Particle Container with Adjustable Gap Width for Fluorescence Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing particle containers face challenges in efficiently filling particles into a measurement region due to varying gap widths, which can lead to particle piling and prolonged filling times, affecting fluorescence observation and other measurements.
Innovation Solution
A particle container with a measurement section that can change its gap width to accommodate multiple particles, utilizing a mechanism with flexible upper and lower plates and side portions, along with a width changing unit, to optimize particle filling and prevent particle piling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the gap width is reduced to approximately the diameter of particles to prevent piling, then measurement accuracy is improved, but the filling time is prolonged
Solution Approach 1:
The gap width between the upper and lower plates is made dynamically adjustable rather than fixed. The width changing unit allows the gap to be widened during particle filling to reduce filling time, and then narrowed to the optimal measurement width for accurate fluorescence observation, thus resolving the contradiction between filling speed and measurement precision
Solution Approach 2:
The physical parameter of gap width is changed from a static value to a variable parameter. By controlling the gap width to be larger during filling and smaller during measurement, the system optimizes both filling efficiency and measurement accuracy, addressing the trade-off between these two requirements
2Productivity
If the gap width is kept large to reduce filling time, then productivity is improved, but particles pile up during measurement
Solution Approach 1:
The system dynamically adjusts the gap width based on the operational phase: wider gap during filling to maximize productivity, and narrower gap during measurement to prevent particle piling and ensure accurate fluorescence observation
Solution Approach 2:
The gap width is pre-adjusted to a larger value before filling begins to maximize filling speed, and then adjusted to the optimal measurement value before measurement starts, ensuring both high productivity and measurement accuracy
