Solution Overview

Problem

Conventional masks have poor aesthetic properties due to their design and functionality, which affects their overall appearance and user experience.

Innovation Solution

A mask frame that covers part of the mask main body and includes an attachment portion to secure it to the user's head, with optional features like a detachable cover and string fixing portion to enhance aesthetics and prevent the string from protruding.

1Shape

If a conventional mask design is used, then the mask can be easily manufactured and worn, but the aesthetic properties are poor

Engineering Contradiction:

Improveaesthetic propertiesVSAvoidmask structure complexity

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The mask is divided into separate components: a mask main body and a mask frame. The mask frame includes a frame main body that covers the end portion of the mask main body, and an attachment portion that secures the frame to the user's head. This segmentation allows the mask frame to be designed independently to improve aesthetics while maintaining the functional simplicity of the mask main body.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mask frame acts as an intermediary component between the mask main body and the user's head. It provides a structured framework that enhances the visual appearance while the attachment portion ensures secure fitting. The string fixing portion integrates the string attachment function into the frame structure, preventing the string from protruding and affecting aesthetics.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Shape

If the string is attached to the mask main body, then the mask can be secured to the head, but the string may separate and stand out, affecting aesthetic properties

Engineering Contradiction:

Improveaesthetic propertiesVSAvoidstring attachment reliability

Core Design Contradiction:

ShapeVSReliability

Solution Approach 1:

The string fixing portion integrates the string attachment function into the mask frame structure. The string is fixed to the attachment portion through the string fixing portion, which combines the securing function with the aesthetic frame design. This merging ensures the string remains reliably attached while maintaining a clean appearance without protruding elements.

Inventive Principle:

Principle #5Merging (Combining)

3Stability of the object's composition

If the mask main body is fixed to the frame main body, then the mask structure is stable, but the end portion may protrude and be exposed when attached to the head

Engineering Contradiction:

Improvemask structure stabilityVSAvoidmask contour completion

Core Design Contradiction:

Stability of the object's compositionVSShape

Solution Approach 1:

The mask main body is nested within the mask frame structure. The frame main body covers the end portion of the mask main body, creating a nested configuration where the smaller mask main body is contained within the larger frame structure. This nesting ensures the mask main body remains stable while preventing any protrusion that would compromise the mask contour and aesthetic appearance.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A mask frame for use in combination with a replaceable mask main body, includes: a frame main body that covers at least a part of an end portion of the mask main body; an attachment portion that is attached to a head of a user to hold the frame main body at a specific position with respect to the head; and a cover that is disposed at a specific position with respect to the frame main body to cover at least a part of the mask main body.
