Helical Pipe Uncapping Device for Particle Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing uncapping devices face issues with filter clogging, increased size and cost due to larger fans for air intake, and contamination during maintenance, as they require filters with porous flow passages that block over time, making maintenance difficult and increasing contamination risks.
Innovation Solution
The uncapping device incorporates a helically curved pipe portion within the air intake system, eliminating the need for filters by using centrifugal force to capture airborne particles and mist on the pipe wall, reducing apparatus size and cost, and simplifying maintenance by allowing easy cleaning and visual inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter with porous flow passages is used to remove airborne materials, then the removal capability is improved, but the fluid resistance increases over time as flow passages block, reducing air intake rate
Solution Approach 1:
The patent extracts and eliminates the filter component from the air intake system. Instead of using a filter to remove airborne materials, the system relies on the natural airflow and container geometry to prevent particles from entering the air intake, thereby avoiding the clogging and pressure drop issues associated with filters
Solution Approach 2:
The air intake system is segmented into distinct zones: a clean air intake zone positioned away from the container opening, and a particle-containing zone near the opening. This spatial segmentation allows the system to maintain reliable particle removal while preserving air intake rate by preventing contaminated air from reaching the intake path
2Reliability
If a filter is replaced when fluid resistance is doubled, then the removal capability is maintained, but the apparatus size increases and costs increase due to larger fan requirements and additional accessories
Solution Approach 1:
The filter component is completely removed from the system. The air intake device operates without any filter, eliminating the need for filter replacement mechanisms, pressure gauges, and the associated increase in device complexity and apparatus size
Solution Approach 2:
The air intake system design itself provides the particle removal function without requiring additional components like filters. The system serves its own particle removal needs through proper airflow design and positioning, eliminating the need for separate filtering subsystems
3Reliability
If a filter is used to capture airborne materials, then the removal capability is improved, but maintenance becomes difficult and contamination risk increases during filter disassembly
Solution Approach 1:
The filter is extracted from the system, eliminating maintenance difficulties and contamination risks associated with filter replacement. The air intake device operates without any removable filter components that would require maintenance intervention
Solution Approach 2:
The system maintains its particle removal capability without requiring maintenance of filtering components. The design inherently prevents particle accumulation in the air intake path, eliminating the need for filter cleaning or replacement operations
4Reliability
If a filter is used to remove mist and dust, then the removal capability is improved, but the size of the fan must be increased to maintain sufficient air intake rate
Solution Approach 1:
The filter is removed from the system, eliminating the need for oversized fans. The air intake device uses a standard-sized fan because the particle removal function is achieved through airflow design rather than filtration
Solution Approach 2:
The air intake system is segmented to separate clean air intake from particle-containing zones. This allows the use of a smaller fan since only clean air needs to be moved at high volume, while particle removal is achieved through spatial separation rather than filtration

AI summary
A device for unstopping a stopped specimen vessel that contains a liquid specimen such as blood is equipped with a mechanism which sucks and captures particles floating around the opening of the specimen vessel and prevents contamination of the specimen. The unstopping device grips a vessel and the stopper of the opening of the vessel, and removes the stopper from the opening of the vessel by changing the relative distance between the vessel-gripping mechanism and the unstopping mechanism. The unstopping device is equipped with: suction holes for sucking therethrough the gas which is present around the opening and contains liquid or solid particles; a pipeline which is connected to the suction holes and through which the sucked gas and particles are led downstream; a suction device connected to the pipeline; and a spirally flexed pipeline part disposed between the pipeline and the suction device.
