Contest Ended, Winner(s) have been selected.
An alternative to picking up dog dropping with plastic bags.

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.
Don't Wants:
Complex designs, impossible to produce cheaply

Over simply designs that do not enclose droppings....or pick them up at distance of at least 3-4 inches from hand to droppings.

#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.

#7 Entry no.1 by PETER LAKATOS
Hello, This is my first entry in this contest.
Please see the attached pdf. and image file, and let me know what you think about it. The design is flexible and can be adapted to any suggestion you might have. I will keep thinking about new ideas to show you.
Thank you.

#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?

Leaside Project
I am building a new home and require innovative interior architectural design options ( kitchen, family room, living room and powder room) that will accommodate an exterior elevation that is already defined. One of the most important aspects to this assignment is the location of the interior foyer relative to the location of stairs that go up to the 2nd floor and down to the basement. The desired design of the foyer is to be defined in terms of its presence but not in a manner that it takes away from the interior space in a significant manner. Once a 1st floor layout is approved, the need to prepare a modern and eye catching interior design (with furniture, crown holding, tray ceilings, wainscotting, etc. ) with photo like renderings will be required. I have attached the exterior elevation (which is reversed to the actual location of the garage) but it provides a sense of the foyer location. I have also provided a PDF of the ground floor footprint that we have to work with. The dimensions of the foot print is fixed. This ground floor plan design is not the optimal in terms of the foyer so we are looking for innovative designs that will fit within the plan dimensions and our needs..
Racing drone (quadcopter) from notes to CAD and 3D model

The drone itself will consist of two pieces of moulded carbon fibre: - bottom hull - hood Key features of the drone: - two piece construction with interlocking lip - tube arms (16mm outer diameter, 12mm inner diameter) - fit 6" diameter propeller (152.4mm) - 16x19mm standard motor mounting - fit standard HS1177 camera with adjustable camera angle from 0° - 70° of tilt - fit standard flight controller circuit board (30.5mm square mounting holes on the bottom) - 4mm thick at motor mount - 3-4mm thickness of hull THE ATTACHED ZIP FILE CONTAINS SKETCHUP FILES WITH DIMENSIONAL DATA, PROTOTYPE IMAGES AND IMAGES TO USE AS A REFERENCE Deliverables: - Technical CAD model of drone components - Inverse CAD model for the moulds for both pieces - 3D renders Bonus points for: - finite element analysis to highlight structural weaknesses and suggest improvements - include motors, propeller and other electronics in the 3D renders
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.
The ROBERT project
We would like a fresh set of eyes on our device ROBERT, a rehabilitation robot that release healthcare workers of heavy and continuous lifting which can cause physical strain and pain in the back, loin, wrists and shoulders. We aim to optimise rehabilitation through more frequently and prolonged exercises which can result in fewer complications and a faster retrieval of a patient’s strength. See more at www.myrobert.com. The current look is a mixture of many components comming together which does not result in a uniform design. Further we whish to incorporate a new robot arm, made by the company KUKA, the LBR iiwa version, https://www.kuka.com/en-de/products/robot-systems/industrial-robots/lbr-iiwa. This will later come in a MEDtech version, similar in use but in white and with a small change to the interface base. CAD data of the industrial version can be used for this design, change is that wiring will come out of the bottom of the medtech version and not the sides like the industrial version, so completely round in base instead of the small square thing on the side of the industrial version (so no visible wires). The industrial version can be downloaded here: https://www.kuka.com/en-de/services/downloads. It is the "LBR iiwa 14 R820" found under division "KUKA Robotics".
