Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the filter piece is placed between the liquid percolation piece and locking members to absorb cigarette liquid, then the liquid absorption function is improved, but the filter piece becomes soft and deformed causing leakage
Solution Approach 1:
The pressing plate serves as an intermediary component between the locking members and the filter piece. It transmits the locking force to the filter piece while preventing direct contact that would cause deformation, thus maintaining both absorption capacity and structural stability.
Solution Approach 2:
The pressing plate applies localized pressure specifically to the edges and critical support areas of the filter piece, rather than uniform compression. This localized quality of pressure maintains the filter piece's absorption properties in the central area while preventing deformation at vulnerable points.
2Productivity
If the filter piece is allowed to become soft after absorbing liquid, then the liquid absorption efficiency is improved, but the filter piece separates from the liquid percolation piece
Solution Approach 1:
The locking members are pre-installed on the liquid storage cup before the filter piece is placed. This preliminary action ensures that the structural framework is ready to secure the filter piece once it absorbs liquid and becomes soft, preventing separation while maintaining absorption efficiency.
Solution Approach 2:
The pressing plate acts as a mediator that maintains the connection between the softened filter piece and the liquid percolation piece. It distributes the mechanical stress and prevents direct separation even when the filter piece loses structural rigidity after absorption.
3Reliability
If the filter piece is tightly secured to prevent deformation, then the leakage problem is solved, but the liquid percolation efficiency may be reduced
Solution Approach 1:
The pressing plate applies pressure selectively to specific areas of the filter piece (edges and support zones) rather than the entire surface. This localized constraint prevents leakage and deformation while leaving the central percolation areas sufficiently open to maintain liquid flow efficiency.
Solution Approach 2:
The locking mechanism provides sufficient (but not excessive) pressure through the pressing plate to prevent leakage. The pressure is calibrated to be just enough to secure the filter piece without over-compression that would block liquid percolation, achieving the optimal balance between reliability and productivity.
