Exercise equipment design

Contest Closed
Description:
We are looking for a pretty simple piece of exercise equipment.

First, please see the attached photo. You will notice how the male is assisting the female with her sit ups by holding her feet down.

We'd like to create something that you could strap on to your shoes/ankles/heels so you wouldn't need a partner to weigh you down.

We don't want it to be too bulky of an item. Something that is light, can be easily carried, and has a good design.

#39 Adjustable Sit-up Stand by Mora Vaibhav
Its a unique height adjustable design equipped with rubber grips and foam supports which provide comfort to the trainee. If the frame is manufactured using aluminium, extreme light weight can be possible. Another advantage of this design is , there is no requirement of additional weight, but the self body weight is enough to hold the frame in stable position

#38 Adjustable Sit-up Stand by Mora Vaibhav
Its a unique portable design where we can adjust the height of the supporting frame according to the individual's body ergonomics. This design is unique because there is no need of additional weight but body weight is enough for its stability. If made with aluminium, this can be made very light weight. special grippers and foams are added so as to increase the comfort of the trainee.

#36 Romancrunch by Kalaiyarasan
Product designed with seating facility provides upward force required to grip the feet on place when person sits and crunches. In conventional product it is achieved only when holder is over weighted. Thus it is less weighted easy to carry. Design is more ergonomic.
Inspired from clubs.

#35 CRUNCHES EQUIPMENT by KP HARISANKAR
I have done simple part modeling. This is the simplest design possible. Works with the same principle of suction cup hooks. When a person gives support, he provides an average pressure of 0.05N/mm^2 to the person performing crunches. For safety purpose we can provide a pressure of 0.1N/mm^2 using this equipment by providing a vacuum area of 10000mm^2.
The red portion in the model can be rubber or cloth material thus reducing pain while performing exercise. It consists of 1 pair of stationary suction cup (black )at the 2 ends and 1 pair of movable suction cups (black with higher width) between the stationary ones. The movable suction cups can be adjusted according to the foot size of the individual so as to provide a firm grip.
The only disadvantage is that this can be used for indoor purpose only that too in smooth surfaces.

#32 Sit-up equipment by NP-Hardware
This equipment is designed to securely hold the user's feet down with a padded bar, which is pressed into position by the user's own weight.
The distance between the seat plate and the foot bar can be easily adjusted to fit the preference of the user. Adjustment is possible without the user having to change position on the equipment.
I've made the bars extend backwards slightly further than I've seen on many other designs, in order to ensure that the user's feet remain held firmly in position even when downward force at the seat plate is at its weakest (i.e., when the user has their back against the floor).
The bars and foot rest can be made from 25mm aluminium tubing, which can be given a robust powder coating in any colour you prefer. Polyurethane foam padding - standard on many pieces of gym equipment - can be applied in the places suggested on the model.
The seat plate can be made from a single piece of stamped steel. All pieces are designed to be held together, and are rendered adjustable, by a set of spring studs embedded in the bars, and a corresponding set of holes in the seat plate and foot bar.
This equipment should be light enough to be easily carried wherever needed, and in fact can easily be disassembled for easier movement if required.
Should you have any further recommendations, don't hesitate to contact me!

#31 Exercise Equipment by Artificalis
You're contradicting your own info.
You want to have a light solution what you can easely cary around, so the part where you can put something on your feet to have it as a counterweight is already gone (need to catch the momentum arround the ass). So to make it light you have to work with something you can mount to the floor and strap your feet in.
I had the ultimate solution, you can open the model and see it yourself. Its light its easy and cheap.
Let me know what you think, if you have questions, feel free to contact me

#25 Simple Situps by Nikhil Singh
Try to understand a bit complicated to explain in words.
How to use :
Sit near a wall and place it on your shoes and the straight rectangular part on the wall.Adjust the distance from wall to get a firm grip
How it works:
Shoes try to move up due to which the equipment tries to turn about the bend but because there is rough rubber at other end and it is long in length so equipment doesn't turn about the bend and thus doesn't go up. So shoes are not allowed upper movement.
Cons : Need a structure like a wall , tree or another structure for support.(but can be found easily)
Pros : Single piece!! , easy to carry , can be made foldable , simple to use like plug and play., No hassle of any strap or thinking of shoe size.
Note : I made the pics to explain the concept.The dimensions can be reduced to make it compact .Due to design the materials used need not to be too robust because legs hardly exert any upper force so light and inexpensive material can be used.
Please give your feedback asap. So I can make any changes to suit your needs better.
Thank you

More details on the options of this design. Depending on the targeted final product cost and the targeted tooling cost there are many different ways to create the center hinge. It would be best to conduct some FEA and validate the ribs with a prototype.

Use your own body weight to hold your feet down for crunches. Made of sturdy yet light ABS this design folds flat for easy transport. You unfold the product, sit down at the far end and strap your feet in. This design has room for branding and customization like a cut out for a handle. This is a concept sketch and I will build the CAD based on any questions or comments.

It would primarily be used indoors, but will be used outdoors as well.

The only function would be to hold down your feet.
Sun, 10 Jul 2016 20:12:45 +0000
Would the item need to have more function other than holding down your feet?
Sun, 10 Jul 2016 20:05:35 +0000
Is there a maximum weight? where should it be used? outdoors? indoors? both?

UAV designs
I am looking for a design on an unmanned aircraft which will have a flight time of over 1hr. It must be able to carry a weight of 7kg and a camera. I know there are loads of uav's on the market so if someone can come up with the 3D plans that then can be made to a working model. I am looking along similar lines as the scan eagle etc. The best design may possibly lead to a private agreement to design a helicopter also.
Looking for 3D Model
We're looking to hire a few talented 3D artists, who is willing to create beautiful & fast 3d models.

This relationship will be on-going and very potentially long-term. The following are the type of models we required (all of them being textured): -tech gadgets -characters -video games Before we work with you, we'd need to check out how your work looks on our site's interactive format. Create your account on our site here (http://www.sketchfab.com). Please check out one of our existing modellers for Sketchfab (https://sketchfab.com/mestaty) You can also upload existing models from your portfolio to our site, which we will check out. Thanks and looking forward to hearing from you soon
Storage Yards
I need to get a design done up for some storage yards i am creating. The area is roughly 9Ha, and the blocks would need to be 1/2-1Ha each. The area is relatively flat, however i want the design so i can work our what cut and fill needs to be done to create the areas, whilst moving the least amount of dirt. I have attached a picture of the area i am talking about, with the proposed storage yards in blue. The contour information can be supplied in a .dgn file format
Brick of Money
The goal of this project is to design a desk ornament that is a conversation piece. https://goo.gl/wc3ueb There are 3 aspects to this product: 1: The foundation: A rectangle of solid metal. Should have an expensive high end look. A bar of silver is the only thing I can think of as an example foundation. https://goo.gl/wMySnL However, I am going for more of a brushed nickel look. 2: The casing that sits on top of the medal foundation. This casing is either made of glass or plastic and will be glued to the medal foundation. 3. $500 in one dollar bills will be inside the glass casing. The attached image is not high end looking but should give you a basic idea of the kind of product we are looking to develop.
