Sample Container Storage With Vertical Cap Gripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample storage and retrieval systems face inefficiencies due to the need for grippers to extend between adjacent sample containers, limiting the density of containers that can be held in a tray and complicating transport operations.
Innovation Solution
A gripper interface that grips sample containers from within the peripheral bounds of the cap, allowing for a closely packed array of containers without extending between them, combined with a self-centering mechanism for accurate placement and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gripper extends between adjacent sample containers to grip them, then the sample containers can be securely held for transport, but the spacing between containers increases, reducing the number of containers that can be held in a tray
Solution Approach 1:
The gripper interface is moved from a lateral approach (extending between containers) to a vertical approach (accessing the cap from above). This dimensional change allows the gripper to engage the cap without requiring lateral clearance between containers, thereby increasing storage density while maintaining secure gripping.
Solution Approach 2:
The gripping function is extracted from the lateral spacing requirement and relocated to the cap structure. By incorporating a dedicated gripping interface on the cap, the system eliminates the need for lateral clearance, allowing containers to be closely packed while still enabling reliable gripping through the cap's protrusion or cavity.
2Ease of operation
If the gripper extends between adjacent sample containers, then the sample containers can be gripped for transport, but the tray design becomes more complex and the number of containers per tray is reduced
Solution Approach 1:
The cap structure is given multiple functions: it protects the sample container opening and simultaneously provides a gripping interface for the automated handling system. This multi-functionality eliminates the need for separate gripping mechanisms or complex tray designs, simplifying the overall system while maintaining ease of operation.
Solution Approach 2:
The cap structure itself provides the gripping interface through its geometry (protrusion or cavity), eliminating the need for external gripping mechanisms. The cap's own structure enables the gripping function, reducing tray design complexity and simplifying the automated handling system.
3Quantity of substance
If sample containers are closely packed in the tray, then the number of containers per tray increases, but access for gripping becomes more difficult
Solution Approach 1:
The gripping access is moved from the lateral dimension (between containers) to the vertical dimension (above the cap). This allows the gripper to access the gripping interface on the cap from above, independent of the lateral spacing between containers, enabling closely packed arrangements while maintaining ease of operation.
