Solution Overview

Problem

Existing drain unclogging devices are either too complex and expensive for external use or ineffective and inconvenient for manual operation, limiting their accessibility and effectiveness for the average person.

Innovation Solution

A portable, hand-held piston-operated device powered by a common electric drill or screwdriver, featuring a piston moving within a cylinder with a one-way valve to create suction and pressure waves, effectively dislodging drain obstructions without the need for manual strength or complex mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If manually operated devices are used to clear drain obstructions, then the device is simple and inexpensive, but the effectiveness is limited due to human muscular strength limitations

Engineering Contradiction:

Improvedevice simplicity and costVSAvoidunclogging effectiveness

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent replaces the manual mechanical pumping system with an electric motor-driven piston system. The electric motor provides automated reciprocating motion to the piston, eliminating the need for manual operation while maintaining device simplicity. This substitution resolves the contradiction by providing machine power without the complexity of full mechanical systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The device uses the household electric drill as a self-contained power source, leveraging an existing common tool. The drill's motor directly drives the piston mechanism through a simple transmission system, creating a self-sufficient unclogging device that doesn't require separate power sources or complex mechanical assemblies.

Inventive Principle:

Principle #25Self-service

2Reliability

If externally powered devices are used to clear drain obstructions, then the effectiveness is high, but the device becomes complicated, cumbersome, or expensive

Engineering Contradiction:

Improveunclogging effectivenessVSAvoiddevice complexity and cost

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device is designed to be powered by any standard household electric drill or screwdriver, making it universally compatible with common power tools. This universality eliminates the need for specialized motors or power sources, reducing device complexity and cost while maintaining effective machine-powered unclogging capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device separates the power source (electric drill) from the unclogging mechanism (piston and cylinder assembly). This segmentation allows the use of an existing, simple power source while keeping the unclogging mechanism itself simple and inexpensive. The two components connect through a straightforward interface, avoiding the need for an integrated complex system.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If manually operated plungers are used, then the device is portable and inexpensive, but the duration and pressure of forces applied are insufficient

Engineering Contradiction:

Improveportability and affordabilityVSAvoidduration and pressure of applied forces

Core Design Contradiction:

Ease of operationVSDuration of action of moving object

Solution Approach 1:

The manual pumping action is replaced with an electric motor-driven piston that automatically provides sustained reciprocating motion. The motor maintains consistent pressure and duration of force application without fatigue, resolving the limitation of manual operation while preserving portability and simplicity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The electric motor drives the piston in continuous periodic reciprocating motion, creating alternating pressure and suction cycles. This periodic action maintains sustained effectiveness over time, overcoming the intermittent and fatigue-limited nature of manual plunger operation while keeping the device simple and portable.

Inventive Principle:

Principle #19Periodic action
