KOR'K Sensor 02 First ideas

Chapter 02

The first ideas

Before any calculation, hand-drawn sketches, in May 2025. Then AI-generated renders, in June 2026. Then the shape changed three times, each time for a specific reason.

May 2025

My early explorations

It all started on two sheets of squared paper. I was looking for an object that would be forgotten in a bedroom, and would find its place naturally. The numbered markers show what each drawing became.

Sheet 1
The shapes

Squared-paper sketch sheet: a diamond with a lens, a pebble, triangles, hanging versions and three shapes placed in a corner.
  1. 1The diamond. The lens at the centre of a diamond: this is the shape that became the “Diamond” facade of the kork.fr website, then of the prototype.
  2. 2The pebble. An arrow towards a softer shape. I took it into 3D, before coming back to the diamond (step 6).
  3. 3The rounded triangle. The lens in a triangle with rounded corners: the corner of the room seen head-on.
  4. 4The triangle with a “K”. A variant that carries the K of KOR'K.
  5. 5The hanging versions. Objects hung from a string. I did not keep them.
  6. 6Three shapes in a corner. A sphere, a cube and a trihedron placed in a wall corner. The trihedron, which fits the corner, became the back of the housing.

Sheet 2
The corner and the components

Sketch sheet: a trihedron in a circle, a room with a cone of vision from the ceiling corner, a version annotated camera, microphone and speaker, and rounded shapes.
  1. 1The trihedron up close. The shape that fits into a wall corner.
  2. 2The cone of vision. From the corner of the room, what the camera sees. This idea became the placement study: at what height, at what angle (chapter 05).
  3. 3Version 1, annotated. A camera and a sensor at the centre, a microphone, and a speaker. I set the speaker aside for the prototype: it added nothing to what had to be shown in Nuremberg. I am keeping it as an idea for later: one day, the device may be able to communicate.
  4. 4The rounded shapes. Trihedrons with softened corners, and a pebble: the leads that followed.

The first renders, with Vizcom

I then gave the sketches form with Vizcom, an AI rendering tool. This is where the white diamond with a fabric front appears, the one you find on kork.fr. These images do not show a real object: they helped me choose a silhouette.

How the shape evolved, and why

Once in 3D, each shape was checked by calculation before being shown: no component outside the shell, no collision. It was the calculation that ruled out the first one.

  1. Step 3

    Facet

    Comparison of the facet shape and the pebble shape, with the electronics.

    A tetrahedron with a flat face: about 165 cm³ inside, and 87% of the Raspberry Pi stuck out of the shell. It would have had to be enlarged by 40%.

    Ruled out by calculation.

  2. Step 3

    Pebble

    The pebble-shaped housing in the corner of a room.

    An eighth of an ellipsoid, about 623 cm³: everything fitted, with at least 1 mm to spare.

    Kept for a while, then replaced.

  3. Step 6

    Diamond

    Three facade variants of the diamond-shaped housing.

    The website's diamond was stronger, and the prototype had to look like what visitors see online. A flat top brings back the trihedron; the camera is tilted by 20°.

    Chosen: the V1, true to the website.

  4. Steps 7 and 8

    V1 with Raspberry Pi 5

    The chosen facade, lens blended in, shutter open.

    The Raspberry Pi 5 sits on the axis, behind the camera: the housing grows to 12.4 cm along the walls. The facade is softened.

    The Nuremberg prototype.

From sketch to prototype

  • The diamond from sheet 1 became the facade.
  • The trihedron placed in the corner became the back of the housing.
  • The cone of vision from sheet 2 became the placement study.
  • The speaker was set aside for the prototype, but it remains an idea: one day, the device may be able to communicate.

Step 8

Not looking like a surveillance camera

I wanted an object that works in real life, not only on a stand. I had seven facades rendered, and the one I chose combines more rounded edges, a lens blended into a small dark window, a hidden privacy shutter (a small button slides a white disc in front of the lens) and a warm white indicator light.

Seven facade variants of the housing, from the most “camera-like” to the softest.
