F U S I ON D ESI G N Campbell, California, 10/12/16 We got a great opportunity to visit the Fusion Design office and play with their telepresence unit. I was impressed with how the unit moved around quickly and precisely, and I liked the feature it had of stopping before running into things.

Right off the bat I was struck with the software side of the unit. The controls were easy and user-friendly, but the interface was quite ugly and not very visually pleasing, which is a shame since that is one users entire side of interaction with the unit.

I did not find the design of the unit to be that appealing, although the finish and materials were nice. The only aesthetic element that I genuinely liked was the recharging station.

This particular model cost around fifteen thousand, which was way too much in my opinion. Yes, it was very cool that it could drive around, and yes everything seemed to be of good quality, but it did not look like it should cost more than $500.

One of the things I took away from our time at Fusion, interacting with the telepresence unit, is that if it is going to cost that much, it better have some damned good features.

AC O RN PRO DUCT D EVE LOPME NT Newark, California, 10/19/16 Our class was able to visit the home office of Acorn Product Development in Newark, California where we got a tour of their products and a presentation of their business.

The project Acorn highlighted was their robot, the Robotex Avatar Micro II (as pictured).

The robot’s purpose is to work in conjunction with SWAT teams and other law enforcement units as a way to reduce casualties. The unit is a life saving device in that is does things like breaching or bomb disposal that are typically extremely dangerous.

Due to the rough environment it is operated in, it was fascinating to learn the rigorous user experience & manufacturing considerations that went into the robots design.

This research trip made me appreciate the amount of work that goes into designing something that people’s lives literally depend upon.

T H E PROBLE M Current Telepresence Robot designs neglect the functions and aesthetics of a home market.

T HE G OAL Design a telepresence unit that fits seamlessly into the home, while incorporating functions that assist and improve everyday life.

CO N SI D E RATI ONS Some quick definitions: “Telepresence” - The idea of being visually present during communication.

“Robot” - A machine for completing tasks.

“Telepresence Robot” - A machine used to be visually present during communication.

EN V I R ONM E NT Designing it to blend into any environment through a use of natural materials like wood and glass. Although the unit would be large, at about 62” high and about 50 lbs, it would also be thin and could be against the wall easily so to not be in the way.

For the high volume, less expensive model, I will likely be using some for of plastic to reduce manufacturing costs, but we’ll get into all that later.

U N C A N NY VAL L E Y One thing to be careful of when designing a robot, is to not make it too human like.

You know how sometimes robots that look like humans are creepy? That’s called an uncanny valley. Robot that looks like square? Not creepy. Robot that looks like a robot wearing a human face? Creepy as hell. My goal is to design a telepresence robot that looks more like furniture, so that it blends into the home and doesn’t give everyone nightmares. Beep boop blorp.

P R I M A RY U S E The primary use would be people who want to be in closer, more personal contact with ones they communicate with regularly, but also get more out of the robot than just the telepresence. Ideally the unit would be used all day long from assisting with workflow to providing an entertainment platform.

FE AT U RE S Ideally this unit would feature full touch screen capabilities and see through glass so that it blends into your home (Or in the less expensive, high production model, a one way mirror with a tablet behind). Both would be running an android OS system that would function like a large tablet. The camera would be a iPhone unit, so very crisp resolution, and the speakers would be JBL to produce very good sound, for more than just video calling, but for music or movies too. The batteries in the base would allow the unit to be wireless, and the unit would be able to move around all types of floors due to the tread base.

MI S C .

Future Scenarios: One day this unit could replace TV's and tablets in the home.

Competitors: TV’s, tablets and other mobile devices that allow the user to engage in media and communicate visually with others.

- High volume goal for under $2k, like the price of a very nice television. 500k units.

- Low volume goal for about $25k - like a piece of functional art. 500 units.

As mentioned earlier, I’ll be designing two types of telepresence units. One low volume, one high volume.

It’s important to remember which one is which.

As a recap, in the last few pages we considered the personas for low and high volume, some early concepts, and then the components I selected. Using these components I came up with 20 initial directions for high and low volume.

For the rest of this book we'll be getting into details and specifics. We'll start by exploring some low-volume concepts using different manufacturing methods.

CO N C EPT / FORM E D Sheet metal: A press brake is a machine tool for bending sheet and plate material, most commonly sheet metal. It forms predetermined bends by clamping the work piece between a matching punch and die. Bending process.

CO N C E P T / AD D ITI VE Carbon fibers are usually combined with other materials to form a composite. When combined with a plastic resin and wound or molded it forms carbon-fiber-reinforced polymer (often referred to as carbon fiber) which has a very high strength-to-weight ratio, and is extremely rigid although somewhat brittle.

CO N C E P T / CAS TI NG Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term “sand casting� can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.

D F M A - D E SI G N FOR M A N U FACTURI NG & ASSE MBLY DFMA is an essential process that combines “Design for Manufacturing” and “Design for Assembly” to create a product that is easily made and built. By designing a product with DFMA in mind, the smoother, more seamless process can help reduce overall costs and difficulties. I will be using these guidelines to refine my two designs.

R E DU C E PARTS Reducing the total parts is an efficient way to reduce costs on both the manufacturing and assembly side. This can be as simple as less inventory and shipping to something as complex as designing the part to be made in a single mold, casting or injection.

MO DU L AR D E S IG N Modular parts assist in the manufacturing process because it can simplify processes like testing which can be costly, as well as design flexibility. Rather than redesigning entire units, the modules can be altered as needed, saving time and money.

STA NDA RD IZ AT IO N Utilizing standard components, also called “off the shelf� or OEM, can save manufacturing costs. Because these parts are made in such large quantities they are often quite inexpensive , they have had all the quality issues solved, and they are available in large quantities.

MU LT I -F U N CTIO N AL If a part can be used for more than one function, that is a cost saving opportunity. This can be as simple as a structural member of the product also doubling as a heat sink, or an element that can help guide a part into place.

MU LT I -U S E Some parts can have multiple uses across the same product, or even different products. These parts can reduce manufacturing costs by simply doing more than one thing. These parts become part of a family and follow set steps to increase assembly speed across a spectrum of products.

FA B R I C AT IO N Choosing a material and fabrication process that do not require as much finishing or detail work. If excess processes like painting are needed they can drive up part costs and slow down the overall production speed.

CON S I STE N C Y Utilizing the same fasteners across the design will safe part costs because manufacturers would be able to buy in bulk, as well as assembly costs because less tooling or stations would be needed, since the fasteners would all use the same bits. Self-tapping and chamfered screws are best for improving placement success.

TO P - DO W N AS S EMBLY If the part has to be rotated for every fastener or piece during the assembly process, it will slow things down significantly. This is why minimizing the assembly directions are so important. Ideally, things would be installed top-down, with the assistance of gravity and consistency.

FAC I L ITAT E IN S E RTI ON Also known as maximizing compliance, this process saves errors on the assembly side, by increasing the probability that the parts go where they are designed with limited interruptions. If done poorly, parts with poor compliance will get snagged or broken when being inserted into place.

MI NI M IZ E H AN D LI NG Much like the top-down assembly, minimizing the handling is an assembly opportunity. Rather than flipping parts around and struggling to connect things, a well designed product takes everything into account, and makes it so the overall handling is reduced, which saves time and money on the assembly.

C ONCLUS I ON If the manufacturing and assembly are taken into account during the design phase, there will be savings of time, errors and costs across the board.

LO W VOLUM E S E CO N DA RY PROCE SSE S I - BACK W I RI NG BAR II - CO M PONE NT HOUSI NG III - BA S E HOUS I NG

S E C O N DARY PROCE SS I Sand cast aluminum, for the rear of the telepresence unit. This would provide a housing for the electronic wiring going to and from the audio visual components up top and back down to the modules in the base. I am using this process because sand casting provides a great looking almost-rough piece when semi-finished. This aesthetic will match well with the wood of the body.

Sand mold is made creating a cavity inside based on an impressed mold of the desired form. Due to the consistency and fine grain of the sand very accurate details are possible, although draft and undercuts are still an important consideration.

Molten aluminum is poured into the holes, filling the cavities. The design must take into account the sprues and risers to ensure the molten metal flows evenly and that the final product does not have any gaps or weak areas.

Break away the sand mold after the metal has cooled. This reveals the unfinished form. The sand can be collected and re-used for future molds.

Finishing the form is important as every sand cast mold has sprues and risers where the aluminum was poured in and risen up. These can be removed and the bar finished. For this form it will be a little rough for a more natural aesthetic.

S E CO N DA RY PROCE SS I I Laser cut and bent sheet metal could be considered a two part process, but when done well it can be a seamless process. First the machine laser cuts out a “flat� design for the box and then the press brake is used to bend the sheet metal pattern into a 3-dimensional form. In the case of the telepresence unit it is a great process to make a housing for the internal components.

Designing the cut is an important step since the bending process is completely dependent on if the design in foldable. Many mockups are made to ensure the design is functional.

Laser cutting the part takes more or less time depending on the thickness of the sheet metal as well as the power of the machine. For a highvolume design turret punching would be a better process.

Bending the part into the final form is done using a press brake. This machine uses specific jigs to create angles in the sheet metal by applying force in one direction. Rounded forms are do-able but take more time.

Finishing the part involves grinding down edges, welding needed areas and even powder coating.

While some of these processes can be for aesthetic purposes, they also reduce the sharp edges.

SECONDARY PROCESS III CNC is a process that is perfect for the base because it allows for a lot of precise cuts to be made while still keeping the overall form complete. CNC for the base would take a lot of special tooling since the part is so large and requires so many different size bits.

However since this is the low volume design it would be acceptable for the price range.

Designing the CNC is important since the body has to house all the components tightly. This must also take into account the sheet metal component shape so they do not clash.

CNC cutting would involve many times to change the tools and bits but if the machine is fancy enough it can swap bits on the go to reduce the overall time and in the end save money.

Base CNC would have the final holes drilled in to accommodate the sheet metal component housing attachment. By doing screws instead of adhesive the parts could be removed for repair easier.

Finishing the inside of the CNC shape would involve some sanding but for the most part it would be done and ready for the install of components.

H IG H VOLUM E S E CO N DA RY PROCE SSE S I - RE AR F RAME II - BAS E PL ATE III - BU M PE R

S E C O N DARY PROCE SS I Injection molding, for the frame of the telepresence unit. This piece would support the mirror surface at front, while providing a way to get wires up top through the body.

This is a good process for high volume manufacturing. Since this would be a large piece the tooling would be expensive at first, but as long as it is produced at a large scale the tooling price margin becomes tiny.

Combining three pieces in the design would mean using a three part mold to account for undercuts and features This tooling would cost a lot, but be worth it for such a high volume injection mold.

Tooling the mold with precision is extremely important to the final design an appearance of the parts. The rear frame is the largest of the parts and would require the largest and most expensive tooling.

Snap fastening is an inexpensive and quick solution to connecting multiple parts for high volume designs. The choice for this design is a non-removable snap because this is supposed to be a “cheaper to just throw away� design...

Features of injection molding include sprues and ejector pin marks. Ribs are needed to strengthen the part and are built into the design along with draft angles.

S E CO N DA RY PROCE SS I I Compressed Molding is a great process for the base plate at the base of the unit. Due to the components and proximity to the floor, this needs to be protective as well as simple.

Compressed pressing takes heated plastic and using a die and tooling presses a form into place. This process is used for many high volume products since it is so simple and quick to form the parts.

Designing the skid plate is important since all the components need to fit tightly when fastened after the forming process. This must also take into account the snap fasten connections.

Details that would normally be done with a turret punch can be molded right into the form.

For example, the wheel slots and charge port openings.

Compressed molding the plastic involves high pressure to get a consistent form. This shallow design does not require the plastic stock to overstretch so it would not lose structural integrity.

Takes into account draft angles for release.

Fastening the skid plate to the die cast base simply uses snap fasteners from the upper molded unit to complete the base. This will be secure but nearly impossible to reopen once closed.

S E C O N DA RY PROCESS I I I Die casting is one of the most efficient high-volume metal manufacturing processes. In the design for this telepresence unit the weight has to be taken into account since the mirror is heavy and additional weight is needed at the base. The die cast metal would also add an additional aesthetic to the design that is otherwise plastic on the exterior.

The base / bumper adds needed weight for stability as well as a tougher surface than the injection molded plastic. Would be a ring around the base, surrounding the internal components.

Forming the part is done with a die-cast mold.

It operates similar to injection molding but with molten metal, in this case aluminum. Design incorporates 10 degree draft on all edges.

Finishing the die cast part involves sand blasting the part, but the majority of the texture comes from the mold itself. This ensures a constant texture across all the parts, while trying to replicate the roughness of the original design.

Fastening systems are molding into the part.

Specifically snap fits for the top housings and snap-in punch holes for the skid plate underneath.

Treated with a polyester-based coating to protect it from possible corrosion problems that might arise from being on the ground getting scratched or damp.

Hishimetal (MC# 4822-02) uses laminated stainless steel with polymer film faces. It offers high workability, allowing for high variability in structure through working processes like punching, forming or bending.

I chose this material because it’s price and durability make it the best choice. Especially the durability since it’s on the floor.

Picking the right manufacturer is an essential step of any good design.

This selection process begins at the design, and depending on the parts and pieces, points towards a specific manufacturing direction. On the next few pages we will be considering Process, Quality, Price, Capacity, and Geography, but before we look at those, here are some things to consider when picking a manufacturer:

1 . W H O YO U KNOW Done a project with a manufacturer before? Did it come out great?

Awesome, there you go. As you grow in the industry and meet people, personal relationships will become important and so will good work.

Often times the “good work� costs more up front but can save money in the long run.

2 . RE CO M M ENDATI ON New to a certain type of manufacturing? Ask a colleague who they use. Again, personal relationships in the industry can be very important.

3 . T RAD E S H OWS Trade shows can be a great way to meet manufacturers and develope relationships. The shows also provide a way to see their goods first hand, as opposed to word of mouth or through photos online. Pick up the parts, ask questions, and learn.

4 . M ANU FACTURE RS RE P Manufacturers representatives make it their business to know people. You can rely on their experience and connections if you need more options. An added bonus of these representatives is that they are free to use. Be nice though, they have feelings too.

5 . RE S E ARCH When all else fails, look it up. The internet is a great source, although it can lack a personal touch, as well as a physical touch for part quality etc. Thomas Guide is another research tool that can assist the manufacturer selection process.

To get a visual interpretation of the data I had to first make a spreadsheet, figure out how to make it work, and then figure out how to calculate margins and other fun things like that. Long story short it took a while and I pulled a lot of my hair out, BUT I did end up with some great data that I could use to graph.

It was through this graph that I was able to compare the Low and High volume telepresence units.

The Low Volume units are the more custom ones, which relied on less upfront tooling but more expensive labor and components. This resulted in a lower single unit cost, but once it got over 100 units, a much higher unit cost (about $12,000).

The High Volume units are the ones that would be sold in places like Target and require a mass production approach. Setting up the tooling would be expensive, which is why the single unit price was so steep.

Eventually though, due to low cost on components and labor, the High Volume units ended up costing much less once they got over 10,000 units.

Seeing the two costs side by side made much more sense and helped me visualize the market applications of each and the volumes required to make them viable.

As shown in the Low Volume data, a margin of 55% would be added to the total cost, making a unit price at 100 units about $24,000 As shown in the High Volume data, a margin of 45% would be added to the total cost, making a unit price at 100,000 units about $1,650

INTEGRATED: Cast Embossed/Debossed Laser Cut Texture Machined Two shot molding OTHER Grown Metal Stitching Embroidery Backlit Corroded

M ACHI NED Machining the brand onto the cast metal in this case simply means grinding down the rough gritty exterior until it’s flat, revealing the shiny solid metal below. This would provide a nice two toned contrast and really make the logo pop out.

CAS T Casting the branding along with the rest of the metal is a very integrated way to include branding. This branding method could provide a very seamless and simple look that would match the rest of the design while also not being another step in the manufacturing process. Must take into account draft angles.

I NL AY

S E L E CT I O N

Inlaying is a beautiful way to incorporate branding into a form. It involves the metal being milled out, and the wood cut to fit.

To do this right would require a specialized craftsman and would be quite expensive per unit. Because it would take a lot of skill and precision while providing a very unique look, I chose this for my low volume unit branding.

S TI CKER Stickers are a quick and easy way to apply branding to just about any surface. Issues can arise through time as stickers can peel or have their edges tattered. This solution is just not integrated enough for my liking.

PAD PRI NTE D Painting the logo on using the pad painting process can be a very inexpensive way to brand the unit. If done well the paint would not chip and could have a nice look to it, but it is still not integrated enough for my liking.

MOLD E D If the mold used to injection mold the part has the logo integrated, it can be an extremely inexpensive branding feature, especially as the number of units increases. Even better the logo is completely part of the product and will never peel off. I chose this method because it will be cheap, work well, and look great.
