Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing purification instruments face the risk of microplastic leakage during the discharge of waste solutions due to the introduction and discharge of decomposition and cleaning solutions.
Innovation Solution
A purification apparatus with a strainer arranged in the container to catch and hold the target substance, preventing its leakage during the discharge of waste solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a discharge port is provided in the container to discharge treatment solution, then the treatment solution can be discharged from the container, but the target substance may leak together with the treatment solution
Solution Approach 1:
The discharge system is segmented into two functional components: the discharge port for liquid flow and the strainer for substance retention. The strainer is positioned within the container near the discharge port, creating a segmented structure where the container body handles liquid discharge while the strainer component specifically retains the target substance. This segmentation allows the discharge function to operate effectively while preventing substance leakage.
Solution Approach 2:
The strainer acts as an intermediary component between the treatment solution and the discharge port. It mediates the discharge process by allowing the treatment solution to pass through while intercepting and retaining the target substance. This intermediary structure resolves the contradiction by enabling liquid flow while preventing substance leakage.
2Reliability
If a strainer is arranged in the container to prevent target substance leakage, then the target substance can be retained, but the discharge efficiency of the treatment solution may be reduced
Solution Approach 1:
The strainer is designed with localized mesh structures concentrated at the discharge port area, rather than covering the entire container. This local quality approach ensures that the strainer only interferes with the discharge process where necessary (at the discharge port) while maintaining efficient flow in the broader container volume. The mesh configuration is optimized to provide adequate filtration without creating excessive flow resistance.
Solution Approach 2:
The strainer utilizes porous mesh materials that allow treatment solution to pass through while retaining the target substance. The porous structure provides sufficient open area for efficient liquid discharge while maintaining the filtration function. The pore size and distribution are optimized to balance discharge efficiency with substance retention capability.

AI summary
A purification apparatus separates a target substance contained in a mixed sample based on a specific gravity difference. The purification apparatus includes a container that receives the mixed sample and a strainer arranged in the container. The container includes an introduction port to introduce a treatment solution for treatment of the mixed sample into the container and a discharge port to discharge the treatment solution from the container. The strainer is configured to catch the target substance in the treatment solution discharged through the discharge port and to hold the target substance in the container.
