Housing Container Leakage Detection via Segmented Array
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closed-system cell culture devices face challenges in efficiently detecting liquid leakage, particularly when the configuration changes during the cell culture process, as traditional methods require pre-identification of leakage locations, which is inefficient and prone to missed detections.
Innovation Solution
A sample processing apparatus with a double structure container housing a closed-system flow channel and a detection member, where the detection member is either applied to the inner wall face or filled within the housing container, capable of detecting liquid leakage by changing color or properties upon contact, allowing for visual or automatic detection without prior location identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional liquid leakage detection methods are used in closed-system devices, then the system structure remains simple, but the detection reliability deteriorates when configuration changes occur during operation
Solution Approach 1:
The housing container is divided into a sample processing chamber (containing the closed-system flow channel) and a detection chamber (containing the detection member). This segmentation allows the detection function to be separated from the sample processing function, enabling reliable leakage detection without complicating the overall system structure. The detection member is further segmented into multiple detection elements arranged in an array, allowing comprehensive monitoring of different areas.
Solution Approach 2:
A detection member is introduced as an intermediary element between the closed-system flow channel and the external environment. This detection member changes its properties (e.g., color, electrical conductivity) when it detects liquid leakage, providing a reliable indication of leakage without requiring direct access to the sealed flow channel. The intermediary detection member enables indirect but reliable monitoring of the closed system.
2Productivity
If pre-identification of leakage locations is required, then the detection system can be simplified, but the productivity deteriorates due to inefficiency and missed detections
Solution Approach 1:
The detection member is divided into multiple detection elements arranged in a two-dimensional array pattern on the detection substrate. This segmentation allows each detection element to monitor a specific area, enabling comprehensive coverage of the entire flow channel without requiring complex targeting mechanisms. The segmented detection elements can independently indicate leakage in their respective zones.
Solution Approach 2:
The detection elements are arranged in a two-dimensional array rather than a single linear row, adding a spatial dimension to the detection capability. This two-dimensional arrangement allows simultaneous monitoring of multiple areas across the width and length of the flow channel, dramatically improving detection efficiency and coverage without proportionally increasing system complexity.
3Measurement precision
If detection members are placed only at specific predetermined locations, then the device complexity is reduced, but the measurement precision deteriorates when leakage occurs at undetected locations
Solution Approach 1:
The detection member consists of multiple discrete detection elements (e.g., 4x4 array = 16 elements) distributed across the detection substrate. This segmentation ensures that leakage at any location will be detected by at least one detection element, eliminating blind spots while maintaining a relatively simple overall structure. Each detection element independently contributes to the overall detection precision.
Solution Approach 2:
The array of detection elements provides universal coverage for the entire flow channel area, making the detection system adaptable to leakage occurrences at any position. The same detection element array can detect leakage from different sources and locations without requiring reconfiguration, providing multi-functional detection capability with a single unified structure.
