Introduction:

The Pristine Pedal™  is brought to you by PristineⓇ, this product takes the old design of hand sanitizer/soap dispenser and revolutionizes it by introducing a foot pedal that allows for the user to use a soap dispenser without risking their hands being contaminated. The Pristine Pedal™ is especially useful in places without electricity and during crises, like the Covid-19 pandemic. A crisis in which hand contact with unsanitized objects can lead to undesired consequences. This innovation doesn’t require the use of electricity, in this statement, this will allow it to be used in a variety of areas, including areas that are technologically restricted, it may be placed in areas such as public parks, sidewalks, and trains, buses, and subway stations where normal outlets for technologies are non-existent to current times. There are two versions to the Pristine Pedal™, the Indoor version and the Outdoor. The Indoor version can be easily mounted on a normal wall and the Outdoor is recommended for outside use, this version comes with a built-in stand.

Pristine Pedal™:

The Pristine Pedal™ can be divided into two major parts: the dispenser and the foot pedal. The dispenser is where soap or hand sanitizer is held in and released from. The dispenser is made of primarily plastic while the foot pedal consists of parts made of metal, plastic, and synthetic fiber. The foot pedal’s purpose is to be able to step on it and its connection to the dispenser will cause the dispenser to release soap or hand sanitizer ideally onto an individual hand(s). The foot pedal is made of a variety of components. The rope is present in all parts of this device, as it connects from the dispenser to the foot pedal, and depending on the version, the user is using it can include a stand-in in which the rope is inside the stand. The major difference in our product to this is that there is no need for any hand contact to object contact or use of electricity in order to use the Pristine Pedal™.

The Foot Pedal:

The foot pedal is primarily built of 7 components. These components are the top and bottom of the pedal frame, a (1.5 meter) rope, a roller (4 inches), a hook, and a rubber band. The rubber band is placed around the hook, which is connected to the roller, and twisted for tension so that the rope is constantly being pulled into the pedal.  The spring resets the pedal back into place. The bottom frame is the most important as it holds all of these components together, the top pedal connects to the bottom pedal in a hinge-like fashion.

On the top pedal, there is a downward angled semi-circle, the rope goes through a hole. This is innovative because, as the user applies the pressure and brings the pedal down, the angle of this circle will become even tighter for the passage of the rope, thus creating a tighter hold for the rope. The downward motion of the pedal will then put even more tension on the rope that goes through the shaft and into the Inside of the dispenser, which then pulls mechanisms in the Soap dispenser box, which then pushes the soap out.

The Outside of the Dispenser:

The outside of the dispenser is primarily built of 3 components. These components are outer Frame, nozzle, and Company Logo. The outer frame connects to the circular Nozzle that extends outward 3 inches. The Nozzles hole is about a 2mm radius. The company logo is (5 by 6 inches) and states “Pristine Pedal™”.

The Inside of the Dispenser:

The inside of the dispenser is primarily built of 5 components. These components are the soap bag with a nozzle connector (one inch from the bottom of the bag, 2 inches from the front right), an extended Straight Bevel gear, a clamp bolt, an extended C-Clamp, and a rope. When the Soap bag with a nozzle connector is fully filled the dimensions are 10 inches in height by 6 inches in width and a depth of 5 inches. The Clamp Bolt is a long-threaded bolt designed at (7 inches) to tighten down  from rotation of the Bevel gear from the rope. This moves the Extended C-Clamp, forcing the Paddle to apply pressure on the soap bag, thus pushing the soap out, dispensing it through the nozzle, and exiting the dispenser, ideally into the hands of an individual. To further explain this innovation, the Extended C-Clamp is 5 inches in height and a plank that reaches to the other end of the soap dispenser box is attached to the top of it, thus modifying and extending the traditional C-Clamp. Also, the nozzle connector on the plastic bag connects to the nozzle of the dispenser frame like a household hose would.

The Stand:

The stand allows the soap dispenser to be placed anywhere and everywhere.

The stand consists of a hollow frame with a flat screw knob and rope.The frame is adjustable as it can span from 3 to 5 feet, with the adjustment being held together by a planted screw knob. The rope runs through the Hallow frame connecting the pedal to the Soap Dispenser Box. The stand is included in the outside version of the Pristine Pedal™. 

Building the Pristine Pedal™:

This is quite a simple process as everything will be three-dimensional printing, all of our frames will be 3D printed with hard plastic materials. The only metal components will be the spring. The rope will be made out of the synthetic fiber. Pristine expects that the manufacturing process will take 2 hours for completion, but there is an opportunity to have non-stop mass production using assembly lines. Pristine will then be able to make 30 pieces an hour. Pristine expects to have very cheap raw materials imported from local facilities and other U.S. facilities. Pristine expects to spend $5.00 on each Pristine Pedal™ printing material. These numbers are based on “ABS and PLA starts at roughly $25 per kilogram. With one spool you should be able to print about 500 chess pieces” (How Much Does a 3D Printer Cost?). In terms of the metal springs and synthetic fiber, they will be made in America, the springs will cost $0.40 each (Springs Fast). The rope will be a 6mm Synthetic Uhmwpe Braided Winch Rope/ mooring rope, this will be costing us $1.20 per unit (Alibaba), as each dispenser will have 1.50 meters of rope. 

So this will cost us totally about $6.80 in materials and when production is at 30 pieces an hour Pristine can spend $.50 a piece on labor. With the base pay of $15.00 an hour. So our total cost is about $7.30 a Dispenser. Maximizing profit for about $12.70 for the indoor version and about $22.70 for the Outdoor version.

Refillability:

Not only is the Pristine Pedal™ affordable, easily movable, and can be accommodated in almost any area but it can be easily refilled at any time. All that is needed is a new Pristine Soap or  Pristine Hand Sanitizer bag, the bags will both cost $12.00 and will have the capacity of 2 liters. To change the soap bag within the Pristine Pedal™, start by opening up the dispenser by easily rotating the seal present on the back of the Pristine Pedal™. Then pull out the back cover. Pull down the old soap bag and twist the nozzle until it unties, then removes and places the newly filled bag. From there just place the Pristine Soap or Pristine Hand Sanitizer into the Pristine Pedal™ and twist to tighten the nozzle shaft, just like a normal household hose, tighten it firmly and close the dispenser box and you are ready to go. 

Nothing Compares to the Pristine Pedal™:

The original design of the soap dispenser was a good starting point but due to the Pristine Peak has caused it to seem outdated and a relic because even though the original soap dispenser is compact, it does not require electricity, and can be used anywhere. Its biggest hindrance is the fact that it requires physical contact with the soap dispenser because ultimately the user is undoing the work they put into getting their hands clean by coming into contact with the soap dispenser.

Electric soap dispensers take the idea of being hands-free and introduce a more expensive and a very limited machine in terms of placement. The only way an electric soap dispenser can work is if it is connected to a power outlet where it eliminates any chance of being used outdoors due to damages being caused by coming into contact with water and other liquids can.

Another key difference between the original design of the soap dispenser and electric soap dispenser to the Pristine Pedal™ is the price. The highest-rated regular soap dispensers on Amazon cost $18 dollars (Soap Dispenser). Electric soap dispenser cost fluctuates vastly with some being 35 dollars to others rising to the cost of over $100, all the while not including the amount of electricity it takes up and will cost the user in total (Electric Soap Dispenser). Pristine Pedal™ is head and shoulders over the original soap dispensers and electric soap dispensers because the Pristin Pedal™ maintains the affordable price of the original soap dispensers while also having the hands free feature of the electric soap dispenser.  

Conclusion:

The Pristine Pedal™ takes an old fashioned idea and revolutionizes it and introduces a much safer and cleaner way of cleaning an individual hand while also being a cheaper alternative to the electric soap dispensers, while also providing a clear alternative to the original design of the soap dispenser. Not only is the Pristine Pedal™ a cleaner and cheaper alternative to other soap dispensers but it is also refillable and can be placed anywhere the user intends to put it.

SELF-REFLECTION

 

KENNAN TERZIC

In collaboration with my group, I had a great experience. I state this because my group was always ready to work, they were highly cooperative, open to new ideas and open in communicating their rich ideas. I am very happy with how hard working my group was. I am proud of everything our group did. I am proud of Hussam and Bryan. I am proud of our creative ideas.

In my group I have taken the role of managing and organizing, in my organization, I have set the times in which my group will meet, I have created and organized a document that we have used. I have organized our ideas, narrowing down the product in which our group will pursue. In the process I and the group have all worked hard in planning and in the making of the video. I have worked extensively on the diagrams for our product.

 I now have a better feel for creating videos. I believe this was a great project in showing us how to cooperate with one another, by putting our group skill to the test. As it took our group, 4 (8 hour) days to finish the entire project. This project has really tested our organization and our communication skills. In which we had successfully overcome. This project has tested me in the technical description. As when creating a new product it is hard to name a part that you have invented for a device, such as the “extended C-Clamp.

Some things that I would like to improve on in the future are the technical description, I believe my own personal ability can be improved upon. Also I am really happy with the result with the circumstances that we had upon ourselves, from communication to our working setting.

In final thoughts I enjoyed this group project and have made new friends along the way. I enjoy our creativity. I am glad for this opportunity.
