Fog Free

Mask Brace

By Wizards@Work

introduction

• COVID-19 outbreak has become an eye-opener for the world.

​

• The situation has made wearing a mask mandatory lifestyle for us.

​

• This has surfaced some unanswered problems and we are providing a solution to one of the most viral COVID-19 consequences.

The Problem

01

Do you wear spectacles?

Did you face any problems?

​

The problem

​

Wearing a face mask together with spectacles makes your spectacles get foggy. This has been a problem for some communities from a long time, but for majority of the public this was a consequence of COVID-19 pandemic.

Now, this has become an everyday struggle for spectacle wearers when a face mask is worn with their spectacles.

The problem

• Wearing a face mask together with spectacles makes your spectacles get foggy.�
• For majority of the public this was a consequence of COVID-19 pandemic.�
• Now, this has become an everyday struggle for spectacle wearers when a face mask is worn with their spectacles.

​

​

Why do glasses fog?

​

• When hot air falls on a cool surface, the air �particles condense and form small water droplets. �
• Simply put, this is called fog. �
• The same thing happens when you wear glasses with a face mask. As your warm exhaled air exits from the top unsealed gaps of the mask, they tend to form fog on your glasses.

​

​

But Is this a real problem?

• To validate the design idea from the consumer’s perspective we conducted a small survey before initiating the design process.�
• The followings are some responses collected from the survey.

Design Requirements

​

​

• Affordability

​

• Cost

​

• Comfortability

​

​

Criterias

• Simplicity

​

• Protection

​

• No side effects (allergies)

​

Constraints

• Re-usability

​

Conceptual Design Idea

• The main reason behind the identified problem is the condensation of the exhaled air on the glasses.�
• The easiest way to prevent this phenomenon was to seal those gaps between the nose area and the mask.�
• The Mask Brace was the best approach to solve the problem.

​

What is a mask brace?

​

​

• A Mask Brace can be used to provide a better mask fit.�
• This helps your face masks to fit more tightly on the face.

Why is a mask brace more suitable over other fog-free products

• 100% fog-freeness

​

• Re-usability

​

• Compatible with all most all the face-masks available in the market

​

• Easy to handle

​

• Comparatively high affordability

​

• Stretchable and flexible

​

• Safer than using fog-free chemicals

This is the conceptual design we came up with

​

Design Solution

• The people who use spectacles face the daily struggle of foggy glasses which blocks the vision of the user.

​

• The aim was to create a device to reduce the gaps between the face and the mask.

​

• A Mask Brace suited the most as the solution and liquid silicone rubber is planned to use as the basic raw material for MB 1.0.

Why silicone rubber?

• Excellent insulation properties.

​

• Low bio and chemical reactivity and toxicity because it’s a natural material.

​

• Because of its low glass transition temperature (Tg), it is flexible at room temperature.

​

• More durable than other materials because of high mechanical properties and thermal properties such as heat capacity and high tensile strength.

​

Feasibility

Current International Market

• Fog free mask ⇒ 3000-12000 LKR�
• Fog free sprays(50g) ⇒ 3000 LKR�
• Shipping cost from overseas ⇒ 300-500 LKR

`

MB 1.0

• Cost for raw material for one unit will 50 - 70 LKR�
• Local companies confirm that one unit will cost about 90 LKR for manufacturing.�
• Price in market will be only 200-250 LKR

Our Design for MB 1.0

design that has a non-flexible nose shape to fit the nose without any gaps and a flexible outer design to make breathing more comfortable.
