Hand Paragon: Designing for Humanity

Hi, we are the Hand Paragon Team from the Panamerican Institute of Tampico, Mexico.

We are a group of students passionate about science and technology, seeking to improve the quality of life in our community. One of our favorite phrases states that we are “architects of our own destiny.” We believe that The Hand Paragon Team is turning classroom knowledge into life-changing solutions.

Our Story

In our city, we are surrounded by water and industry, yet there is a “dry spot” in our healthcare system that many people don’t see.

In Mexico, it is estimated that over 25,000 people who need a prosthesis lack access to one. Even more challenging is the situation for kids, as 60% of limb differences in Mexican children are congenital (meaning they were born that way). Furthermore, most available prosthetics for children are just “miniature versions” of adult models. These devices are often too heavy, causing back pain or skin irritation, especially in our hot, humid Tampico climate.

This is the challenge that our friend Daniel (Dani) faced. His original factory arm was a “heavyweight” that limited his movement instead of helping it. Because Tampico is a central hub for the Huasteca region – serving towns like Pueblo Viejo and Pánuco in Veracruz, and Altamira in Tamaulipas – we have a unique opportunity. If we can build a better arm for Dani right here, we prove that our community doesn’t have to wait for expensive, ill-fitting imports to help our friends.

Our Project

“Hand Paragon: Designing for Humanity,” is a student-led initiative dedicated to designing and manufacturing personalized 3D-printed prosthetics for children with upper limb differences. After we met Dani, a young student whose commercial prosthetic was too heavy and uncomfortable, our mission shifted from winning contests to driving human impact.

Our project aims to solve the lack of access to affordable, functional prosthetics for low-income families while restoring autonomy, dignity, and confidence to children. By treating each prosthetic as a “masterpiece of engineering and compassion,” we aim to: 1) create devices tailored to the user’s identity – such as an “Iron Man” themed arm with integrated lights – to ensure the children feel proud and empowered rather than different. 2) follow a rigorous technical workflow that begins with researching the muscular and nervous systems to understand how brain signals trigger movement. 3) Use advanced 3D modeling software, including Tinkercad, Fusion 360, and Blender, to simulate and optimize components before printing them with biodegradable PLA filament. 4) Follow an assembly process that involves innovative problem-solving, such as using bracket elastics as tendons, nylon fiber for joints, and high-strength fishing line for the mechanical pull system. 5) To address physical comfort, we will implement feedback-driven modifications, such as ventilation slots to prevent skin irritation, foam padding for softness, and adjustable velcro straps.

Ultimately, Hand Paragon is a “testimony of commitment to humanity” that transforms classroom knowledge into civic engagement. The project is entirely voluntary; we dedicate our personal time without academic credit to serve as “architects of our own destiny”. Through real-world testing and play, such as throwing balls or practicing fist bumps, we build strong emotional connections with users like Dani, helping children overcome social barriers and discrimination. By fostering empathy and technical excellence, the initiative seeks to inspire a new generation of active, open-minded individuals who believe that true innovation lies in the positive impact generated on others’ lives.

Project Steps & Timeline:

• Phase 1 (Design): Use Fusion 360 and Tinkercad to simulate muscle sensor placement (August – October).
• Phase 2 (Prototyping): Print iterative PLA models to test comfort, adding foam and ventilation slots based on Dani’s feedback (November – January).
• Phase 3 (Activation): Integrate muscle-signal sensors and code movement for “joy-based” actions, such as high-fives and holding a water bottle (February – April).
• Phase 4 (Delivery): Final fitting and community celebration (May).
