Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent changes the physical and chemical parameters of collagen through controlled denaturation at specific temperatures (215-280°C) and pH levels, transforming native collagen into denatured collagen that can be stably blended with polyamide fibers. This parameter change resolves the contradiction by making collagen compatible with synthetic fibers while maintaining its moisture-absorbing properties.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite material system where denatured collagen and polyamide fibers are blended in specific ratios (0.1-3 parts collagen per 97-99.9 parts polyamide). This composite approach allows the hydrophobic polyamide to provide manufacturing stability while the collagen provides moisture regain, resolving the contradiction between comfort improvement and manufacturing reliability.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If collagen is blended with synthetic fibers to create textile products, then product functionality is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveproduct functionalityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent performs preliminary denaturation of collagen before blending with synthetic fibers. By pre-processing the collagen to its denatured state with appropriate molecular weight (900-11,000 Da), the manufacturing process is simplified because the denatured collagen is more compatible and easier to blend uniformly with polyamide fibers, reducing overall manufacturing complexity despite enhanced product functionality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies local quality by using specific ranges of collagen molecular weights (900-11,000 Da) and controlling the blending ratio (0.1-3 parts collagen). This localized optimization of collagen properties ensures that only the appropriate fractions of collagen are used, making the manufacturing process more manageable while achieving the desired functional benefits in the final textile product.

Inventive Principle:
Principle #3Local quality

3Reliability

If native collagen is used in blend composition, then biological properties are maintained, but compatibility with synthetic fibers deteriorates

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies parameter changes by denaturing collagen through controlled heating (215-280°C) and pH adjustment, which alters the physical and chemical properties of collagen to improve compatibility with synthetic fibers. This transformation maintains the essential biological properties and amino acid composition while changing the structural parameters to enable successful blending with polyamide fibers.
