Engineering Contradiction Analysis
1Object-generated harmful factors
If biodegradable polymers like polylactide are used to replace synthetic polymers, then biodegradability is improved, but mechanical strength deteriorates
Solution Approach 1:
The patent uses a composite material system consisting of biodegradable polymer particles (97-99.9 wt%) combined with an epoxide compound (0.1-3 wt%). This composite approach allows the biodegradable polymer to provide environmental benefits while the epoxide compound acts as a reinforcing agent that significantly enhances mechanical strength, thereby resolving the contradiction between biodegradability and mechanical strength
Solution Approach 2:
The patent changes the chemical and physical parameters of the biodegradable polymer by introducing small amounts of epoxide compound. This parameter change (adding 0.1-3 wt% epoxide) transforms the polymer's mechanical properties, increasing strength and stiffness while maintaining the bulk biodegradability characteristic, thus resolving the strength deficiency of conventional biodegradable fabrics
2Area of stationary object
If fiber diameter is reduced to enhance fabric properties, then surface area and reactivity are improved, but mechanical strength deteriorates
Solution Approach 1:
The patent applies composite materials by incorporating epoxide compound particles into the biodegradable polymer matrix. This composite structure provides reinforcement at the micro level, allowing ultrafine fibers to maintain high tensile strength despite their small diameter, thereby enabling both high surface area and mechanical integrity
