Spray Cleaner Head Dual-Axis Rotation Gear System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray cleaner heads for concrete mixer drums are inefficient in removing hardened concrete due to limited rotational axes and lack of effective gear systems to regulate nozzle rotation, leading to incomplete cleaning and increased weight from residual concrete.
Innovation Solution
A spray cleaner head with at least two axes of rotation, incorporating a gear system and adjustable brake assembly to regulate nozzle rotation, ensuring thorough cleaning and efficient fluid distribution through multiple orifices sealed to maintain pressure and reduce bearing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a spray cleaner head has limited rotational axes, then the device complexity is reduced, but the cleaning effectiveness deteriorates due to incomplete coverage
Solution Approach 1:
The spray cleaner head transitions from single-axis rotation to dual-axis rotation, adding a second dimension of motion. This allows the nozzle to rotate about a first axis and a second axis that is non-collinear with the first axis, enabling the spray to cover a complete spherical pattern and eliminate blind spots in the cleaning process.
2Device complexity
If no gear system is used to regulate nozzle rotation, then the device complexity is reduced, but the cleaning precision deteriorates due to inability to control spray pattern
Solution Approach 1:
A gear system is incorporated into the spray cleaner head to provide mechanical feedback control for nozzle rotation. The gear system regulates the rotational motion of the nozzle, ensuring precise control over the spray pattern and maintaining consistent cleaning coverage across the entire surface.
3Device complexity
If seals are not provided at orifices, then the device complexity is reduced, but the pressure control deteriorates leading to fluid leakage
Solution Approach 1:
Seals are strategically positioned at the orifices of the spray cleaner head to extract and prevent fluid leakage. The seals maintain pressure integrity at critical points where fluid passes through the orifices, ensuring efficient fluid delivery without compromise.
4Quantity of substance
If multiple orifices are used without proper sealing, then the fluid distribution is improved, but the pressure loss increases due to leakage
Solution Approach 1:
Seals are installed at each orifice to prevent fluid leakage and maintain pressure. This allows multiple orifices to be used for improved fluid distribution while preventing energy loss through pressure loss, as the seals ensure that fluid is delivered efficiently through each orifice without compromising the overall pressure system.
