AI Technical Summary

Technical Problem

Existing chewing simulation technologies struggle to replicate the complex three-dimensional movements of teeth and the transfer of food between different tooth regions in a real oral cavity, and are prone to causing food to get stuck due to hard food.

Method used

A rotating component drives multiple sets of arc-shaped chewing plates to perform circumferential sweeping motion. Combined with a spacing adjustment mechanism and a pump-pump tumbling mechanism, it simulates the three-dimensional chewing trajectory of teeth. Spring support rods buffer the resistance of hard objects, and the pump-pump tumbling mechanism simulates the stirring function of the tongue.

Benefits of technology

It significantly improves the realism of chewing motion simulation, prevents food from getting stuck, ensures that food is loose and can be effectively chewed, and promotes the even mixing of food and saliva.
