Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plant extracts are used to modify nylon fibers for antioxidant functionality, then antioxidant performance is improved, but binding performance between antioxidant active components and nylon fibers deteriorates
Solution Approach 1:
The patent introduces a carrier as an intermediary substance to bridge the plant extract and nylon fiber. The carrier absorbs the plant extract first, then the loaded carrier is combined with nylon fiber through masterbatch preparation. This intermediary approach solves the poor direct binding between plant extracts and nylon fibers while maintaining antioxidant performance.
2Manufacturing precision
If acidic dyeing process is used to achieve ideal dyeing effect, then dyeing uniformity is improved, but stability of antioxidant active components deteriorates
Solution Approach 1:
The patent performs preliminary action by pre-loading the plant extract onto the carrier before the dyeing process. The carrier is prepared in advance to protect the active components, ensuring they remain stable during subsequent acidic dyeing operations while still allowing uniform dyeing to occur.
3Reliability
If plant extracts are added to modify nylon fibers, then antioxidant functionality is improved, but physical properties of nylon fibers deteriorate
Solution Approach 1:
The patent segments the antioxidant functional modification into separate components: the plant extract loaded onto a carrier, and the nylon fiber base material. This segmentation allows the antioxidant functionality to be added without directly compromising the physical properties of the nylon fiber, as the plant extract is contained within the carrier structure.
4Ease of operation
If repeated washing is performed on modified nylon fibers, then cleanliness is improved, but wash resistance of antioxidant active components deteriorates
Solution Approach 1:
The patent creates a composite material structure where the plant extract is combined with a carrier material that provides binding affinity to nylon fiber. This composite approach ensures the antioxidant active components remain attached to the fiber even after repeated washing, maintaining wash resistance while allowing normal cleaning.
