Solution Overview
Problem
Nucleic acid testing integrated machines occupy excessive space due to the cooperation of multiple modules required for DNA extraction and replication.
Innovation Solution
A compact to-be-tested object extraction apparatus is designed with a to-be-tested object loading area, sample reaction area, and grabbing area arranged around the sample reaction area, featuring transfer pieces for moving reaction vessels and consumables, allowing for efficient nucleic acid extraction and replication while reducing machine size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple modules are used for DNA extraction and replication, then the nucleic acid testing function is complete, but the occupied area of the machine becomes too large
Solution Approach 1:
The patent combines multiple functional modules (loading module, reaction module, adding module, grabbing module) into a compact integrated structure where modules share common components and spatial relationships. The grabbing portion serves multiple modules simultaneously, and the central reaction area is accessible from all directions, reducing the overall footprint while maintaining complete nucleic acid testing functionality.
2Area of stationary object
If modules are arranged in a compact configuration, then the occupied area is reduced, but the ease of operation may be affected
Solution Approach 1:
The patent employs asymmetric arrangement where the grabbing area is positioned on one side to access all modules efficiently. The loading area, reaction area, and adding area are arranged around the sample reaction area in an asymmetric circular pattern, allowing compact positioning while maintaining operational accessibility through the strategically placed grabbing portion.
