Drill Bits TRIZ Cases
- Directional Drill Head With Angled Liquid Ports
Angled liquid ports wash away compacted soil to create steering pockets, resolving forward progress and directional control contradictions.
- Compound Extruded Expanded Pile Forming Equipment
Integrated drilling tool extrudes variable section bore to improve bearing capacity without pre-forming complex procedures.
- Rotary Drag Bit Composite Cutting Structure Erosion Resistance
A rotary drag bit uses abutting prefabricated cutters to form a continuous composite cutting structure that presents a seamless profile.
- Drill Bit Nozzle With Secondary Passages for Erosion Control
Diverging secondary passages in a drill bit nozzle direct fluid to high-wear zones, reducing erosion while maintaining cooling and cleaning functions.
- Bidirectional Stabilizer for Wellbore Smoothing and Drilling Fluid Flow
A bidirectional stabilizer with cutting blades and nodes smooths wellbores while rotating in both directions.
- Rotational Hold Down System for Drilling Torque Isolation
A rotational hold down system constrains drill string rotation to direct torque to the bit.
- Excavation Tool Locking Pin Retention Mechanism
Rigid fixing member and locking portion prevent locking pin displacement under excavation impact forces.
- PDC Reamer Blades with Staggered Cutter Patterns
Segmented PDC reamer blades use staggered cutter patterns to balance force distribution and wear across cutting surfaces.
- Adjustable Diameter Underreamer Cutter Block Dynamics
A pin and annular sleeve mechanism moves the cutter block axially to adjust its diameter, eliminating tool withdrawal delays caused by vibration wear.
