Pipette Tip Straight Pipe Section for Cell Breakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipette tips do not adequately address cell breakage and irregularity in diameter during pipetting, which affects cell aggregation and dispersion, leading to inefficient cell processing.
Innovation Solution
A pipette tip with a straight pipe section having an inner diameter of 1.0 mm to 1.5 mm and a length of 5 mm to 15 mm, designed to minimize diameter irregularity and facilitate effective cell suspension handling through controlled sucking and discharging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional pipette tips with varied diameters are used, then liquid transport function is achieved, but cell breakage control and diameter irregularity increase
Solution Approach 1:
The patent applies parameter changes by specifying precise dimensional parameters for the straight pipe section: inner diameter of 1.0-1.5mm and length of 5-15mm. This quantitative parameter optimization resolves the contradiction by controlling diameter irregularity while maintaining effective cell breakage functionality through the defined geometric parameters.
Solution Approach 2:
The patent applies local quality by creating a straight pipe section with uniform diameter at the leading end, distinct from other sections of the pipette tip. This localized uniformity in the straight pipe section specifically addresses diameter irregularity while the overall tip structure maintains its liquid transport capabilities, thus resolving the contradiction between precision and operational effectiveness.
2Manufacturing precision
If pipette tip with straight pipe section is used, then cell aggregation control is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the pipette tip into distinct functional sections: a straight pipe section at the leading end and a main body section. This segmentation allows the straight pipe section to specifically control cell aggregation uniformity while the main body maintains standard pipette tip functionality, thus improving precision without excessive complexity increase.
