Cell Strainer Grip Segmentation for Stackable Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cell strainers face issues with low collection rates of filtration targets, difficulty in stacking and using multiple strainers due to integrated grip portions, and interference during observation, leading to decreased processing efficiency and increased processing time.
Innovation Solution
A filtration and collection device with a separate filter and grip section, featuring a holder with a groove portion and insertion portion, allowing for improved ventilation and vibration, and a filter with uniform through-holes to enhance collection efficiency and reduce clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cell strainer with an integrated grip portion is used, then the device is easy to hold and operate, but multiple strainers cannot be stacked and used simultaneously due to interference between grip portions
Solution Approach 1:
The device is divided into separate functional components: a holder with groove portion and a grip section with insertion portion. This segmentation allows the grip section to be detached or positioned separately, enabling multiple devices to be stacked without grip portion interference while maintaining ease of operation through the integrated holder design.
2Device complexity
If the grip portion is integrated with the holder, then the structure is simple, but the grip portion interferes with observation and reduces processing efficiency
Solution Approach 1:
By separating the grip section from the holder body, the design reduces interference during observation and processing operations. The grip section can be positioned to the side or detached, eliminating obstruction while maintaining structural simplicity through modular construction.
Solution Approach 2:
The grip function is extracted as a separate section that can be independently positioned or removed. This allows the main holder body to remain unobstructed for observation and processing, improving productivity while maintaining ease of operation through the separate grip section.
3Ease of manufacture
If a filter with non-uniform through-holes is used, then manufacturing is simpler, but the collection rate of filtration targets is low and clogging occurs frequently
Solution Approach 1:
The through-holes in the filter are designed with uniform size, shape, and distribution parameters. This uniformity improves the collection rate of filtration targets by ensuring consistent filtration performance and reduces clogging by preventing preferential flow paths, while still allowing for straightforward manufacturing through standard filtration techniques.

AI summary
A filtration and collection device capable of improving the collection rate of filtration targets. The filtration and collection device may include a holder having an inlet port for pouring a liquid, a discharge port for discharging the liquid, a flow path through which the inlet port and the discharge port communicate, and a groove portion formed on an outer periphery of the holder, a filter disposed in the flow path of the holder and having a plurality of through-holes, and one or a plurality of grip sections having an insertion portion that is inserted into the groove portion, in which a gap is formed between the groove portion and the insertion portion.
