# P1. Prototype!
:::info
The goal of this phase is to define & materialize 3 relevant product proposals according to the subject given.
:::
:::danger
Your prototype must be a physical object : diagrams, images, drawings and 3D files etc. will not be considered as prototypes.
:::
## Define & prototype 3 proposals
### Proposal n°1 : Bag Handle
##### Actors
:::warning
- BY WHO? We are students and we want to help homeless people
- FOR WHOM? homeless people and elder people
- WITH WHOM? Shelter communities & supermarkets.
:::
##### Context
:::warning
- WHY? Because homeless people always have to carry their life with them, which can be heavy and damaging to their hands.
- WHEN? When they move their bags around.
- WHERE? In the streets moving going to the shelters
:::
##### Features
:::warning
- WHAT? These are bag handles that homeless people can put into their hands when carrying their heavy bags.
- HOW? The homeless person puts the handle into their hand, which protects it from friction when carrying the bags. The handles are small and can be kept easily in pockets etc.
:::
##### Usage scenario
Describe use cases
How will users access your service?
Describe scenario of utilisation, and add a drawing for each steps :
:::warning
**Initial context:**
The homeless person has all of his things in bags that he has to carry around when he has to move. Homeless people will usually move around, even for short distances - whether it is because they are forced to or to find a more confortable location.
:::
:::warning
**Action 1:**
The homeless person puts all of his stuff in bags that he carries around.
:::
:::warning
**Action 2:**
The homesless person carries these bags around, they are heavy.
:::
:::warning
**Action 3:**
!
The homeless person's hands become damaged from holding the heavy bags.
:::
:::warning
**Resolving situation:**
The homeless person is able to put the bag handle into his hand, and then hold the bags with it - his hands are protected from damaging friction.
:::
##### Benchmark
List concurrents and relative projects and describe how they relate or differentiate to your project
:::warning
* In China - Food Carrying Handle (https://www.alibaba.com/product-detail/Bag-Accessories-16cm-Plastic-Luggage-Handle_60715350248.html?spm=a2700.galleryofferlist.0.0.316e4e5cmZFwS1&s=p)
* Grey Dog Imports - Grocery Bag holder (http://www.greydogimports.ca/12-pack-silicone-grocery-bag-holder-handles-magnoloran-multifunctional-candy-color-handle-carrier-tool-shopping-bag-holder-with-key-chain-b07dnxcbyw.html)
Both these projects show that, so far, the technology has been used for people going grocery shopping - probably to not get hurt when bringing the heavy grocery bags to their car. The solution is solving the same issue as us - but the customer is different.
* Wall Bag Holder
https://makeit-loveit.com/grocery-bag-holder
This bag holder is put straight on the wall. We can grab inspiration from it in the way that we could think of such a use in the shelters. As in the homeless people would attach their bags on such an item found already in the shelters.

### Proposal n°2 : Plant it Yourself
##### Actors
:::warning
- BY WHO? We are students and we want to help homeless people
- FOR WHOM? Homeless people
- WITH WHOM? Partnership with State / Government
:::
##### Context
:::warning
- WHY? Homeless people need food and this is a way to provide their own vegetables for free by growing them. Plus it would give the streets a good visual sense of 'gardening'
- WHEN? They'll have to take care of it everyday by watering vegetables
- WHERE? In public parks, gardens, next to trees
:::
##### Features
:::warning
- WHAT? Building farming boxes that would be found in the shelters. These boxes will be filled with a sponge-like material at the bottom to keep the water, and then filled with soil. The homeless people in the shelter will be able to plant grains and grow their own food for the shelter.
- HOW? The state would provide these boxes for homeless to grow their 'farm'. Distribute them in shelter facilities.
:::
##### Usage scenario
Describe use cases
How will users access your service?
Describe scenario of utilisation, and add a drawing for each steps :
:::warning
**Initial context:**
Homeless people don't usually have the means to buy food so they just have to wait until someone provides them the money or actual food. The problem is that most of the times is not actual healthy food
:::
:::warning
**Action 1:**
Homeless person waiting for someone to give him money
:::
:::warning
**Action 2:**
Someone gives money to this homeless
:::
:::warning
**Action 3:**
The homeless takes the money and goes to buy some food
:::
:::warning
**Resolving situation:**
By having their plant growing boxes, the homeless can actually take care of their own food and eat (for free) whenever they wants real food / healthy food in the shelter. At the same time he has an occupation and something to care about.

* "Portable Farms", https://portablefarms.com/, company that sells portable stuctures to grow your vegetables indoors
* Automatic Home Growing Box
https://www.getleaf.co/
This project uses a more high-tech approach to our solution. It is also connected to an applicaiton on the phone. Our project has to use low-tech and be for shelters. Hence, we can get inspiration from this by looking at the design and possible uses, but not the actual high-tech software.
* Oak Slate Design Vegetable Box
https://www.amazon.co.uk/Oak-Slate-Design-Handmade-Natural/dp/B00ECGW5CO/ref=lp_3469851031_1_1?srs=3469851031&ie=UTF8&qid=1575038411&sr=8-1
This is a vegetable box that one can modulate himself and even write on it. We can grab inspiration in term of customization of the actual box. However, our project is for a bigger box which would be used to grow a more substantial amount of vegetables.

### Proposal n°3 : Privacy Brick
##### Actors
:::warning
- BY WHO? We are students
- FOR WHOM? Homeless people in shelters
- WITH WHOM? In collaboration with shelters
:::
##### Context
:::warning
- WHY? We want to give more privacy to homeless people.
- WHEN? During their sleep and time at the shelters
- WHERE? In the shelters, or even outside in the street - if allowed.
:::
##### Features
:::warning
- WHAT? We will be offering a brick. The bricks will be able to be stacked onto themselves to create a wall and and a private space for the homless.
- HOW? Multiple bricks are stacked onto eachother in the desired manner.
:::
##### Usage scenario
Describe use cases
How will users access your service?
Describe scenario of utilisation, and add a drawing for each steps :
:::warning
**Initial context:**
The homeless person in the shelter (or outside) lacks privacy.
:::
:::warning
**Action 1:**
!
The homeless person arrives at the shelter, is offered a bed.
:::
:::warning
**Action 2:**
The homeless person drops his belongings around the bed for the night.
:::
:::warning
**Action 3:**
The homeless person sleeps at night, but might be worried of theft.
:::
:::warning
**Resolving situation:**
The homeless person builds himself a private space with the bricks, and is able to sleep at night in a private space where he can feel more confortable.
:::
##### Benchmark
List concurrents and relative projects and describe how they relate or differentiate to your project
:::warning
* Fast house building using recycled bricks (https://www.archdaily.com/869926/this-house-was-built-in-5-days-using-recycled-plastic-bricks)
* Re-construction of a war zone with recycled bricks (https://www.sciencedirect.com/science/article/pii/S187661021101438X)
What these sources show is that there is the possibility of building temporary homes with recycled bricks. For us this means that building a small private space in the shelter or in the street, also made of bricks, would be possible and feasible.
* Everblock Systems - Creation of blocks
https://www.everblocksystems.com/
This is an interesting project as these people will create modular block (similar to lego) that people can stack together to create new private spaces. However, this is different from us as these blocks are not insulated for temperature and sound.

* DIY How to Build a Brick Wall (https://www.youtube.com/watch?v=ExltDReEdno)
* How bricks are made (https://www.youtube.com/watch?v=GEvoXuFKSA0)
These resources have taught us first the design of bricks, which is important to know how bricks can stay so sturdy and strong. Then we learned about the ways to stack them together to build a strong foundation of walls.
* Building a brick out of recycled plastic (https://www.youtube.com/watch?v=gwjhqXaLDs4)
This video inspired our group on the choice of the material for our bricks / lego. Since we're building somenthing from scratch, why not doing it while saving the planet? Or at least try not to compromise the future. So using plastic waste from oceans could be very interesting.

# P2. Test!
:::info
The goal of this phase is to improve your prototypes using end-users feedback.
:::

| Postive | Neutral | Negative |
| --------| --------| --------|
| It is useful because I carry a lot of bags around and I move around a lot, so my hands get hurt.| If I don't have one, I can figure it out myself, it isn't something major.| This one is not very confortable, with a lot of heavy bags it'll get more uncomfortable.|
The user thought it was a good idea, but wasn't so excited about it. She also says that she could lose it easily.
Make it more comfortable on the handle.
:::
##### Prototype 2 : user feedback
:::warning
| Postive | Neutral | Negative |
| --------| --------| --------|
| I like it because it gives flexibility on what I would want to plant and eat - I can plant what I want. If I had it in a shelter I would probably want to stay there longer or go there more often.| None| The material of the box isn't great because it could get soaked in the water used for the plants.|
She liked this idea the most.
Stronger and more resistant material
:::
##### Prototype 3 : user feedback
:::warning
| Postive | Neutral | Negative |
| --------| --------| --------|
| Awesome idea because we don't have any privacy in the streets and in shelters also. Building it in the way I want gives me a sense of freedom. | None| I am worried about the strength of this, whether or not it'll fall during the evening.|
She also thought that this would be a great addition to shelters. It would make her want to go to shelters more often.
Better way to put the bricks together and maybe the material too (not cardboard).

| This object could be used by anyone, not just homeless people. It is small and easy to take anywhere with me.| She asked where would these be distributed to the homeless? In shelter? Who would give them to the shelters?| It needs to be long-lasting, homeless people move around a lot and if it is not durable, it'll break too fast for them to enjoy it.|
She said it was a great idea for anyone.
Perhaps there could be a way to stick it onto the shelter walls? Giving it a second life inside the shelters.
:::
##### Prototype 2 : user feedback
:::warning
| Postive | Neutral | Negative |
| --------| --------| --------|
| Really great idea, especially because it allows the shelter to grow its own food and have the homeless work for themselves.| Some shelters do not have the space next to windows, arrangements would have to be made| Because homeless people leave and come often, there needs to be a set system for who takes care of this - there is also an issue of hygiene, the vegetables need to be handled by clean hands.|
This was her favorite idea.
She said it was good as it was because it seemed simple to build and light to carry. There could be a sort of water recycling system instored, but the sponge system was good enough to keep simplicity.
:::
##### Prototype 3 : user feedback
:::warning
| Postive | Neutral | Negative |
| --------| --------| --------|
| This is a real problem for homeless, they really would love more privacy in their lives| How durable are the bricks?| A big issue is permission, would they be allowed to build these outside the shelters? In the shelters it would be up to the shelter staff to decide how and where to build these - not the homeless.|
She believed this would be the most difficult to implement.
The product itself is good, perhaps stronger materials need to be used - and maybe even instructions as to how to build could be written on each brick.

| It seems practical, easy to use and transportable (it's small light). It seems like it could actually help homeless people carry stuff around. The design seems easy to build also.| It could be bigger to carry more stuff. Making it out of recyclable material would make it better.| They could also use it as a weapon, because homeless people get drunk and violent sometimes. Perhaps the design could be made more harmless.|
Arthur was interested even for himself and groceries.
Harmless design, recyclable material.
:::
##### Prototype 2 : user feedback
:::warning
| Postive | Neutral | Negative |
| --------| --------| --------|
| It is innovative. It gives homeless people a sense of responsibility. They have to take care of a plant, so there are many learning skills. It can be helpful.|Maintenance is important, or else the plants will die.| Homeless people might steal from the others' boxes and take vegetables for themselees.|
Theft was a big concern.
Make the homeless people able to paint their names on the boxes. It would also make it more playful.
:::
##### Prototype 3 : user feedback
:::warning
| Postive | Neutral | Negative |
| --------| --------| --------|
| I like the fact that this is about privacy. I think it's important specially for the homeless, it is humiliating for them to be exposed to the public like they are. They are able to be a bit by themselves, they can relax and be at peace. It is good that it is optional, so they are free. It seems low costs and easy to design | It might take a lot of space in the shelter.| The shelter is about bringing people together, so too many of those bricks could take out space that could be used to add a bed for another homeless person.|
Perhaps thinner bricks to give more space to others and adding a sort of instruction kit to teach them how to use it.

| Handle idea is a very interesting proposition but not creative enough. It should be different from existing handles | The shape of the handle should be improved. This handle could be circular with a lock on one side so they can fix their bags |Homeless people usually carry all their belongings with them, this handle is too small for them to take all their belongings and the handle can't afford heavy stuff. It's better to use a shopping cart than a handle|
We need to improve the design of our handle so it can afford heavy belongings.

| --------| --------| --------|
| Vegetable box is a good idea which can give an occupation to homeless people and help retrieve the light of hope. | It will be better to give them the vegatable seeds at the same time | Cultivation is a very complicated process and requires one kind of special knowledge. Even the farmers are not sure that they can get stable harvesting results at the end of the year. What can the homeless people eat if their plants die after one month of their cultivation? The failure can even damage their confidence badly.
|
We can put some instruction cards on the box or hire someone to teach homeless people how to grow vegetables.
We can also provide the vegetable seeds to the homeless people.

It is better to make a rubber or plastic one| This handle is so general. you should differentiate it between homeless women and homeless men since they have different force and size of hands|
we should do some weight tests for our handle and figure out the maximum weight it can bear. We can also change the material from wood to plastic.

| The most important thing for them is to avoid starvation. Vegetables is a good choice when they want to improve the eating habits.| homeless people move a lot. It will be better if there is an agency in the shelter that can take care of the plant box . | Cultivation takes a lot of time. I don't think homeless people can spend one month or even longer taking care of their vegetables. Most of the vegetables need at least 5 months to grow up. Homeless people need something quick and anti-hunger like bread , rice.. |
We can put the plant box in their shelter and there will be someone specialized in agriculture regulary taking care of the vegetables.

| This is a really good idea, I like it so much | Those bricks are still not convenient to carry around even if they are light. Maybe you should put the brick at a special place in their shelter and ask them to put it back when they move to another shelter | no |
We should think about the distribution system of our bricks since the bricks take a lot of space and homeless people are not willing to carry them at all time.

| That is an easy and simple proposition | The egg packaging is a good idea if you want to put the brick inside the shelter | you need to change the polyfoam into some endothermic material. The fabrication of the brick will cost you a lot of money since you need to have a great quantity of bricks|
we should keep the egg packaging form and change the material into plastic .
idea: we can use 3D printing to make it

### 4. Select the most promising proposal
Describe below the selection process of the most promising proposal :
:::warning
After analysing the feedback of all interviews, we understood that the majority of people showed a special enthusiasm for the third proposal:the privacy bricks. The process of choosing this proposal was quite easy, since it was also our favorite idea since the beginning.
Nonetheless, our process was the following:
1) We decided to listen to each interviewee's feedback in all 3 proposals in an equal way. We were impartial, in order to not influenciate answers. In addition to that, we put the same effort in trying to improve all 3 prototypes for the second round of interviews.
2) After the second round, answers were quite harmonious, plus two of the interviewees didn't even have a negative aspect for the privacy brick.
3) Lastly, we came to the conclusion that the most promising proposal is the third one: the privacy brick.
:::
:::warning
* The bricks represent an acurate way of solutioning a big problem in the homeless community: the sense of privacy. With our bricks, people will be able to separate their private space from the others in a very flexible way: they can choose the layout of their "wall" and the quantity of bricks they want.
* Advantages: It is the most feasible idea (out of the 3); answers a real problem (the handlers and the vegetable box are just a "plus", not a solution).
:::
Describe below what are the features of your final project :
:::warning
1. Bricks that protect from both sound and temperature
2. Lighter weight than regular concrete / clay bricks
3. Each brick has dents in order to stick to other brick and form a wall, without using cement mixtures or glue - this way all bricks can be re-used.

## Make your final prototype
:::info
Now that you have defined what is your best proposal it's time to make a greater version of it. You will present it to the jury during the final evaluation alongside the early prototypes made in the previous phase.
:::
:::success
A good prototype is self-explainatory : the user must be able to understand how it works without instructions or user manual. It must be fully functional and sufficiently strong to withstand several demonstrations in real conditions of use.
:::
:::danger
For this phase it is **mandatory** to use at least :
- The **laser cutter** and/or the **3D printers** to build your physical “shell”
- **Arduino** electronics and/or **Adobe XD** to make your prototype interactive.

* http://carrefour-numerique.cite-sciences.fr/fablab/wiki/doku.php?id=projets:generateur_de_boites
We used this site to generate the adobe illustrator design of our brick.According to our precedent design, we finally generated brick as length: 270mm, width:200mm height: 70mm
* https://www.fab-brick.com/
Thanks to this site, we decided to fill our brick with plastic bags and clothes.
We decided to contact this company by e-mail to share our brick design and ideas, and to ask for a possible partnership. Unfortunately, we still didn't receive their answer.
Our main idea, if time allowed, was to use recyclable materials, like clothes or plastic, to build our bricks. Since we are treating such a fragile and human issue, it wouldn't make any sense to build these bricks and producing waste. So sustainability and re-used materials are the core of our idea for fabrication.

### Demonstrator design
#### Drawing
:::info
Start by taking a sheet of paper and draw the global shape of your demonstrator, then explode it into the parts that compose it and draw them one by one.
:::
Insert below the pictures of your drawings, don't forget to write a caption for each image :
:::warning
Main picture : global drawing of your demonstrator
Here we can see the two main parts of the brick: the actual brick (the rectangles in the middle) and the egg boxes to put the bricks together. Hence, in the picture above we can see four bricks together.
:::
:::warning
Part 1 drawing
The first part is about the outter part of the brick. Indeed, above we can see the egg boxes that will be stuck around the brick.
:::
:::warning
Part 2 drawing
This is the brick itself without the egg boxes. The materials to be used will be either plastic or wood.
:::
:::warning
Part 3 drawing
The third and maybe most important feature of the brick is what can be found inside. Inside there will be recycled garbage (plastic or clothing), which will help the brick be sound proof and insulating.

Do the same for each part of your prototype

___
### Conception
- Use Adobe Illustrator or TinkerCAD to design your parts.
- Use Adobe XD and/or arduino to design interactions
:::warning
Insert here screenshots and / or links of your 2D and 3D files and write a caption for each screenshot

### Building process
Describe below the building steps of your demonstrator and insert a picture for each step :
:::warning
**step one** : Above we can see the brick in wood, done by laser cutting and then putting the different faces of the bricks together. Then, inside, we see the recycled plastic, for insulation and sound-proofing.
:::
:::warning
**step two** : The egg boxes are stuck onto the bricks. This is make it possible for the bricks to be put together. The egg boxes are a unique feature because it will also give an aspect of sustainability to the brick.
:::
:::warning
**step three** : The bricks are then sprayed into a brown color.
