Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 1,2-alkane polyol is used in cosmetics, ink, fibers, or coatings, then functional performance is improved, but chemical stability deteriorates leading to deterioration over time
Solution Approach 1:
A carboxylic acid derivative is introduced as an intermediary substance that reacts with the 1,2-alkane polyol to form a stable complex. This mediator prevents direct oxidation of the polyol while maintaining its functional properties in cosmetics, ink, fibers, and coatings applications.
Solution Approach 2:
The invention creates a composite system combining 1,2-alkane polyol with carboxylic acid derivative and optionally thiazoline derivative. This composite material exhibits both the functional benefits of the polyol and the stability provided by the acid derivative complex, resolving the contradiction between performance and stability.
2Stability of the object's composition
If 1,2-alkane polyol is stabilized by adding carboxylic acid derivative, then chemical stability is improved, but product complexity increases
Solution Approach 1:
The invention optimizes the molecular structure parameters of the carboxylic acid derivative, selecting specific chain lengths and functional groups that provide effective stabilization with minimal impact on the overall composition. This parameter optimization reduces complexity while maintaining stability benefits.
3Duration of action of stationary object
If 1,2-alkane polyol deteriorates over time, then decomposition products are generated, but harmful effects such as coloring, smell, and stimulation increase
Solution Approach 1:
The carboxylic acid derivative is added in advance to prevent decomposition of the 1,2-alkane polyol before it can generate harmful products. This preliminary protective action blocks the decomposition pathway, extending shelf life while preventing the formation of coloring agents, odorous compounds, and刺激性 substances.
