Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If coarse additives are used in drilling fluid, then fluid circulation efficacy is improved, but equipment wear increases
Solution Approach 1:
The patent changes the physical parameter of additive particle size by introducing a shearing device that reduces particle diameter from coarse to fine dimensions. This transformation allows the fluid to maintain circulation efficacy while the reduced particle size minimizes wear on drilling equipment, directly resolving the contradiction between productivity and equipment protection.
2Object-affected harmful factors
If additives are made finer, then equipment wear is reduced, but fluid circulation efficacy decreases
Solution Approach 1:
The shearing device optimizes the particle size parameter to a specific fine range that maintains fluid rheological properties necessary for circulation while being sufficiently fine to reduce equipment wear. This precise parameter control resolves the contradiction by finding the optimal point where circulation efficacy is preserved and wear is minimized.

Function Achieved in This Case
Effectively reduces additive coarseness to enhance drilling efficiency by minimizing equipment wear and improving fluid circulation efficacy.
Implementation Method 1
A drill string is used to create a borehole... A drilling fluid or drilling mud is circulated through the drill string... The coarser the additive, the more they can wear on the drilling equipment... there is a need for a system and method for shearing the additives in the drilling fluid
Implementation Method 2
a disk shears the fluid as the fluid moves across a surface of the disk

AI summary
A system and method for shearing a fluid. The system includes a turbine having a rotational axis, a fluid inlet for receiving the fluid, a disk rotatable about the rotational axis at a selected speed, and a fluid outlet for expelling the fluid from the turbine. The fluid flows across a surface of the disk, and the disk shears the fluid as the fluid moves across a surface of the disk.
