Cutting Jet Interruption via Interfering Medium
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for interrupting a cutting jet, such as those used for cutting materials, rely on switching valves that are subjected to extreme stress due to high pressure, leading to reduced valve life and increased costs, especially when producing complex patterns.
Innovation Solution
The method eliminates the need for switching valves by maintaining high-pressure fluid supply and using an interfering medium, such as water or air, or a solid pin, to reduce the cutting jet's speed and energy, allowing for continuous cutting head movement without material abrasion, with the introduction of an interfering means controlled by a quick closing valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If switching valves are used to interrupt the cutting jet, then the cutting jet can be stopped to insert patterns, but the valves are subject to extreme stress from high pressure which reduces their life and increases costs
Solution Approach 1:
The patent introduces an interfering medium (liquid or gaseous) as an intermediary substance that is injected into the cutting jet to reduce its speed and energy, thereby stopping the cutting action without requiring switching valves. This intermediary medium acts as a mediator between the high-pressure fluid supply and the cutting head, allowing pattern insertion while eliminating valve stress.
Solution Approach 2:
The patent replaces the mechanical switching valve system with a fluid dynamic approach using an interfering medium. Instead of mechanically opening and closing valves to stop the cutting jet, the system uses a controlled injection of interfering medium that reduces the kinetic energy of the cutting jet, achieving the same functional result without mechanical stress on valves.
2Adaptability or versatility
If switching valves are used to interrupt the cutting jet, then pattern insertion is enabled, but downtime to change valves increases production costs
Solution Approach 1:
The patent enables continuous operation by maintaining the high-pressure fluid supply continuously while using the interfering medium to temporarily reduce cutting action for pattern insertion. This eliminates the need to stop the entire system or replace valves, allowing continuous cutting and pattern insertion operations without downtime.
Solution Approach 2:
The interfering medium serves as a temporary mediator that allows pattern insertion during continuous operation. By injecting the interfering medium into the cutting jet, the system can create patterns without stopping the main cutting process or requiring valve replacement, thereby maintaining productivity.
3Stability of the object's composition
If a plunger pump with overflow system is used to generate pressure, then consistent pressure is achieved, but extremely high stress results which prevents satisfactory operation
Solution Approach 1:
The interfering medium acts as an intermediary that reduces the stress on the system by absorbing excess energy. When the interfering medium is injected into the cutting jet, it creates a region of reduced pressure and velocity, thereby reducing the overall stress on the plunger pump and overflow system while maintaining consistent pressure generation.

Function Achieved in This Case
This approach reduces wear on equipment, minimizes production and operating costs, and enables the creation of intricate patterns without valve stress, ensuring efficient and economical operation.
Implementation Method 1
the cutting jet is supplied with interfering means following the exit of the nozzle that reduces the speed and energy density of the cutting jet
Implementation Method 2
a gas or liquid source as the source of interference is arranged downstream from a shutoff valve in the form of a quick closing valve
Implementation Method 3
The jet exiting the nozzle in a familiar matter can be supplied an abrasive in the form of a flowable substance such as sand, etc., or the form of a suspension such as a mixture of sand and water

AI summary
A method to interrupt the operation of a cutting jet exiting a cutting head having a nozzle is designed such that the cutting jet is laterally supplied with interfering means as needed following the nozzle exit which reduces the energy density of the cutting jet.
