Smart Brick
>Where the battery and charging coil are located in the Smart Brick is revealed by a patent for the brick itself: EP4591961A1 . Not only do we get an astonishingly detailed look at the brick's structure, but we also get confirmation (paragraph 161) that in addition to the charging system, processor, and communication components, it is also supposed to contain two LEDs , a loudspeaker, and a microphone , as well as an acceleration sensor and an unspecified "sensor system." A color sensor, which we had suspected based on the colorful geodes in the test sets and a side window in the brick's casing, is not explicitly mentioned here. However, it is mentioned in the patent specification WO2025157587 A1 for the brick's circuit board, where it refers to a light sensor for color measurement ("light detector [...] configured for color sensing"). A (future?) possible, extended version of the circuit board is also described, which could then contain, among other things, an infrared emitter, for example for communication or – in conjunction with the light sensor – as an optical motion sensor.
>Particularly interesting is the information that the brick is supposed to contain several coils arranged parallel on all sides. The purpose of this becomes clear when you take a look at the patent EP4591961A1 (“ELECTRONIC DEVICE WITH MULTIFUNCTION MAGNETIC SYSTEM”). This shows that the Smart Brick is apparently supposed to be able to detect the relative position of other system components . If I understand correctly, signals are received from all three spatial directions (with the respective coil), and the location of the other component is then determined based on the signal strength. So if, for example, a minifigure with a tag is standing to the right of the Smart Brick, the signal from this direction will be stronger than, for example, the signal from the “up/down” or “front/back” measurement.
