Observation Container Flat Plate Intersection for Microparticle Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing observation containers distort images of microparticles due to light refraction from their three-dimensional shape, making it difficult to calculate the microparticles' three-dimensional shape with high accuracy.
Innovation Solution
An observation container with intersecting first and second plate parts, where both parts have flat surfaces and a region transparent to the observation wavelength, allowing for accurate imaging of microparticles from multiple directions, with the line of intersection of the plate parts' surfaces close to the central portion and a radius of curvature between 1 mm to 10 mm, facilitating precise imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional three-dimensional observation container is used, then the container can accommodate samples, but light refraction occurs due to the three-dimensional shape causing image distortion
Solution Approach 1:
The bottom portion is segmented into two separate plate parts (first and second plate parts) that intersect each other. This segmentation allows each plate to have a flat configuration, preventing light refraction while still providing the necessary structural support for the observation container.
Solution Approach 2:
The solution transitions from a conventional three-dimensional curved bottom to a two-dimensional flat plate intersection structure. By placing two flat plates perpendicular to each other, the design eliminates the curved surface that causes refraction while maintaining the container's functionality.
2Measurement precision
If the plate parts have flat surfaces, then light refraction is minimized, but the structural complexity increases with intersecting plates
Solution Approach 1:
The two flat plate parts are merged at their intersection to form a unified bottom structure. This combining approach simplifies the overall design compared to using curved surfaces, as flat plates are easier to manufacture and assemble while still achieving the refraction-free imaging goal.

AI summary
An observation container (10) includes: a bottom portion that includes a bottom wall (12A) (first plate part) and a bottom wall (12B) (second plate part) which intersect each other and that is configured to accommodate a liquid sample O as a sample containing microparticles to be imaged by imaging units (30A) and (30B) serving as an imaging device; and a region that has transparency with respect to a wavelength of light used for observation of the microparticles.
