P1 system - Protecting Firefighters

What it does

The P1 System enhances firefighter safety through a modular helmet equipped with Lidar, sensors, and an AR visor for better orientation in low visibility. Its replaceable parts reduce waste and adapt to various mission roles.

Your inspiration

Firefighting is one of the most dangerous professions, and each firefighter faces unique challenges based on their role. Existing helmets are often rigid in design, requiring costly replacements when components fail or wear out. I was inspired by the modularity of professional equipment in other fields and set out to create a helmet system that evolves with the task. The goal was clear: to design a solution that not only protects lives but is adaptable, cost-efficient, and sustainable in the long run.

How it works

The P1 Helmet System is built on a modular architecture that allows full customization for various firefighting tasks. At its core is a lightweight, heat-resistant duroplast helmet shell, reinforced with one of two protective adapters—each designed to meet different weight and safety requirements. The helmet features multiple connection points for essential attachments such as visors, breathing masks, lighting units, ear protection, and communication systems. Integrated Lidar, thermal sensors, and cameras feed data into an AR visor, which overlays navigation and hazard alerts in real time—helping firefighters stay oriented in smoke or darkness. Each component of the system is easily replaceable, enabling quick repairs and upgrades without the need to replace the entire unit.

Design process

The development began with interviews and field observations of firefighters during operations and training to understand their specific challenges. To assess feasibility, I visited production facilities to study helmet manufacturing processes and material limitations. Hands-on disassembly and testing of existing helmets revealed shortcomings in adaptability, repairability, and comfort. Close collaboration with firefighters throughout the research ensured that real-world needs guided every design decision. Early sketches explored modularity and intuitive attachment systems. Prototypes were 3D-printed with various connection methods, leading to a refined system of interchangeable parts and dual protection-grade adapters. The internal adjustment structure was redesigned for better ergonomics and balanced weight distribution. The AR visor underwent multiple iterations, evolving from basic overlays to a fully functional display powered by Lidar and thermal sensors—providing essential navigation support in low-visibility environments.

How it is different

Unlike conventional helmets that are rigid, single-purpose units, the P1 System is designed for adaptability. Its modular architecture allows each firefighter to configure the helmet according to specific roles—from ventilation to rescue operations—without compromising safety. While most current helmets require full replacement after damage or wear, the P1 enables quick, cost-effective part replacements. The AR visor, integrated with real-time sensor data, provides enhanced spatial awareness in smoke-filled or dark environments. Its dual-adapter system customizes protection levels without altering the core helmet structure, making it adaptable, upgradeable, and sustainable.

Future plans

Next steps include further prototyping and field testing with professional firefighters, refining the AR interface, and integrating AI-driven hazard detection. The goal is to develop a commercial-ready version and collaborate with safety equipment manufacturers. In the long term, the modular ecosystem will be expanded to include additional features. The ultimate aim is to create a fully networked, smart protective system that meets the demands of modern firefighting.
