Biological Prototype Acquisition Based on Biological Coupling in Bionic Design

Table 7

The comparison of the scheme before and after improvement.

Structure	Prebionic improvement	After bionic improvement
Upper skewer structure	The regular shape of the upper skewer shaft easily causes the gear skewer to jam and affects the use effect	The groove design that fits the shape of the gear skewer greatly avoids the problem of clamping the skewer
Skewer-pushing structure	The sensitivity of skewer recognition is low, which easily causes the problem of empty skewer threading or nonretraction after threading	The bionic snail eyes design increases the receptors and enhances the sensitivity of the skewer-pushing structure
Walking plate structure	The large-scale die structure is difficult to adapt to all types of threading machines	The bionic Gaboon viper design increases the flexibility of the die plate
Packaging structure	The manual packaging method reduces the efficiency of the whole process	The integration of the packaging structure into the whole machine improves the operation efficiency
