Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If acrylic fibers are used for artificial fur, then lightness and warmness are achieved, but moisture-absorbing property deteriorates and environmental impact increases
Solution Approach 1:
The patent changes the material parameter from acrylic fiber to protein fiber, fundamentally altering the chemical composition to improve moisture absorption while maintaining warmth. Protein fibers have inherent hygroscopic properties that acrylic fibers lack, directly resolving the contradiction between warmth and moisture absorption.
Solution Approach 2:
The patent uses composite structures including protein fibers with crosslinking agents and hydroxyl group-containing polymers to create an artificial fur that combines the warmth of synthetic materials with the moisture-absorbing properties of natural protein fibers, achieving both thermal comfort and hygroscopic functionality.
2Productivity
If acrylic fibers are used for artificial fur, then mass production is enabled, but sensitivity to moisture and water increases causing dimensional changes
Solution Approach 1:
The patent changes the fiber material from acrylic to protein-based fibers, which have different physical and chemical properties. Protein fibers exhibit superior dimensional stability when exposed to moisture compared to acrylic fibers, while still allowing for mass production through standardized manufacturing processes.
Solution Approach 2:
The patent applies crosslinking agents and hydroxyl group-containing polymers specifically to the protein fiber structure to enhance dimensional stability in regions prone to moisture exposure, while maintaining the overall mass production capability through controlled application of these treatments during the manufacturing process.
3Reliability
If protein fibers are used for artificial fur, then moisture-absorbing property is improved, but shrinkage on contact with water occurs
Solution Approach 1:
The patent applies crosslinking agents and hydroxyl group-containing polymers to the protein fibers before final product formation. This preliminary treatment creates a protective crosslinked structure that prevents water-induced shrinkage while preserving the fibers' natural moisture-absorbing capability, effectively pre-conditioning the material to avoid later dimensional instability.
Solution Approach 2:
The patent introduces crosslinking agents and hydroxyl group-containing polymers as intermediary substances that mediate between the protein fiber and water. These intermediaries form a protective network around the protein fibers, allowing moisture absorption while preventing the fiber structure from shrinking when exposed to water.
4Reliability
If modified fibroin fiber is used for artificial fur, then moisture-absorbing and heat-releasing properties are enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent modifies the fibroin fiber through controlled chemical treatments with crosslinking agents and hydroxyl group-containing polymers. These parameter changes enhance moisture absorption and heat release properties while the manufacturing complexity is managed through standardized treatment protocols and sequential processing steps that can be integrated into existing production lines.
