Introduction

James Jing Yao is a notable inventor based in Mississauga, Canada. He has made significant contributions to the field of drilling technology, holding two patents that showcase his innovative approach to solving industry challenges.

Latest Patents

One of his latest patents is the "Threaded Coupling for Percussion Drill Bit." This invention features an internally threaded bit designed for percussion drilling, which has thread roots that are wider than the thread crests. This design allows a single drill bit to connect to various rods with differing crest widths in their male threads. The invention optimizes the service life of the rods according to specific drilling conditions, eliminating the need for a large inventory of drill bits. Additionally, the bit exhibits a reduced rate of ringing off and can accommodate drill rods with a range of crest widths.

Another significant patent is the "Straight Hole Drilling System." This innovation involves a drill rod for a drill string that has threads at each end and connects to an adjacent rod via a sleeve. The configuration of the threads on the sleeve and rod is designed to minimize stress concentrations and provide sacrificial wear on the sleeve. The thread features a single start with a part circular root, ensuring that the wear volume on the sleeve is less than that on the rod. The outer diameter of the rod is at least twice that of the inner bore, enhancing its durability.
