Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dew formation testing devices face challenges in maintaining uniform dew formation on testing samples due to inaccurate air flow control, vibration transmission from air conditioning chambers, and condensation droplets falling on the samples, leading to non-uniform condensation states.
Innovation Solution
A dew formation testing device with a separate testing tank and adjustment unit connected by ducts, featuring an air guide member that directs air flowing into the tank at a tilted angle, preventing condensation water from reaching the sample and minimizing vibration transmission, while controlling air flow velocity and angle to stabilize dew formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the outlet port of the duct is positioned right above the testing sample to directly deliver adjusted air, then the temperature of the testing sample can be made lower and dew formation can be generated, but condensation droplets generated inside the duct will fall on the testing sample causing non-uniform dew formation
Solution Approach 1:
The device is divided into separate functional components: the air conditioning chamber for generating adjusted air, the duct for air transport, and the testing chamber for dew formation testing. This segmentation allows the air outlet port to be positioned away from the testing sample, preventing condensation droplets from falling on the sample while maintaining the ability to cool the sample and generate dew formation.
Solution Approach 2:
The duct acts as an intermediary component between the air conditioning chamber and the testing chamber. By positioning the air outlet port at the end of the duct away from the testing sample, the duct mediates the delivery of adjusted air without allowing condensation droplets formed inside the duct to directly contact the testing sample, thus maintaining uniform dew formation.
2Device complexity
If the testing chamber is formed integrally with the air conditioning chamber to simplify structure, then device complexity is reduced, but vibrations of the air conditioning chamber are transmitted to the testing chamber affecting condensation state uniformity

3Device complexity
If air circulates between the testing chamber and air conditioning chamber without separate duct guidance, then device complexity is reduced, but accurate control of air flow inside the testing chamber becomes difficult resulting in non-uniform dew formation

This segmentation allows the air outlet port to be positioned away from the testing sample, preventing condensation droplets from falling on the sample while maintaining the ability to cool the sample and generate dew formation.

AI summary
A dew formation testing device 10 has an adjustment tank 12 capable of adjusting the temperature and humidity of air to predetermined temperature and humidity, a testing tank 14 installed separately from the adjustment tank 12 and having a sample base 43 that has a mounting surface 43a, onto which a testing sample W can be placed, and that is capable to cool the mounting surface 43a, and ducts 17,18 that link the adjustment unit 12 and the testing tank 14. The testing tank 14 is provided with an air guide member 57 that, when air flowing into the testing tank 14 through the duct 17 flows onto the sample base 43 from a side of the sample base 43, guides the air in the direction tilted downward at a predetermined angle, the guidance being performed at a position right above the sample base 43 at an end thereof which is on the upstream side of the air flow.
