RESEARCH & DRAWING NOTES

Look closer.

Eight studies of Braun’s design language. Exterior proportions, controls, dates and credits are grounded in the references below.

The exploded views are interpretive diagrams, not factory drawings or disassembly instructions. Major components are shown separately; concealed fittings, circuit layouts and spacing are simplified. Parts follow rigid extraction axes with clearance in the separated views. This is a geometric animation, not a gravity, electrical or manufacturing simulation; perspective can still place one part in front of another. Rotate the 3D view to inspect their separation.

01 / SK 4 · 1956

Dieter Rams and Hans Gugelot. Painted metal, wood and plastic; 58.4 × 29.2 × 24.1 cm. The clear hood, wooden sides, turntable and radio layout define this study. The concealed chassis is schematic.

02 / T3 · 1958

Dieter Rams with the Ulm School of Design. Plastic casing; 15.2 × 8.3 × 4.1 cm. The component study includes the speaker, tuning assembly, transistor circuitry and four AA cells. Component placement is simplified.

05 / ET 66 · 1987

Dietrich Lubs, within Dieter Rams’s Braun design team; the museum record credits both. 13.7 × 7.8 × 1.1 cm. Round convex keys and an eight-digit display. Key contacts and electronics are schematic.

Museum Angewandte Kunst collection record Mark Adams on Dietrich Lubs and the ET 66

03 / TP 1 · 1959

Plastic casings, an aluminium frame and a leather strap. The T4 radio and P1 player are removable modules. The underside pickup is represented as a simplified mechanism.

04 / LE 1 · 1960

Metal cabinet, perforated front and nickel-plated steel stand. Date and overall measurements follow MoMA; other archives date the design to 1959. Electrostatic layers are schematic, with exaggerated spacing and membrane thickness for visibility.

06 / RT 20 · 1961

Dieter Rams. Overall proportions follow SFMOMA; control arrangement and circular slotted grille follow archival photographs. The concealed valve chassis is schematic.

07 / HL 70 · 1971

Reinhold Weiss and Jürgen Greubel. Dimensions and date follow MoMA. The cross-flow rotor, motor cylinder and transparent support follow photographs; concealed motor details are schematic.

MoMA: HL 70

08 / AB 1 · 1987

Dietrich Lubs. A compact square alarm clock with a circular dial. Dimensions are approximate; the quartz movement and gearing are schematic, not a working timekeeping simulation.

Wright: AB 1 attribution, date and materials

An independent design study. Not affiliated with Braun. The line models were created for this experience; archival photographs are linked for reference.
