Nikon 1 J1
Camera's are highly complex products. A lot of high accuracy technology must be placed in a small body. Furthermore, heat that is generated in the sensor and electronics will have a significant impact on the design. For a correct functioning of the device, there should be thermal solutions that protect the components from overheating and the user from uncomfortable use.
Notice the large capacitor taking up a lot of space to power the flash.
The flash module is quite interesting. The long springs are kept in place by plastic rods. The linear spring mechanism is a relatively simple solution, which feels very stirdy. But it takes up more space in the camera body.
A lot of steel directly connected to the sensor, to manage heat.
Some small bended coper plates are used. They seem to be there for assembly, but since it is coper, it likely also forms a heat bridge between different steel parts.
Glueing a plastic part to a steel plate is a smart way to add fixtures to a steel cosmetic part, without the need for machining.
This are the smallest springs I have ever seen.
How to add a logo, without the need for an extra part: first spray painting in white, followed by a selective black layer.
To add stiffness between steel components that are positioned flat against each other, small pin-hole connections are used.
