·Optimization of PDC and roller cutting profiles to enhance the foller function of torque reduction, improving the controllability of the drill bit's sliding guide surface.

·Analysis of cutting structure force balance design to improve the stability of the drill bit, reduce the stick-slip effect, and enhance the directional performance of the drill bit.

·Combination of shorter gauge design and active/passive gauge retention to improve the build-uprate, lateral cutting performance, and directional controllability of the drill bit.

·Design of multi-point gauge and gauge retention balancing positioning and stabilization structure to improve the stability of the drill bit and its adaptability in directional drilling.
