Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic phenolic antioxidants are used for stabilization, then long-term heat stability is improved, but toxicity and environmental contamination increase
Solution Approach 1:
The patent changes the chemical composition parameter by replacing synthetic phenolic antioxidants with cholestanyl ferulate, a natural sterol ester derivative. This substitution maintains the stabilizing function while eliminating toxicity and environmental contamination issues associated with synthetic compounds.
Solution Approach 2:
The patent employs a natural, biodegradable antioxidant (cholestanyl ferulate) that can be safely replaced or degraded in the environment, contrasting with persistent synthetic antioxidants. This approach prioritizes environmental safety and health considerations over long-lasting synthetic stabilization.
2Object-affected harmful factors
If natural antioxidants like Vitamin E are used, then toxicity is reduced, but radical scavenging ability and heat stability are insufficient
Solution Approach 1:
The patent creates a composite antioxidant system by combining cholestanyl ferulate with other natural antioxidants such as tocopherols and ascorbyl palmitate. This composite approach synergistically enhances radical scavenging ability and heat stability while maintaining the low toxicity profile of natural compounds.
Solution Approach 2:
The patent modifies the molecular structure and composition of natural antioxidants by using cholestanyl ferulate, a sterol ester derivative, which provides superior radical scavenging activity compared to conventional Vitamin E while maintaining natural safety profiles.
3Object-affected harmful factors
If conventional biobased antioxidants are used, then environmental safety is improved, but discoloration and organoleptic issues worsen
Solution Approach 1:
The patent changes the chemical structure to cholestanyl ferulate, which has superior stability properties that prevent discoloration and maintain organoleptic properties during processing and service life, while preserving environmental safety and biodegradability.
