Detection Device Transparent Area Mist Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collection and detection devices face challenges in accurately reading test results due to external and internal environmental factors, such as mist formation, which obstructs the visibility of the detection area, leading to inaccurate readings.
Innovation Solution
The device incorporates a transparent area and a detection area with a blocking element that reduces fluid exchange between the detection area and the surrounding environment, ensuring the detection area remains clear by either attaching to the inner wall of the collecting chamber or filling the gap between them, thereby preventing mist formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the detection area is made transparent for reading test results, then the visibility of test results is improved, but mist formation on the transparent surface obstructs the reading accuracy
Solution Approach 1:
The device is divided into separate functional areas: a transparent area for reading test results and a detection area for the actual detection process. The transparent area allows optical reading while the detection area handles sample interaction, separating the reading function from the detection function to prevent mist interference.
Solution Approach 2:
The transparent area is extracted as a distinct component from the detection area. By separating the transparent reading surface from the detection zone where samples are processed, the patent eliminates the source of mist formation from the reading path, allowing clear visibility without obstruction.
2Adaptability or versatility
If the detection area is exposed to the surrounding environment for sample interaction, then the detection function is improved, but fluid exchange causes mist formation that blocks visibility
Solution Approach 1:
The device structure segments the detection area from the surrounding environment using a blocking element. This allows the detection area to interact with samples while being isolated from environmental factors that cause mist formation, maintaining detection functionality without harmful condensation.
Solution Approach 2:
A blocking element acts as an intermediary between the detection area and the surrounding environment. This element permits necessary sample interaction while preventing harmful fluid exchange and mist formation, serving as a selective barrier that maintains both detection capability and visibility.
3Measurement precision
If a blocking element is added to prevent fluid exchange, then mist formation is reduced, but the device structure becomes more complex
Solution Approach 1:
The blocking element is merged with the existing structure of the detection device, integrating the mist-prevention function into the overall device architecture. This combination approach adds minimal structural complexity while achieving the desired clarity improvement.
Solution Approach 2:
The blocking element serves multiple functions: it prevents fluid exchange to reduce mist formation, maintains structural integrity of the device, and supports the separation between detection and transparent areas. This multi-functionality reduces the need for additional separate components.
