Resilient Panel Centrifuge Support for Bag Shape Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centrifuge receptacles often deform during centrifugation due to changed mass distribution, leading to incomplete separation of sample materials and difficulties in removing deformed containers, particularly affecting blood analysis.
Innovation Solution
A resiliently flexible panel is placed in the centrifuge receptacle, capable of bending to support and brace the sample container, maintaining its original shape through restoring forces, and can be adapted to different container sizes by adjusting the bending axis, with a handling element for controlled release during centrifugation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid support structure is used to maintain container shape, then shape stability is improved, but adaptability to different container sizes is worsened
Solution Approach 1:
The support device uses a flexible panel that can be bent to different angles to adapt to various container sizes while maintaining shape stability during centrifugation. The panel's flexibility allows it to conform to different container geometries, resolving the contradiction between rigidity for shape maintenance and flexibility for adaptability.
Solution Approach 2:
The support device incorporates a dynamically adjustable panel that can be bent to different angles during installation to match different container sizes. This dynamic adjustment capability allows the same device to maintain optimal shape support across multiple container types, resolving the contradiction between fixed rigid support and variable adaptability.
2Adaptability or versatility
If a flexible support device is used to adapt to different container sizes, then adaptability is improved, but shape retention capability is worsened
Solution Approach 1:
The flexible panel is designed with specific material properties and dimensions that allow it to adapt to different container sizes while generating sufficient restoring force to maintain shape stability during centrifugation. The panel's flexibility enables adaptation, while its elastic properties ensure shape retention.
Solution Approach 2:
The support device utilizes changes in the panel's bending angle as a key parameter to adapt to different container sizes. By adjusting the bending angle during installation, the device maintains optimal contact and support for various container geometries while preserving shape stability through the panel's elastic restoring force.
3Stability of the object's composition
If the panel is made more rigid to improve shape maintenance, then shape stability is improved, but ease of installation and handling is worsened
Solution Approach 1:
The panel is constructed from a flexible material that can be easily bent and positioned during installation, yet generates sufficient restoring force to maintain container shape during centrifugation. This resolves the contradiction between rigidity for shape maintenance and flexibility for ease of installation.
Solution Approach 2:
The panel's material properties and dimensions are specifically selected to provide optimal balance between flexibility for handling and rigidity for shape maintenance. The restoring force characteristics are tuned through material selection and dimensional design to ensure both ease of installation and effective shape support during operation.
