strain or filter the oil.
Solution Approach 2:
The system replaces manual mechanical filtration with an automated filtration mechanism controlled by a control unit. Instead of requiring users to manually strain oil through filters, the system uses an automated filtration device that circulates and purifies the oil automatically. This substitution of manual mechanical action with an automated control system dramatically reduces time consumption while maintaining or improving oil quality.
4Object-affected harmful factors
If frequent oil replacement is performed, then food taste and safety are maintained, but operating cost increases
Solution Approach 1:
The system performs preliminary and continuous filtration to prevent oil degradation before it affects food taste or safety. By continuously removing food residues and carbonization particles, the oil maintains high quality standards for much longer periods. This prevents the need for frequent oil replacement, reducing cooking oil consumption while maintaining food taste and safety.
Solution Approach 2:
Instead of discarding oil after it reaches the end of its useful life, the system continuously recovers and purifies it through automatic filtration. This recovery process extends the oil's service life from typically a few uses to many more uses, significantly reducing the total quantity of cooking oil needed while maintaining food taste and safety through continuous purification.
