Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Coolers often develop mold, mildew, and unwanted odors due to residual moisture, which can lead to an unclean and unusable state when closed before drying.

Innovation Solution

A pouch containing a silica desiccant and sodium bicarbonate core layer, surrounded by a liquid-resistant vapor barrier material, combined with super absorbent polymer layers within liquid-permeable fabrics, is placed inside the cooler to absorb moisture and odors, preventing mold and musty smells.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cooler is closed before the interior is fully dried, then the cooler can be stored or transported, but mold, mildew, and unwanted odors develop

Engineering Contradiction:

Improvecleanliness of coolerVSAvoidmold and mildew growth

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The desiccant and deodorizer are placed in the cooler before closing to perform drying and deodorizing actions in advance, preventing mold and mildew growth that would occur if the cooler were closed before fully dried

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The desiccant and deodorizer act as intermediary substances between the moisture/odors in the cooler and the environment, absorbing and neutralizing harmful factors to prevent mold and mildew development

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If cleaning is performed thoroughly, then the cooler is free of contaminants, but residual moisture remains on interior walls

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidresidual moisture

Core Design Contradiction:

Ease of manufactureVSQuantity of substance

Solution Approach 1:

The desiccant extracts and removes residual moisture from the cooler interior after cleaning, separating the moisture removal function from the cleaning process itself

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical cleaning process is supplemented by chemical absorption using desiccant materials, replacing the need for mechanical drying methods

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
