The story behind the project

This project began as a very special collaboration between my father and me.

My father is 81 years old and belongs to a generation of draftsmen who learned to design with pencils, compasses, rulers and set squares. For him, a design did not begin on a screen. It began on paper, measuring, drawing and imagining every shape by hand.

We needed to create a device that could help someone with limited mobility put on their socks. I needed it while recovering from surgery, and it may also be useful for my mother, who lives with chronic osteoarthritis, as well as for many older people or anyone who has difficulty bending down.

I asked my father to design the object exactly as he would have done throughout his professional life: with a technical sketch drawn completely by hand.

Using that drawing, I transferred the measurements and shapes into Fusion 360. The paper became digital geometry, the geometry became a three-dimensional model, and the model was finally brought into the physical world through 3D printing.

The result is much more than a plastic object. It represents the union of two generations and two ways of creating:

the precision of traditional technical drawing and the possibilities of digital manufacturing.

My father was able to watch an idea that he had imagined and drawn on paper become a real, functional object. For me, that moment perfectly represents the spirit of Fusion Signature and Inventarix: preserving knowledge from the past and combining it with modern technology to create solutions that improve people’s lives.

How it works

The sock is stretched around the curved body of the tool, while its opening remains accessible for the foot.

The model includes several guide slots through which two straps, approximately one metre long each, are threaded. Once the sock is prepared, the user places their foot inside and pulls both straps towards their body.

As the device moves closer, the sock slides progressively over the foot and ankle without requiring the user to bend down completely.

Required items

• One 3D-printed sock aid.

• Two strong straps, approximately 1 metre long each.

• One sock.

Flat straps that are comfortable to hold and do not stretch excessively are recommended.

Instructions

1. Thread both straps through the guide slots.

2. Stretch the sock around the curved body, leaving its opening accessible.

3. Place the tool on the floor in front of the foot.

4. Insert the foot into the sock.

5. Gently pull both straps towards you.

6. Continue pulling until the sock is correctly positioned.

7. Carefully remove the tool.

Important

This design is a household assistive tool and is not a certified medical device. Use it while seated, on a stable surface, and avoid sudden or forceful pulling.
