Some friends hoped that I could upload the more detailed description and design process of the barrier-free braille board, so I had to upload the typesetting and effect diagram of the very slag at that time with a thick face. There was the working principle of the braille board and the introduction of the first edition of the braille board. If I don't know the barrier-free braille board, just look at my other original article. The pictures are many and smelly. Please

This is the result of the early stage. At that time, it was called flipping the braille board. I only won an excellent award in the governor's cup. The appearance had no aesthetic feeling at all, because I directly modeled it from the structure. At that time, I thought that if I didn't even understand the structure of the rotating shaft, the appearance would have no design significance.

After entering the primary election of the governor's cup, some adjustments were made, and the page number square hole was added. writing the page number on braille paper can facilitate the sorting of braille paper, and the binding area of braille paper is set aside.

This is the physical hand board that flips the Braille board. The function is barely realized. The biggest problem is that the cover board is fixed by tight formula. The flip is not smooth and will fall. The discovery of these problems also drives the appearance of the second edition Braille board.

So the barrier-free braille board came into being to optimize the appearance. The cover plate slides smoothly, has accurate positioning and will not fall off. The upper and middle layers are magnetically attached, and at the same time, it is easier to lift up if it protrudes a little more than the bottom plate, so you can turn the page and touch it when you use it.

This is the structure of the sliding cover plate, which can be directly slid down and pushed up by lifting the cover plate.

I am personally very satisfied with the physical hand board of the barrier-free braille board. The function is perfectly realized and the feel of the arc is very good.

Finally, there is too much content and not much time to organize. Thank you for enduring such bad typesetting and picture quality. See here.
