Functional requirements include high-speed operation, compact size, and flexibility for both knot types. Dimensional synthesis methods utilize precision point and approximate synthesis techniques for mechanism design. Future work involves developing auxiliary mechanisms for yarn preparation and control in the knotting system.

Currently, the knotting of chemical fiber filament packages in factories primarily comprises manual operations. It also has a high labor intensity and is subject to artificial subjective factors ...

Little is known regarding the effects of knotting on the mechanical properties of individual molecules. Here, we report on the force response of discrete synthetic small-molecule trefoil knots upon tightening. By combining single-molecule force spectroscopy with quantum chemical calculations, we provide evidence for the mechanism of tightening. It is associated with a higher resisting force ...

For example, mature viruses only exhibit 47% knotting relative to mutants which exhibit 95% knotting [2], suggesting that there is some internal packing mechanism to reduce the rate of knot formation as a purely equilibrium system should trend toward 100% knotting as observed in the mutant.

Useful Notes on Knotting Precision As A Deterrent Mechanism

The knot-tripping mechanism in the knotter is designed as a line-contact curved-surface cam mechanism , with the cutter arm swinging in accordance with sinusoidal acceleration. The design significantly reduces the contact stress between the cam and the roller, compared to the original knot-tripping mechanism .
