Inside Nintendo Switch 2: What Its Patent Drawings Reveal

What is it?

The first patent was not conceived specifically for Switch 2. US10583356B2 has a 2015 priority date and describes a central display unit with two controllers that can be attached or detached.

What matters is that the controllers can send operation data to the main unit whether or not they are attached. The distinction between a self-contained portable console and a shared, separate-control setup is built into the hardware concept that Switch 2 inherits.

What is it?

US12691375B2 describes a controller with an elongated projection that fits into the console's side recess, magnetically attractable portions, and an electrical connection. It is more precise than the idea of attaching two objects with a strong magnet.

The recess and projection locate the controller; magnetic force holds it; terminals make an electrical connection. Nintendo's developer interview explains that magnets had been considered for the original Switch, but the connection was not stable enough at the time.

The same US12691375B2 also specifies a cavity and opening for a mouse sensor, located among features on the controller's attachment side. The interesting shift is functional: a face designed to connect to the console also becomes part of a pointing device.

Nintendo states that either Joy-Con 2 can function as a mouse in supported games by placing its console-facing side down and sliding it across a suitable surface. Patent claims describe component placement; the retail product page explains the resulting interaction.

What is it?

FIG.11 of US11871530B2 enlarges a narrow recessed area at the lower rear of the handheld device. A row of ribs 33 lines recess 22, and openings 32 between some of those ribs connect the exterior to the interior. Even a groove that looks like an incidental exterior detail is shaped to provide ventilation and structural support.

The patent considers several uses of this constrained space at once: where a folded stand sits, where air enters or exits, and how the console aligns when placed in a holding apparatus. The invention is less about a stand in isolation than about making a small stretch of the rear enclosure perform several jobs.

FIG.2 in US20250024631A1 is an exploded view of a handheld electronic apparatus. It separates the display panel 5 and thermally conductive sheet 25, the front housing half 20, circuit board 40, fan 60, rear metal sheet 50, battery 75, and rear housing half 30. It makes visible how much hardware must fit just behind a portable screen.

The patent's focus is on how air travels through that crowded arrangement. Heat-generating components can sit on both sides of the board, while intake air must reach the fan through confined passages. The disclosure proposes different clearances on the two sides according to the thermal load. The order of parts and the air space left between them are both engineering decisions.

Switch 2 can switch to television play by placing the console in its dock. The earlier US11171448B2 patent addresses a common physical problem: how to guide an electronic device onto the correct charging contacts when the user cannot directly see them.

The disclosure uses multiple fitting portions, an electrical contact, and movable components that can accommodate some positional mismatch. It treats the moment of insertion as a mechanical design problem, not just a question of supplying electrical power.

What is it?

In FIG.15 of US12246248B2, the right-hand grip 8b is shown partway detached from the main controller housing. The label “BOUNDARY PORTION” points to the junction of these pieces. The patent describes separate left and right grip members covering part of the seam between front and rear housing shells.

For someone holding a controller over a long session, the palms stay in contact with the grip surfaces. The described construction seeks to join the housing and grip surfaces smoothly and limit the uncomfortable step or seam the user might otherwise feel. Even a small boundary between molded parts can shape the experience.

What is it?

FIG.16 of US11497987B2 places an upright analog stick, shown with solid lines, beside its tilted position in dashed lines. The protruding portion 413 of the moving member 41 meets an internal pedestal 42. The figure labels the two contact points CPa and CPb and measures distances L3 and L4 from the shaft's center.

Rather than having the stick shaft rub directly against the edge of the housing opening, the mechanism limits tilt through a protrusion touching the pedestal inside. By bringing L3 and L4 close to the same value, the design aims to reduce relative sliding at these contact surfaces as the user moves the stick around its full perimeter, limiting friction-related resistance.

What is it?

Nintendo Switch 2's GameShare lets a system with a supported game invite other compatible systems to join without each running its own copy. An instructive precursor is US20170095735A1, which claims priority in October 2015 and was published in April 2017.

The patent's FIG.1 describes a master apparatus running application processing and generating images, client apparatuses that receive images and send their inputs back, and separate audience devices that view the output. It is not evidence that this exact patent was implemented in GameShare. It does, however, document an earlier Nintendo concept of one machine doing the game processing while several devices share in the experience.
