Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adapters for laboratory cell strainer systems are not versatile enough to fit various sized tubes, lack stability and security, have sharp surfaces that retain liquids, and fail to prevent air-lock issues, leading to inefficient liquid transfer.
Innovation Solution
A unitary adapter with a downwardly and radially inwardly sloped funnel section, featuring a tapered diameter and vertically oriented radially protruding ribs, designed for secure fit and air-lock prevention, allowing filtered liquids to flow freely into various sized laboratory tubes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single conventional adapter design is used, then the device complexity is reduced, but the adaptability to various sized tubes deteriorates
Solution Approach 1:
The adapter incorporates a funnel section with a tapered diameter that can accommodate various sized laboratory tubes. The tapered design allows the same adapter structure to fit multiple tube diameters, eliminating the need for multiple specialized adapters for different tube sizes.
2Ease of manufacture
If conventional adapter designs are used, then the manufacturing process is simplified, but the stability and security of fit deteriorates
Solution Approach 1:
The adapter features a funnel section with a specific tapered diameter configuration that provides enhanced stability and security. The tapered geometry creates a friction fit that secures the adapter firmly within the tube while maintaining ease of manufacture through a single integrated design.
3Productivity
If smooth interior surfaces are used, then the liquid flow is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The adapter incorporates a funnel section with a tapered diameter that provides smooth, curved interior surfaces. This curved geometry eliminates sharp edges that would retain liquid, facilitating complete liquid transfer while the tapering design allows these smooth surfaces to be achieved through standard manufacturing processes.
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 adapter provides a stable and secure fit within various sized tubes, prevents air-lock, and ensures smooth liquid transfer without residual liquid, reducing spillage and improving handling efficiency.
Implementation Method 1
a downwardly and radially inwardly sloped funnel section wherein the tunnel section has an upper section with a first slope, a middle section with a second slope, section terminating in a cylindrical edge at the annular bottom surface with a lower section of the funnel section having a narrowed, tapered diameter
Implementation Method 2
The plurality of radially protruding ribs are configured for preventing air lock, thereby allowing the filtered liquid to flow freely into the various sized laboratory tube during use
Implementation Method 3
a downwardly and radially inwardly sloped funnel section wherein the tunnel section has an upper section with a first slope, a middle section with a second slope
