Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If ascorbic acid 2-glucoside is used instead of ascorbic acid, then stability is improved, but browning reaction still occurs
Solution Approach 1:
The patent uses ascorbic acid 2-glucoside as an intermediary compound that converts to ascorbic acid in the body, providing the desired antioxidant effects while avoiding the direct instability and browning issues of pure ascorbic acid. This intermediary approach resolves the contradiction by delivering benefits indirectly through metabolic conversion.
Solution Approach 2:
The patent creates a composite system by combining ascorbic acid 2-glucoside with other stabilizing components and delivery systems, forming a composite material that enhances overall stability while preventing browning reactions. This composite approach allows the beneficial properties to be maintained while mitigating the harmful browning effect.
2Reliability
If ascorbic acid is used in high concentration, then effectiveness is improved, but skin irritation increases
Solution Approach 1:
Ascorbic acid 2-glucoside serves as a gentler intermediary that converts to active ascorbic acid in the skin, providing high concentration effectiveness without the direct irritation caused by pure ascorbic acid. The glucoside form is less irritating while maintaining the ability to deliver high levels of active vitamin C through metabolic conversion.
Solution Approach 2:
The patent changes the chemical parameter of ascorbic acid by converting it to its 2-glucoside derivative form. This parameter change modifies the properties to reduce skin irritation while preserving the ability to provide high concentration effectiveness through in vivo conversion to the active form.
3Ease of operation
If ascorbic acid is used in aqueous solution, then usability is improved, but oxidation occurs rapidly
Solution Approach 1:
The patent uses ascorbic acid 2-glucoside as a stable intermediary that can be formulated in aqueous solutions without rapid oxidation. This intermediary form maintains stability in aqueous environments while still providing the ability to convert to active ascorbic acid when needed, resolving the contradiction between aqueous usability and oxidation resistance.
Solution Approach 2:
The patent performs preliminary conversion of ascorbic acid to its 2-glucoside form before formulation, which preemptively prevents oxidation issues in aqueous solutions. This preliminary action stabilizes the compound for aqueous formulation while preserving the ability to deliver active ascorbic acid through subsequent metabolic conversion.
