Solution Overview

Problem

Existing swimming pool vacuum systems are either expensive, bulky, time-consuming, or pose electrocution risks due to limited battery life, large and heavy hoses, or inadequate suction power, and lack protection against electric shock.

Innovation Solution

A self-contained, portable swimming pool vacuum with a direct current underwater pump, 120 volt AC to 24 volt DC converter, filter, and underwater low voltage cord, attached to a universal pool telescoping pole, providing 40-65 gpm suction power and electrical protection against electrocution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If hand-held battery operated vacuum devices are used, then portability is improved, but battery life is limited and requires frequent recharging

Engineering Contradiction:

ImproveportabilityVSAvoidbattery life

Core Design Contradiction:

Ease of operationVSDuration of action of moving object

Solution Approach 1:

The battery component is extracted and removed from the system entirely. The vacuum device uses an external power source (outlet) instead of an internal battery, eliminating the need for recharging while maintaining portability through the telescoping pole design.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The vacuum device is designed to work with standard electrical outlets, making it universally compatible and eliminating battery limitations. The same device can be used indefinitely as long as electrical power is available, rather than being constrained by battery capacity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If in-floor cleaning systems are installed, then cleaning effectiveness is improved, but installation cost and complexity increase significantly

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidinstallation cost

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The cleaning system is segmented into a portable handheld unit that can be used independently without requiring installation of fixed infrastructure like in-floor systems. The telescoping pole and vacuum head can be assembled and disassembled as needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system requires no professional installation or modification of the pool structure. The user can simply assemble the telescoping pole, attach the vacuum head, and begin cleaning without requiring contractors or structural changes to the pool.

Inventive Principle:

Principle #25Self-service

3Extent of automation

If robotic automatic pool cleaners are used, then automation is improved, but device size and weight increase

Engineering Contradiction:

ImproveautomationVSAvoiddevice weight

Core Design Contradiction:

Extent of automationVSWeight of moving object

Solution Approach 1:

The telescoping pole acts as an intermediary that provides structural support and positioning for the vacuum head, allowing the device to be lightweight yet maintainable during operation. The pole bears the weight rather than the vacuum head itself.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Productivity

If standard vacuum hoses are used with pool equipment, then debris removal is improved, but hose length and storage requirements increase

Engineering Contradiction:

Improvedebris removalVSAvoidhose length

Core Design Contradiction:

ProductivityVSLength of stationary object

Solution Approach 1:

The telescoping pole is dynamic and adjustable in length, allowing the user to optimize the reach for different pool sizes and configurations. The pole can be extended or retracted as needed, providing flexibility without requiring excessive length.

Inventive Principle:

Principle #15Dynamics

5Ease of operation

If equipment is assembled and disassembled for each use, then portability is improved, but setup time increases

Engineering Contradiction:

ImproveportabilityVSAvoidsetup time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The device is segmented into modular components (telescoping pole sections, vacuum head, filter) that can be quickly assembled and disassembled. Each section connects through simple interfaces that require minimal tools or effort to join and separate.

Inventive Principle:

Principle #1Segmentation

AI summary

A liquid-submersible vacuum system includes a housing canister enclosing a filtration element and a water pump. Power comes from a power converter that plugs into a standard AC power supply. The vacuum system further includes a diffuser cap and a discharge hose cap, with each providing the vacuum system with a discrete mode of operation.
