Problem and Justification

• Problem Statement:
• When hands-on people, such as blue collar workers, are working, they may transfer contaminants from a dirty object, the source, to another object that can’t be in contact with these contaminants, the recipient. This transfer of contaminants occurs by direct contact by the user’s hands. This causes problems with the function of the recipient and could force the recipient to be replaced. An example of a recipient is a cell phone or a shop manual. Sixty-one percent of Americans [~191,601,000 people] work in the blue collar industries (according to United States Census Bureau and kff.org), and 91% of these blue collared workers own a cell phone. This results in 174,356,910 potential customers for cell phone protection alone. These workers would want to protect their phone because, according to ubreakifix.com, iPhone or iPad’s screen cost about $120.00 to replace the screen if it becomes dirty enough to need a replacement. Additionally, these contaminants could cause potential harm to the user of the phone or other device by unintentional contact with adverse substances. Paper repair manuals, which are widely used in the maintenance industry, can be damaged to the point of unusability and need to be replaced frequently, resulting in additional costs and wasted time. Therefore, if a solution could be created that would prevent the damaging of the recipient lots of money and time could be saved.

Top 4 Solutions

1. Crow’s Foot
2. Roll On
3. Top Removed
4. Finger Tip Covers

1st Solution Prototype Aspects

• Crow’s Foot
• Ease of use
• Is only one hand needed?
• Can it be put on easily?
• Does it stay on?
• Does covering three fingers provide enough protection and grip?

2nd Solution Prototype Aspects

• Roll On
• Does it return back to its normal state when taken off?
• Is it easy to put on and off?

​

3rd Solution Prototype Aspects

• Top Removed
• Does it come on and off easily?
• Does it stay on?

4th Solution Prototype Aspects

• Finger Tip Covers
• Can it be put on and off easily?
• Does it stay on?
• Does it provide protection when worn?

1st Solution Prototype Results

• Crows foot
• Ease of use
• Gloves can be put on with one hand (second hand needed to keep glove from sliding, but can be solved with a high-friction surface like velcro)
• Does it stay on?
• The more fingers the glove has, the better it stays on, but none of the prototypes had problems staying on
• Provide protection and grip
• The less fingers the prototype had, the less grip (the glove would slide around on your hand) and the less protection the glove would provide

​

2nd Solution Prototype Results

• Does it return to its normal state after being taken off?
• When taken off, the glove returns to its original state most of the time, however occasionally, one of the hooks will not catch and it will not roll up
• Is it easy to take on and off?
• The glove is fairly easy to take off, but it requires a bit of practice it get the hang of it initially. It is fairly difficult to put on, as fingers must be aligned exactly, which takes time and 2 hands.

3rd Solution Prototype Results

• Stay on?
• It stays on very well because of the long finger slots

providing stability

• Easy to apply and remove?
• Would also require the use of a high-friction surface

like velcro to hold it down so that it could be applied

with one hand. And because of the long finger slots,

more precision is needed to take it on and off.

4th Solution Prototype Results

• Can it be put on and off easily?
• It can be removed easily but requires a little bit more time

to put on

• Does it stay on?
• It stays on very well since the fingertip covers are a little

closer than finger length so an outstretched hand will

not allow it to come off

• Does it provide protection?
• The product provides semi-protection since it covers a large area of the hand when worn, making a barrier

Project Construction

• Glove
• First version- Modified canvas work glove. Top cut off, and wire inserts added to openings to fingers to make it easier to insert your fingers. The thumb was in a awkward place, and the glove was not stiff enough
• Second Version- Began sewing our own gloves out of vinyl, did not work very well. fingers were too tight, thumb was off.

Project Construction

• Glove cont
• Third version- Outside help was brought into sew the glove. Fingers were big enough and thumb fit. This is the version that is used in our current prototype

Prototype Construction

• Cuff
• First version- 3D printed, but was found to not fit the user’s wrist as well as hoped, and thinner than desired
• Second version- Still did not fit the user’s wrist , and was still too thin
• Third version- Fit the user’s wrist as well as expected, and was thick enough

Prototype Construction

• Cuff, cont
• Fourth Version- Completely revamped design. The old design was not performing up to specifications, so we needed a new design. The new concept involves sliding the cuff over the bolts instead of placing it on top of bolts. This is version is on our current prototype

Project Construction

• Bolts
• First version- Lathed ¼-20 carriage bolt. Head was not large enough to keep cuff on base, and lack of slope on underside did not allow cuff to be taken off of base easily
• Second version- We welded around the head before lathing, which allowed for bigger head and sloped underside

Project Construction

• Bolts, cont.
• Third Version - Unmodified 6-32 x 3/4 bolt to work with new, revamped cuff design. This is the design used in the current prototype

Project Construction

• Base
• First version- 3D printed in two parts, and then epoxied together. Rubber grips were epoxied to the back to keep the base from sliding. Did not fit the user’s hand perfectly, and was very thick to store the cuff.

Project Construction

• Base, cont.
• Second version- Slightly modified hand design, slot to store cuff was removed in order to accommodate new cuff design and significantly cut down on amount of plastic use. Non-slip mat was added to the bottom to prevent the base from moving. This version is used on our current prototype.

Final Prototype

• Our final prototype incorporates the most recent versions of each part, and involve the user putting their palm on the palm of the glove and sliding their fingers into the fingers of the glove, then pulling back to release the glove from the base. The user then returns the glove by placing the glove slightly behind the base, sliding forward, and then curling the fingers and the lifting the palm of their hand up and out of the glove

Testing Reflection

Testing Reflection

Since all of the tests were relatively simple, they were able to focus on specific aspects of the product and give us reliable data back in return. And because these tests are simple, they can be repeated easily and even executed by other people. So with the tests being specific to every aspect of our product, there is very little limitation when running these tests, so these tests are very credible. Lastly, our product was able to complete every test and succeed, so we consider our product to be effective at completing our goals.

Project Recommendations

• Prevent glove flapping around when glove is held parallel to the ground
• Even quicker to use the glove, specifically taking the glove off
• Stretchy fingertip covers for bigger hands

Project Recommendations, cont

In order to bring the product to the market, ergonomic optimizations will have to made to the glove. These deal specifically with taking off the glove, the shape of the handprint in the base, and the size of the glove.

Designer Process Reflection- Aaron

If I were to do the whole project over again, there are several things I would do better, however as a whole I believe that the project was a success. The first thing I notice is that our most current prototype is not the solution that I would go to the market with, there are still small optimizations that need to be done. These optimizations do not require any special materials or expertise that was not available in class, rather it only required more time. Therefore, a better management of time could of helped bring our project close to a market ready solution. However, I feel that our time management was optimal during class, so that leads me to think that working outside of class could of added more time for us to work with. However, with extracurricular activities such as track and a fairly heavy class load, I am unsure how feasible this is. The other thing I would do better would be to be more open to new ideas that were not brainstormed while prototyping our project. We spent too much time working of the cuff perfecting the cuff on our glove, and did not change it until the last minute when we finally realized that it would not work. The extra time spent prototyping could've been spent on finalizing and optimizing our product to make it more market ready. The two things that we could of been better both deal with time management, and I believe that that fact represents how our project went as a whole. A great idea with good execution, but just a little more time (maybe a week), and we could of taken it to that next level.

​

Designer Process Reflection- Lukas

If I were to do this project all over again there would be a few things that I would change, but overall this project turned out very well. That being said something that I would change is I would dedicate some time at the beginning of each week to sit down with my partner and talk so that we both are on the same page on where our project is, and so that we could figure out what still needs to be done and when it will be done later that week. But as far as the design of the product goes, I feel like we could have spent more time on how we would design the final version of the cuff for the product. Now we did decide to revamp the design late in the prototyping process, but this new design didn't receive the same scrutiny that our main solution brainstorming received. And I feel like we could have come up with a better design, but as I said earlier, this was late in the prototyping process and we were running out of time. So even though we were efficient with managing our time, I feel like we could have been better at realizing when we needed to revamp our design so that the new design would meet all of criteria and feel natural in use. Something else that I would have done differently would be spend more time on making sure that the applying and removing of the glove felt very natural since the main type of comments that we received from our presentation were people commenting on other ways that we could make the transition of glove to no-glove easier. So if this project were to be redone I would constantly remind myself about how important that aspect is so it would always be considered in every decision that we made.

Designer Process Reflection- Lukas

Overall, I would make sure that we didn't commit the deadly sin of sticking with an idea that almost works way longer than we should and I would make sure to remember that the most important part of this product is how people use it and to really focus on the idea of user ergonomics since that was the biggest piece of feedback that we received.

Project Process Documentation- Aaron

I believe that with a combination of the Google Slides file and our engineer’s notebooks, anyone interested on our problem could pick up our work and replicate it. However, the Slides file alone (which is what I believe is implied by “portfolio”) is missing several things that, while they would not keep anyone from picking up where we left off, they would be confused on several minor things. The first thing that they would be confused about would be that would be the “why” in many of our decisions. While our decision matrices and justifications do help, they did not take part in our discussions, or read our notebooks, which contain information dealing with discussions. This would not inhibit someone from picking up where we left off, but it could leave them with some unanswered questions about why we made the decisions we did. Besides adding this to our portfolio, we could of also added some things that were in our portfolio to our notebooks. For several of the early assignments, specifically those that used Microsoft Word/Google Docs were not included in our notebooks, just mentioned in our reflections. Simply doing these two items could easily help keep anyone else who would be looking to pick up our project at a later date to proceed without further questions. Additionally, like always, neater handwriting will help those without this gift to understand what I am trying to communicate. As a whole, our documentation is complete, however the Google Slides file itself could contain some holes that would lead to questions, but inhibit an understanding of the project as a whole and someone could pick up where we left off.

Project Process Documentation- Lukas

I believe that throughout our project we did a good job at documenting our ideas and that if anyone wanted to continue from where we left off they could. Our main source of documentation was our powerpoint, and this had a good mixture of technical and non-technical so that almost anyone can look through it and get an idea of what we did. We also had a lot more technical information stored in our google drive folders so that once a person flipped through our powerpoint, and became familiar with our project, they could start looking through those files that contained more of our thought process when we were doing our project and get a better understanding of our project. One example of this is our decision matrices that we used to help us decide on our final product. When we created them we made a list of criteria to grade our ideas on, and then we made a document that explained not only why we decided to grade the ideas on these criteria, but what would need to happen in order for an idea to score high in each aspect. So I feel like if someone wanted to learn about our project, they would be able to but they would need to have a little bit of patience while they were searching through our notes because even though it is all there, it is a bit disorganized. Another way that somebody would be able to learn about our project would be to look through both of our engineering notebooks that we used to keep daily notes and explain what we did every day.

Project Process Documentation- Lukas

So I feel like if someone wanted to learn about our project and the reasons for why we did things, I feel like they would be able to, but to make this process even easier I feel like we could have been a bit more organized in our documentation, whether it is through documents and spreadsheets, or our engineer’s notebooks.
