Wire roller

Ce qu'il fait

Due to the strain and injuries caused by manual fencing, this product offers a safer way to work: it attaches to a drill and automates the knotting process. It's a wire roller that boosts productivity through an ergonomic and sustainable solution.

Votre source d'inspiration

The idea came after visiting a rural area in Argentina and witnessing the physical strain involved in fencing work. In interviews, fence workers shared that manual knotting is one of the most demanding tasks, often leading to long-term issues like arthritis and osteoarthritis. I saw a clear opportunity to improve their quality of life with a simple, ergonomic solution that adapts to tools they already use, such as a drill.

Comment ça marche

It is an accessory that easily connects to a standard drill. It automates the process of making the wire knot, which fixes vertical rods to horizontal wires in fences. The user places a staple on the rod, locks it into the device’s head, and by triggering the drill, the wire wraps automatically around both sides of the staple, forming the knot. This reduces the time and effort required per knot and allows one person to do a task that typically takes two. It also helps maintain fence integrity, preventing livestock from escaping and protecting crops.

Processus de conception

I began by interviewing over 50 fence workers in rural Argentina. Based on their insights, I focused on reducing physical effort and work time. Initial stages included sketching concepts and exploring mechanical systems. I designed technical plans and built mock-ups to test proportions, materials, and ergonomics. The first prototype used four laser-cut metal gears and a central grip. I later integrated an eccentric ring to simplify wire insertion and reduced the mechanism to three gears. I redesigned the grip for better handling and experimented with multiple sizes and shapes. Switching to nylon bevel gears improved durability, lubrication, and noise control. I also developed a specific geometry to prevent wire misalignment and applied FEA simulations to optimize dimensions and materials. The grip system was refined using two metal parts embedded within the gear. Final prototypes focused on tolerances, assembly, and field durability.

En quoi est-il différent ?

This product fully automates a task that, until now, has been done manually and is physically demanding. Unlike homemade or improvised tools, it is lightweight, ergonomic, and compatible with standard drills, making it accessible and easy to use without requiring new machinery. It is made from recycled plastic, reducing its environmental impact without compromising durability. The device can be operated with one hand, and its robust design is suitable for harsh rural conditions. It is a practical, functional solution—designed directly from real-life needs in the field.

Plans pour l'avenir

I’ve distributed 3D-printed versions of the device to fence workers for real-life testing. Based on their feedback, I’ve validated the design and identified improvement opportunities. My next step is to partner with rural equipment manufacturers to move toward scaled production. I plan to offer a complete kit for various fencing tasks and aim to commercialize the product in Argentina and in other countries with extensive livestock farming.
