Modular Backpack

Time and time over, I had always wanted backpacks that fit my needs. As of now, I can barely nudge my backpack into my school locker, and it is too small to hold all of my books. As a solution, I decided to create a modular backpack, one that can open up and replace the back section of the backpack with different attachments and modules to make the backpack larger, smaller, or just more conventient.

I created this in Fusion360, although 3D printing it may require a 3D printer. (I did not 3D print it.)

My inspiration was mostly the struggle I always have pushing my backpack into my already stuffed PE locker so that no one can steal my stuff. It also comes to hand that my backpack cannot carry half as much as I wanted, and that both ideas can't be solved at once currently. So, to solve both, I decided that a backpack that could change to your choice would be the most convenient.

In my drawings above in pen, I tried to detail a life sized representation of my modular backpack, and my modular backpack with different modules. The idea is that while the main module (the one with the arrow-button-seal) stays the same, the secondary modules (everything attached to the main one to complete the backpack) wouldn't. This is so that different sizes of the backpack could change, or even the design itself. I like suitcases personally, so a suitcase module was made for my liking.

In the pictures above, the CAD model is fairly simple. In gray (or grey) is the main module, the one that stays constant. The brown fabric models are the other modules, and in this case I made two. One of the modules is a basic, large, backpack. The other is the same shape, but with a suitcase handle rather than a backpack strap.

I started with a rectangluar shape that I liked, smoothed the corners, and then removed the interior to represent the inside of a backpack. Later, I attached little pins on each corner of the main module to stick in with any of the side modules. The side modules were the same, except that the pins were inverted to hold the main module. Then I added a strap to the main module to attach to any secondary module, as an extra security measure and fashion measure. To make each secondary module unique, I simply added a strap on one of them to create a suitcase holder.

To render, I showed each part of the backpack (modular-wise), and added a dummy + a table from GrabCAD to show the scale. The backpack, as previously stated, is large, and can be modified.

Although I had brought my long-awaited product to life, I don't feel excited or even glad it was made. If anything, I'm not contempt with the simplicity of my mediocre model. So, I decided a change would be for the better.

In the sketch above, again detailed in pen, I decided a more complex and appealing modular backpack with multiple different pockets (as opposed to one) would be more stylish and useful in real world situations. As compared to the block of a backpack previously, I would actually enjoy having this new design. It is ergonomic and clean in a sleek design that looks great on anyone. (There are multiple different modules this time too, which can appeal to customization.)

In the revised model above, there are multiple different parts, and a more realistic display. Detailed are different compartments within the backpack, and a version of an assembled backpack. The efficiency appeals, as it is suitable to any type of workplace, ranging from buisness to even school.

Above are two different renders of what the backpack could look like in different modules. One is assembled with every module, and the other is assembled with only the base part. Notice how different pockets and oppurtunities open per adjustment, and the possibility for the range of efficiency.
