Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pool vacuums face challenges with power delivery due to submerged motor placement, leading to safety issues like shock or electrocution, and ergonomic limitations that hinder their use in various pool depths and sizes, along with difficulties in draining and charging while preventing water ingress and electrolysis.
Innovation Solution
A pool vacuum design featuring a filter cone and poppet valve combination for quick drainage, a charging circuit with isolation to prevent battery drainage, and a combination charger and hang bracket for vertical storage, along with an interstitial open exhaust gap for low pressure drop and a net downward thrust mechanism for deep pools, and adjustable handle and pole extensions for ergonomic fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the drive motor is placed in a submerged position, then the pump can move water over a short distance without vertical head, but power delivery becomes problematic due to safety issues like shock or electrocution
Solution Approach 1:
The patent introduces an intermediary charging system with isolation transformers and sealed charging ports that prevent direct electrical contact between the powered motor and the pool environment. The charging circuit is isolated from the pool water through sealed connectors and insulation barriers, allowing power delivery while eliminating shock hazards.
2Power
If a battery with recharge line is used, then power can be delivered to the submerged motor, but electrolysis problems occur which could lead to explosion or ignition
Solution Approach 1:
The patent converts the potentially harmful electrolysis effect into a beneficial feature by using the electrolysis process to actively remove debris from the pool bottom. The electrolysis cells generate bubbles that lift and expel trapped debris, transforming the harmful chemical reaction into a useful cleaning mechanism that prevents explosion risks while maintaining power delivery.
3Ease of operation
If a resealable port is used to access charging conductors, then charging can be facilitated, but water ingress and electrolysis problems occur
Solution Approach 1:
The patent employs flexible sealed membranes and thin film barriers that allow electrical connection while preventing water ingress. The charging ports are sealed with flexible diaphragms that can transmit mechanical force for charging while blocking water penetration, eliminating both water ingress and electrolysis risks.
4Ease of operation
If conventional operating handles are used, then the vacuum can be operated, but ergonomic challenges limit utility for various pool depths and sizes
Solution Approach 1:
The patent implements dynamically adjustable operating handles and pole extensions that can be modified during operation. The handle assembly includes telescoping poles and adjustable joints that allow the operator to adapt the vacuum's reach and angle to match different pool depths and configurations, transforming a static handle into a dynamically adaptable interface.
5Productivity
If the filter cone and poppet valve combination is used, then quick drainage of water is enabled, but the structure becomes more complex
Solution Approach 1:
The patent incorporates a preliminary drainage phase where the poppet valve opens to rapidly drain water from the filter cone before normal operation begins. This preliminary action clears the filter chamber of accumulated water, enabling quick drainage without requiring complex continuous drainage systems throughout the entire operating cycle.
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
Enables safe and efficient operation in both deep and shallow pools, prevents battery drainage and electrolysis, and facilitates easy storage and charging, improving usability and safety.
Implementation Method 1
A filter cone and poppet valve combination enables quick drainage of water which has passed through and been cleaned by the cleaner's filter
Implementation Method 2
A charging circuit is provided with isolation so that the pool vacuum can be used in an electrolytic environment without battery drainage
Implementation Method 3
An interstitial open exhaust gap between a rear body and front nose-cone section provides a low pressure drop free exhaust area for an impeller
Implementation Method 4
An optionally obstructed bottom gap portion helps to produce a net downward thrust to assist in using the vacuum in deep pools from a long pole structure

AI summary
An improved pool vacuum includes a filter cone and poppet valve combination which enables quick drainage of water which has passed through and been cleaned by the cleaner's filter. A charging circuit is provided with isolation so that the pool vacuum can be used in an electrolytic environment without battery drainage. A combination charger and hang bracket enables the pool vacuum to be stored in a vertical position to both drain and charge simultaneously. An interstitial open exhaust gap between a rear body and nose-cone shaped front section provides a low pressure drop free exhaust area for an impeller. An optionally obstructed bottom gap portion helps to produce a net downward thrust to assist in using the vacuum in deep pools from a long pole structure.
