Solution Overview

Problem

Clogged pipes often require lengthy and messy procedures to unclog, as wastewater flows uncontrollably when access points are opened, making it difficult to locate and clear blockages efficiently.

Innovation Solution

A pipe unclogging device with a main body, branch portion, and a rotatable cover that can obstruct or allow fluid flow, combined with a plunger device to manage fluid pressure and locate blockages, preventing backflow and allowing for efficient clearing of clogs without wasting water.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If access points are opened to unclog pipes, then blockages can be cleared, but wastewater flows uncontrollably and cleanup time increases

Engineering Contradiction:
Improveunclogging efficiencyVSAvoidcleanup time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The device segments the pipe system by introducing a portable unclogging unit that can be inserted into specific sections of the pipe. This allows targeted unclogging at the blockage location rather than requiring access to the entire pipe system, thereby containing wastewater and reducing cleanup time while maintaining unclogging efficiency

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The portable pipe unclogging device acts as an intermediary tool that can be inserted through existing pipe infrastructure. It provides a controlled interface for unclogging operations, containing wastewater within the pipe system during the process and eliminating the need for extensive cleanup while maintaining effective blockage clearance

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If unclogging starts from the beginning of the pipe, then blockages can be reached, but very long snakes are required and time increases

Engineering Contradiction:
Improveunclogging speedVSAvoidsnake length
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The device enables preliminary positioning at or near the blockage location before unclogging operations begin. By allowing the unclogging tool to be inserted directly to the problem area through the portable unit rather than from the pipe beginning, it eliminates the need for very long snakes and reduces the time required to reach and clear blockages

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the cover is in the first position, then backflow is prevented, but fluid flow is obstructed

Engineering Contradiction:
Improvebackflow preventionVSAvoidfluid flow
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The cover is designed to be rotatable between different positions, allowing dynamic adjustment of its function. When in the first position, it prevents backflow; when rotated to the second position, it allows unobstructed fluid flow. This dynamic repositioning enables the same component to serve multiple functions depending on operational needs

Inventive Principle:
Principle #15Dynamics

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

AI summary

A pipe unclogging device and system are disclosed. The device allows a user to clear a blockage in a pipe downstream from the start of the pipe system quickly and easily. To do so, the device provides a pipe with a branch portion, with a plunger device operably coupled to the branch portion. In use, the plunger device is actuatable to plunge fluid in the pipe, or it can be removed to provide a user direct access to the pipe system for other unclogging tools, such as a plumbing snake.
