Electrospinning Sideway Motion for Aligned Microtube Arrays

The patent applies dynamics by introducing a rotating collector that moves dynamically during the electrospinning process. The collector rotates at controlled speeds (e.g., 100-1000 RPM) to actively align fibers in the deposition direction while maintaining continuous fiber production. This dynamic motion transforms the static collection process into an active alignment mechanism, simultaneously achieving high fiber alignment quality and sustained production speed.

The patent applies segmentation by replacing the single needle spinneret with a multi-nozzle array configuration. The spinneret contains multiple nozzles arranged in specific patterns (e.g., 5-20 nozzles per spinneret, with 1-5 spinnerets total) to simultaneously produce multiple fiber bundles. This segmentation dramatically increases production capacity while keeping each individual nozzle simple in structure, effectively scaling up output without proportionally increasing complexity.

The patent applies universality by designing a collector system that performs multiple functions simultaneously: it collects fibers, aligns them through rotation, and can be configured in various arrangements (rotating disc, rotating drum, or stationary plate with controlled motion). This multi-functional collector design achieves high fiber alignment without requiring overly complex structures, as the same rotating mechanism serves both collection and alignment purposes.
