Braille Label Marker

Lack of access to information can be a significant barrier for people with visual disability, which can negatively affect their communication with others. For this reason, it seeks to develop devices that provide greater independence and autonomy for people with visual disabilities.

A label marker is a device that marks the symbol of your preference in relief, these are commonly used to mark objects and make them more attractive, but what would happen if we adapted this system with braille? Being a system that marks in relief it is perfect for making braille and the tape is perfect to place it anywhere you want.

Currently there is only one highlight braille marker on the market, but the comments are not nice and it seems to have an unattractive design, it is also a bit expensive, so we want to provide a more user-friendly marker that can really help make spaces more inclusive and friendly for people with disabilities.

The main disabilities that benefit from this project are people with visual disabilities. According to the World Health Organization, there are at least 2.2 billion people in the world with impaired near or distant vision. According to data retrieved by the Mexican Society of Ophthalmology, it is estimated that in Mexico there are more than 2.2 million people with visual disabilities and more than 415,000 with blindness, thus placing it among the top 20 countries with the largest number of people affected by visual disability.

Considerations

• It is highly recommended to use Photopolymer Resin 8K for 3D printing of the parts
• It is not recommended to resize any part.
• The tape to print can be obtained online and most of them have the same size, you just have to choose the color that you like!
• We recommend you pay special attention to the materials used because they will be very important to make it work.

The figure shows the final set and the video shows the pieces, the materials used are the following:

1. External wheel
2. Inner wheel
3. Casing base
4. Actuator
5. Tape rail
6. Torsion spring
7. Tape

Print the 3D parts from the attached documents, at this stage you will have External wheel, Inner wheel, Casing base, Actuator and Tape rail.

Don't forget to set the print file to your printer's specifications. We recommend using supports for the pieces.

Check the prints

Check that the impressions have been printed correctly, in case you have used printing supports you must remove them to leave the pieces as clean as possible

Have on hand

• Torsion spring
• Parts
• Assembly reference image

Part 1: assemble the actuator from the back of the casing base as shown in the image, applying manual pressure is enough to assemble the parts

Part 2: make sure the wheels of the actuator fit into the gap in the base casing as shown in the figure

Part 2.1: add the Torsion spring as shown in the picture

In the image 1 you can see the assembly direction, applying manual pressure.The second image is the result

Insert the tape in the direction of the image

Image 1 shows the assembly direction, there are some VERY important aspects that you should take into account:

• Be sure to position the wheels as a mirror, each tab must match its respective letter.
• The faces that come together are those that contain the braille markings, the faces without markings (of both wheels) are on the outside
• Use image 2 to visualize how the faces of the wheels should be.

Put the assembled wheels in the previous assembly, being careful that they do not move, the orientation is important, the internal wheel must go inside and the external wheel will have one face on the outside. Check image 1 and 2.

To test your marker, you must press the area shown in the image to mark each letter, each time you print a letter you must move the tape to mark the next one. Remember that you should not change the direction of the tape, otherwise it will not be able to write correctly. Enjoy!
