Form and engineering,
decided together.

Built for the worst case on the trail.

The footpeg has to hold up in a rough off-road setting — a heavily kitted rider, stiff boots, vibration, mud, the occasional second foot resting on it. That pushed the project past styling and into the full chain from parametric geometry to printed titanium.

Fixed interface, longer support, controlled geometry.

A parametric skeleton controls the critical dimensions: 160 mm length, 50 mm width, 5° inward tilt and 85° relative to the side plane of the motorcycle. The CAD work resolves the transition from the bike interface to a longer, lighter support surface.

The rib pattern comes from the load path.

Two load cases mapped the structural behaviour: 5 kN at two-thirds of the support plus 5 kN frontal load; and 3 kN at one-third and two-thirds plus the same frontal load. Both studies pointed to a diagonal main rib with secondary reinforcement near the interface and tip. The final geometry reaches the minimum safety factor target of 1. Maximum von Mises stress appears around the interface and decreases through the rib network. Maximum displacement is located at the far tip and remains controlled at 3.43 mm.

Print orientation, build plate and jig close the loop.

Bambu Studio was used for rapid orientation studies, then nTop for support generation and build-volume distribution. The final orientation is 40° in X and 27° in Y, with an estimated 22.3 g of titanium supports per part. The jig fixes the printed part for repeatable machining of the spring-hole interface.

Function before appearance.

It's a scan-based prosthesis, and the gyroid body does most of the work — softness and airflow. An internal tree adds support, the edge keeps it off the skin, and a textile layer makes it comfortable to wear all day.

The surface is the mechanism.

The gyroid is the core functional decision. Its continuous porous wall creates an open structure for airflow and cleaning, while the thickness and density can be tuned to approach a soft viscoelastic response.

The object is generated, not sculpted.

The model is built as a parametric system: breast volume, gyroid field, trimmed lattice, internal branching and controlled density. This makes the prosthesis adjustable to different scans and cup references instead of being a single fixed shape.

Porosity comes from structural logic.

Natural cellular systems and breast biomechanics explain the project’s structure. The prosthesis needs lightness, distributed load paths and differentiated support between softer adipose behaviour and denser internal tissue zones.

One tool for peeling and cutting.

Stone pine grafting is still performed manually with scalpels: low throughput, short seasonal window, high skill dependency and blade-injury risk. The tool compresses peeling, vertical cut, horizontal cut and diagonal cut into one guided handheld system.

Guided notches and adaptive holes structure the action.

The tip includes two circular holes for bark peeling by rotation. Their effective diameter changes with the opening angle of the handles, adapting to different branch sizes. Behind the tip, the guided notches stabilise the scion/rootstock for vertical, horizontal and diagonal cuts with one replaceable blade.

Simple assembly, standard parts.

Six-component logic: top handle, bottom handle, 40 mm razor blade, torsion spring, two M3 screws and two M3 nuts. The blade can be replaced by loosening one screw; no adhesives or welds are required.

High safety factor, clear critical zones.

FEA checked spring torsion and peeling load. With PVC as reference body material, the study reported 2.77 MPa maximum von Mises stress in torsion and 4.257 MPa in peeling, both far below the 45 MPa yield strength. The resulting safety factors are 16.25 and 10.57.

Robust polymer body, metal blade, forestry setting.

The design language stays direct: matte polymer volumes, exposed metal hardware, visible hinge logic and a replaceable blade. The contextual reference is the stone pine environment, because the object belongs to a specific agricultural process.

Mechanical redesign around a fixed electronic core.

The power board and LED board stay untouched; the work goes into the shell, the diffuser path and how the unit is opened for service. The point was simple: make the status readable at a glance and the charger easier to install and live with.

The LED is treated as a perimeter interface, not as an added indicator.

The light path wraps the geometry and converts status feedback into a readable spatial cue. The diffuser is integrated into the shell section rather than applied as a separate frontal token, which gives the product a more coherent visual signal both close-up and from distance.

Cover, diffuser, board and base are separated into a readable stack.

The assembly is organised into an upper cover, the LED support and diffuser, the internal power board, protection elements and the lower housing with cable entry. This reduces ambiguity during assembly and gives each part a clear role.

The form is reduced to a robust enclosure with a single recognisable signature.

Instead of breaking the front into panels and details, it uses a few chamfers, a recessed centre and the light loop to hold everything together. It ends up reading as a compact, protective object you recognise as a home charger.

Proposal II: monomaterial PP table.

The final concept is not a mix of the three early routes. The chosen proposal is the monomaterial one: a recyclable PP table where the product language, structure and circular model all point to the same decision.

Make the table easier to produce, recover and recycle.

The redesign moves away from an assembled object made from several materials. A single PP body reduces separation problems, simplifies the product story and makes the return loop more believable.

The numbers behind the monomaterial decision.

The comparison quantifies why the monomaterial route was chosen: a reported 58% reduction in environmental impact against the multi-material original.

Three load cases, three buckling results.

Each case reports its applied load and the resulting buckling deflection, read directly from the simulation.

How the table re-enters the loop.

The lifecycle and business diagrams map the full circular path: recovery, transformation, fabrication, use and return, reintegration and second life.

A platform for reading conflicts through connections.

The MVP uses generative technologies to gather multiple news accounts, compare their perspectives and organise them with contextual data so the reader can understand an event as a system rather than as a single headline.

The feed shows the shock. Xatrac shows the conditions.

Wars, climate events and political crises are usually consumed as isolated fragments. Xatrac slows that logic down and exposes causes, actors, narratives and gaps in the evidence.

Event, context, perspectives, uncertainty.

Collect the event. The system starts from a current conflict or crisis and pulls different journalistic accounts instead of relying on a single source.

Add structure. Country data, historical conditions and surrounding relations are attached to the event so the headline can be situated.

Read perspectives. AI is used to compare the narratives, detect emphasis and reveal where the accounts converge, diverge or omit information.

Map uncertainty. The interface returns a causal map that helps the user see connections and also keeps the unknown parts visible.

The news feed isolates effects from causes.

Most interfaces privilege immediacy because speed increases consumption. That mechanism compresses time and hides the structures that produce the event, so the reader reacts to impact without seeing the wider configuration.

Direct violence is visible. Structural violence is slower and harder to see.

Xatrac links immediate events with long-duration pressures such as unequal resources, constrained mobility, institutional force, trade dependencies and the media narratives that make those conditions appear natural.

Collect, compare, connect, explain, refuse false certainty.

The intended workflow gathers different sources, compares their framing, connects the event to broader structures and proposes explanations only when the mechanism is grounded. When the evidence is weak, the system must show the doubt instead of fabricating closure.
