Sample Storage With Cap-Access Gripping for Dense Container Trays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample storage and retrieval systems face challenges in efficiently handling and transporting sample containers due to the need for grippers to extend between adjacent containers, limiting the density of containers that can be held in a tray and complicating the transfer process.
Innovation Solution
A gripper system that interfaces with the cap of the sample container instead of extending between adjacent containers, allowing for a closely packed arrangement of containers and enabling efficient transfer and storage, with features like self-centering and minimal clearance for gripper access.
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 moves from a lateral approach (extending between containers) to a vertical approach (accessing the cap from above), changing the dimensional space the gripper occupies and eliminating the need for lateral clearance between containers
Solution Approach 2:
The cap structure itself provides the gripping interface through its geometry, eliminating the need for external gripping structures that would require additional space between containers
2Ease of operation
If the gripper extends between adjacent sample containers, then the sample containers can be gripped for transport, but the device complexity increases due to the need for lateral access clearance
Solution Approach 1:
The gripper accesses the sample container from the vertical dimension (top of cap) rather than the horizontal dimension (between containers), simplifying the mechanical requirements and eliminating lateral access constraints
Solution Approach 2:
The cap serves dual functions: sealing the sample container and providing a gripping interface, eliminating the need for separate gripping mechanisms and reducing overall system complexity

AI summary
A sample storage including a frame and an array of sample container holding areas disposed within the frame where a spacing between adjacent sample container holding areas is independent of a gripping area for sample containers held by the sample storage.
