Samsung Patents a Modular Camera Stack That Chains Units Together on One Board

By Patentlyze Team · Updated May 29, 2026

Samsung is rethinking how multiple camera modules wire into a phone — instead of each camera running its own cable to the main board, this patent describes a system where one shared circuit board carries signals from several cameras in a chain.

What Samsung's daisy-chained camera structure actually does

Imagine your phone has three cameras on the back. Right now, each one typically needs its own ribbon cable running all the way to the main circuit board — that's a lot of wiring crammed into a very thin space.

Samsung's patent describes a different approach: stack the camera modules so they sit right next to each other, connect them with small metal contact pins, and let one shared circuit board carry electrical signals from all of them back to the main board. It's a bit like a power strip — instead of three cords going to the wall, you plug everything into one strip and run a single cord.

The first camera module does the heavy lifting here. Its circuit board extends toward the main board and carries the wires for the second camera too. The modules physically couple together, so the whole camera cluster acts more like one integrated unit than a collection of independent parts.

How the shared PCB routes both cameras to the main board

The patent describes an electronic device — clearly a smartphone — with a first camera unit and a second camera unit that are mechanically and electrically integrated.

Each camera unit has its own printed circuit board (PCB), image sensor, lens assembly, and a housing (the metal or plastic shell around the optics). The clever bit is how they connect: instead of flexible cables, each housing has contact pins — small metal contacts on the outer surface of the housing that physically touch and connect to the PCB sitting beneath them. No soldering, no separate connectors.

The two housings are at least partially coupled to each other, meaning they lock or nest together mechanically. Critically, only the first camera's PCB extends all the way to the main board — and it carries the electrical wires for both camera units. The second camera's signals piggyback on that same board rather than needing an independent path.

• Contact pins on housing surfaces — replace traditional flex connectors
• Coupled housings — cameras physically attach to each other as a cluster
• Single shared PCB path — one board routes signals from both cameras to the main board

What this means for thinner, denser multi-camera phones

Multi-camera phones keep adding lenses — ultrawide, telephoto, periscope — and every additional module traditionally means another cable, another connector, and more routing complexity inside an already packed chassis. Samsung's approach could reduce the number of discrete connections and simplify assembly, which matters both for manufacturing yield and for keeping modules thin and tightly packed.

The contact-pin-on-housing design is also notable because it eliminates fragile flex cables between camera modules, which are common failure points. If Samsung can make this reliable at scale, it could quietly improve the repairability and durability of multi-camera arrays — something that rarely gets talked about but that matters to anyone who's ever dropped their phone.
