Prosthetics · User-centred design · CAD · Additive manufacturing

CAD render of the custom semi-rigid hand prosthesis

Custom prosthesis worn by the user during a fitting session

User-specific design

Designed around one person,
not a standard size.

The project began with a user with congenital absence of the hand and partial wrist anatomy, looking for an affordable prosthesis primarily for everyday and social use.

The goal was a comfortable, personalized device that could also be worn under a glove to approximate the appearance of a natural hand.

Visual direction requested by the user: Deus Ex–inspired.

Functional development

Turning an aesthetic model
into a wearable prosthesis.

The initial geometry required functional development in SolidWorks to accommodate articulation, assembly, the residual-limb interface and additive manufacturing.

Aesthetic geometry → articulation → wearable architecture

Articulation

Positionable by hand.
Stable in use.

Each finger can be manually repositioned using the opposite hand and remains rigid in the selected pose.

The solution prioritised visual versatility and everyday simplicity rather than powered actuation.

Technical CAD overview of the two-drawer equipment integration enclosure

A rapid engineering project focused on packaging, integration and low-volume production of a custom drawer system for operating-room equipment.

System integration

Designed around
the equipment.

The project started from a defined installation envelope and the dimensions of the hardware that had to be integrated inside it. The challenge was to translate those constraints into a compact two-drawer architecture that remained accessible, manufacturable and suitable for installation within an operating-room workstation.

Packaging

Two drawers.
Different requirements.

The internal architecture was developed around the actual equipment rather than generic storage volumes. Each drawer responded to different component dimensions, clearances and access requirements.

Technical layout of the equipment-specific upper drawer — **Upper drawer**Equipment-specific integration

Technical layout of larger hardware within the lower drawer — **Lower drawer**Larger-volume hardware packaging

Engineering development

Every millimetre
had a purpose.

Component volumes, drawer travel, structural boundaries and installation clearances were coordinated within a tightly constrained envelope. CAD became primarily a tool for packaging and technical decision-making.

Aerodam
360

Dental Turbine Aerosol-Control Device

Dental · Clinical device · MJF · Project management

Aerodam 360 suction accessory in a dental treatment context

A compact suction accessory developed around the dental turbine to capture aerosol at source while preserving clinical access and one-hand handling.

Aerosol control

Capture aerosol
at the source.

Aerodam integrates suction directly around the turbine head, bringing the aspiration point closer to where aerosol is generated while keeping the assembly compact enough for clinical use.

Clinical integration

Built around
existing hardware.

The product had to integrate with an existing dental turbine rather than define a new instrument from scratch. Geometry, attachment, suction routing and overall volume therefore had to coexist within a very limited clinical envelope.

Piip Camo wireless camera held in a hand

A compact wireless camera redesigned around the practical constraints of professional on-set monitoring.

On-set hardware

A compact camera
built around real
production constraints.

The redesign focused on usability, camera positioning, thermal management and rapid battery replacement while integrating the existing electronics into a compact portable architecture.

Camera orientation

Reposition the view.
Not the whole device.

The camera module was integrated into a rotating turret, allowing extensive directional adjustment while keeping the main body in position.

This was a major usability requirement for an on-set monitoring device that may need to be placed or mounted in changing environments.

Electronics integration

Designed around
the hardware inside.

The enclosure architecture was developed around the existing camera, electronics, cooling components and power system rather than treating them as an afterthought.

Thermal management

Compact hardware
still needs to breathe.

Heat dissipation was a central constraint of the redesign. Internal packaging, ventilation geometry and cooling components were considered together with the external enclosure.

AER

A physical–digital platform for customizable contemporary hand fans.

Industrial Design · Digital Product · UX/UI · Generative AI · Production System

AER contemporary hand fan with a dark iridescent custom artwork

Physical product

A traditional object,
rebuilt as a system.

AER reinterprets the hand fan as a contemporary configurable product. Its architecture combines reusable structural components with interchangeable visual surfaces, allowing multiple collections and custom editions to be produced from the same core system.

Product ecosystem

The product does not end
at the object.

The physical fan was developed alongside the digital tools required to configure, generate, validate and manufacture each artwork. Product design, UX and production logic therefore had to be developed as one connected workflow.

Generative workflow

From an idea
to a manufacturable artwork.

A custom generation workflow allows visual concepts to be transformed into artwork compatible with the fan geometry and production constraints.

The system handles the transition between creative generation and technical output, including image composition, printable areas and production-ready files.

Design for manufacturing

Creative freedom,
inside production rules.

Artwork generation is constrained by the physical fan architecture, printing requirements and manufacturing tolerances. The digital experience therefore guides creative decisions while preserving a valid production output.
