    I think anyone would need much more info eg. end use, budget, mfg volumes etc...to help. But just off the cuff; could you stamp slots in the sides (two for each wire end) and slide the wire through the slots? then lock bent ends of the wire it into a hole adjacent the slots? If you do not want to stamp slots into the surface, depending on the type of plastic you could also weld some retainer loops onto the bottom and slide the wire through them..... maybe two loops for each wire end.

    Hello Erich, Thank you very much for the reply. I want know when calculating the power of motor it must contain both force acceleration force + force again friction or any other method. I have argue in calculation force again the friction. in this case if i want to use normal rolling friction or is there any other value for static rolling friction? BR, Udaya.

    Dana, In general I would agree with you - I think that it's one of the few effective yardsticks that a requester of advice can use to judge the quality of advice being proffered. But I do have one caveat to add, and that is for people offering advice when their first language isn't English. As a case in point, srdfmc made the pertinent point that Dassult Systems has done basically nothing to clamp down on piracy, and that in a competitive and probably very low margin environment you will struggle as a legitimate owner to recover the initial purchase costs. So I do think it's also important to view and evaluate the information intended by a post that is written by someone for whom English is not a first language, but in general, I concur.

    Hi Abilash, With the pitch you have indicated (14mm) that is going to be a very thin pawl - which I think may give you a number of issues. (The pawls and levelwinds I have designed - have typically been for spooling cables down to a diameter of 16mm). It is unclear from your posting what sort of line pull you are talking about - but assuming it is not massive - then my suggestion would be to approach the problem slightly differently and do one of the following:- 1. Consider using a small fleet angle - see the document below for an explanation of this - and you will not need a levelwind bar full stop. You might like to go and have a look at a telescopic crane - and you will see that they do not have any spooling device - they just rely on the very small fleet angle - and the drum self spools. http://www.bridon.com/usa/x/download...et%20angle.pdf 2.Consider driving an ordinary ISO trapezoidal lead screw (clockwise and anti-clockwise) which thus moves a nut onto which you have...

    Search the web on "steel wheel rolling resistance" Calculate torque required to accelerate the cart. Make estimates on inefficiencies in gear boxes. These should point you in a productive direction. The rest of the project is up to you.

    It depends on what kind of work you'll be doing. SWX (like all other parametric modelers) is great for iterative design; making lots of minor dimensional changes is very easy. Also lots of other people use it. However, parametric modelers can be very cumbersome for making large design changes, when you find that your base sketch the entire design is based on has to be changed. In this case, a direct modeler like Creo (which I've never used) or KeyCreator (which I've used for years) can be a lot faster, especially if you have lots of freeform surfaces. Direct modelers are also much better at working with imported data, which can be important for job shops and others who have to work with customer or vendor data. Parametric modelers generally have limited capability to work with anything but their own proprietary format. That said, the "best" CAD system for you may be the one you or your engineers are most familiar with. K.I.S.S., yes... I've learned that the quality of...

    Hi,'Ace' I'm going to break my own rule and reply to the type of comment that I said I wouldn't reply to in the original post, and I'm doing so solely because I believe your advice and comment is sincerely well intentioned, if slightly off the mark. I assure you that I'm fully aware of the decal function in SW - I've been using it for the past 15 years. That doesn't change the simple fact that I would still have to recreate the same drawing as before and then replicate it with a linear pattern to form the decal. It's also pertinent to note that a decal will not provide me with the surfaces required to generate accurate ray traces for rendering.

    Solidworks has decal function that will put an appearance finish on a surface. You may have to make your own decal to get the look you want, but it should work. Look for surface finishes in the appearance property manager. AceEngineer

    Thanks for the question. Venting and placement of the battery allows for a similar environment as carry the pills in a plastic bottle.

    Don't know if I missed something but what about the heat that can be generated by the battery in close contact to the pills. is that safe enough ? And what about the gas fumes ? IMOHO, you should go wireless.

    I'm a long time SW user, and one that uses most of the wonderful functionality of the program, from boundary surfacing to sheet metal. In general I'm a big fan of the program, but sometimes.... If anyone wants to waste a good couple of hours, or if any lecturer at a drafting academy wishes to pointlessly occupy their students on a day that they would rather visit the local pub, then simply try to recreate a 'engine turning' finish on a part (otherwise known as Damascening). I had such a requirement today, and it almost drove me up the wall. If you're not sure what I'm referring to, then Google 'Images of engine turning'. I had the requirement today of creating such a cosmetic appearance on a part - easy stuff, right? Create a sketch with multiple concentric contours and then a tiny cut extrude to simulate all the brush marks. No - simply because SW doesn't allow you to effectively vary the instances of a linear pattern when mirrored or repeated in a different axis. I know...

    Everyone sues everyone for everything... But progress still happens. Automated pill dispensing is used today in hospitals and there are many in-home units available. But none of them have the computer power of the Smartphone, nor the portability. Nothing in this world is perfect, but some things can make help solve major problems. Your legal argument could be used against almost any device or service and yet new devices and services are offered every day. I enjoyed our back and forth, good luck and have a safe life.........

    Hi, As a final note, when in some idle conversation with my wife today, I brought up your concept. My wife holds a Degree in Care Management, and she was frankly horrified by the prospect of automated medication dispensing - she raised some very valid points, not least of which is that at some point along the line, you ARE going to get sued when something goes wrong. And so will the smart phone manufacturer when the battery dies, as will the mobile network operator when the network is down. The list is almost endless and will probably result in lawsuits being kicked down the road to every single component manufacturer, until they get kicked back up the road again to the person that is ultimately responsible - the designer... I personally detest the current legalistic culture that we find ourselves in, but I'm afraid that it's a sad reality of our modern society.

    No problem, the feedback is great. I understand your points and agree they are not simple issues. But non-compliance and counterfeit meds cost hundreds of billions of dollars and lives every year. Again I don't think our device is the answer to everything, but it offers the integration of a Smartphone computer to verify, record, notify and dispense pills. Following your position, nothing can change we just have to except the losses caused by these issues. Call me an optomist, but I think progress results in change every day. Not to many years ago, we could not communicate like this..

    Hi, I have to say that whilst I admire your commitment to the device, I have some doubts about the realistic philosophy that underpins your Company's vision. If you intend to attempt to get ANY pharmaceutical Company to standardise their medication to suit your device, then firstly I would urgently ask you to re-visit the post from Erich - there are innumerable complications involved with such a move. Have you taken into consideration the fact that there is a standard classification and identification system that allows paramedics and doctors to quickly and easily identify pill overdoses? This is comprised of the three primary factors of shape, colour and size. They simply cannot be reliant upon miniscule markings upon the surface of the pill, as these can be quickly eaten away by digestive stomach acids, so in the event of a overdose stomach pump... And secondly, I would urge you to give consideration to the fact that many medications are required to be of slow release format -...

    K.I.S.S. I appreciate your thoughts. It’s good to get all opinions. So now let me try and address your thoughts. First in regards to the countless variety of pill shapes and sizes. Yes I have given this great thought and my feeling is that at least initially my device is best suited for the clinical trial environment. In these cases the pills could be designed for the device. Then if the device showed merit, other pills could be custom designed to fit the device. I don’t see the device as useful to the casual medication user, but more for people with chronic illness that required continued medication. The key to the device is not the mechanical components, but instead the integration of the Smartphone’s computer in the medication delivery process to combat the non-compliance and counterfeit problem. Second with regards to exposing your pills on your Smartphone. The prototype unit was designed to accommodate commercially available components. A production unit would use custom...

    Hi Intemed, I think that my gut feeling would be that you won't get a large take up on this product. If, as you state, there are many millions of smart phone owners out there who are reliant upon daily (and presumably vital) self administered medication, then I would be more inclined to set up a subscription based App that would allow their personal usage and requirements to be sent to them on the required basis - daily, three times per day etc., either through a text message or email. At least in this way you would also cover the non smart phone owners. And have you given a lot of thought to the bewilderingly large variety of shapes and sizes of tablets and capsules on the market? I was reluctantly forced to take one such pill a few weeks ago, and I have to say that I'm glad it wasn't a suppository... I think that at heart, human beings in general are reluctant to disclose any physical weakness, certainly the younger ones (although past a certain age, I think it becomes...

    Any other thoughts. How about what do you think about a pill dispenser attached to your Smartphone. The prototype in the video was produced with commercial components. In production it could be much thinner and smaller and the transparent parts would not be.
