Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If oppositely arranged air ports are provided in the air column, then airflow convection is enhanced, but oil enters the air column through these ports causing trigger failure
Solution Approach 1:
The patent removes one of the two oppositely arranged air ports from the air column, extracting the harmful pathway that allows oil to enter. By keeping only a single air port, the design eliminates the convection current that draws oil into the trigger mechanism while preserving sufficient airflow for proper trigger operation.
Solution Approach 2:
The air column structure is segmented into functional zones: the remaining single air port provides controlled airflow entry, the oil-resistant cavity isolates the trigger mechanism from oil exposure, and the atomization component separates the liquid reservoir from the trigger assembly. This segmentation prevents oil migration while maintaining airflow functionality.
2Reliability
If a single air port is provided in the air column, then oil entry is prevented, but airflow convection is reduced
Solution Approach 1:
The oil-resistant cavity acts as an intermediary structure between the air port and the trigger mechanism. It mediates the airflow by allowing convective air movement through the single air port while physically blocking oil from reaching the trigger, thus decoupling the airflow function from the oil-exposure risk.
Solution Approach 2:
The harmful function of oil entry is extracted and isolated into a dedicated oil-resistant cavity that is sealed off from the trigger mechanism. This allows the air port to fulfill its airflow purpose without the harmful side effect of oil contamination, as the cavity captures and contains any potential oil exposure.
3Volume of moving object
If the air column is positioned close to the atomization component, then device compactness is improved, but oil easily enters the air column
Solution Approach 1:
The oil-resistant cavity serves as a protective intermediary between the air column and the atomization component. It creates a sealed barrier that allows the air column to be positioned close to the atomization component for compactness while preventing oil from the atomization area from reaching the air column and trigger mechanism.
Solution Approach 2:
The oil-resistant cavity is formed using flexible sealing structures and thin film barriers that effectively block oil migration. These sealing elements create a protective envelope around the trigger mechanism, allowing close proximity to the atomization component while maintaining oil resistance through the flexible barrier properties of the cavity structure.
