## Define & prototype 3 proposals

### Proposal n°1 : Landing Net

##### Actors
:::warning
- FOR WHOM? For kids,children and young teenagers
- BY WHO? Basse Adja Nayette Diouf, Emmeline Carrié, Zhao Huacheng, Sarah Castanou, Anna Monmarche
- WITH WHOM? Try to involve/ sensibilize other students and children.
:::

##### Context
:::warning
- WHY? We want to create this prototype in order to sensibilize the young population about the issues/ dangers of water pollution. It is time that it decreases because it is killing marine life and it is not only affecting them but also us humans. If our target start being more conscious and aware about these issues and start using the prototype it will be a total success for us.
- WHEN? Spring- Summer (March-July)
- WHERE? Beach, they will be able to use the prototype whenever they will go to the beach during the summer for example to clean the ocean. Therefore, these actions will also have an impact on the other people (adults) going to the beach.
-
:::

##### Features
:::warning
- WHAT? two wooden handles, like on a diabolo, with two strings connecting the two handles to a bucket with holes in it that will let water but not waste to pass through
- HOW? Define the key actions, clarify the give/get relationships and how the actors connects.
:::

##### Usage scenario

Describe use cases
Users can access to this prototype through an application or a game that would encourage children to collect as much waste as possible.

This is an improved landing net which is practical to use on a boat or over water, less physical than a normal landing net (which is used only with one arm), and more stable for children.
:

:::warning
**Initial context:**

Take the two pieces of wood in your hands
:::

:::warning
**Action 1:**
(
)

Approach and place the plastic jar in the water

:::

:::warning
**Action 2:**

Exert pressure while backing up and keeping the jar in the water, so the waste will be collected along the way on the beach
:::

:::warning
**Action 3:**

Carry the container on the water to collect the waste.
:::

:::warning
**Resolving situation:**
Place the plastic container on water so that it will float and collect the waste.
:::

##### Benchmark

List concurrents and relative projects and describe how they relate or differentiate to your project
:::warning
* Regular Landing net,this is a normal landing net, it is linked with our project because we use the same principle which is a prototype that let water to pass but not waste. However, our project is different because it will be customized with homemade products and be less practical than a regular landing net since ours will be more focused on our targets which are children; therefore, it will be suitable for children.
* Fishing Net, the link with ours is the net,however, this is only for fishing. Therefore, it is somehow different from ours which is to captivate waste and not fish.

### Proposal n°2 : Hand shaped pliers

##### Actors
:::warning
- FOR WHOM? For kids aged up to 10 years old.
- BY WHO? CARRIE Emmeline, BASSE Adja Nayette, MONMARCHE Anna, CASTANOU Sarah, ZHAO Huacheng (design & conception)
- WITH WHOM? With the help of environment specialists (direct or indirect contact) and our project tutor who will help us for the conception part.
:::

##### Context
:::warning
- WHY? Through this playful object, we would like to revolutionize the approach of kids towards environment and ocean preservation. By making this object playful and attractive, our goal is to encourage kids to clean the oceans and raise their awareness about ocean pollution.
- WHEN? Mostly during the vacation since it is a period when kids are free.
- WHERE? Around oceans, seaside areas and more generally in areas where water is a renewable energy (not a pool for example).
:::

##### Features
:::warning
- WHAT? Hand shaped pliers to catch waste with a transparent stick people can draw on and customize, designed for kids. This object shall result in a positive future impact on childrens awareness towards environment and ocean pollution. Thanks to this object, the next generation will act more for the environment since habits would have been taken since their yougest age.
- HOW? The hand shaped beak is supposed to catch waste of a certain size alon the seas in a funny and playful manner.
:::

##### Usage scenario

Kids can access the hand shape pliers through a website, an application or game allowing them to be able to use this tool.

It works like a gripper machine in the fun fairs, to make the collect of waste a little more fun, we put a hand instead of pliers. At the of the stick there is a trigger and by pressing it, the hand closes automatically so that you can catch the waste.

:::warning
**Initial context:**

Start by grabing the stick in the direction of the sea
:::warning
**Action 1:**

While having the stick in your hand just target a waste

:::warning
**Action 2:**
Once the waste is targeted, place the stick on it so that the hand can be above the waste and be ready to close it
:::

:::warning


You placed the hand properly above the waste, now by pressing the trigger at the end of the stick, close it so that it can catch the waste

:::warning
**Resolving situation:**

Now make sure the waste is well caught by the hand, and put it in a plastic bag with all the others garbage caught
:::

### Choose the most promising proposal
Compare the three proposals and select the one you think is the most relevant with regard to these 4 criterias:

- Is this proposal relevant to the course theme? (Fix our future with digital fabrication)
- Is this proposal relevant to the group's subject?
- Can I materialize this proposal on a scale of 1:1 at the makers' lab?
- Does my proposal respond to a real need?

At the next meeting you will argue your choice with your tutor, she / he will choose the proposal you will develop in the next phases.

:::warning
Ocean cleaning experience for kids using low techs
:::

:::warning
**Describe below why you selected this project:**

We selected this project because it is a hot topic in the 21st century and we want to spread awareness around this topic and give existing solutions. In fact, people will know that there is no need to have sophisticated materials to reduce ocean pollution only a simple gesture can improve things. Moreover, this is also why we focus more on the young target (children) since they are tomorrow's adults.
:::

* * *

### Define your dream product

You and your tutor have chosen the best proposal, before testing it with users you need to refine this proposal.

:::warning
- What is the purpose of your product?
Initiate children towards the water pollution in today's world through low techs.
:::

:::warning
- What problem do you want to solve with it?
Sensitize children and spread awareness around water pollution especially in the ocean so that they will be aware of this problem and be eco-responsible since they are the adults of tomorrow.

# P2. Test!
:::info
The goal of this phase is to improve your prototype using end-users feedback.
:::
:::danger
**Negative user feedback doesn't means your proposal is bad** : do not give up and analyse what are the pain points to solve in a new version.
:::
## Test and iterate your proposal

### 1. Test protocol

Write below your test ptotocol :

:::warning
**Write here the ideal user profile (persona):**
For our project, the ideal user profile would be children or very young teenagers (10-13 years old)
:::

:::warning
**Write here the goal of your test:**
The goal of this test is to sensitize the young population about the issues/ dangers of water pollution via the use of a fun and playful prototype that they can use easily which is a landing net.
:::

:::warning
**Describe here the main feature you want to test:**
Through this prototype, we want to test how it will be conducted when children use it (will it be easy to use or not? Are they going to enjoy it? or Is it going to be too difficult for them especially with the woods in their hands). Therefore, we will test the feasibility of the prototype and their satisfaction.
:::

:::warning
**Tell who will be conducting the tests (at least two persons per test):**
We chose children as testers : they are Sarah's little brothers, aged from 10 to 16 years old.
:::

:::warning
**List and clearly describe all the actions that the user will have to perform to test your product according to your usage scenario:**

- The tester will be showed a first video of Emmeline catching waste with our prototype
- The tester will give his opinion on 3 points : the feasibility, the satisfaction in terms of design and interest the object triggers for kids, and the effeciency
- Those feedbacks will be reported in the HackMD file
- Emmeline will adjust the prototype depending on those feedbacks
- A second testing will take place under the same process
- Emmeline will be able to produce and finalize the last prototype

Describe the evolution of the prototype:

- Replaced the elastic threads by "elastic bungee cords" for more solidity and less elasticity..
- Replaced the wood ends by an eternal rose sawn in two for more solidity and better waterproofness
- Added tape around the rose to make it bigger, stronger and more flexible
- Put tape to hold the rose tips to the elastic threads for a good support
- Replaced the small plastic pot with the inside of a salad spinner. Indeed, it's bigger, has many more holes, is easier to handle and goes through the water much more easily
- Kept the same size metal screw that I also taped at the bottom of the container
- Passed the other ends of the elastic bungee cords through the two large holes at the ends of the container and then closed the ends of the cords with pliers
- To finish, we thought it would be nicer if we shorten the elastic bungee cords by hanging them up one after the other as shown in the attached pictures:This makes them even more stable and easy to handle. Moreover, it is more suitable for children's size.

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 :
- **Tinkercad** to design in 3D your product
- **Tinkercad Circuits** to design the electronics
- **Adobe XD** to make your prototype interactive.

Note in the section below all the projects and tools you've find to help you for the conception and fabrication of your final prototype.
:::warning
* **TOOLS:**
* Tinkercad, https://www.ladn.eu/entreprises-innovantes/techforgood/projets-inspirants-techforgood-developpement-durable/ The materials used in order to build those low tech solutions to preserve the environment actually made us realize that very simple materials like wood or plastic can create big changes within our environment.
* Arduino, we used this app in order to bring more esthetic to the final prototype and most importantly for it to be more playful and useful for the kids especially with the 3 different lights they will detect exactly when the prototype will be filled or not with rubbish.
* Adobe XD, https://xd.adobe.com/view/db909d52-43a3-4e7a-52b8-829f7a4509fd-ada1/#access_token=eyJ4NXUiOiJpbXNfbmExLWtleS0xLmNlciIsImFsZyI6IlJTMjU2In0,creation of an application in order to guide kids on the usage scenario of our prototype and also to make it more attractive and suitable for the children.
* New container: which is more attractive and useful than the previous ones. Consequently, this helps with the maneuverability of the prototype.

### 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.
:::

Drag-n-drop below the pictures of your drawings, don't forget to write a caption for each image :

:::warning
Those 3 drawings are meant to show the object and its system of functionning in its globality : the plastic recipient is decorated with childish shapes under the theme of the universe, and the object is solid thanks to this system of ropes attached to wood handles.
:::

:::warning

This drawing shows the inside part of the recipient with the wholes, the handles and the shapes that are big enough to be visible on top.
:::

:::warning

The second drawing put the accents on the shape on top of the recipient. Indeed, shapes will be added in order to attract our target and make it enjoy the object, which will therefore encourage kids to use it.
:::

:::warning

This drawing shows the top part of the recipient, as well as the ropes and the wooden handles that are supposed to hadnle it. The drawing aims to show the object in its globality.

:::warning
Do the same for each part of your prototype

### Means of fabrication

:::info
Now that you have designed your final prototype it's time to build it! Take the time to fill accuratly the following section to have a good overview of the building process.
:::

#### Tools

List below what tools you need for building the project:
:::warning

* drum sticks (made of wood)
- pink / green / yellow tape
- green and red "sandow tenders"
- a large pink colander
- badian flowers
- a blue funnel
:::

#### BOM (Bill Of Materials)
List in the table below all the elements you need to build your demonstrator (replace the exemples with your parts) :
:::warning
|Part number| Part name | Material /description | Dimensions |Quantity |
|-----------| ----------- | ------------------------ | -------- |----- |
|1 |Drum sticks | Oak wood | 40cm x 15mm of diameter| 2 |
|2 | Ropes | Polyester and specific fibers | 50cm x15mm of diameter | 2 |
|3 | Plastic recipient | TinkerCAD | 174x150x163 mm| 1 |
|4 | Small colored LEDS | Arduino Uno | N/A |3 |
|5 | Small black fasteners | Plastic | Lesss than 50mm x 50mm | 4 |

### Conception

- Use **TinkerCAD** to design your parts.
:::warning
This screenshot shows the outside and the top shape of the recipient. It aims to show the recipient in a global way : the color is blue, in link with the theme of the universe, and we made the choice of making the recipient as big as we could in order to answer the requests of the kids.
This screenshot shows the inside of our recipient. As one can see, wholes have been made everywhere and in an equal way so that the catching can be efficient. Moreover, handles have been added to facilitate the assembly with the ropes.
This screenshot shows the upper part of the recipient. Indeed, shapes have been willingly added in order to make the object catchy and playful for kids. Additionally, there is a scripture "Prends soin de ton univers" to make a play on words : the theme around the recipient is the universe, and at the same time, the object helps taking care of the oceans, which are part of the universe.
