Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrophoresis devices struggle to visually detect and specify foreign matter such as air bubbles and dust in the pump flow path, leading to difficulties in identifying the cause of abnormalities and potentially causing damage to components.
Innovation Solution
An electrophoresis device equipped with a photographing device and a control unit that analyzes images of the flow path to detect the presence or absence of foreign matter, allowing for automatic detection and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current value detection is used to detect abnormalities in the pump flow path, then abnormality detection capability is improved, but the ability to visually confirm and specify foreign matter is worsened
Solution Approach 1:
The patent combines two detection methods: current value detection (electrical measurement) and image capture (visual detection). The control unit integrates both detection results to comprehensively identify foreign matter. This merging allows the system to leverage the sensitivity of current detection while adding the visual confirmation capability of imaging, thereby resolving the contradiction between abnormality detection capability and visual confirmation difficulty.
Solution Approach 2:
The control unit acts as an intermediary that processes and correlates data from both the current detection circuit and the image capture device. It combines the electrical measurement information with visual image information to produce a comprehensive diagnosis of foreign matter presence and characteristics, enabling both automated detection and visual specification.
2Loss of information
If visual inspection of the pump flow path is performed to specify foreign matter, then cause identification is improved, but detection accuracy is worsened due to difficulty in seeing air bubbles and foreign matter
Solution Approach 1:
The patent merges the advantages of both current detection (high sensitivity to foreign matter presence) and image capture (visual specification capability). The control unit correlates the precise location information from images with the abnormality detection from current measurements, enabling accurate cause identification while maintaining high detection accuracy through the complementary strengths of both methods.
