Solution Overview

Problem

Top-bottom swimming pool cleaners oscillate vertically at the water surface, reducing their effectiveness in cleaning debris and often direct debris away due to pressure waves, necessitating improvements in stability and debris collection.

Innovation Solution

A top-bottom pool cleaner design featuring a nose with a water chamber that retains water when submerged, preventing oscillation and redirecting debris into the cleaner by using a combination of filters and a nose water chamber to maintain a stable position at the water surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the top-bottom pool cleaner reaches the water surface, then it can remove floating debris, but the cleaner oscillates vertically above and below the water surface reducing cleaning effectiveness

Engineering Contradiction:

Improvedebris removal capabilityVSAvoidvertical stability at water surface

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

The nose chamber filled with water acts as a counterweight that provides downward force to balance the upward buoyant force on the cleaner body, preventing vertical oscillation and maintaining stable positioning at the water surface for effective debris removal

Inventive Principle:

Principle #8Anti-weight (Counterweight)

2Productivity

If the pool cleaner moves through water, then it can clean wall surfaces, but pressure waves direct debris away from the cleaner

Engineering Contradiction:

Improvewall cleaning capabilityVSAvoiddebris diversion by pressure waves

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The nose chamber modifies the pressure wave pattern generated by the cleaner's movement, redirecting the pressure forces to push debris toward the cleaner's collection area rather than away from it, converting the harmful debris-diverting effect into a beneficial debris-attracting effect

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

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

The solution effectively dampens oscillation and directs debris into the cleaner, enhancing its ability to skim and collect floating debris efficiently by maintaining a stable position and utilizing pressure waves to guide debris into the collection area.

Implementation Method 1

The nose defines a chamber for receiving and retaining water within the nose. The chamber of the nose receives water through the filter when the cleaner is submerged and retains water within the chamber when the cleaner reaches a top surface of the water from under the water surface

Methodology Applied

Scientific EffectBuoyancy: Archimedes' Principle (Buoyancy)

Implementation Method 2

the retention of the water within the nose preventing the pool cleaner from oscillating above and below the top surface of the water

Methodology Applied

Scientific EffectWeight force: Gravitation

AI summary

A top-bottom pool cleaner is provided including a top housing and a nose attached to the top housing. The top housing including an exterior surface and a top surface having a filter. The nose defines a chamber for receiving and retaining water within the nose. The chamber of the nose receives water through the filter when the cleaner is submerged and retains water within the chamber when the cleaner reaches a top surface of the water from under the water surface, the retention of the water within the nose preventing the pool cleaner from oscillating above and below the top surface of the water.
