Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If azulene sodium sulphonate is used as the active ingredient, then excellent anti-inflammatory and wound healing properties are achieved, but poor light stability and heat stability cause decomposition and impurity generation
Solution Approach 1:
The patent modifies the chemical structure of azulene sodium sulphonate by introducing N-substituted isopropyldimethyl azulene sulfonamide derivatives, changing the molecular parameters to improve stability while maintaining therapeutic activity
Solution Approach 2:
The patent creates composite molecular structures by combining azulene core with sulfonamide groups and various substituent groups (R1-R6), forming stable conjugated structures that resist decomposition
2Reliability
If special storage conditions are implemented to prevent decomposition, then product safety is improved, but storage and transportation costs increase
Solution Approach 1:
The patent converts the harmful decomposition tendency of azulene sodium sulphonate into a benefit by structurally modifying it to create stable derivatives that naturally resist decomposition, eliminating the need for special storage conditions
3Reliability
If structural modification is performed to improve stability, then decomposition is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent segments the molecular structure into distinct functional groups (azulene core, sulfonamide group, and substituent groups R1-R6), allowing independent optimization of each part while maintaining overall stability
Solution Approach 2:
The patent introduces different substituent groups at specific positions of the azulene molecule to locally improve stability at critical sites while maintaining the overall therapeutic activity of the compound
