Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an electrostatic nanofilm layer is applied to metal wire mesh screens, then particulate matter filtration and water repellency are improved, but durability under wind and sunlight exposure deteriorates and production cost increases
Solution Approach 1:
The patent uses composite yarns combining polyester and polypropylene filaments with different denier values to create a mesh fabric that integrates filtration, water repellency, and durability functions into the base material structure, eliminating the need for separate electrostatic nanofilm coatings that deteriorate under environmental exposure
2Object-affected harmful factors
If sodium polyacrylate coating is applied to screen yarns, then water resistance and ventilation are improved, but heat resistance and sun exposure resistance deteriorate
Solution Approach 1:
The patent changes the material parameters by using inherently water-repellent polyester and polypropylene polymers with appropriate hydrophobic properties, replacing the sodium polyacrylate coating that expands and contracts with moisture. This material substitution maintains water resistance while providing stability under heat and sunlight exposure
3Object-affected harmful factors
If shuttle (plain) weave structure is used, then particulate matter blocking and air circulation are improved, but yarn slippage and fabric stability deteriorate
Solution Approach 1:
The patent segments the yarn structure into monofilaments and multifilaments with different denier values arranged in specific patterns, creating a more stable three-dimensional mesh structure that resists yarn slippage while maintaining particulate matter blocking capability and air circulation
4Object-affected harmful factors
If water-repellent coating is applied to shuttle weave fabric, then rainwater repulsion and air circulation are improved, but fabric elasticity and flexibility deteriorate
Solution Approach 1:
The patent uses composite yarns with varying filament denier values and material compositions that provide inherent water repellency while maintaining fabric elasticity and flexibility, enabling the mesh to be used in retractable screens and other applications requiring movement

AI summary
The present invention provides a fiber with a multi-filament structure and a textile fabric, curtain, and screen incorporating such fiber. The multi-filament fiber includes multiple filaments and a blended material. Each filament is a columnar body arranged adjacently or in a spiral adjacent arrangement to form a yarn having an appropriate length. The blended material contains a nano-fluorine water-repellent material and a bonding material provided in gaps between the filaments. Multiple fibers are arranged at intervals horizontally or vertically and knitted in the weft or warp direction to form a meshed textile fabric. The fabric is further coated with an adhesive and a nano-fluorine water-repellent material for use in screens, thereby achieving water repellency and air pollution prevention. Meanwhile, the meshed textile fabric exhibits improved stiffness, elasticity, and transparency, making it suitable for retractable screen fabrics.
