This is in the continuation of the last week’s post. I thought I will be able to finish it in this one, but I think I will continue this week-end special for a while. In this post we go further in the product.
This is the 3D drawing of the camera module. There were few very important issues which were to be resolved. We designed it for 185 degrees rather than for 180 (in most of the cases you will be holding it in such a way that it is not exactly facing you, so providing a little bit of offset). You might feel that 5 degrees isn’t much, but then for Adam its 5+3 degrees of natural inclination, so around 8 degrees (some relief when it’s on table) There are 2 rings on each side of the camera shaft which stops the module at all the angles. For connectivity, we designed a very special FPC which could sustain the usage cycles we were looking at. Believe me, this was THE most difficult job in the whole project (moving components always cause problems like Blackberry’s trackball). There are tremendous possibilities in the combination of Swivel design and Auto Focus Feature (from surveillance, notes while taking images, notes while taking video lectures to augmented reality!).
Next comes the batteries. It’s a 3 cell battery which you find in the laptops. There are very serious laws and regulations which one needs to follow while designing product with batteries as they are dangerous! We have 3 level of protection to stop any leakage or damage. First is on the batteries itself. Second comes from the body of the device and third from that green section (mesh plate). Ever wonder why is it there? It has beautiful automobile mesh texture which helps you grip, adds class to the over all design and acts like the 3rd protection for batteries. You will find that there are 2 parts in this product (one is this mesh plate) that you can customize with your choice of color!
This is the exploded view of the whole device (not updated). At the bottom you will find the device casing which holds the track-pad as well. Above this you will find the mother board (not visible in this drawing) and the screen (dark brown part which is visible). The green part is a Magnalium Alloy Chassis which provides the strength to the whole device. Its light, strong and designed to resist shock propagation to other components (due to which they are used heavily in Aircrafts). And the top most section is your capacitive screen (4 Layers in all) with the protective Glass (THE costliest component). Your Tegra chip nicely sits below the screen (Tegra module is extremely small!).
I have tried my best to pay heavy attention to the detailing in the product and the UI (and hoping you might like it!). It took us some 11 iterations before we finalized this +/- key design. Even for the toggle button (deep sleep/turn off), there were loads of iterations.
It has been an extremely fulfilling experience to see the product taking shape from sketches to rough mechanical prototypes, to CAD files which can be used to mill product out and finally to the complete render of the product.
Below is one more render of the product (mesh plate)(I know you have seen a lot of renders and now waiting for the final pictures and in the post to come on 9th Oct, I will show you the final device right from our factories).
I was thinking of posting a poll to understand your color choices for the devices. Let me know if you all are up for the same (in the comments). I feel that is one more way to get you all closer in designing Adam!
Here is the final image of this post.
