Parametric 3D Industrial Design

Hi,

To give you some guiadances (until today 02/05/2016 at 18:00):
We like the idea of Advanges about how the four pieces fit together. And also we like to say that the idea of Albertus Putra about how he solved the problem of the necessary length for the piece that should be into the sand while keeping it small for carrying it to the beach (it is easy to transport when this piece is folded)

Also use magnets could be another alternative

Regards

Dear Alvaro,
I really apologize for uploading three equal projects in a row, something was wrong with the page or my internet connection. Sorry again!

Considering that my design was not rejected, I will try to do a revision with emphasis on aesthetics. Hopefully I have have some thing for that later this week.

As for wind force considerations, it's common practice to not use such towel retainers while on a beach. It seems to me that the majority of forces imparted on this device would be those that come from rolling, sitting, or laying on the towel. The act of laying on the towel will reduce the influence of wind force and confine it to the very corners of the towel.

Huge sorry

Hi Advandes,
20 Miles is very very hudges ....;)

...and that's just the holding force required for the blanket. The force exerted on the device in the sand is a totally different dynamic. I can tell you without getting into all the math that to hold down your device in the sand with an upward wind force of 1.6 pounds, you will need to hold down 32 cubic inches of sand. That is an area equal to 2"x2"x8" deep. With a force a 90 deg or perpendicular to your device, you can cut the volume of sand in half, but I wouldn't...LOL... good luck!

Here is some information that may help the designers: Your device must be able to hold down the "beach blanket" that has a wind force exerting on it. For a basic calculation you can use wind speed multiplied by itself and then multiplied by .004. This will give you Pounds per square feet of force. For example: a wind speed of 20 miles per hour on a single square foot of area will require a holding force equal to 1.6 lbs. If your device can hold an object in mid air that weighs 1.6 lbs then maybe it will function properly. Although you better figure on either more wind or a larger area of force. Some of the designs look like they may work, but in my opinion many will not. I certainly wouldn't want to waste my money on something that doesn't work....Good luck!

Hi Reda,

https://www.cadcrowd.com/designs/large/1286_1453729433.jpg related to that i would like the "pin" can be easy to transport. Maybe as we need 4 pin, al of them could be connected in a cube or something like that for example

Related to the money, you can be sure that if the result satisfies us, we are willing to pay more

Adam, Reda,

sorry for the misunderstanding. You are correct, i do not want to exclude any designers. So everyone can participate!!

Regards

Adam,
this is not a private contest is open so I participate I worked for 3 or 4 hours on this project with my first 2 entries ..... I invested myself in there

Alvaro, would it be possible for you to go through and rate the designs? This helps us see what direction you are leaning towards. If you rate my design with a one star then I know not to bother improving upon it. It will benefit you in the end.. Thanks, Aaron

Alvaro, thank you for returning.

I'm ok with you excluding me (I don't know how the others feel) from your contest, but you are also excluding many other designers who did not submit to your challenge.
There are many designers within Cadcrowd who will not even participate to payment pending contests who have great ideas. Just something for you to consider.
If I offended you, I am sorry, but we get a lot of payment pending "post and runs" here, and everything you see is many hours of work. I hope you will accept my apology and allow the entire community to participate. I will stay out as you wish. - Adam

Hi Alvaro,

Thank you for considering us. We will try our best to submit a design which will satisfy all your requirements.

Best regards,
STL

I DO NOT UNDERSTAND ! WE CAN NOT PARTICIPATE ?

Hi Alvaro,
Iwant For your opignon ?

Hi,

I have reopened the proyect again in order to improve the desings. I Also prepaid to ensure the quality. Please, we would like to have a simple and funtional design but with a stetic and easy to transport point of view

Regards

Adam,
I remain optimistic towards this company and also cadcrowd

HI Adam, thank you for your support, it would be nice if they decide to pay quickly;)

i meant,...ending it at entry twenty-nine, the buyer bails with no fines:)

ending it at is really sketchy....
