Tesla’s Unboxed Manufacturing Course of — How It Works & Why

The automotive world is all atwitter this week with information that the US Patent Workplace has awarded two new patents to Tesla for its so-called “unboxed manufacturing course of.” The thrill is that the method will enable Tesla to construct automobiles extra shortly with fewer human employees at decrease price in smaller factories. Many are calling it the best advance in car manufacturing since Henry Ford created the meeting line.

Let’s start by explaining what “unboxed” truly means, as a result of for a lot of (together with myself), the time period will not be self-defining. Within the conventional auto manufacturing course of, first a set of metallic stampings are assembled to make the physique of a car. That meeting is actually a field into which all of the methods that may flip it right into a functioning automobile should now be put in.

Slipping a dashboard in by means of a door opening could be executed — in reality there are robots designed particularly to carry out that activity. However wouldn’t it’s simpler to suit the dashboard, with all of the controls, air vents, touchscreens, and wiring hooked up, to a entrance sub-assembly earlier than it will get mated to the remainder of the automobile? In that case, the entrance sub-assembly is accomplished earlier than the “field” is completed. That’s the concept behind “unboxed” manufacturing in a nut shell.

Sawyer Merritt, a tireless cheerleader for Tesla, described the method this fashion:

The issue with meeting traces is, if issues go awry at one location — there are not any seats to put in when wanted, for instance — the complete line stops. Each meeting line has controls at numerous factors that enable employees to cease it, however woe betide anybody who makes use of considered one of them to carry the method to a halt!

Consider it like a military crossing a river on a bridge that’s solely large sufficient to permit individuals to stroll throughout it in single file. If one solder breaks a leg on the way in which throughout, the complete procession grinds to a halt. Within the “unboxed’ mannequin, there are a number of bridges throughout the river and the assorted streams of troopers assemble themselves right into a functioning preventing pressure on the opposite facet.

Not A Tesla App says, “This new methodology is a producing revolution that builds a automobile extra like a LEGO set than a standard car. The Unboxed Methodology is a radical, high-level idea that’s getting nearer to actuality. It goals to scale back manufacturing facility footprints and manufacturing prices in half, whereas dashing up manufacturing to blistering speeds. [The] two new Tesla patents define how they intend to show this methodology from an idea right into a concrete, engineered actuality.”

The video under did the very best job of explaining the idea, regardless of a quick promotion early on. When you get past that, the graphics and embedded movies do a very good job of explaining what “unboxed” is all about.

Ache Factors & The Unboxed Course of

One of many ache factors within the course of of producing an car is corrosion resistance and portray. Usually, as soon as the “field,” or physique construction, is accomplished, it’s dipped in a shower of corrosion-fighting chemical substances. Usually, the doorways, hood, and trunk lid are in place when that happens.

Afterwards, the “field” goes to the paint store, the place the complete physique will get painted in and out. As soon as the paint is absolutely dried, the doorways, hood, and trunk are sometimes eliminated to permit the robots and employees concerned in putting in the inside to entry the within of the “field.” These elements are put aside and should transfer together with the physique till all the inside becoming is completed, at which level they’re reinstalled.

Within the “unboxed” mannequin, the doorways, hoods, and trunk lids obtain their corrosion resistance remedy and are painted individually and fitted to the physique solely in any case the inside items are in place. Then the battery pack, drivetrain, brakes, wheels, and tires are fitted.

Cheaper & Sooner

The hoopla concerning the “unboxed” patent facilities on its capability to permit Tesla to construct cheaper automobiles quicker. A lot is made about how this presages the factories of the longer term. And but, Tesla gross sales haven’t matched expectations for the final yr or so, partly as a result of political antics of Elon Musk.

A number of years in the past, we heard rumblings a few huge new Tesla manufacturing facility deliberate for the state of Nuevo Leon in Mexico. It was extensively assumed that manufacturing facility was the place the corporate would construct its subsequent new mannequin, the $25,000 “Mannequin 2” or “Mannequin C” that everybody claimed Tesla was engaged on.

Then we discovered Musk had personally put the kibosh on the cheaper mannequin to focus on automated driving methods. Information a few new manufacturing facility in Mexico dropped off all people’s radar display. After which, the particular person Elon supported for president with as much as $300 million of his personal cash disrupted many years of secure commerce relations with Mexico and Canada by firebombing industries with punishing new tariffs.

When you watch the video fastidiously and parse what others are saying concerning the “unboxed” manufacturing mannequin, you’ll discover {that a} key aspect of the method is utilizing high-pressure castings for the entrance and rear of recent autos. That may be a novel concept that was first deployed at scale in constructing the ill-fated Cybertruck, however is now being adopted by different producers.

Musk and his minions have certainly created a extra environment friendly method for constructing cars — one which exposes the restrictions of Henry Ford’s linear meeting line. However there’s one factor Ol’ Henry knew that Musk has forgotten. Henry made certain his employees may afford to purchase his autos.

When you watch the video, you will note tons of of robots however comparatively few employees. Whereas Tesla says its persons are compensated extra generously than employees at different automakers as a result of they will earn inventory choices, the query is whether or not they can afford to buy the automobiles they’re serving to to make?

Self-driving automobiles are an intriguing dream, however some say one such car can do the job of ten privately owned autos. How is {that a} recipe for elevated gross sales and why does making automobiles extra effectively assist the corporate if it sells fewer autos? We grant the “unboxed” idea is sensible, however does it benefit all of the hype that’s surrounding it? That’s one thing our readers might have an opinion about.
