Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid sterilization devices using ultraviolet light suffer from reduced sterilization performance due to staining on the inner pipe walls, requiring periodic disassembly and cleaning, which leads to prolonged downtime.
Innovation Solution
A fluid sterilization device with a rotating body that contacts the inner wall of the pipe, utilizing ultraviolet transmissive or reflective materials, and a torque generator to remove stains while in operation, eliminating the need for extra space and a drive source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device is disassembled and cleaned periodically, then the stain on the inner wall is removed, but the device must be stopped and downtime increases
Solution Approach 1:
The rotating body automatically cleans the inner wall of the flow passage tube during normal operation by rotating and contacting the wall surface. The fluid flow itself drives the rotation of the cleaning body, enabling the system to clean itself without external intervention or shutdown, thus maintaining sterilization performance while eliminating downtime
Solution Approach 2:
The cleaning action continues uninterrupted during fluid flow operation. The rotating body constantly contacts and cleans the inner wall surface as fluid passes through, ensuring continuous sterilization performance without periodic shutdowns for maintenance
2Ease of manufacture
If a rotating cleaning body is added to the flow passage tube, then stain removal capability is provided, but the device complexity increases
Solution Approach 1:
The fluid flow itself provides the driving force for rotating the cleaning body, eliminating the need for external motors or drive mechanisms. The system uses its own operating fluid to power the cleaning function, adding minimal complexity while achieving effective stain removal
Solution Approach 2:
The rotating body serves dual functions: it acts as both a flow element within the passage and a cleaning mechanism. The same structural component facilitates both fluid flow and wall cleaning, reducing overall device complexity compared to separate dedicated cleaning systems
Applied Scientific Principles
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 rotating body effectively removes stains from the inner pipe walls during continuous use, maintaining sterilization performance and reducing downtime by integrating with the existing flow passage without additional space or drive requirements.
Implementation Method 1
The rotating body is rotated around a longitudinal direction of the processing passage in response to a flow of the fluid passing through the processing passage
Implementation Method 2
The rotating body is configured to come into contact with an inner wall of the flow passage tube during rotation
Implementation Method 3
a rotating body provided in the processing passage and configured to come into contact with an inner wall of the flow passage tube during rotation
Implementation Method 4
a light source that irradiates the processing passage with ultraviolet light

AI summary
A fluid sterilization device includes: a flow passage tube in which a processing passage where a passing fluid is sterilized is formed; an inflow passage or an outflow passage formed in the flow passage tube; a light source that irradiates the processing passage with ultraviolet light; and a rotating body provided in the processing passage. The rotating body is rotated around a longitudinal direction of the processing passage in response to a flow of the fluid passing through the processing passage and is configured to come into contact with an inner wall of the flow passage tube during rotation.
