Analyzer Container Placement Detection Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional analyzers lack the ability to confirm whether a sample container is correctly placed and fail to accurately determine the number of detection containers needed for multiple assays, leading to usability issues.
Innovation Solution
An analyzer with a container holder, detector, controller, and display system that detects container placement, calculates the number of detection containers required, and visually notifies the user of the correct placement positions, using light sources and photodiodes to confirm container presence and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sample container is placed in a sample container holding unit without detection confirmation, then the operation is simple, but it is impossible to confirm whether the container has actually been placed in the displayed position
Solution Approach 1:
The patent implements a feedback mechanism where detectors automatically sense whether sample containers are correctly placed in the holding unit, and the control unit receives this information to display placement status to the user. This closed-loop feedback system ensures reliable container placement confirmation without requiring complex manual verification procedures.
Solution Approach 2:
The detection system operates autonomously to self-verify container placement. The detectors automatically detect container presence and position, and the control unit automatically processes this information and displays it to the user, eliminating the need for manual checking and reducing operational complexity.
2Loss of information
If the number of detection containers is not clearly indicated, then the device structure is simple, but it is difficult for users to grasp how many containers should be placed for multiple assays
Solution Approach 1:
The control unit calculates and displays the required number of detection containers before the user places them. By providing this information in advance based on the assay program, the system guides users on exactly how many containers to place, preventing information loss and improving operational ease.
Solution Approach 2:
The system provides continuous feedback to the user about container placement status and quantity. The control unit monitors how many containers have been placed versus how many are required, and displays this information to guide users in completing the setup correctly.
3Measurement precision
If manual placement of detection cells is allowed without automated detection, then the device complexity is reduced, but users cannot accurately determine container placement positions for multiple assays
Solution Approach 1:
The patent replaces manual mechanical placement verification with automated optical or electromagnetic detectors. These detectors automatically sense container presence and position without requiring manual checking, providing precise measurement of container placement status while maintaining relatively simple device architecture.
