The keywords focus on the carrier and the production method of the head assembly. This indicates a focus on overcoming manufacturing complexity or mechanical failure at the attachment interface.

The keywords indicate bottlenecks in the automated transport and positioning of bristles during high-speed brush manufacturing. Solving this prevents production downtime and ensures consistent tuft density.

Mechanical instability or loosening at the interface between the handle and the replaceable head. Ensuring a secure connection prevents vibration loss and accidental detachment during use.
