Defining and Justifying Problems

Problem Statement

Relatively speaking, when walking around your house you are safe, but for around 50% of people, there is a good chance you will stub your toe at least once a week. For the people who do stub their toe, when you feel your foot jams into a wall or furniture it is always a very painful experience, and it can lead to other problems such as broken nails, infections, spraining, and in the worst cases, fractures.

What do potential customers say?

We sent a survey to our entire school with questions pertaining to our project, with questions like, “How often do you stub your toe?” and “when was the last time you stubbed your toe?” Our aim was to find justification for our problem. Here are the results.

This pie chart shows that about 36% percent of responses said that they stub their toes weekly or daily. This means that many people frequently stub their toes, giving us a large target group.

What do potential customers say?

30.9% of potential customers say that they would be willing to purchase a product that could stop them from stubbing their toe. An additional 39.5% of customers might buy a product depending on how it worked.

Justifying the Problem

Wearing shoes around the house is a great way stop yourself from stubbing your toe, however based on our survey with 256 responses, only 5.1% of people like wearing shoes around the house, and of those 5.1% of people over 80 percent of them also like to wear either socks or bare feet around the house, so while wearing shoes is an almost foolproof solution, it's not the solution most people want. We need to generate a solution that keeps all of these ideas in mind and uses the opinions people have given us.

Design Specifications

Design Criteria

Form

The size and shape of the product will be formed dependent on the foot size.
The standards of the product would be within 2” by 5” by 1 ½”.

Material

If we could find a soft silk material with metallic supports, it could strengthen the lifespan of the product.
In search we would like a smooth textured material that is durable to prevent tension with the toe and surfaces interacted with it.

Aesthetic

We would love if we had the ability to have variation colors to our product.

Ergonomics

Must attach to a person’s foot comfortably without being too big, must work with any shoe size and while wearing socks.

Safety & Legal Issues

If the product does not perform as well as we say it will we could be sued for lying about our products abilities, and then be forced to pay for medical damage it has caused any person we sold it to

Cost

We intent to create a product costing within the range of 5 to 15 dollars at the most.

Constraints

Resources (people, equipment, etc.)

We have 4 Engineers with the ability to use a 3D printer, CNC mill, access to the internet, phones and ability to go shopping.

Budget

We have a maximum limited of $50, covering the prototype, designing & testing, and the creation of a manufacturing process for the product.

Time

The project has been researched & will continuously be researched as well as plan, designed and prototyped in the end bing finished by 5/30/2020.

Energy

Able to use automation without human error or hault.

Materials

Malleable , lightweight, comfortable, not sticky, smoothly surfaced.

Manufacturing Process

Automatable and manufacturable without human faults.

Parameters

Testing

Must last 3-7 days on the foot and still work.
Withstand 10 hits into the wall, and then an additional 10 hits into the corner of a bed frame
After step one and two, it must survive one wash in a washing machine.

What constitutes a success

No damage to the foot using the product.
No significant damage to any part of the product.
The product survives the washing machine and comes clean.
If the product still work after one week.

What constitutes a fail

IF you feel pain in your toe it did not work.
If the product breaks or bends while stubbing your toe.
If it does not survive the washing machine or does not come clean after using.

Analyzing Prior Solutions

13 of 15

Existing Solutions

Gel toe caps

Gel Toe Caps prevent blisters, rubbing, irritation, and possible toenail loss, absorbing pressure, providing a small space between your toe and shoe.
Medical-grade silicone gel, designed to stretch and stay in place, treating sore nails, protect toenail injuries, and relieve pain in toes.

Bed frame 3D print covers

This only works for beds not everywhere else

Mesh Shoes

Very flimsy and does not prevent stubbing your toe.

Rubber Socks

Flimsy and have no real protection for the toes.

Steel Toe Shoes

Anti-smashing : Widening the European standard steel head 2MM, not only can withstand 200 J impact, but also allows you to work easily, without the toe injury caused by too tight steel toe cap.

Compression Socks

Does not prevent stubbing your toe, but does put pressure on foot.

House Slippers

Have a flimsy toe front and are only meant to keep your feet warm & not slip.

Metal Toe Guard

Uncomfortable and heavy and would put a hole in the wall.
