Electrically powered pool vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrically powered pool cleaners face challenges in efficiently removing debris from the bottom and surfaces of pools, particularly in tight spaces and at varying depths, due to limitations in design and operation modes.
Innovation Solution
The electrically powered pool cleaner features a housing with a rotatable sleeve impeller and motor, a filter bag system, and a rigid cover with a handle for handheld operation, allowing for accelerated fluid flow and debris collection while enabling multiple operation modes, including submersion, handheld use, and surface skimming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pool cleaner uses a motor and impeller to create suction, then debris removal capability is improved, but the device complexity increases
Solution Approach 1:
The patent combines the motor, impeller, and collection bag into a single integrated vacuum unit that can be manually positioned. This merging of components into one cohesive device provides effective debris removal while avoiding the complexity of multiple separate systems working together.
Solution Approach 2:
The vacuum unit is designed to perform multiple functions: it can clean the bottom surfaces of pools, reach into tight spaces, and operate at varying depths. The single device serves as both a bottom cleaner and a surface skimmer, eliminating the need for separate equipment for different cleaning tasks.
2Reliability
If the pool cleaner is designed for bottom cleaning only, then cleaning effectiveness on pool surfaces is improved, but adaptability to different operation modes deteriorates
Solution Approach 1:
The vacuum unit is specifically designed to be multi-functional, capable of operating in at least three distinct modes: bottom cleaning mode where the unit rests on the pool floor, handheld mode for reaching tight spaces and higher surfaces, and surface skimming mode for removing debris from the water surface. This universal design allows a single device to replace multiple specialized cleaners.
Solution Approach 2:
The pool cleaner is designed with dynamic positioning capability, allowing it to transition between different operational states. The unit can be placed on the bottom, held in the hand, or positioned at the surface, with the impeller and collection bag orientation adapting to each mode to maintain cleaning effectiveness.
3Stability of the object's composition
If the filter bag is permanently attached to the housing, then structural stability is improved, but ease of maintenance and debris disposal deteriorates
Solution Approach 1:
The collection bag is designed as a separate, removable component that can be detached from the housing. This segmentation allows the bag to be easily removed for emptying or replacement without disassembling the entire vacuum unit, maintaining structural integrity during operation while enabling simple maintenance.
Solution Approach 2:
The filter bag is designed to be removable and replaceable, allowing users to easily discard full bags and install fresh ones. This design facilitates regular maintenance and debris disposal without requiring complex disassembly procedures, balancing structural stability with operational convenience.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances debris removal efficiency across different pool surfaces and areas, including tight spaces and higher surfaces, by ensuring continuous debris collection and filtered water return, offering versatility and ease of use.
Implementation Method 1
A motor may be operatively connected to the sleeve impeller and a power supply operatively connected to the motor. Rotation of the sleeve impeller may accelerate fluid flow through the axial passageway for drawing into the filter bag.

AI summary
An electrically powered pool cleaner may include a housing defining an axial passageway. A rotatable sleeve impeller may be supported by the housing within the axial passageway. The axial passageway may include an unobstructed central portion for passage of fluid and pool debris therethrough into a filter bag removably connected to the housing. A motor may be operatively connected to the sleeve impeller and a power supply operatively connected to the motor. Rotation of the sleeve impeller may accelerate fluid flow through the axial passageway for drawing into the filter bag. The pool cleaner may include a rigid cover enclosing the filter components. The rigid cover may include a handle for handheld operation of the pool cleaner.
