DEFENCE CONTEXT · PRODUCT CONCEPT
Ergonomic prototype + refined concept

Designed around the person on the flight line.

T-REX explores a hands-free AR helmet for military aircraft engineers. Research, sketching and a physical fit model helped turn an ambitious feature list into clearer requirements for ventilation, stability, protection and controls.

3Stages: research, prototype, refinement
4Key ergonomic issues identified
1Revised full-face direction
01The working environment

Complex work needs less distraction.

Aircraft maintenance combines physical access, detailed information and demanding environmental conditions. I explored a wearable architecture that could bring diagnostic information into view while considering noise, airflow and protection.

The research moved from broad military roles toward jet engineers. The design question became how information and protective equipment could work together without adding another object to hold or another control to search for.

01

Information

Proposed schematic overlays and hands-free diagnostics.

02

Environment

Consider airflow, noise and conditions around aircraft.

03

Interaction

Keep adjustment and frequently used controls accessible.

02Concept exploration

Sketch the relationships, not just the shell.

The sketch studies explored how a visor, ear protection, sensing and ventilation could occupy the same wearable form. The different arrangements helped compare coverage, proportion and interaction.

Robust curving forms and material separation became part of the visual language. But form studies alone could not resolve whether the object would sit securely or leave enough working clearance.

Original concept sketches exploring form, protection and interaction.
03The turning point

The first prototype challenged the concept.

The physical model revealed poor ventilation, incorrect ergonomic assumptions, an unreliable adjustment mechanism and insufficient stability and clearance. These were fundamental architectural problems.

I returned to the brief. The revised direction called for a tighter, more secure fit, a full-face protection concept and simpler controls: side scroll wheels for adjustment and buttons accessible from below.

01

Ventilation

Reconsider the openness and airflow of the architecture.

02

Fit + stability

Secure the helmet before layering in advanced functions.

03

Controls

Simplify adjustment and button positions.

04Refined direction

Translate failures into design decisions.

The next CAD direction brought together an open rear airflow approach, a larger rotary side control, front sensing and a filtered full-face protection concept. The annotations record where those decisions came from.

The final visualisations communicate the intended system. The revised architecture was not physically prototyped within the project timeframe; AR, filtration, thermal vision, noise cancellation and protection performance remain proposed functions.

OUTCOME + REFLECTION

A more grounded second brief.

The value of the project is the transition from an ambitious wearable concept to requirements informed by physical ergonomic failures.
