Solution Overview

Problem

Conventional swimming pool cleaners have a limited suction cleaning path width, which increases cleaning time but widening them compromises maneuverability and requires more power, making them heavier and harder to handle.

Innovation Solution

The introduction of side intake flaps that diverge outward from the housing, angled to funnel water and debris under them, increasing the cleaning path width without sacrificing suction power, using a lightweight yet sturdy material like PVC and a rotating wheel to maintain clearance above the pool floor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the width of the pool cleaner is increased to increase the suction cleaning path, then the cleaning efficiency is improved, but the maneuverability and ability to clean indentations/bends/transitional areas is reduced

Engineering Contradiction:
Improvesuction cleaning path widthVSAvoidmaneuverability
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The cleaning device is segmented into a main housing body and detachable side intake flaps. The flaps can be independently attached or removed, allowing the cleaning path width to be adjusted without changing the entire device structure. This segmentation enables the device to maintain a compact core size for maneuverability while expanding the cleaning path when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The side intake flaps are designed to be adjustable and reconfigurable rather than fixed. The flaps can be positioned at different angles and orientations to adapt to various pool geometries, including straight sections, bends, and transitional areas. This dynamic adjustability allows the device to optimize its cleaning path width for different cleaning scenarios while maintaining maneuverability.

2Productivity

If the width of the pool cleaner is increased to increase the suction cleaning path, then the cleaning efficiency is improved, but the weight of the pool cleaner increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The cleaning device is segmented into a main housing body and detachable side intake flaps. The flaps can be independently attached or removed, allowing the cleaning path width to be adjusted without changing the entire device structure. This segmentation enables the device to maintain a compact core size for maneuverability while expanding the cleaning path when needed.

Inventive Principle:

Solution Approach 2:

The side intake flaps are constructed from lightweight yet durable materials that provide structural integrity while minimizing weight addition. The flaps use thin-walled constructions and flexible connections that allow them to be easily attached and removed without significantly increasing the overall weight of the cleaning device.

Inventive Principle:
Principle #30Flexible shells and thin films

3Productivity

If the width of the pool cleaner is increased to increase the suction cleaning path, then the cleaning efficiency is improved, but more power/suction is required to move the drive members

Engineering Contradiction:
Improvesuction cleaning path widthVSAvoidpower/suction requirement
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The side intake flaps are designed to be adjustable and reconfigurable rather than fixed. The flaps can be positioned at different angles and orientations to adapt to various pool geometries, including straight sections, bends, and transitional areas. This dynamic adjustability allows the device to optimize its cleaning path width for different cleaning scenarios while maintaining maneuverability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device allows for changing the effective cleaning width parameter by attaching or removing side intake flaps, rather than permanently increasing the device width. This parameter change enables the cleaning path width to be optimized for specific cleaning needs without permanently increasing drag and power requirements. The flaps are designed to minimize hydrodynamic resistance while maximizing cleaning efficiency.

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

Enhances cleaning efficiency by widening the suction path without reducing suction power, allowing for balanced flow and easier navigation of pool cleaners through indentations and bends.

Implementation Method 1

the flap diverges outward from the slot and is fan shaped... the interior of the flap is angled downward so that a distance above a bottom surface of the flap decreases as the flap extends outward away from the housing

Methodology Applied
Scientific EffectFluid flow:

Implementation Method 2

A wheel is coupled to the flap. The wheel keeps a bottom surface of the flap a minimum distance above a floor/wall of a swimming pool

Methodology Applied
Scientific EffectMechanical support:

Implementation Method 3

The drive member may also be used to create at least a partial vacuum so that water will be encourage to enter one or more intake ports formed in the housing
