Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid jet receptacles in cutting systems are often complex, bulky, and prone to premature wear, leading to rebound issues and surface defects in workpieces during cutting operations.
Innovation Solution
A compact fluid jet system with a rotatable inlet feed component featuring a tapered inlet surface and a drive mechanism to distribute the fluid jet impact continuously or intermittently, reducing wear and rebound by directing the jet over a large wear area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact fluid jet receptacle is used, then the system size is reduced and positioning is simplified, but the receptacle components are prone to premature wear and rebound issues
Solution Approach 1:
The inlet feed component is made rotatable rather than stationary, allowing it to dynamically distribute the fluid jet impact across its entire tapered surface area. This rotational movement prevents localized wear by continuously changing the impact zone, thereby resolving the contradiction between compact size and wear resistance.
Solution Approach 2:
The solution transitions from a static single-point impact scenario to a dynamic multi-point impact scenario by rotating the inlet feed component. This adds the dimension of time and spatial distribution, spreading the wear across the entire tapered surface rather than concentrating it at one location.
2Device complexity
If the fluid jet impact is concentrated on a small area, then the receptacle structure is simpler, but wear occurs prematurely and causes rebound leading to surface defects
Solution Approach 1:
The rotatable inlet feed component dynamically distributes the jet impact across its tapered surface, preventing localized wear that would cause rebound. This maintains manufacturing precision by ensuring consistent surface quality without requiring complex additional structures.
Solution Approach 2:
The high-velocity fluid jet, which causes harmful localized wear and rebound, is converted into a beneficial distributed impact across the entire tapered surface through rotation. The harmful concentrated force is transformed into a beneficial distributed force that protects workpiece surface quality.
3Device complexity
If a stationary receptacle is used, then the design is simpler, but the jet impact causes excessive wear and rebound
Solution Approach 1:
The stationary receptacle design is transformed into a dynamic system with a rotatable inlet feed component. This rotation distributes the jet impact across the entire tapered surface, eliminating excessive wear and preventing fluid and abrasive rebound while maintaining relatively simple overall design.
Solution Approach 2:
The inlet feed component performs periodic rotation to continuously present different portions of its tapered surface to the fluid jet impact. This periodic movement ensures that no single location is subjected to continuous wear, thereby preventing rebound and maintaining system reliability.

AI summary
A jet receiving receptacle is provided which is coupleable to a high pressure fluid jet system opposite a nozzle thereof to receive a fluid jet discharged from the nozzle after it acts on a workpiece. The jet receiving receptacle may include an inlet feed component having a tapered inlet that defines a jet receiving surface about a central axis to receive the fluid jet and direct the fluid jet downstream and toward the central axis. The jet receiving receptacle may further include a drive mechanism adapted to rotate the inlet feed component about the central axis such that impact of the fluid jet with the inlet feed component is distributed around the jet receiving surface. The drive mechanism may rotate the inlet feed component continuously or intermittently. Fluid jet cutting systems incorporating a jet receiving receptacle and related methods are also provided.
