Everything has an inside story.
CUTAWAY ATLAS is a digital museum dedicated to the hidden ingenuity of everyday engineering. We dismantle, dissect, and document the silent mechanical choreography operating within the tools of daily life.

Interactive Kinematic Cutaway
Operate the mechanism step-by-step or toggle cutaway modes to observe how axial thrust transforms into rotary indexing.
Active Kinematic State
State 1: Retracted (Concealed Tip)
The return spring holds the cartridge and cam assembly in its rearmost position. The cam ribs are seated deep inside the housing longitudinal slots. The writing point is safely retracted.
Cam EngagementCam seated in deep guide grooves
Spring ForceLight pre-load compression (Rest)
Ballpoint StatusShielded within nose cone

Interactive Slider & Tooth Meshing Engine
Drag the slider handle vertically or use the keyboard buttons to witness how the interior Y-channel forces offset teeth into positive locking engagement.
Active Kinematic Phase
Closed & Interlocked
All alternating scoop teeth are nested projection-into-recess. Longitudinal and lateral forces are held in equilibrium by tooth shoulders, preventing unzipping under tension.

Open Complete Exhibition Dossier →The Swiss Lever Escapement
Interactive Swiss Lever Kinematic Simulation
Step through the 4-phase oscillation cycle or run in real-time slow-motion to see how the pallet jewels alternately lock and release the escape wheel.
Phase 1: Locking (Rest / Supplementary Arc)
The club tooth rests against the locking face of the ruby pallet jewel. Gear train torque is safely arrested. The balance wheel swings freely through its supplementary arc, detached from friction.
Escape Wheel:Locked stationary by entry pallet jewel (0 rpm)
Pallet Fork:Resting against left banking pin under draw angle
Balance Wheel:Freely oscillating past dead center (Natural period)

Open Complete Exhibition Dossier →The Dynamic Moving-Coil Loudspeaker
Interactive Electrodynamic Cutaway Engine
Adjust signal frequency, modulate electrical drive amplitude, and inspect the precision magnetic gap where electrical current converts into acoustic compression waves.
Lorentz Force Active: F = I × (L × B) driving axial piston displacement
When an alternating audio current (I) flows through a wire of length (L) immersed in a perpendicular magnetic field of flux density (B), it experiences a physical force F = I · L · B. Because the magnetic field is stationary, this force pushes the voice coil forward and backward along its central axis with a magnitude and direction proportional to the instantaneous electrical signal.
Magnetic Air Gap (B):1.15 Tesla (Uniform Perpendicular Flux)
Voice-Coil Excursion (Xmax):±2.8 mm (Dynamic Stroke)
Acoustic Output Mode:Audio Muted

Open Complete Exhibition Dossier →The Gravity-Fed Siphonic Toilet Flush
Interactive Hydraulic Cutaway · Gravity Cistern & Siphonic Trapway
Actuate the trip lever to witness flapper buoyancy unseating, toroidal weir siphonage, dynamic siphon-break gulping, and dual-action cistern & bowl water-seal replenishment.
Hydraulic Stage: 1 / 5Static Hydraulic Equilibrium
Stage 1: Equilibrium / Ready State
Cistern is filled to operating waterline. The buoyant rubber flapper is firmly pressed down onto the valve seat by hydraulic head pressure. The float arm keeps the fill valve orifice tightly closed. The bowl maintains a pristine standing water seal above the trapway weir, blocking all dangerous sewer gases from entering living spaces.
Gravity Cistern ReservoirCistern at 100% capacity (approx. 1.28–1.6 gal). Static pressure seals flapper.
Flapper & Fill Valve MechanicsFill valve shut off by elevated float arm. Flapper firmly seated.
Bowl & Siphonic TrapwayBowl water seal level at weir height (intact gas-tight barrier).

The Curatorial Principle
“To understand how a thing works inside is to understand the human mind that gave it form.”
Modern digital life isolates us behind seamless glass and monolithic casings. CUTAWAY ATLAS restores reverence for the physical world—celebrating the detents, cams, springs, and interlocking wedges that turn human force into reliable mechanical purpose.
