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.

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?
Hi....Fabrizio
According to your considerations
The main frame material you want to use is more square or tube in shape

Mr. Cad Designs, that is correct. The user will have the chest rest to lie his chest on that platform. The user will not lean on the rear platform because he will be standing up pretty straight to use the machine. I do want to note that this machine needs to include 30 degree tilting options for position variation. The top front platform should be able to tilt upward and downward 30 degrees as well as the other supports that I showed in the initial drawing. I will upload one more rough drawing to help clarify. Please let me know if there are additional questions.
Hi Kieron, I do not want a standing leg curl machine. I referenced that machine to give you designers an idea of what these types of machines look like. This design is for standing leg extensions.
Creative Paul, the thing on the right is the housing for the leg lever mechanism. There won’t be a dedicated seat for this design since it is a standing use machine. Imagine standing up, leaning you chest on a table with peg handles to grab onto, while taking one leg and bending it upward to lock into the shin pad support beam/foot roller to then perform a leg extension. The peak of the exercise would result in the keg being fully extended as though you were standing normally, except one leg will have a load from the weight and the other leg would be resting for support.

Large 3D bookshelf backstop
Inspired by the historical visual progression of mainboards, we are looking for an innovative design to use as the back of a large shelving unit.
We are looking for a design to go in a display case. The display case will then be used as a holder for glass shelves.
Think of it almost like a glass bookshelf. Except, instead of the back being a cheap piece of board held on with tack nails like a shelf from IKEA, the back will be the design you come up with.
Dimensions:
8ft wide
3ft high
1-3in deep
The case is being used to display tech items. So we would like the design to reflect technology. Think mother board but on our scale.
The original thought was to collect old motherboards, including ram and cpus. We were then going to lay them out on a 8x3 piece of plywood and glue them.
Instead of this, we now want to get a design that a CNC machine can make.
Material used:
Wood and old metal.
The design should induce a feeling of technological progression. So from left to right the design should transition from old circuit board tech, to current tech, to possible future tech (this part is open for interpretation)
As an example, in the attached picture, the green part is what we want to replace with our 3D circuit board idea. Please note that the picture is just one from google and does not represent the actual shelf we are building The entire shelf will sit on top of a table, meaning that it will be at eye level for the average person.
Power SPDT Relay implemented with MOSFETS
I am currently using the following relay in a product:
http://www.digikey.com/product-detail/en/te-connectivity-potter-brumfield-relays/RT424024/PB969-ND/1095293
It is a DPDT, non-latching relay rated for 8A switching, and a 24Vdc coil voltage.
The problem: The "clicking sound." This is for a home audio application, so we need it to be silent.
I am looking for a silent version, using MOSFETS for example, built onto a daughter board (PCB) with the same footprint and pin-out as the relay.
Note - I only need SPDT capability (I tie the two poles of the DPDT relay via on the board that the relay is installed onto).
One side of the relay coil (pin 1) is always tied to 24V. And the other side is either set to 24V or GND via this chip:
http://www.digikey.com/product-search/en?keywords=296-19046-5-ND
(which is controlled by a PIC micro)
Requirements:
- An electrical schematic of the new design
- A BOM of all the parts required
- Gerbers for the PCB daughter board
- Same footprint and pin-out as the RT424024 relay.
Note, for this SPDT version, the following pins will be tied together (12 & 22, 11 & 21, 14 & 24). They are already tied
together on the PCB that the relay currently is soldered to.
- Same 24Vdc "coil voltage" (pin 1 always tied to 24Vdc, and
pin 2 is controlled externally to be 24Vdc or GND via the
external chip mentioned above).
- When the relay is not activated, pins 12 & 22 are connected to pins 11 & 21). When the relay is activated, pins 11 & 21 are connected to pins 14 & 24.
- Use high current MOSFETs (the lower the turn on resistance, the better! Should be able to handle > 25 Amps continuously (ideally > 50 Amps continuously).
- Must have full protection from ESD / over-voltage on every pin.
- There must NOT be 'cross-conduction' of the pins.
- Must be very reliable
- Must be silent switching
- Must be the same footprint and pinout as the relay that it is replacing (Mentioned above). Max. height is > 1 inch (we are only limited by the footprint, not the height).
- Layout software can be whatever you want as long as I can get the PCB gerbers to send to my PCB house.
- BOM should be in a spreadsheet (excel)
- Electrical schematic can be in PDF
