Description:
I would like a professional design for a workout machine prototype. I plan to push it into production soon. I attached two very basic drawings to give a super high level overview of what the machine *can* look like. Please review because there are important features in the mock ups that should be included, which is different from many other machines on the market. I’m open to different designs but it must function proficiently as a standing leg extension with the necessary features that are mentioned below. Here are details about the project:- This is a standing leg extension machine.
- The material should be sturdy metal. A strong durable type of steel, something that’s commonly used with well made machinery is fine. It will need to be heavy so that it won’t move under load. The vertical steel supports should have holes on each square side so pegs can be installed if users want to incorporate resistance bands.
- Dimensions are as follows:
- 4 feet tall | 4 feet wide | 6 feet long. Top chest rest: 2 feet long. Bars with handles should be another foot in length, with ability to extend and retract. Small vertical bars should be 2 feet tall with extension and retraction functionality.
- The front of the machine should be longer to compensate for the weight in the rear.
- The steel should be adjustable meaning there should be an inner sleeve for each vertical bar to raise or lower the height. Also include this in the chest rest parallel bars.
- I also want a bi-way tilting option for the parallel chest rest so the individual can bend downward toward the ground or upward for exercise variance.
- There should be another bi-way tilting option at the bottom for the 4 foot vertical bar.
- There should be a supportive pad on the tall 4 foot bar to comfort the belly/ chest area during exercise.
- There will be two foot extensions, each with their own foot roller and supportive pads (two pads per extension). The extension mechanism should be welded into the steel so it’s strong and supported. It will also need to extend and retract to support users with short and long legs. I want it to be connected to the smaller parallel bar with an L shape toward the inner “swing area” of the machine. The end of the L will have a foot roller and right above the foot roller should be two 8” shin pads (one for the left side and another for the right side of the shin). This will support the leg more so, in order to keep the individual from relying on the foot roller alone to perform the extension.
- This will be a cable pulley machine (flat plates included) with a round plate loaded option as well. A peg on each side will be needed to accommodate the round plates.
Wants:
Since I desire to move this machine into production, the design will be key. I need this to compete with the looks and functionality of Life Fitness and Rogue Fitness products - please educate yourself with latest machine build designs and functionality. Must be familiar with equipment aesthetics and machinery, rotary pulls, hinges, bracketing, bearings, caps, support placement, and general machine build mechanics. Color of machine will be in the RGB color model #e59b9c. Thank you for submissions! This really means a lot and looking forward to working with you.
Don't Wants:
Overly simple design. This can look cheap and commonplace. Machine should be sleek and robust. This should look and perform like a strong competitor in the strength training industry. Quick, average designs will not be enough. I desire to work with someone who has existing knowledge with machinery/engineering design to create a high performing product that is worth the financial investment. Designer thoughtfulness is required.

can we have a link, picture or any video towards an aproximative model?
hi everyone, i am new here, i haves some questions about the loads which will be applied on the legs, do we have to provide place for discs ,mass or something else?
Dear client. One question: are we allowed to add 2 another metal elements, 2 feet each? In that way, my design will functional
Hey, Fabrizio. Does the 6 ft length a fixed dimension, or is it a maximum?
Sorry for the late discussion, I just found out about this contest.
Hey, so basically the mechanism for the machine is the reverse of the leg curl mechanism (legs swing from back to front, while leg curl is from front to back?)
Hey are you familiar with Consumer Product Safety Commission safety standards for fitness equipment? If you are selling this product in the US it may be important to know before making a decision.
It's not clear what you want your design to do. It is preferable if you tell us your wishlist of leg exercises you want to do with this machine and which muscles you want to develop with this machine. Then we, designers, will create one for you. You review each of our designs and provide feedback. A random Designer will eventually create a functional exercise machine that meet you expectations. You can then follow up with that designer, informing him or her of any upgrades or modifications you would like to make to his or her design.
Hi,
It would help a lot if you attached some inspiration images and video links with people performing the proposed exercise.
It is a project that requires a good analysis and will take a long time to execute, and we would like to be sure that we are starting with a project that is on the right track.

I HAVE THOUGHT OF A DESIGN WHICH IS SHOWN IN THESE DRAWING. IN WHICH I MENTIONED ABOUT THE LEG PART ON WHICHI WILL DESIGN. IF YOU AGREE ABOUT THIS PART, IWOLD DO BETTER TODESIGN MY NEXT ONE.
Hi Marka1, this will be a standing leg extension machine. The user will be mostly vertical on the machine with one leg bent at the knee, with his foot above a lever so that he can extend the lever on a downward rotational axis to work the quadricep muscle.
Hello, I will be drafting a design.
Based on the side view sketch, isn't this more of a standing leg curl machine than a standing leg extension machine?
I look forward to submitting a concept.

Looking forward to it GalaxyRobotics. Please let me know if you have any questions.
Hello, I will be drafting a design. I am excited to work with you!
Hi Michael, you are correct with all your analyses, except for the machine resembling a cross country skiing motion. The motion is this. Standing leg extension of the quad. It will be accomplished by bending one leg, while standing up. That leg will have a foot roller in on the toe of the shoe and two shin pads sandwiching the shin. At this point, the individual will extend/ push the lever forward do that the leg is in a fully straight position at the climax of the movement. Think of the leg swinging from a bent position to a straight position.

Chaniago, yes that is correct. Square not circular.
chaniago, yes that is correct. Square not circular. 
Let me see if I understand what you are asking for; a standing exercise machine that is primarily designed for working the extensor muscle groups of the leg while supporting the upper body in a semi upright position. Is this correct? If so you describing something similar to a device that would mimic cross country skiing motion? Am I on the right track for what you are looking for?

Angled Keyboard Slide
The design requires a clean simple method with minimized parts and manufacturing costs. Product is low volume, 250 to 500 pieces per year. We are interested in minimizing capital tooling costs. Design challenge is to design a keyboard slide platform that sits at a 32.5 degree angle (see attached documents). Keyboard slide needs to easily lock in upward position when not in use, and needs to easily be released and slide downward when in use. The keyboard slide is on a cart platform, so when the cart is being moved around, if it gets bumped, we do not want the keyboard slide to dislodge and slip into the down position.
Engineering design: extending foundation pile support
3 different components need to join together to form 1 piece.
The combined assembly is a clamp on system, that clamps onto 36" diameter pipe, then when hydraulic pistons are activated the arms extend and lock out to approximately 45deg.
I have attached schematics showing in 2d what I am after. Potential for significant future work for winning designer.
