Prototypes

1. Stretchable Sticker:

   1. 

      The product has rotational symmetry. The bag should be fairly elastic and be able to withstand hot temperatures. The outside of the bag is covered with 1/2 inch diameter rubber circles to increase friction. A metal hook is attached to an elastic band, which should be able to stretch 12 inches, to aid people in applying the product to larger items.

      

      

      The Stretchy Band has two components. The stretchy part should be made of elastic or a similar material that should be able to stretch to a diameter of 12 inches, and have a relaxed diameter of 2 inches. There is a non-slip band inside of the elastic band to stop the elastic from slipping off items. This should also be stretchy and able to withstand hot temperatures.

      
      

      

      The product can be used on a wide variety of products. The hook can be attached to the lip of an item and then the rest of the sticker can be pulled under and around the bottom.

      
      
   2. Material List:
      1. 50 Rubber Disks, 1/2 inch diameter
      2. Two Elastic Bands
      3. Metal Hook, not sharp
      4. Non-Slip Liner
      5. 1.5 square feet of Spandex

 

2. Bottle Koozie:

Material List:

1. Bottle Koozie cut to 1′ inch in height

2. 25 Nerf Bullets with suction cups endings

3. Rubber coating (Food Cover for keeping bottle still) – 1″ tall

4. Glue

5. Plastic Bearing used for “button”

6. Fusionbrands Coverblubber – reusable rubber food cover

 

3. Pulley System:

This design replaces a possible pulley system to assist with lifting heavy objects and moving them around the kitchen. This design uses a system of interlocking tracks which allow the user to move in 2D, rather than simple back and forth. On the rails sits a 4 inch by 4 inch roller which consists of 4 saucer ball bearings which allow the roller to glide with minimal effort across the tracks. A pulley hangs down in between the tracks. A rope is wrapped around the pulley and fixed on one end. The other end hangs down towards the user and when pulled, raises whatever is on the end of the rope. This end can be clipped to the pulley when at the proper height and then the user can use the same end of the rope to pull the load wherever they would like in the kitchen.

Materials:

-4 saucer ball bearings

-Popsicle sticks

-hot glue gun

-large block of Styrofoam to carve out simple track

-pipe cleaners to make hook

-simple pulley

-rope

4. Lock-and-Rock Blade

 

Materials: Cardboard, Adhesive, Pipe Cleaners, Copper Wire, String, Reinforced Plastic, Duct Tape, Glue

This is a basic overview of the lock-and-rock blade. This design is best suited for pizzas, pies, and similar circular food items that require slicing.  In theory, it would be composed largely of plastic and stainless steel, but for the purposes of this prototype, it will likely be cardboard representations of plastic and steel.  It is simple to use, with a simple pushing and pulling of the handle (labeled “rocking handle”) creating the cutting-action.  This blade can then be rotated by using the locking/unlocking mechanism located on either side (labeled “lock button”).  Additionally, there is a safety-strip incorporated which provides a way to cover the blade after use.

 

This shows the basic rocking function of the blade. There is a single lever attached to one side which is basically rocked back and forth. This is advantageous for someone with a physical disability because it provides enhanced leverage, given the semi-circle shaped blade.

 

This image depicts how the blade is rotated to cut different sections. The user first pushes both of the small buttons on either side of the blade. This will detach the blade on either side, now only being centrally attached to the very top-center of the blade apparatus. This allows the user to simply rotate the lever at the top to position for the next cut (rotating requires very little force due to being detached at either side). Then, just push both buttons again to lock into place.

 

This picture displays how the safety strip functions. After the user has completed the cutting, he/she can then pull the plastic sheath across the bottom of the blade. When not in use, the strip is pulled over-top of the apparatus. There are small attachment pieces (probably copper wire for the prototype) which allow the sheath to lock in-place over the sharp blade.

5. One Handed Meat Carver

This one handed meat carver is made of three components, the main cutting board, the two walls to hold the meat sturdy, and the knife holders to ensure that the knife cuts straight down into the meat. The first piece of the meat carver is pictured above: the cutting board. Although this cutting board might look like any other cutting board, there are two distinct differences and design concepts that make this an exclusive and the most integral part of the one handed cutting board – the center hallow lining, and the side piping. These two features are crucial to the one handed cutting board. The center hallowed out lining (the line that runs down the center of the “Top and Bottom Side of Cutting Board” picture) details the the passage way in which the walls will be able to slide in and out of the cutting board. The ends will be accompanied with pieces that will hold the walls up to ensure that they are capable of sliding within the cutting board while being able to fasten the meat within the two walls. The second hole (as detailed within the “Left and Right Side of Cutting Board”) are to hold the two knife holders in place. Although only one side is pictured, there are two big holes on each side of the cutting board that allows the two knife holders to be inserted. Along the sides of the cutting board will be a conveyer-like construction that allows the knife holders to slide along the lines of the cutting board so multiple slices of meat can be carved without the walls having to be moved.

Above, the second component of the one handed meat carver is drawn out. The walls are thick as it will help protect it from falling over while in use. It is also important to note that the bottom of the walls (as shown in the “Side View of Walls” picture) features a bottom piece that will fit the divined of the cutting board sort of like a jigsaw puzzle. These bottom piece of the walls will slide in through the ends of the cutting board, and as mentioned in the above notes, will connect to another piece of the cutting board, to provide total connectivity between the two pieces. These two walls’ main focus is to clamp the meat together and to provide a tight grasp of a piece of meat for the user to cut and slice.

The third and final component of the one handed meat carver is the knife holder. Contrary to it’s actual name, it isn’t a holder per say, but more along the lines of a guide to make sure the user is cutting their meat in a straight line and not cutting it along an angle. The knife holder is compromised of two separate pieces that connect to the cutting board through the sides of the cutting board (shown in “Left and Right Side of Cutting Board” above). In the prototype, the knife holders and the cutting board will stick together because of a piece of adhesive tape, but in a real life prototype setting, these two pieces will be connected by magnets which would allow for the two knife pieces to bend down into a flat board. Also, with the two pieces being connected by magnets, they can easily detach and be thrown into a dish washer.
