Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test methods for microbial barrier properties of sterile products do not provide adequate information on microbe distribution in three-dimensional space, leading to partial testing and potential weak points being overlooked during transportation under changing conditions.
Innovation Solution
A test specimen with multiple measuring surfaces, each equipped with microbe collecting elements such as through-holes or vessels, allows for the determination of microbe distribution in three-dimensional space, using microbe detecting elements like nutrient-coated plates or dishes to collect and cultivate microbes, ensuring comprehensive testing of products for microbial barrier properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional test methods are used to test microbial barrier properties, then the testing process is simple, but the information about microbe distribution in three-dimensional space is insufficient
Solution Approach 1:
The test specimen is divided into multiple measuring surfaces (first, second, third, fourth measuring surfaces) with microbe collecting elements distributed across each surface. This segmentation allows comprehensive collection of microbes from different spatial locations and orientations, providing complete three-dimensional distribution information without requiring a single complex detection system.
Solution Approach 2:
The invention transitions from traditional single-point or surface-level microbe detection to three-dimensional spatial distribution detection. By arranging measuring surfaces and microbe collecting elements in multiple orientations and positions within the test specimen, the system captures microbe distribution across volumetric space, adding spatial dimensionality to the measurement.
2Reliability
If only sedimentation-reachable locations are tested, then the testing process is simple, but weak points of the product are not tested sufficiently
Solution Approach 1:
The test specimen incorporates multiple measuring surfaces oriented in different directions (front, back, left, right sides) with microbe collecting elements distributed across each surface. This segmentation ensures that microbes can be collected from all sides of the product under test, not just locations accessible by sedimentation, thereby identifying weak points throughout the entire product structure.
Solution Approach 2:
Different measuring surfaces are positioned to face different directions and collect microbes from specific local regions. Each measuring surface with its microbe collecting elements is optimized for detecting microbes in its specific orientation and location, ensuring comprehensive coverage of all product surfaces including those previously inaccessible to sedimentation.
