    Cafe Del Mar /plywood Relax Chair

    a ) Bent 3/4" plywood won't splay under a normal person's weight. b ) Who says it's for a commercial environment?

    Wow, I'm impressed by the quick turnaround, and also your willingness to address constructive criticism. The new design is definitely way easier to manufacture, and still has a sleek look. However! I feel like you've gone too far in the opposite direction, and are missing out a few simple and inexpensive processes that could retain a lot of the flair of the original design. The colour/texture contrast was one of the most interesting parts of the original concept, and you could easily keep that by simply adding a layer of white material to the final outside ply of the laminate. And you could keep the black, contoured tub seat with an injection moulded part that would attach to those brackets instead of the new planar design that is less exciting. You can also play with visual tricks on planar curves to make them look like compound curves. For instance, if the outer edge of the main plywood profile was cut with an arc instead of a straight line, it'll look quite interesting when it's bent into a semi-circle. In any case, good progress! How are you enjoying Humber, by the way? (I graduated from there 3 years ago)

    Kula (Sphere) Chair

    Can you use filled thermoplastics for rotomoulding? I know the Panton chair was prototyped in glass-reinforced polyester, but was subsequently manufacturing of injection-moulded ASA (like ABS). Basically what it comes down to is, this chair will never be inexpensive. But you probably knew that already.

    If you're rotomoulding it, you wouldn't need to do any post-forming process to remove that material, the blue part would simply be another mould (or two that joined at the middle, to accommodate for draft angles). The advantage of rotomoulding is that you can make your mould of many different parts. Downside is that it's less consistent than other plastic forming methods, and your cycle times are way, way slower. Also, you'll need to some generous fillets on the corners or else you'll likely end up with all kinds of webbing or voids, since the legs are fairly long relative to their cross-section. You could maintain the sharp angle by incoroporating that into the design of the tub part that inserts into the main body. In general though, that doesn't doesn't seem to easily lend itself to most manufacturing processes that are either simple or cheap. But hey, thinking about this kind of stuff is at least half the fun of design (or maybe I'm just a huge dork).

    Trolley Design

    A few things to consider: 1) Not really related to design, as much as presentation, but always make sure you turn on Perspective when you're doing renderings. Isometric views look really unnatural (possibly also where the 'engineer-y looking' comment came from) 2) Am I right in assuming that the internal mechanism in your tubes is a way to lock the the racks once they're in position (i.e. turn the knob and the two pegs lock into matching holes?) If so, it looks like a slightly cumbersome and overly complicated way to go about it. The knob is very round which would make turning it difficult if there's much load on the racks or friction in the system. Maybe make it a flat knob, more like the side one, but solid - this would also make the locked/unlocked position obvious. It also requires the user to make sure they find the right position for the rack to be in so that they can lock the pegs - do they need to hold the rack there, making it a two-handed operation? Could you make it spring-loaded so that the pegs automatically click into the holes when the rack is in the right position, and then they only need to turn the knob to compress the springs again when folding it? 3) There are an awful lot of small moving parts for something that needs to relatively cheap and bulletproof. Can you simplify the mechanisms? Maybe you've already thought about this and just haven't explained it here, but there do seem to be a few little ergonomic, usability, and manufacturing niggles here and there. I do like the attention to detail, though. You're clearly thinking.

    Attributes Of Sporty Product ?

    HA HA. Nearly wet myself there Buff Ditto for me. In the words of Mike folks - Just Do It! Don't try to analyse it to death. I have no idea what makes a sporty product, as sports are so diverse and in many cases defined by rules and regulations. Very true indeed. Flashy colours and dynamic lines may fit to some products, tear-and-wear issues be of interest for other products only. It's virtually impossible to give an exhaustive and general definition. Would you be able to say what makes a product classy for instance? Why, crisp edges and piano black finish, of course!
  7. Your perspective is off, and the hyper-rendered style makes the cartoonish proportions really pop out. Why don't you hold off on the rendering for now and just post a bunch of line sketches in proper perspective so that you can polish the fundamentals before diving in on the deep end?

    Clearly you know nothing about modern diesel engines.

    My Principles Of Car Design.

    Yikes. That seems awfully methodical. I just sketched a lot.

    A Full Hubless Bicycle

    I take it some of those details are: how on earth to make a practical hubless wheel? It recently took a team of Yale mechancial engineering students to make one that actually works, and it's neither light, nor efficient, nor practical. Very cool that you actually prototyped your frame, though. If you can make it work, you'll have yourself a pretty nifty custom bike.

    Mclaren Perfume Bottle Design

    To be honest, neither the form nor the renderings are especially appealing. Did you do any sketches first, or was this just a chance to get your feet wet in Solidworks? Also, even with no other changes, your renderings will instantly be much better by turning on perspective. Really, really important.
  12. I moved downtown, got a rewarding full-time job, lived it up for the summer and fall, then took off for 7 months to backpack in East Africa, Southeast Asia, and British Columbia before moving back home and picking up where I left off. Worked out pretty well...

    Gm En-v Concept's

    Personally, I like the idea. But maybe that's not surprising, since I designed something shockingly similar 3 years ago, hahaha.

    Final Year Project

    It really helps if it's something you're passionate about, too. If you don't love your thesis, you're going to hate your life when you're spending 26 hour days working on it. And largely I agree with Cyberdemon - your project will be much more compelling if you're dealing with a market pull. There are a lot of amazing technologies waiting for the perfect problem. Better off identifying the problem and finding the appropriate technology.
  15. Personally, I would trawl the used tablet PC market on eBay. About 3 years ago I bought a Toshiba R15 for ~$600 USD, and while it no longer works on battery power, it's been a fantastic tool. It's my only laptop, so I appreciate the portable form factor, but if you're primarily looking for a tool for sketching on the go, the Motion LE1700 slate tablet is probably your best bet. Compact (high quality 12.1" screen) and light, but it has a modern processor (Core 2 Duo). It won't be super fast, but for sketching it should be more than adequate.
