Rotating Nozzle Holder for High Impact Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spray nozzles deliver a fan-shaped fluid pattern with relatively small impact energy due to atomization, requiring higher volumes and pressures to achieve effective cleaning, which limits their efficiency.
Innovation Solution
A high impact spray nozzle design featuring a housing with a perpendicular axis inlet and nose cone, including a nozzle holder that rotates within a conical path, directing a fluid stream to enhance surface impact energy while reducing energy loss through a conical spray pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a fan-shaped fluid pattern is projected to provide cleaning coverage, then the cleaning coverage area is improved, but the impact energy delivered to the surface deteriorates
Solution Approach 1:
The nozzle holder is designed to rotate dynamically within the housing, transforming a static spray pattern into a dynamic one. This rotation allows the nozzle to deliver concentrated impact energy to the surface while progressively covering a larger area over time, resolving the contradiction between coverage area and impact energy
Solution Approach 2:
The rotating nozzle holder creates a periodic spray action where the fluid stream is delivered in repeated cycles to the same area. This periodic impact accumulates cleaning effect over time while maintaining high impact energy during each spray cycle, achieving both coverage and impact force
2Area of stationary object
If fluid is atomized to form a fan pattern, then the cleaning coverage is improved, but the energy loss increases
Solution Approach 1:
By making the nozzle holder rotatable rather than fixed, the system dynamically adjusts the spray delivery. The rotation allows concentrated fluid streams to be delivered sequentially to different areas, reducing the energy waste associated with simultaneous atomization across the entire fan pattern while maintaining comprehensive coverage
Solution Approach 2:
The rotating nozzle holder ensures continuous useful action by maintaining constant motion and refreshing the spray impact on the surface. This continuous dynamic operation prevents energy loss that would occur with static atomization, as the moving nozzle delivers fresh concentrated streams continuously across the coverage area

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The nozzle provides increased cleaning coverage area with reduced pressure and volume, achieving superior surface impact for removing contaminants like bone dust and blood clots, compared to traditional fan-spray nozzles.
Implementation Method 1
A distal end of a nozzle holder, in some embodiments, is free to rotate within an internal chamber of a housing along a conical path having a vertex at approximately a nozzle seat of a body
