Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If general-purpose liquid organosilicon compounds are used, then they can be easily handled as liquids, but they cannot be used without liquid handling equipment and cause solid materials to become sticky
Solution Approach 1:
The patent changes the physical state parameter of the organosilicon compound from liquid to solid by incorporating it into a polymer matrix through spray drying, eliminating the need for specialized liquid handling equipment and preventing stickiness issues
Solution Approach 2:
The patent creates a composite material system consisting of organosilicon compound particles dispersed in a polymer matrix, combining the benefits of solid handling with the functional properties of organosilicon compounds
2Shape
If spray drying is used to solidify organosilicon compounds, then solid materials are obtained, but the organosilicon compound undergoes hydrolysis and condensation during the process
Solution Approach 1:
The patent performs preliminary protection of the organosilicon compound by embedding it in a polymer matrix before the spray drying process, preventing hydrolysis and condensation from occurring during solidification
Solution Approach 2:
The polymer matrix acts as an intermediary protective layer around the organosilicon compound particles, isolating them from moisture and preventing unwanted chemical reactions during the spray drying process
3Shape
If wax impregnation is used to achieve solidification, then solid organosilicon compound composition is obtained, but the organosilicon compound content is diluted and the wax component may adversely impact other compositions
Solution Approach 1:
The patent extracts and eliminates the wax component from the solidification process, using only the minimal necessary polymer matrix material to achieve solidification while maintaining high organosilicon compound content
Solution Approach 2:
The patent optimizes the polymer matrix content to the minimum required level for solidification, maximizing the organosilicon compound concentration while still achieving the desired solid physical state
