Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fibers with different outer diameters are combined to create a bulky fiber article, then the functionality and performance of the fiber article are improved, but the production efficiency decreases and it becomes difficult to produce efficiently
Solution Approach 1:
Resin particles are applied to the fiber surface in advance before the actual fiber formation process. This preliminary action allows the fine fibers to form directly from these pre-positioned particles during subsequent processing, eliminating the need for separate fine fiber production steps and enabling efficient production of multi-functional fiber articles
Solution Approach 2:
The production method combines multiple functions into a single fiber article by integrating coarse support fibers and fine functional fibers in one manufacturing process. Different types of fibers with different outer diameters are combined in one article, achieving both structural support and fine functional properties simultaneously, which improves production efficiency while maintaining high functionality
2Reliability
If fibers with extremely small outer diameters are used to achieve fine functionality, then the functional performance is improved, but the production difficulty increases significantly
Solution Approach 1:
Resin particles serve as an intermediary medium in the production process. Instead of directly producing extremely fine fibers which is difficult, the method uses resin particles as intermediaries that are first applied to fiber surfaces, then transformed into fine fibers through subsequent processing. This intermediary approach simplifies the manufacturing of ultra-fine fibers while maintaining their functional properties
Solution Approach 2:
The method changes the production parameters by forming fine fibers from resin particles rather than spinning them directly. By controlling the transformation of resin particles into fine fibers through external force application and subsequent relief, the process achieves production of extremely fine fibers (30 nm to 1.0 μm) that would be difficult to manufacture using conventional spinning methods
3Manufacturing precision
If separate steps are used to form fine fibers and combine them with other fibers, then the uniformity and quality are improved, but the production complexity and costs increase
Solution Approach 1:
The production method merges the fine fiber formation step with the fiber combination step into a single integrated process. By forming fine fibers directly from resin particles that are already positioned on fiber surfaces, and simultaneously combining them with support fibers in one process, the method achieves uniform distribution without requiring separate production lines or complex multi-step procedures
Solution Approach 2:
The resin particles self-organize and transform into fine fibers at their designated positions on the fiber surface. When external force is applied and then relieved, the resin particles automatically form fine fibers in situ, eliminating the need for separate fiber formation equipment and complex handling processes. This self-service mechanism ensures uniform distribution while simplifying the production system
