Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealed chamber with low temperature is used to generate condensing layer, then the condensing layer can be formed on the object surface, but the process becomes difficult to automate and requires costly equipment
Solution Approach 1:
The patent extracts the condensing chamber from the sealed chamber environment, allowing the test object to remain in a normal environment while only the airflow is controlled to achieve condensation. This eliminates the need for complex sealed chambers and low-temperature environments, making the system easier to automate and more cost-effective.
Solution Approach 2:
The patent introduces controlled condensing airflow as an intermediary medium to transfer moisture to the test object surface. Instead of cooling the entire chamber, the system uses a separate airflow generation device to deliver precisely controlled humid air that condenses on the heated object surface, simplifying the overall system architecture.
2Reliability
If a sealed chamber with low temperature is used to generate condensing layer, then the condensing layer can be formed on the object surface, but the process takes a lot of time to generate the low temperature environment
Solution Approach 1:
The system pre-heats the test object to a temperature above the dew point before introducing the condensing airflow. This preliminary heating ensures that when the humid air contacts the object surface, condensation occurs immediately without requiring time-consuming cooling of the entire chamber environment.
Solution Approach 2:
The patent replaces the mechanical thermal system (cooling the entire chamber) with a fluid control system (delivering controlled condensing airflow). Instead of using large-scale thermal mass to cool the environment, the system uses precisely controlled airflow with specific temperature and humidity parameters to achieve condensation rapidly on the object surface.
3Reliability
If a sealed chamber is manufactured to generate condensing layer, then the condensing layer can be formed, but the manufacturing cost is high
Solution Approach 1:
The patent divides the system into separate functional modules: a normal environment test object holder, a separate airflow generation device, and a condensing chamber that only needs to contain the airflow path. This segmentation eliminates the need for expensive sealed chambers, as each component can be manufactured independently using simpler, more cost-effective methods.
4Reliability
If the object enters and exits the sealing chamber to generate condensing layer, then the condensing layer can be formed, but the process cannot be easily automated
Solution Approach 1:
The patent extracts the test object from the sealed chamber environment, allowing it to remain stationary in a normal environment while the condensing airflow is delivered to it. This eliminates the need for mechanical systems to move objects in and out of chambers, enabling easy automation through programmable airflow control and heating.
