Pool Cleaner Cleaning Structure with Flexible Bristles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing submersible automated pool cleaning vehicles (PCVs) struggle to thoroughly clean pool surfaces, particularly in dislodging and removing embedded dirt and debris, leading to potential pH imbalance and unstable pool water conditions, necessitating frequent and costly pool draining.
Innovation Solution
A cleaning structure attachable to the PCV, featuring bristles or fingers extending from the drive members, which contact the pool surface to dislodge dirt and debris, allowing the vehicle to suck up the dislodged material, utilizing a force fit connection with the track to withstand obstacles and provide flexible yet durable cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard PCV without additional cleaning structure is used, then the device complexity is low, but the cleaning effectiveness is insufficient to remove embedded dirt and debris
Solution Approach 1:
The cleaning structure is divided into multiple cleaning elements (bristles, fingers, or pads) that can be individually attached to the track. Each element independently contacts the pool surface to dislodge dirt and debris, allowing the system to effectively clean without requiring a completely redesigned complex vehicle
Solution Approach 2:
The cleaning elements serve as intermediary components between the PCV track and the pool surface. These elements transfer the mechanical motion of the track into effective cleaning action by contacting and dislodging embedded particulates, enabling the PCV to clean effectively without major structural modifications
2Adaptability or versatility
If the cleaning structure uses a rigid connection to the track, then the strength and durability are high, but the ability to adapt to obstacles and pool surfaces is reduced
Solution Approach 1:
The cleaning elements are designed with dynamic attachment mechanisms that allow them to move and adjust relative to the track. This dynamic connection enables the cleaning elements to adapt to various pool surfaces and obstacles while maintaining sufficient connection strength through force-fit or friction-fit interfaces
Solution Approach 2:
The cleaning elements can be made from flexible materials that allow them to conform to the pool surface and obstacles. This flexibility enables adaptation to irregular surfaces while the force-fit connection to the track maintains structural integrity and connection strength
3Productivity
If the PCV operates without a cleaning structure, then the ease of operation is high, but the productivity in terms of cleaning thoroughness is low
Solution Approach 1:
The cleaning elements serve multiple functions: they clean the pool surface, protect the track from damage, and can be easily attached or removed. This multi-functionality increases cleaning thoroughness while maintaining ease of operation, as the elements are designed for simple installation and can be replaced if needed
