Liquid Bandage Applicator
Problem Commercial liquid bandages do not aesthetically appeal to consumers, are messy to use and not user-friendly.
Liquid substance is unappealing, smelly and messy
Spray is imprecise, packaging unattractive
Liquid bandages sting causing users to be hesitant to use

Gentle Looking at existing products in the market I can see that they only come in brush on or spray forms. There is a gap in the market of products that are precise and gentle that my design could fill.
Liquid Material Research
Liquid bandages are essentially a self-curing adhesive which uses the same basic principles as so-called super glues. A special form of acrylate glue is mixed with chemical stabilizers/curatives to form a liquid adhesive which bonds well with human skin. As the liquid bandage dries, it forms a protective polymer shell.
Carrier H H
This is the base of the liquid bandage. It allows the bandage to dry within minutes.
This is the nontoxic â€œglueâ€? of the liquid bandage. This polymer is engineered to star t breaking down after only a few days.
tea tree oil
This is additional chemicals that are usually added to promote faster wound healing.
Ideation and Development
While exploring different forms I found that even when all of my models were hand held, the smaller it was the better it was. Also in testing the forms, users found that the ones that they could wrap their hands around felt â€œrightâ€? in their hands. I decided to go with a shape similar to that of a lotion bottle, since it was small and a form not associated with the pain of cuts or scrapes.
Injection molded Polyethylene terephthalate (PET) High density polyethylene (HDPE) has a high melting point, is chemically resistant and is non toxic. HDPE is also recyclable, resulting in less waste. It is often used in milk containers and toys so it will be safe and sanitary to use for a liquid bandage applicator.
The TSA has declared a 3.4 fluid ounce limit on liquid containers, so to make this product â€œtravel sizeâ€? that should be the limit.

Problem Cabinet space is limited and without proper utilization, clutter can accumulate. This disorganization wastes valuable space.
Difficult to reach plates at the bottom of stacks, especially from higher shelves
Clutter and disorganization wastes a lot of cabinet space
Top area of shelves go unused if dishes are not stacked on top of another
- customizable - can fit multiple dish sizes
- sturdy - simple build
- sturdy - extendible
- in expensive - can fit multiple dish sizes
- stackable - folds and stores flat
- only fits 7 dishes - assembly required - inefficient space usage
- steel scratches plates - extra set of legs makes getting to plates difficult
- heavier dishes tip it over
- complicated - expensive - very wide, does not fit in most overhead cabinets
- needs tall cabinet to stack - not sturdy

Type of Storage
One size fits â€œallâ€? Looking at the variety of existing products in the market I can see that they only are length adjustable shelves. There is a gap in the market for shelves that can be customizable while still being simple that my design could fill. There are also no height adjustable shelves on the market.
Vertical vs Horizontal Ideation
Horizontal stacking allows for a better use of space.
Horizontally stacked plates are easier to access and store.
Ver tical stacking leads to rolling and falling plates. Horizontal layout is safer.
Women homeowners who spend a lot of time in the kitchen.
Household family that often eats at home and uses dishes often.
Women who have difficulty taking out and putting away dishes.
User Interviews: “I have a hard time getting the dishes out of my cupboard. If I try to stack the same types of plates on each other, then I can’t put away the rest of my utensils, so I stack my smaller plates inside of my larger plates, but then have to move the smaller plates to get to the big plates and it’s bothersome.” “I can’t organize the inside of the kitchen cabinet well. I want a kind of organizer that I can efficiently use the space between the shelves for cooking ingredients and containers (Ziplock & lids).” “I’d like a plate shelf that you could adjust the height manually, and that won’t slide the plates along with it.”
4 - cluttered - inaccessible dishes - inefficient space usage
5 - organized - easy access - efficient use of space
Main body - Polyethylene coated steel wire. Steel wire is very durable, strong and can carry the weight of even heavy ceramic plates. The polyethylene covering protects the dishes from getting scratched by the steel wire frame.
Screw - Steel
Leg - ABS plastic which is impact resistant and tough.
Feet - Injection molded rubber feet. Rubber makes sure that the shelf doesnâ€™t slip and is slightly flexible to snap on top of another shelf.
Final Design Details The feet have cut out space that allows for them to be snapped onto another shelf. Single piece of wire that zigzags so that there are fewer sharp edges to hurt the user or scratch the plates.
The leg can easily twist upwards or downwards. Notches at intervals on the outside of the frame allow the legs to click into place at measured spots.
The rubber feet are flat at the bottom so that it does not slide or wobble.
scantunes receipt scanning music box
Problem Receipts accumulate quickly, can rapidly form clutter, are easy to lose and become a hassle to manage and organize.
Most people, especially busy moms do not have the time to manage receipts
Receipts have impor tant info that is difficult to maintain in large quantities
Receipts often end up on boxes or left in purses causing clutter
I first wanted to think about how receipts could be transformed into keepsake so that it would be less likely to lose them. Through brainstorming I found that it is the information on the receipt that is impor tant and should be kept. I wanted a way for shoppers to keep the information on the receipt but I also liked the idea of incorporating an unusual aspect to receipts like music.
Ideation and Development
A receipt scanner seemed like the best way to collect and keep the information but I felt that for every time a receipt was scanned, there should to be a reward to encourage continuing use. I reflected back to the music incorporation idea thought to combine the two ideas into a receipt scanning music box.
Market Research There are many existing products out there that help with receipt management and all of those companies prove that receipt management is a viable market. Only one company has a physical product and it is the most successful. What can my design do to be unique?
9.4 million 8 million
What if the product was for kids? There are very little educational toys that teach children financial lessons, especially to reinforce good habits.
Wooden and plastic base. Flexible touch screen to show the music and receipt information.
ABS plastic handle with rubberized finish, soft and touchable. Crank is big and playful.
Double sided scanner sized to fit all sizes of receipts
Speakers in the back.
Power button. Mini USB slot to connect to USB in a computer. This is to download the receipt information from the scanner.
Final Design Details Receipts are fed through the bottom slot, the screen will have easy simple instructions to follow. During the scan it will display the notes of the song being played.
Hand crank moves the receipt through the scanner. The movement is reminiscent of classical music boxes. The simple tune is a sort of â€˜rewardâ€™ for scanning.
It can be connected to computers via usb cable to download receipt information or to charge.
The final design is a receipt scanner that also doubles as a music box. The music is an instant reward for scanning the receipt while the scanner collects the information from the receipts for later use by adults.
Pterodactyl Pool Ride-On Concept
I believe that pool-time play is an interactive activity. It is chance for children to play in the pool with not only toys but with friends and family as well. The pool toy I have designed, therefore encourages this form of interactive play. To fos ter interplay I designed this toy to be have friendly caricature features that is easy to relate to. The design developed into a ride-on pterodactyl that has a built in squir t gun.
The squir t gun mechanism takes water from the pool sur face much like a spray bot tle. The character is silly, cute and promotes play between friends or siblings. Whether a child wants to ride a prehis toric dinosaur or jus t splash their big brother in the face with water, this is the toy for them.
