Description:
This contest is to update the current design to connect and disconnect the Donkey Calf Raise attachment to various size smith machine barbell shafts. The Donkey Calf Raise attachment is a patented apparatus that can be attached to the smith machine barbell to perform the Donkey Calf Raise exercise. The current design will attach to all smith machine barbell shafts 25mm to 35mm. However, there are currently too many components that make up the design. I need a new design that will be easier to manufacture. The new design should have a quick way to connect and disconnect the apparatus to a 25mm to 35mm diameter smith machine barbell shaft. The connecting and disconnecting method should be durable to withstand constant use. The device should be able to handle 1200 pounds. Please see the attached 3D STEP file, Inventor assembly & part files.
Attached also are images on how to perform the Donkey Calf Raise exercise.
Wants:
• A quick connect and disconnect to a smith machine barbell shaft• Commercial grade construction
• Must be very durable to withstand constant use
• Modern looking design
• It should be able to fit 25mm to 35mm diameter smith machine barbell shafts.
• Material: Aluminum
• All Designs will be 3D Solid Models
•Final submittals: 3D Step file, High res PNG and PDF.
Don't Wants:
• Do not change the overall design; just change the way it connects to the smith machine barbell• We do not want overly complex designs that are difficult to manufacture. Keep it simple
Software:
- Autodesk Inventor, Pro Engineer, SolidWorks, Solid

sir,
please make the contest blind. I'm diligently working on the concept and upload once thumbnails are blind.

Hi Achilles,
Man, I am deaapointed .Maybe you have a favorit as it look like.There is to many suggested ideas but you dont like anyone except your the idea of your favorites.Mаn, maybe you are good in fitness area but Im sure ,you dont understand nothing in engineering area.Not all is money.
All the best

@Vikram pimpale you submitted in the wrong concept...
Designers, the attachment should be able to fit 25, 26, 27, 28, 29, 30, 31, 32, 33, 34 and 35mm diameter barbells.
Do your workshop included pipe lasercuting machine?What budget for production can be convenient for your ? If it is possible please send the knowledge about .
Designers please be unique in your design. If I think you copied someone else design; I will eliminate your design.
thanks for your comment.. I'm working on it... you can send feedback through my design entry and can you please hide thumbnails ?
Very interesting project ! agree with CDDesign, could it be possible for you to hide thumbnails ?
Great contest but please hide thumbnails.
Hamed this is a good start. Lets keep the baseplate the way it is. I like that design. As for your locking devise; I like the concept. Lets make the handle have a bit more leverage and comfort when locking.
Thanks for contest.....
Hi,
Should the connection between the DCRA and the barbell shaft transfer rotational movement? Meaning if I rotate the DCRA is the barbell shaft rotating as well?

"...to fit 25mm to 30 mm..." Does this includes 26, 27, 28, 29 mm or the shafts are only 25 and 30 mm?
Interesting project,..,.........Additional prizes will attract more design entries, Thank you! (It encourages time and energy put in for the project):)
Hi,
Happy to see you again ...
I will definitely think about a new solution
Thank you .

Smart Hub Enclosure Design
We control how power flows through your home. This device, a hub device, orchestrator, controller, manager, is a small electronic appliance will sit on the table or bookcase in homes. It functions similarly to a home automation hub (e.g. Smart Things, Wink, etc.), but is smarter than a hub. It connects to smart meters, home Z-wave automation equipment, Wi-Fi networks and Ethernet. When you’re using too much power, it throttles back your home’s usage. When more power is available, it throttles usage back up.
It needs to look good, look modern, simple but elegant. We’re trying to exude confidence, control, action, durability. It needs to fit in with a modern home and look good. Attached are model files of that include the minimum features of the circuit boards and connectors. Also included are drawings of the components included on the circuit boards as well as additional pictures/descriptions of the circuit board stack. Start with the “Enclosure Presentation” file and go from there.
IMPORTANT NOTE: The bottom circuit board component/connector placement is fixed (cannot be moved/altered). The top circuit board model file currently shows 4 LEDs. These LEDs indicate system status for Wi-Fi/Ethernet Network, Smart Meter Connection, Z-Wave Device Connection and Cloud Connection. This configuration may be changed and we expect it to change, multiple colors and/or other arrangements may be used, but we must be able to at least indicate status for these 4 systems. It would be nice to indicate, in addition to blinking status for example, motion or activity in the system.
The design does NOT have to have draft built into the model for the contest, but the designer must be able to add draft (for additional fee) after the prototype has been approved. Think about how this would/could be molded when designing.
The output will be 3D Generic CAD files (i.e. step files) + Native 3D CAD.

Revolutionary Meditation Bench
A standard meditation bench made of wood gets a makeover. We are looking to create a fully-adjustable, lightweight, travel version of a wooden meditation bench for manufacture via injection molding (plastic). Here is a reference for what it usually looks like (not what we are making):
http://www.samadhicushions.com/Meditation-Bench-Seiza-Kneeling-Bench-p/C-564.htm?Click=9556
The bench consists of 2 legs, of the same size, 7.5 inches tall. Atop is a main sitting piece, which is at right angles to the legs and is 18 inches long and 7 inches deep. All parts are ½ inch thick, or thinner.
The bench needs to be able to support the weight of an adult.
The main sitting piece (piece “A” in the sketch) needs to be rotational such that it can be tilted forward in order to create an angled seating platform. This adjustment is to conform to the seating angle of the meditator to create comfortable sitting position. The piece must lock out once in place at the desired setting, in order to provide stability while sitting on it (aka it does not move).
The legs must also be retractable, such that they fold in towards the main sitting piece in some manner, in order to make the bench small and practical for travelling or storage. When folded, teethe assembly should ideally be no more than 1 inch thick.
