Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a conventional solid screw is used in the screw cleansing mechanism, then the screw has sufficient structural strength, but the filtration area is reduced and weight is increased
Solution Approach 1:
The screw is divided into multiple screw blade members arranged around a central aperture, creating a segmented structure that allows water and filtration media to pass through the center while maintaining the cleansing function of the blades
Solution Approach 2:
The screw structure incorporates a central aperture that allows flow through the center, creating a porous-like effect that increases filtration area while reducing the solid material required, thus decreasing weight
2Productivity
If a conventional solid screw is used in the screw cleansing mechanism, then the screw has sufficient structural strength, but the filtration efficiency is reduced
Solution Approach 1:
The screw is divided into multiple screw blade members arranged around a central aperture, creating a segmented structure that allows water and filtration media to pass through the center while maintaining the cleansing function of the blades
Solution Approach 2:
The central aperture adds a dimensional element to the screw structure, allowing flow and filtration media passage through the center axis, effectively utilizing the three-dimensional space to enhance filtration efficiency
3Productivity
If a conventional solid screw is used in the screw cleansing mechanism, then the screw has sufficient structural strength, but the media cleansing efficiency is reduced
Solution Approach 1:
The screw is divided into multiple screw blade members arranged around a central aperture, creating a segmented structure that allows water and filtration media to pass through the center while maintaining the cleansing function of the blades
Solution Approach 2:
The central aperture enables continuous flow of water and filtration media through the center of the screw during rotation, ensuring uninterrupted contact between the media and the screw blades for continuous cleansing action
