Pool Robot Dual Drain Layout for Stable Steering and Fine Debris Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current swimming pool robots face issues with movement direction stability due to single drain pipe alignment, and dust bags with low density allow small debris to leak while high-density bags affect water flow, impacting cleaning efficiency and direction control.
Innovation Solution
A swimming pool robot with double drain pipes and a dual-filter system, equipped with sensing devices and climbing mechanisms, allows for precise direction control and efficient debris collection by using symmetrically arranged drain outlets and filters with varying densities to accommodate different debris sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single drain pipe is provided along the central line, then the robot structure is simple, but the movement direction stability deteriorates when the robot body deviates from the central line
Solution Approach 1:
The single central drain pipe is segmented into two separate drain pipes positioned at different locations. This segmentation allows independent control of water flow from each pipe, enabling the robot to maintain stable movement direction even when the body deviates from the central line by adjusting the flow distribution between the two pipes.
Solution Approach 2:
The two drain pipes are positioned asymmetrically relative to the robot's central line, allowing differential water flow control. By adjusting the flow rate from each pipe independently, the robot can generate corrective forces to maintain directional stability without requiring perfect central alignment.
2Quantity of substance
If a low density dust bag is used, then large volume trash like leaves can be accommodated, but small volume trash like sand leaks through
Solution Approach 1:
A dual-layer dust bag system is implemented where an inner dust bag with high density material is nested within an outer dust bag with low density material. The inner bag captures small volume debris like sand, while the outer bag accommodates large volume trash like leaves, ensuring both types of debris are collected effectively without leakage.
Solution Approach 2:
The dust bag system uses composite material construction with two different density materials. The high density inner material provides effective filtration for small particles, while the low density outer material provides capacity for bulk debris, creating a composite system that overcomes the limitations of single-material dust bags.
3Reliability
If a high density dust bag is used, then small volume trash can be accommodated well, but the dust bag affects water flow and reduces reaction force
Solution Approach 1:
The nested dual-layer dust bag structure allows the high density inner bag to collect small debris while the low density outer bag maintains larger clearance for water flow. This nested arrangement minimizes the overall impact on water flow and reaction force while preserving effective small debris collection.
Solution Approach 2:
Different density materials are applied locally to different functional requirements: high density material in the inner bag where debris collection is critical, and low density material in the outer bag where water flow passage is more important. This local differentiation optimizes both debris collection and movement performance.
