Detachable Spray Arm Nozzles for Full Disinfection Chamber Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disinfection devices often fail to achieve a satisfactory degree of cleanliness due to inadequate spray patterns that do not cover the entire disinfection chamber, and dirt and particles can stick to the device, making cleaning inefficient and difficult.
Innovation Solution
A rotatable spray arm with detachable nozzle devices that produce a directional spray pattern, allowing for easy cleaning and efficient manufacturing using the same tools for different sizes, with outlet nozzles oriented transversely to the plane of rotation for improved coverage and a symmetrical configuration for user-friendliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spray means is designed to cover the entire disinfection chamber, then the cleaning effectiveness is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The spray arm is divided into a permanent body portion and a detachable nozzle device. The nozzle device can be removed and replaced to change spray patterns, allowing comprehensive chamber coverage without permanently complex design. Different nozzle configurations can address different cleaning requirements.
Solution Approach 2:
The spray system allows dynamic reconfiguration by detaching and reattaching nozzle devices. This enables the spray pattern to be adapted for different disinfection chamber configurations and cleaning needs, improving overall coverage effectiveness without permanent complexity.
2Ease of manufacture
If the spray arm is designed as a single integrated piece, then the manufacturing process is simpler, but the cleaning of the spray arm itself becomes difficult due to dirt and particles sticking
Solution Approach 1:
The spray arm is segmented into a permanent body and a detachable nozzle device. The detachable nozzle device can be removed for separate cleaning, allowing the main spray arm body to be cleaned more easily without disassembling the entire assembly. This resolves the cleaning difficulty while maintaining manufacturing simplicity.
Solution Approach 2:
The nozzle device is extracted as a separate detachable component from the spray arm body. This allows the nozzle device to be removed for cleaning or replacement, making maintenance easier while the spray arm body remains a simpler, easier-to-manufacture component.
3Manufacturing precision
If different sized spray arms are manufactured separately with dedicated tools, then the manufacturing precision is maintained, but the manufacturing time and cost increase
Solution Approach 1:
The spray arm body is designed as a universal platform that can accommodate different sized nozzle devices. The same spray arm body can be used across different disinfection chamber sizes by simply changing the detachable nozzle device, eliminating the need for dedicated manufacturing tools for each size and improving productivity while maintaining precision through standardized interfaces.

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 solution ensures a more efficient and effective cleaning process by achieving a comprehensive spray pattern that reaches all areas, including corners, and simplifies maintenance by allowing easy removal and reassembly of the nozzle devices, enhancing user experience and manufacturing efficiency.
