Tube Rack Tool Synchronized Removal Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microtiter plate systems face difficulties in efficiently and safely removing multiple tubes from a rack, as manual removal can lead to contamination and spillage of hazardous materials.
Innovation Solution
A tube rack tool comprising a base with a surface for engaging the tubes and a top piece that applies pressure to dislodge multiple tubes simultaneously from the rack, allowing for synchronized removal without engaging the rack, thereby preventing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual removal of tubes from the rack is performed, then tubes can be removed one at a time, but the process is time-consuming and increases the risk of contamination and spillage
Solution Approach 1:
The patent combines multiple tube removal actions into a single synchronized operation. The tool engages multiple tubes simultaneously across different rows and uses a single rocking motion to dislodge all engaged tubes at once, transforming the sequential manual removal process into a parallel automated operation that increases productivity while minimizing contamination risk
Solution Approach 2:
The tool performs preliminary engagement with multiple tubes before the actual removal action. The engagement surface contacts and secures multiple tubes in position prior to the rocking motion, ensuring proper alignment and grip. This preliminary engagement phase allows the subsequent removal action to be executed efficiently and safely without contamination risk
2Reliability
If a tool engages the rack to remove tubes, then tubes can be held securely during removal, but the rack itself may be damaged or the engagement mechanism becomes more complex
Solution Approach 1:
The patent extracts the engagement function from the rack structure itself and places it on a separate removable tool. The engagement surface is a distinct component that can be attached to and removed from the tool body, allowing the rack to remain simple while the tool provides the necessary gripping and holding capabilities during tube removal operations

AI summary
Tools and methods are provided for removing a plurality of tubes from a rack of tubes. Tube rack tools include a base and/or top piece for receiving the rack of tubes. The base has a support surface for engaging the closed bottom of the plurality of tubes. The support surface can be curved such that the rack of tubes can be rocked about the curves support surface to dislodge the plurality of tubes from the rack. The top piece can be configured to engage the rack such that pressure on the top piece in the direction of the support surface applies a pressure on the rack without applying the pressure to the tubes. The tubes are dislodged from the rack by application of the pressure. Elements of the tube rack tool are also configured for securing the tubes within the rack or caps to the tubes.
