Solution Overview

Problem

Existing mask storage solutions fail to effectively stabilize, dry, ventilate, and sterilize masks while minimizing damage and allowing easy installation and detachment of air modules, and do not provide efficient charging capabilities.

Innovation Solution

A mask storage apparatus with a body featuring a rotatable cover, compartmentalized accommodation space, a sterilization module, and an air module for forced blowing, along with a power connector for charging, which ensures the mask is kept stable, dry, and ventilated, and allows for easy installation and detachment of air components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mask is stored in a closed space, then protection from external contamination is improved, but ventilation and drying functionality deteriorates

Engineering Contradiction:
Improveprotection from contaminationVSAvoidventilation and drying
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The sterilization module performs sterilization before the mask is stored in the closed accommodation space. The air module performs drying and ventilation before closing, ensuring the mask is prepared in advance with proper hygiene and moisture control conditions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The sterilization and drying processes are designed to operate continuously or periodically while the mask is stored, maintaining hygienic conditions throughout the storage period rather than just at initial placement.

Inventive Principle:
Principle #20Continuity of useful action

2Stability of the object's composition

If the accommodation space is partitioned into multiple compartments, then organization and stability of mask storage is improved, but device complexity increases

Engineering Contradiction:
Improvemask storage stabilityVSAvoidcompartment structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The accommodation space is divided into multiple compartments using partition walls, allowing separate storage of different mask types or accessories. This segmentation organizes the storage space into functional zones while maintaining overall structural simplicity.

Inventive Principle:
Principle #1Segmentation

3Reliability

If a sterilization module is integrated into the storage apparatus, then mask sterilization effectiveness is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvesterilization effectivenessVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The sterilization module serves multiple functions: it sterilizes masks, dries them, and can potentially disinfect the accommodation space. This multi-functionality justifies the added complexity by providing comprehensive mask care in a single integrated system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Productivity

If an air module for forced blowing is added, then drying and ventilation speed is improved, but ease of installation and detachment deteriorates

Engineering Contradiction:
Improvedrying speedVSAvoidinstallation and detachment
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The air module is designed with movable or adjustable components that allow it to be easily installed and removed based on operational needs. The forced blowing function can be activated only when needed, providing dynamic control over the drying process while maintaining ease of setup.

Inventive Principle:
Principle #15Dynamics

AI summary

A mask storage apparatus includes a body including an accommodation space in which a mask device is stored. A cover is rotatably connected to the body and is capable of opening and closing the accommodation space. A compartment extends from an inner surface of the body and partitions the accommodation space into a first accommodation space in which a part of the mask device is accommodated, and a second accommodation space in which a remaining part of the mask device is accommodated. The compartment includes a sterilization module to sterilize the mask device.
