Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If electrospinning is used to produce nanofibers, then nanofibers can be manufactured, but control over chemical and physical properties and uniform fiber distribution is difficult to achieve
Solution Approach 1:
The patent replaces the electrospinning mechanical system with a centrifugal spinning system. Instead of using high voltage electric fields to draw fibers, the invention uses a rotating drum with centrifugal force to extrude material through openings, achieving fiber production with better control over diameter and distribution while simplifying the overall process control mechanism
Solution Approach 2:
The invention changes the controlling parameters from electrical field strength in electrospinning to rotational speed, material viscosity, and opening geometry in centrifugal spinning. By adjusting rotation speed and material properties rather than complex electrical parameters, the system achieves precise control over fiber diameter and uniform distribution
2Productivity
If centrifugal force is applied to produce fibers, then fiber production efficiency improves, but control over fiber properties becomes more challenging
Solution Approach 1:
The patent applies local quality by designing different opening geometries, sizes, and distributions at specific locations on the rotating drum to control local fiber properties. The material composition and viscosity can also be varied locally to achieve specific fiber characteristics in different regions, maintaining precision control while enabling high-volume production
Solution Approach 2:
The invention uses dynamic control of rotation speed during the spinning process to adjust fiber properties in real-time. By varying rotational velocity, the system can control centrifugal force magnitude, thereby adjusting fiber diameter, length, and distribution dynamically while maintaining high productivity
3Manufacturing precision
If uniform fiber distribution is achieved, then application quality improves, but production complexity increases
Solution Approach 1:
The patent segments the fiber production process into controlled extrusion through discrete openings on the rotating drum, followed by centrifugal distribution. The openings are strategically positioned and sized to ensure uniform material discharge, and the rotation naturally distributes fibers evenly across the collection surface, achieving uniform distribution through simple geometric design rather than complex control systems
