Pipette Tip Platform Loader for Secure Downward Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for alternative, reusable loading devices that can efficiently and reliably dispense units of platform-loaded pipette tips in a single action, minimizing the inconvenience of handling individual tips and reducing the risk of jostling or dislodging during transfer.
Innovation Solution
A system comprising a loader made of clear, semi-rigid thermoplastic polymer resin with flared sides and indentations forming shelves, allowing for secure transport and release of pipette tip platforms from packaging to a rack using a downward motion, which minimizes the risk of tips being jostled or dislodged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling of individual pipette tips is used, then flexibility in handling is maintained, but handling efficiency and convenience deteriorate
Solution Approach 1:
The invention segments the pipette tip storage into modular platforms, each holding multiple tips in a grid array. Users can handle entire platforms rather than individual tips, significantly improving efficiency while maintaining the ability to access specific tips when needed.
Solution Approach 2:
The loader acts as an intermediary device that automatically transfers platforms from packaging to the rack. This intermediary mechanism eliminates the need for manual manipulation of individual tips while ensuring precise and secure placement.
2Reliability
If platforms are transferred manually from packaging to rack, then device complexity is minimized, but transfer reliability and precision deteriorate
Solution Approach 1:
The loader is designed to automatically perform the transfer operation without requiring complex external mechanisms. The user simply places the platform on the loader, and the loader's flared sides and shelves automatically guide and secure the platform during transfer to the rack.
Solution Approach 2:
The loader incorporates flared sides made of flexible material that can deform during the transfer process to accommodate the platform, then return to their original shape to secure the platform in place. This flexibility enhances transfer reliability without adding mechanical complexity.
3Productivity
If downward force is applied to release platform from loader, then transfer speed is improved, but risk of jostling or dislodging pipette tips increases
Solution Approach 1:
The loader's flared sides and shelves are designed to cushion and support the platform during the downward release motion. The gradual flaring provides a gentle guiding surface that prevents sudden movements or jostling of the pipette tips while still enabling rapid transfer.
Solution Approach 2:
The flared sides of the loader use curved surfaces to guide the platform during transfer. The curved geometry distributes forces evenly and prevents sharp impacts that could dislodge pipette tips, while still allowing for quick and efficient platform release.
4Ease of manufacture
If reusable loading devices are used, then cost efficiency is improved, but device complexity and cleaning requirements increase
Solution Approach 1:
The loader is designed as a reusable component that can be easily cleaned and recovered for repeated use. The simple geometry with flared sides and shelves minimizes crevices and complex surfaces that would be difficult to clean, making maintenance straightforward while providing cost savings through reusability.
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 system enables secure and efficient transfer of pipette tip platforms from packaging to a rack using a downward force, reducing the likelihood of tips being dislodged and allowing for easy alignment and insertion into the rack, thus improving handling efficiency.
Implementation Method 1
The loader in general may be formed of a clear, semi-rigid, thermoplastic polymer resin having a degree of elasticity
