Solution Overview

Problem

Plungers used to clear clogged pipes often contaminate themselves and their storage areas with waste materials, leading to the spread of harmful bacteria and viruses like E. Coli, Salmonella, and Shigella, which can survive for extended periods and require thorough disinfection to prevent contamination.

Innovation Solution

A plunger system equipped with a disposable cover that secures over the plunger's base and handle using a fastener, allowing for easy removal and disposal after use, preventing the spread of contaminants and featuring a design that includes a plunger cup and handle with a disposable cover storage for convenient replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a plunger is used to clear clogged pipes, then the clogged pipe can be cleared, but the plunger becomes contaminated with waste materials and harmful bacteria

Engineering Contradiction:
Improveability to clear clogged pipeVSAvoidcontamination with waste materials and bacteria
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The plunger system is divided into a reusable plunger body and a disposable cover. The disposable cover is a separate component that can be easily removed and discarded after use, while the plunger body remains clean and reusable. This segmentation allows the contaminating function to be isolated to the disposable cover only.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention employs a disposable cover made from inexpensive materials that is designed to be used once and then discarded. This disposable component absorbs all contamination from the clogged pipe, eliminating the need to clean the expensive plunger body and preventing bacterial spread to storage areas.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Loss of time

If the plunger is stored without cleaning, then storage time is reduced, but contaminants spread through the storage area

Engineering Contradiction:
Improvetime for cleaning and storageVSAvoidspread of contaminants and bacteria
Core Design Contradiction:
Loss of timeVSObject-generated harmful factors

Solution Approach 1:

The contamination is extracted from the reusable plunger body and transferred entirely to the disposable cover. After use, the contaminated cover is simply removed and discarded, taking all harmful bacteria and waste materials with it. This extraction eliminates the need for cleaning the plunger body and prevents contaminant spread during storage.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system implements a discard-recover cycle where the disposable cover is discarded after single use, and the clean plunger body is recovered for reuse. This cycle eliminates the cleaning step entirely, as the reusable component never contacts contaminants, thereby preventing spread to storage areas while minimizing time loss.

Inventive Principle:
Principle #34Discarding and recovering

3Object-affected harmful factors

If a disposable cover is added to the plunger, then contamination is prevented, but device complexity increases

Engineering Contradiction:
Improvecontamination preventionVSAvoidstructure with cover and fastener
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The disposable cover is constructed from flexible, thin material that can easily conform to the plunger body shape. This simple shell structure provides effective contamination prevention without requiring complex mechanisms, maintaining ease of use while adding the necessary protective function.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The disposable cover acts as an intermediary barrier between the plunger body and the contaminated environment. This simple mediating component prevents direct contact between the reusable plunger and harmful substances, effectively reducing contamination risk while adding minimal structural complexity through a straightforward fastening mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)
