Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for collecting biological nucleic acids from terrestrial organisms are limited, as they often decompose in water and are difficult to sample over wide areas, particularly in dry land environments, where they are more stable.
Innovation Solution
A biological nucleic acid collection method and apparatus that uses a rotation body to collect nucleic acids-containing sediment from the ground surface, allowing for exhaustive sampling by rotating the body in contact with the ground, which includes collectors to efficiently gather and extract nucleic acids from a wide range of species.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If water samples are collected for environmental DNA analysis, then nucleic acids of aquatic organisms can be collected, but the method cannot collect nucleic acids of terrestrial organisms and the collection range is limited
Solution Approach 1:
The invention changes the sampling medium from water to dry land surface, exploiting the parameter difference in nucleic acid stability between aqueous and terrestrial environments. This allows collection of terrestrial organism nucleic acids while improving preservation quality through the dry state that prevents decomposition
Solution Approach 2:
The rotation body is designed to collect nucleic acids from the dry surface of land, enabling the system to universally collect nucleic acids from both aquatic and terrestrial organisms by adapting to different environments, thereby expanding the collection range beyond water-only sampling
2Quantity of substance
If soil is collected for environmental DNA analysis in land areas, then terrestrial organism nucleic acids can be collected, but sampling in a wide range is difficult
Solution Approach 1:
The invention replaces static soil sampling with a dynamic rotation body that moves across the land surface. The rotation body's movement and rotation enable continuous contact with different ground areas, dramatically improving sampling efficiency and the ability to collect samples over wide ranges while maintaining nucleic acid stability through dry contact
Solution Approach 2:
The rotation body automatically collects nucleic acids from the ground surface through its own rotation and movement, eliminating the need for manual soil sampling operations. The system serves itself by using the rotation body's contact with the ground to naturally accumulate nucleic acid-containing sediment
3Area of stationary object
If a rotation body is used to collect nucleic acids from the ground surface, then sampling coverage is improved, but device complexity increases
Solution Approach 1:
The rotation body serves multiple functions: it acts as both the sampling surface that contacts the ground and the collection mechanism that accumulates nucleic acids. This multi-functionality reduces the need for separate complex sampling mechanisms while expanding sampling coverage through the rotation body's movement and rotation
