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

:::

* * *

### 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?
The purpose of our product is to recover the cold water that flows at the beginning of the shower before the hot water arrives. This cold water is wasted when it could be used for another purpose. We want it to be used for the toilet. This water limiter will allow a pipe from the shower to the toilet to send the cold water to the toilet and when the water is at the temperature desired by the user the water will stop flowing through this pipe and will be directed to the shower outlet. There is also a water tank next to the toilet to store all this water, as the toilet cannot hold all this water

:::

:::warning
- What problem do you want to solve with it?
The problem we want to solve with our water limiter is simply to avoid wasting water and reduce consumption of each members of the family.

:::warning
- What features your product will have to achieve this objective? Rank the features in order of importance
- main feature : Technology to change the direction of the water when the water temperature is right

- second feature : The hose that connects the shower to the toilet

- third feature :The water tanks

### 3. Improve your prototype

:warning: <span style="color:red">**Drawings, illustrations and other images are not allowed.**</span>

:::warning

Drag-n-drop 3 pictures below :

:::
:::warning
Describe the evolution of the prototype:

We understood and heard the recommendations to improve our prototype. That is why we have added a screen to indicate the volume of water available per shower. This volume can be changed with the "-" and "+" buttons, as well as the temperature. This will allow a better visualization of the consumption of each person and to save more and more water.
We have also added a water tank, allowing to contain the cold water recovered directly from the shower. This will allow us to store a larger volume of water because the toilets would not have been able to store it. As for the dangerousness of the cables, there is no fear to have, they will of course be hidden in the walls of your house and will in no way be visible. It will look like your washing machine. And as for the installation which seems difficult, it is normal. A technician must come and install it, as well as the water tank and all the pipes that connect the shower to the water tank and from the water tank to your toilet.

##### Prototype video
Use your smartphone to make a short video (30s) showing your improved prototype in situation of use, and post it on the Slack channel of your group.

##### User feedback
3 main issues raised by the user:
- potential expensiveness
- potential issues with repairing (in case of the product breaking down it will be hard to repair it considering that the technology is very innovative)
- it is always risky to try new technologies, that are not commonly used

| Positive | Neutral | Negative |
| --------| --------| --------|
| The idea seems very interesting and relevant to the modern environnemental problems. It is very important to work on solutions of these issues, especially for younger generations. As for the idea itslf, it represents the product of the future, it is great!The problem you are looking to solve is actually very important and unfortunetly not a lot of people understand it. | - | As for potential issues you might face while developing this product: high price due to elevated production costs, the risk of people being afraid to adapt new technologies in their nousehold, difficulty to manage in case of a break down due to lack of competent professionals familiar with the technology|
:::

:::warning

#### General comment on the interview
The interviewee found that the problem is of current interest and the prototype is a good solution to it.
:::
:::warning
#### Features that need to be improved
It is important to reduce production costs to its minimum in the future, to try and make its functoinality easy and clear and to ensure a quality marketing of the product.

### 5. Define your final product
According to users feedback rewrite your requirements specification.
:::warning
- What is the purpose of your product?
The purpose of the product is to make the use of water heating energy more efficient thank to the smart grids technology. We present you the product of the future: the global trend of economizing energy and resources is embodied in our project. More precisely, it allows users to economize water wasted while waiting for the water in the shower to heat to the comfortable temeperature level. This solution will significantly reduce the consumption.
:::
:::warning
- What problem do you want to solve with it?
We want to solve the problem of useless and unjustified water consumption for families. Finding a way to use this water usually wasted all around the world would be a perfext solution.
:::
:::warning
- The features our product is equiped with:
- temperature measurer
- water tube sending water to the other direction
- water tanks

# P3. Design
## 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 :
- **Tinkercad** to design in 3D your product
- **Tinkercad Circuits** to design the electronics
- **Adobe XD** to make your prototype interactive.
