sketching • Re: Looking to improve

Really digging that petrol station edition coffee maker. A few refinements to think about:

1) could the shape of the drip tray echo the upside down us shape of the flat surface it fits on?
2) does that orange thing on the side need to be there under the cup dispenser? Feels superfluous and would be an extra part ($$$)

These are some of the things I think about when I look at sketches. I might do an overlay of that one if you are cool with it.

software and technology • Re: Alias modeling question

Gotta say that zBrush and Modo are right now some of the most accessible and powerful SubD modelers out right now add in GoZ and the two softwares talk to each other so designs update. zBrush definitely has some vooodooo magic under the under hood that requires keeping track of high polygon geometries that need to brought down to something reasonable for conversion to CAD (Pro/e, SW, IV…etc). Also, and this is pretty unique in industry, Modo’s plug in Power SubD allows for pre-processing of the geometry so that edges can be set up when converting to NURBS. Normally a mesh, be it composed of tri’s or quads, can get a quilted NURBS patch that is very “disorganized” which really creates challenges for say creating parting lines for molds or adding draft.

transportation • Re: Tesla Model 3, opinions/discussion

I don’t get the Viper comment at all.

I think the truck is very successful visually. It looks like a Tesla, it looks electric. A lot of attention has been paid to aero. The wrap around greenhouse is very impressive. that is something that is very easy to draw but very hard to execute. Notice how the a pillar is completely masked behind the glass ant the transitions look fairly flush. Last time I was up there they said they were bringing a few glass experts in house… makes sense. If you are going to do this kind of simple but difficult to execute work you need the people with the knowledge working with the design team.

Architecture’s UX Problem

Research shows people don’t understand how to use high-performance buildings. Does architecture need a UX breakthrough?

Julia K. Day remembers the moment she got interested in understanding how people use architecture. Day, who is now an assistant professor in Washington State University’s School of Design and Construction, was a design student studying a new high-performance building in Spokane, Washington. The building had an interface designed to let people know when it was environmentally ideal to open the windows rather than use the A/C. When the conditions was right, a green light would come on–supposedly letting people know they should open their windows.

This reversible fabric is like personal heat and A/C

A reversible fabric keeps skin a comfortable temperature whatever the weather—and could save energy by keeping us away from the thermostat.

As reported in Science Advances, the double-sided fabric is based on the same material as everyday kitchen wrap and can offer warmth or cooling depending on which side faces out.

“Why do you need to cool and heat the whole building? Why don’t you cool and heat individual people?”

“Why do you need to cool and heat the whole building? Why don’t you cool and heat individual people?” says Yi Cui, professor of materials science and engineering at Stanford University, who thought if people could be more comfortable in a range of temperatures, they could save energy on air conditioning and central heating.

Thirteen percent of all of the energy consumed in the United States is due to indoor temperature control. But for every 1 degree Celsius (1.8 degrees Fahrenheit) that a thermostat is turned down, a building can save a whopping 10 percent of its heating energy—and the reverse is true for cooling. So adjusting temperature controls by just a few degrees could have major effects on energy consumption.

Our bodies have all sorts of ways to control our temperature. When it’s cold, the hairs in our skin stand out to trap warm air. Eventually, we may start shivering to produce more radiant heat in our muscles.

When it’s hot, we release heat as infrared radiation from our skin, and if we’re still warm we start to sweat. Water evaporating away from our bodies carries a large amount of heat with it.

But those mechanisms only help within a few degrees. Get outside the temperature range to which our bodies can adapt, and we reach for the dial on the heating or air conditioning.

In 2016, Cui’s team came up with a first step toward a solution: fabric that allowed the body’s heat to pass through, cooling the skin. Although the inspiration came from transparent, water-impermeable kitchen wrap, the new material was opaque, breathable, and retained its ability to shuttle infrared radiation away from the body.

“Right around when we figured out cooling, then came the question: Can you do heating?”

Compared to a cotton sample, the fabric kept artificial skin 2 C cooler in a laboratory test—possibly enough to stop a person from ever reaching for a fan or the building thermostat. The team’s first textile could save a building full of workers 20 to 30 percent of their total energy budget.

“Right around when we figured out cooling, then came the question: Can you do heating?” says postdoctoral fellow Po-Chun Hsu, who is the new paper’s first author. It was a particularly chilly winter, and he was headed to a conference in Minneapolis with a carry-on bag full of coats. Could he create an article of clothing that would serve him in a crowded warm conference room as well as on the frosty street?

Hsu realized that controlling radiation could work both ways. He stacked two layers of material with different abilities to release heat energy, and then sandwiched them between layers of the cooling polyethylene.

On one side, a copper coating traps heat between a polyethylene layer and the skin; on the other, a carbon coating releases heat under another layer of polyethylene. Worn with the copper layer facing out, the material traps heat and warms the skin on cool days. With the carbon layer facing out, it releases heat, keeping the wearer cool.

‘Smart fabric’ could store passcodes or I.D. in clothes

Combined, the sandwiched material can increase a person’s range of comfortable temperatures over 10 F—and the potential range could be much larger—closer to 25 F. With people wearing that kind of textile, buildings in some climates might never need air conditioning or central heating at all.

But the white-colored fabric isn’t quite wearable yet.

Other possible applications include clothing with medical devices—and even entertainment—printed right into the fabric.

“Ideally, when we get to the stuff you want to wear on skin, we’ll need to make it into a fiber woven structure,” Cui says. Woven textiles are stronger, more elastic, more comfortable, and look much more like typical clothing. But good news: They’ve already started testing to make sure the fabric will be machine washable.

“From my perspective, this work really highlights the significant opportunities in combining thermal engineering concepts with nanophotonic structures for creating novel functionalities,” says Shanhui Fan, a professor of electrical engineering.

The team’s ambitions don’t stop there. Other possible applications include clothing with medical devices—and even entertainment—printed right into the fabric.

“I think we are only seeing the beginning of many creative ideas that can come out of such combinations,” Fan says.

The Advanced Research Projects Agency–Energy, US Department of Energy funded the work.

general design discussion • Re: We have $10,000 – what should we buy?

Yes, an injection molding machine seems a bit overkill. Agree with Cyberdemon on how advanced injection molding is now a days that a simple machine without a teacher would not be a good investment for the school.

Also, if injection molding is of interest why not create simple RTV molds. Teaches you the basics of molding without the expense. Back in the day we used to have to take Metals, Woods and Plastics classes separately plus Design Methodology and Production Techniques….now it is all combined into one or two model making classes.

The electronics kit may be nice but also a bit misleading and I’m afraid students may focus more on the coding or EE design that they’ll put design second. Besides, if showing how something works in real life or having an working prototype is the goal, you can probably buy a new or used XYZ, open it up and use the same components for your new XYZ. Then you can use your school’s filament 3D printer to print your beautifully designed housing.

Maybe use the 10K for a sponsored project in AI? Have the class design a robot that solves a specific need or helps somebody perform a task better. Use the 10K for materials, prints or guest speakers on AI?

general design discussion • Re: Branding Help


I really appreciate your thoughts! Yes, ‘Founding’ is a good name to me. If you are still in need of selecting a brand and domain name, then here are few things that you should check when considering a domain name:

1. User Perspective: Your brand/domain name needs to be easy to read, easy to remember, and easy to say.

2. Brand Perspective: It is better to have the brand name as domain name. The domain needs the right extension and uniqueness.

3. SEO Perspective:

If you are selecting a brand name that doesn’t describe your products at all, then go with it as long as it is unique.
If you selecting or seeking a name that will focus on products too with the intent of unique branding then you should care about relevance and search terms (only seed keywords like Brandname+shoes).
It is not good to use EMD. also, you can consult an SEO company (like https://qodemedia.com or any other qualified SEO companies) if you need to know more SEO for selecting an SEO friendly domains. My recommendation is to go with just a unique brand name.

4. Legal Perspective- It is a wise step if you think about the copyright & trademark at the beginning. It will secure your future steps in branding and networking. Just go to the sites that provide data on exists trademarks and copyright information like copyright[.]gov and others and confirm you are using a unique brand name.
