Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If abrasives are recycled after use, then abrasive consumption cost is reduced, but cutting power decreases due to size reduction and shape changes

Engineering Contradiction:

Core Design Contradiction:
Loss of substanceVSPower

Solution Approach 1:

The system changes operating parameters (fluid pressure, cutting speed, abrasive flow rate) to compensate for the reduced cutting power of recycled abrasives. By adjusting these parameters dynamically, the system maintains effective cutting performance while utilizing recycled abrasives that have undergone size reduction and shape changes.

Inventive Principle:

Solution Approach 2:

The system dynamically adjusts operating parameters based on the condition of recycled abrasives. Rather than using static parameters, the system adapts fluid pressure, cutting speed, and abrasive flow rate in real-time to compensate for abrasive degradation, thereby maintaining cutting power while recycling abrasives.

Inventive Principle:

AI summary

Disclosed herein are components, systems, and methods of operating an abrasive fluid jet system that recycles and reuses abrasive particles for multiple cycles. The systems and methods include adjusting one or more operating parameters of the abrasive fluid jet system to compensate for a reduction in cutting power of the used abrasives as the used abrasive particles are continuously discharged from the outlet of the cutting head across multiple cycles. The one or more operating parameters include fluid pressure that forms the fluid jet, a cutting speed of the cutting head, and flow rate of abrasive particles, which are changeable while continuing to operate the abrasive fluid jet system. The one or more operating parameters include an orifice size through which a fluid passes to generate the second fluid jet, a mixing tube diameter through which the second abrasive fluid jet passes, and a length of the mixing tube.
