Description:
We are a company that provides innovative product solutions for the physical education and educational market. We pride ourselves in providing the most innovative, high quality product to our customer. This product would be a soft close, safety hinge used to hold the lid open on our line of ball carts. It needs to be pressure sensitive and stay open at any angle and not slam closed. It also must not have any pinch points where the fingers could get pinched. The lid would need to be pushed closed by the user. The lid itself that needs to be supported is about 25lbs., however, the hinge would need to support more in order to keep it from closing on it's own. The end user can be a student so safety is critical. There are many soft close hinges on the market, many with pneumatic functionality and gas hinges and often used on toy boxes. I have attached a photo of an existing hinge on the market just for reference. I am open to materials based on design and likely will need to be pneumatic or incorporate a gas hinge. I have included a link to our website to see the carts it would be used on. You can also see a few of the existing hinges that have been/are being used that I am looking to update with a better hinge. I am also including files to the carts themselves so you can see the product the hinge will be used on, as well as instructions that show the current hinge being used that I am looking to update. The existing hinge is not ideal as there are potential pinch points.

Wants:
Functionality of the mechanics will be the key factor in the success of the design. It needs to hold the weight of the lid at any angle and needs to be safe. The hinge must function, fit and work properly with our existing cart designs.
Don't Wants:
A design that is not going to function as intended and not able to hold the weight of the lid. In addition, I don't want a design that is too difficult or expensive to manufacture.
Software:
  1. SolidWorks
Additional Information

Open Force: 4-7lbs
-Extended Length: < 20"
-Collapsed Length: < 16"

Hi James, The weight is approx 25lbs (I mentioned this in the description) and I did add some additional specs. I apologize but I am not sure on the torque. thanks!

Do you know the weight of the top panel, or better, the torque needed to lift the lid on the current hinge pins?

Hi Zech, I would be looking for the complete assembly that would work on our carts. I just attached an image as a reference of the type of functionality I would be looking for. thanks!

Hello,

Are you looking for an entire "hinge" assembly with an integrated strut/ lift mechanism? Or simply a safety lift mechanism, for example the strut image that you attached. The strut image attached is not the actual "hinge" point.

Thanks

Zech

Hi Parvinder,
1. We use Solidworks so it either needs to be in Solidworks or something that is compatible and could be easily converted.
2. That is difficult to say without knowing the type of hinge. $5-$10 per piece
3. I am open to materials based on design but imagine it would be a combination including metal and plastic.
I also added some specifications for a a gas hinge to the project that would be helpful.

thanks!

Hello Team
Few questions I have to ask before working on it.
1. Can I use NX software to design this product.
2. What is your estimated cost of per piece during manufacturing.
3. Which material do you prefer for this product.

Thanks
Parvinder Singh

Segmented Connect-a-Hoop
We are a company that provides innovative product solutions for the physical education and educational market. We pride ourselves in providing the most innovative, high quality product to our customer. This product would be a segmented hula hoop that consists of multiple segments that connect together, allowing the user to create 3 different size hoops based on the number of segments used. This allows the user to build the hoops size they choose. The key factor in this design is to have a unique, innovative connection point that is easy to put together and take apart, holds the hoop securely together when in use and will not become weak or break when used repeatedly in an institutional setting. The connection point must be able to be taken apart and put back together an indefinite number of times without the strength being jeopardized.
do you have the right STUFF to design the COOLEST consumer electronic accessory ? radiant heat resistant material fans & radiant heat barrier aficionados .. YES, YOU DO!
I am creating a mobile phone "pouch" that has 3 functions and comes in two sizes to accommodate the most popular mobile phones on the market today: 1) protect your mobile phone from water damage. similar to waterproof phone pouches currently on the market. (picture someone laying on a pool float, listening to music on their phone) 2) reflect the heat transfer from the sun to a customers mobile phone & prevent it from overheating on hot summer days. 3) allow the customer to still access the screen of their phone with front "flap" that opens and closes easily and is on the outside of the clear, waterproof plastic pouch.

Green Key
We are looking for concept designs for our smart lock technology. There are 2 aspects to this design. We want to design the tesla of smart locks. In terms of functionality and intelligence but most of all look, feel. Something that stands out from the crowd of pretty ugly basic designs that have already made it to the direct to consumer market. Looking to innovate but also hide inside the lock somewhere for a real key that is not visible unless of emergency. 1. We are designing a reader for granting entry into a condo or apartment building, that a user will touch their phone using nfc or blu tooth. Each reader will connect directly to the cloud via iot chip inside. There will not be big cables and wiring needed in this case. 2. We are looking to design and actual door handle and smart lock for the doors of condos and apartment buildings moving deadbolt locks. These will not be individually purchased as we are a b2b business. Please evaluate the images and the companies designs i have uploaded as a base for the product line we are building. I would like similar feeling to latch, but with a little more tesla influence. That goes foe the reader of the phone and for the lock that goes on a condo or apartment. Please disregard the middle product on the screen shot for latch. We are building the first and third. Kisi as well imagine creating that reader that looks and feels so much better, something you can see in a modern building built for the internet age.
