Simplicity is key. As will need to be able to produce cheaply in large volumes.

MUST BE MASS PRODUCEABLE for cost in the region of $1-2.
Fitness for task combined with simplicity of design.

#4 Biodegradable pooper scooper by Bethanie
Compact pooper scooper, made of recycled cardboard.
String/cord is placed through holes, to pull 'box together', and scoop up dog waste. It can be carried via the string handles at top until a dog waste bin in found.
Box can be constructed with no cut and paste, tabs can be developed.

#18 Cardboardpoopholder by Ram Mohan Kartha
I have designed a poop holder that is make from a single piece of card board that can be folded and made functional by the customer itself. How it can be made is shown in the pdf file.

#19 Poopholder2 by Ram Mohan Kartha
I made this design considering quality as well as easier productivity, could be made by using paper or card board. The dimensions i have given are based on cardboard of thickness 1 mm. The advantage is that it could be made from a single piece of cardboard making your need of producing it in 1-2 $ possible. It needs sticking tape at 2 positions that also have bee shown in the pdf file provided. I can upload the orginal model file in any format if you need
Hope you will like my work ....Thank you

#20 poo bag by DaBu
This is a model I created myself from a A4 sheet of cardboard and a piece of rope. I thought that this is the only way to approach your problem: a 3d model wouldn't be as convincing. If you think I might have something here (if you like the design) I can work on it to improve functionality (dimensions, ease of operating, etc ..) and i'll provide you the CAD drawing for cutout and crease.

can it be a fusion of plastic and card board where the poop is collected in the cardboard part and only that part is thrown away after use. The plastic part is used again.....????

Hi Jnatzic

Would be a one-time product

>Bio-Degradeable is important...why I think Cardboard / paper best.

>Easy to assemble...perhaps sold 'collapsed'. And user 'pops' open to use. easier to build / transport
>I think it is important that it is not too large when assembled and used, as users will want to throw away in bins made for dog droppings (they are not that large)
>Needs to be reasonable 'air tight' so doesn't smell too much on the way to the dustbin.
>I was imagining something that maybe had a cardboard box / tube with two cardboard handles that could be dropped over dropping, then the handles pulled to close bottom of box and scoop at the same time.
>But maybe that might be too complex too design?
>I will be guided by you.

I feel the crux of this project is to get a really functional design that is not too complex to mass-produce at around $1

Will this be a one-time use tool or will it include doggy bags or something that makes it reusable?

shop mock up
HI i need few slides on a mockup for a shop front i'm opening. I need to have 3 main area, On the front counter, bit of space on the left, a hot food display with the GN 1/3 total 6, followed by a hot grill plate around 65/60 followed by cool display for sald ingredient around 9 1/3 gn, so total around 1.1. mtr.

I have attached photo of the shop today, We need to modify the shop name from Grill and go to "italian street food store, i attache the brand for porpoise. a drawing with the actual measures of the shop.

Digital LCD Name Tag for wine glass
We are developing a digital “Name Tag” (LCD screen) for wine glasses that will communicate with a mobile app. so people will be able to communicate with the tag via their smartphone and find their glass in case they can’t tell which wine glass is theirs...etc. We are looking for few design concept options for a prototype 3D design that we will print.

iPhone/Android Accessory Design Enhancement
This consumer product is an accessory that provides enhanced usability to mobile phones and tablets. The latest design of our "Band" is two parts: 1. Round Base that attaches to the back of the phone (made from a low-friction polymer like polyethylene) 2. A "band" that overlaps with the Round Base (1) and rotates/spins around it. (made from polyethylene over-molded with rubber to provide elasticity to the top band part) The rubber part of the band elongates so that an individual's finger can be placed underneath the band and above the base. The elasticity part is important so it can accommodate different finger sizes. The product allows users to hold the phone more securely. Our current challenge is the design of the "Band" (2). This is where we need the help. As shown in the attached STL file for the Band, there are two circles on either side of the flap that holds the finger down. These circle were put there to provide some added elasticity to the rubber piece. While it does functionally work well, the current design does not look durable or very elegant. We'd like to rethink the band design to make it look incredibly user-friendly, allowing the band to stretch upright to accommodate different finger sizes, while being functionally superior to the current design. Designer will need to provide STL files for my prototyping company to be able to work with.
Hi all, thanks for checking out my contest! I am involved with a company that is looking to receive some entries for a "prototype" electric unicycle. If you aren't familiar let me give you a brief background. Remember the hoverboards last xmas?? The electric unicycle works on essentially the same principle (upside down pendulum theory) to achieve self balancing capability. The current offerings on the market just don't cut it, the plastics are basically thrown together around the requirements of a build, rather than incorporating the necessary components into the design for a smooth finish. I would like the final product to be somewhat futuristic/prototypish looking, maybe a bit sporty. You can get a feeling for whats out there by doing a google search for "electric unicycle". Integral to the design there are 3 requirements. 1.) Obviously the plastic fairing will need to have a cavity for the wheel, but in addition, it will need to subtly include a space for lipo batteries, (doesnt have to be in any particular shape however), and also must include spot for a pcb control board. Both of these items arent excessively large, the PCB is about 4X3 inches and the batteries are about 5X5X1 (but can be reconfigured). 2.) I would also like to incorporate into my design a headlight, and a tail light if possible, but most concerned with head light. Would also like to leave the option open to include small bluetooth speakers, however these would not take very much space at all. 3.) Finally, this design will need to have a retractable handle for balance when getting on/off.
