Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional cooking method or ethanol extraction method is used to produce egg yolk oil, then the yield is fairly good, but the product has strong egg odor and obvious yellow color, limiting industrial applicability
Solution Approach 1:
The patent extracts and removes the harmful components (odor and color) from the egg yolk oil through systematic decolorization and deodorization processes. This involves separating the undesirable properties from the valuable oil product, achieving both good yield and acceptable product quality.
Solution Approach 2:
The patent employs multiple parameter changes including pH adjustment, temperature control during processing, and solvent selection to optimize both yield and product quality. By controlling these parameters systematically, the method achieves high yield while minimizing harmful characteristics.
2Quantity of substance
If traditional cooking method is used, then yield can reach 10-15%, but the process depends on experience and skills, making it difficult to control and不适合 large-scale production
Solution Approach 1:
The patent replaces the experience-based manual cooking process with a systematic chemical processing method involving controlled extraction, filtration, and purification steps. This substitution of manual skill-based operations with standardized procedural steps enables consistent results and facilitates large-scale production.
Solution Approach 2:
The method establishes specific parameter ranges for pH, temperature, and processing time that replace the need for operator experience. By defining these parameters scientifically, the process becomes controllable and reproducible in industrial settings while maintaining high yield.
3Object-generated harmful factors
If decolorization and deodorization processes are applied, then product quality is improved, but additional processing steps are required
Solution Approach 1:
The patent combines multiple decolorization and deodorization operations into an integrated processing sequence. By merging these functions into a coordinated series of steps using compatible reagents and conditions, the method achieves effective purification without requiring excessively complex or separate equipment for each function.
