00:26	in this video , we're going to go over an
00:28	example design process . The steps that we're going to
00:31	cover include observing the world around you , brainstorming solutions
00:38	, comparing ideas , making prototypes , to test ideas
00:43	and repeating steps all to solve a problem . Welcome
00:48	to the Product design lab . Now here MIT students
00:51	will practice product design in product design . You start
00:55	off with a problem and then you design a product
00:58	or a service that ends up solving that problem .
01:02	Now engineers will learn as much as they can in
01:04	order to be effective designers that way they can use
01:07	that they've learned in order to help people . We're
01:10	gonna be going over something like a recipe that will
01:13	help teach you more about design . one good place
01:17	to start is with an observation . Now an observation
01:21	. You just pay close attention to the world around
01:23	you and you look for any problems that you might
01:25	be able to solve by designing something . You can
01:29	pay close attention to things at school or while walking
01:33	around outside . Yeah . Or maybe even in your
01:37	own home , let's walk through an example so that
01:41	you can learn a little bit more about how designing
01:43	works . So I've spent some time looking around at
01:46	home at school and even while playing sports , thinking
01:50	about different problems that I can solve and I've encountered
01:53	many problems . Let me tell you about the one
01:55	that I want to try to tackle right now .
01:57	So my favorite sport is valuable and when you're by
02:00	yourself it's pretty difficult to practice your skills alone .
02:04	So I wish that there was something that could help
02:06	you practice , you don't have anybody else around now
02:10	that we have a problem to solve . Let's start
02:12	brainstorming different solutions to that problem , brainstorming is an
02:18	incredibly important step in the engineering design process . If
02:23	you can think of multiple ways to solve a problem
02:25	, then you have a good chance of finding a
02:27	really good solution , so let's get to it .
02:31	Yeah . Yeah . Mhm . Yeah . Mhm .
02:39	Yes . Yeah , I've brainstormed many solutions to this
02:48	problem , including services that help you find other people
02:51	to practice with and find a coach to help you
02:53	practice . But I've also explored devices that will launch
02:57	a volleyball . You can then practice with three interesting
03:00	ideas that came up with include a kicking device to
03:03	launch a ball , a slingshot device and a pitching
03:08	machine , volley ball launcher . Now that I've picked
03:11	an idea that I want to explore further , the
03:13	next thing an engineer will typically do is make quick
03:16	prototypes to figure out more details about their solution .
03:20	Quick prototypes are useful because they don't invest a lot
03:23	of time or money and they keep things flexible so
03:27	that you can explore other solutions as well . What
03:30	I have here is a prototype made of cardboard that's
03:33	going to help me explore the kickball volleyball launder solution
03:37	. So it's basically just a cardboard structure with a
03:41	hammer that's going to act as the kicking force for
03:45	launching the ball up into the air . So after
03:48	you major models , the next important step is to
03:50	test them out that way , you can figure out
03:53	a little bit more about where your project should go
03:56	. Some important questions that you hope your model alliance
03:59	, there are things like does my idea even work
04:02	, don't need to talk to users some more .
04:05	Is it worthwhile to make a more refined , more
04:08	expensive and more time consuming prototype ? Those are the
04:11	kind of things that you hope a good model will
04:13	answer . So to test this one out , I've
04:15	gotten into a room that's got a little bit higher
04:17	ceilings so we can see what this thing can do
04:20	. Mhm . Yeah . Yeah . Yeah . Mhm
04:40	. So even though that was a lot of fun
04:41	, we actually learned a lot from this prototype ,
04:45	even though it wasn't that expensive or durable . One
04:48	thing that I noticed is that it's kind of difficult
04:50	to get the hammer to impart some momentum on the
04:52	ball and launch it up into the air . Another
04:55	thing that I noticed is that the ramp kind of
04:58	has to be designed pretty well , otherwise , if
05:00	the ball hits it , it's not gonna get launched
05:02	up into the air . Finally , another thing I
05:05	noticed about this idea is that by design it's not
05:08	really that portable because it's dependent I'm lugging around a
05:12	big heavyweight . So that could be a problem if
05:14	you want to take this thing out into a valuable
05:16	in that based on the things that I've learned ,
05:19	I've actually decided to switch from a kickball launching method
05:23	to a slingshot method . Remember how I mentioned that
05:26	? You don't always get it right the first time
05:27	through , because this video is a little bit short
05:32	, I don't have time to go through another model
05:34	at this level . So we're gonna skip ahead to
05:36	a more refined prototype . Okay , so here's our
05:39	more fine prototype , It's made of wood , so
05:41	it's a bit more durable than the last one .
05:43	And it's gonna help us find out a little bit
05:45	more about the sling stock solution . So the way
05:48	that this prototype works is that these elastic bands up
05:51	here will act as the slingshot with these two posts
05:55	, and this hook is going to connect to a
05:56	pin that goes through these holes right down here .
06:00	Then when the pin gets removed , the boss can
06:02	get launched from this funnel . So let's see how
06:06	well it works . Mhm . Mhm . Yeah .
06:15	Mhm . Mhm . Uh huh . So even though
06:23	this prototype worked , am I done ? Absolutely not
06:27	. There's still a lot more to do . I
06:29	could do stuff like improve the model by talking to
06:32	users and see if it actually meets their needs .
06:35	I can make it a little bit more user friendly
06:37	and easier to use . I could add more features
06:41	, something like a ball feeder so that you can
06:43	have multiple balls and then it launches them one at
06:46	a time . There's still plenty of things to do
06:48	. Keep in mind that the design process is actually
06:51	an iterative thing . So you go through it over
06:53	and over again until you arrive at something that's ready
06:56	to go to market . I hope you learned a
06:58	bit about the design process and you hope to go
07:01	out there and design something yourself . Okay , so
07:05	let's recap the process we took , we made an
07:07	observation that it's difficult to practice valuable by yourself .
07:11	We brainstorm solutions to that problem and we compared ideas
07:15	to pick our favourite one . We made prototypes to
07:19	test those solutions and then we had to repeat some
07:22	of those steps in order to find even better solutions
07:26	. That's how he came up with a way to
07:27	solve the problem of it being difficult to practice valuable
07:30	on your own . Yeah . Yeah . Yeah .
07:47	Mm .
