Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the filter device is arranged inside the body with conventional hydraulic circuit configuration, then the filtration function is achieved, but the water weight increases and extraction becomes difficult
Solution Approach 1:
The filter device is segmented from the main body through a removable cover on the lateral face, allowing the filter basket to be separated and extracted independently. This segmentation enables the filter to be removed without extracting the entire cleaning robot from the pool, reducing the water weight that must be moved and facilitating easier maintenance.
Solution Approach 2:
The filter basket is extracted from the conventional internal arrangement where it must be removed by turning over the entire robot. Instead, the filter basket is taken out through a lateral access opening, allowing users to remove and clean the filter while the robot remains in the pool, significantly reducing the operational burden and water handling requirements.
2Productivity
If the filter device is arranged inside the body with conventional hydraulic circuit configuration, then the filtration function is achieved, but the swirling movements are prevented and filtration efficiency decreases
Solution Approach 1:
The filter basket is designed with a cylindrical shape and the hydraulic circuit is configured to direct water flow along the curved lateral walls of the cylinder. This curvature enables the water to follow a natural swirling path without being blocked by straight walls, generating cyclonic movements that enhance filtration efficiency through centrifugal separation of debris.
Solution Approach 2:
The hydraulic circuit is designed to change the flow parameters by directing water to enter the filter basket in a specific manner that generates rotational flow. The circuit configuration transforms the linear pump output into swirling motion, changing the flow velocity distribution and creating the cyclonic effect necessary for efficient filtration without requiring additional mechanical moving parts.
3Ease of operation
If the filter device is accessed via upper wall hatch, then the filter can be removed, but the user must handle debris and sludge causing discomfort
Solution Approach 1:
The filter basket is extracted from the conventional arrangement where it must be removed by turning over the entire robot. Instead, the filter basket is taken out through a lateral access opening, allowing users to remove and clean the filter while the robot remains in the pool, significantly reducing the operational burden and water handling requirements.
Solution Approach 2:
The lateral access design allows the filter basket to be easily removed and cleaned by the user without requiring the robot to be taken out of the pool or inverted. The simplified access mechanism enables quick filter maintenance with minimal exposure to debris and sludge, making the cleaning process safer and more convenient for the user.
