Recycling motors of broken E-scooters to make an Electric Wheelchair Assitance Kit (EWAK).

0

The pollution created by adults scooters ss a huge problem in Prias.THe society does not take them bak to recycle them. Moreover a lot of themare found in the river, La Seine, in Paris. 

Moreover, motorized wheelchairs are expensive for the majority of the population (between 700 euros and 3000 euros) and represent and important investement. 

We had the idea to start to customise your own motorized wheelchairs, starting from normal wheelchair (around 100 euros) and incorporate the batery of the adult scooter. 

This project will allow a person to create his own wheelchair with the guide book that we will make and at a low cost. At the same time the adults scotter will have a second life.

If we have time, we want to incorporate some functionalities into the wheelchair like drawer, liitle table, place for a glass,...

1) Electric wheelchairs are too expensive

2) Broken E-scooters are left behind in the street or in the river / are not recycled

General Feedback - Winner of our challenge for this week

 What you liked ?
I like the idea about scooters a lot and I've seen the problem myself in London and
elsewhere.
The problem and the solution were very good described
Their areas of opportunities ?
My guess is that e-scooter companies would be very pleased if you help them with their
waste disposal and for good purposes.
Their strongest moment during the presentation?
The challenge slide about the scooters
Showing the problem of scooters in Paris

We worked on different little project in order to open our mind each other :)

We discovered ourselves by lunching together, doing projects and finally we decided to work on the same idea. 

We have chosen our name 10 min before the first pitch. Naturally Hybrid Thinkers came us as the best choice !

Feedback from the jury - Winner of our challenge for this week⭐️⭐️ 

 

● Love the concept. Not sure if it will really work precisely as you describe but it it is
a fantastic concept that could set a new trend to "upcycle" the new trendy
products for the good. Great team slide . Try to also identify who your
stakeholders are- you may be able to identify interesting stakeholders that can
fund these types of solutions (i.e. on City level.
● A good documentation at the end of the project will be need good work !
● good energy

Hi! We are Hybrid thinkers currently working on our project EWAK at CRI in Paris for the 5 of us!

We have another member, Habiba, working with us from Nigeria.

We are happy to present you the engineering and technical team of the project !

Doriane and Fosco are working hard on the prototype. They learned how to turn on the motor and how to fix it onto the wheelchair.

They’re doing an amazing job !

Here is the sponsorship and communication team !

Alexia, Konstantin and Laure are developing the project by contacting stakeholders, establishing the business model and managing social medias.

Check out our instagram hybride.thinkers to follow the advance of our project day by day !

Our team had the opportunity to include a new participant in the middle of the project. Habiba brought us a new perspective to our project. She is from Nigeria. She gave us  an idea for an alternative to scooters: abandoned scooters are not readily available in Nigeria. Her idea was centered around the use of an external DC motor (a direct current motor is basically a machine that converts electrical energy to mechanical energy in a bid to generate movement and there are ready-made motors designed by many different companies). This motor will have an output that connects to hinges which will hook the center of the posterior wheels helping to propel the wheelchair instead of the use of hands. This motor will be powered by a battery which will be charged using solar energy. The battery will be attached under the chair and the solar panel will only be attached for charging. This price of the kit is projected to be about 1/10th of the amount of an electric wheelchair in Nigeria.

The main problems identified in Nigeria is that there are millions of people subjected to permanent and temporary use of wheelchairs and while those who need it permanently are better off with the electric wheelchairs, they just can't afford them. For those who propel themselves with their hands, they are subject to a lot of side effects over the years, most of which are shoulder dislocations, blisters and sores on the hands, joint pains and so on. 

From the interview Habiba had with a couple of patients in Nigeria, it is apparent that they all love the idea however, many of them would welcome the idea better if there is a working prototype that shows it is really a technology that works.

Our name comes from the team’s spirit. According to the Cambridge dictionary “Hybrid” means something that is a combination of two or more other types. The goal of our project is to resolve two problems by finding a solution. “Thinker” expresses a person who thinks, especially deeply and constructively. Indeed, we love to brainstorm together, share our ideas and express our different points of view.

During this week, the city of Paris released the 3 winners of the call to project between 16 of them.  We contacted the winners. Dott & Tier Mobility gave us good feedbacks. They said their were interested about our project. They said they are gonna contact their superiors & marketing directors.

Document ourselves on wheelchairs and how to tear apart an electric e-scooter.

We went on the streets to collect broken electric wheelchairs.

We started with a small model of the wheelchair. This model made us work on different aspects of the project.

The first aspect was : how are we going to be able to control the motors? We did the code for the two motors, by using the software arduino. We tried the code on two motors of a broken drone: the advantage is the small size of those motors, that we can place in a model. The program will be the same as it was for the motors of the e-scooter.

The issues that we faced here were controlling the two motors at the same time and finding a way to be able to turn the wheelchair by the rotation of the motors.

The second aspect : understanding how to fix the motor in suspension on the wheel of the wheelchair.

We thought about making a frame to link everything.

We continued to make the model. We cut all the parts of the wheelchair 3 times smaller than the normal one.

To link the engine (in the wheel of the electric scooter) to the wheelchair, we imagined a frame. We designed the frame in fusion 360°. The piece that we created was cut with the laser cut.

We had a few issues with our model. First of all, our model was difficult to build because the wheels were not rolling well with the cardboard. 

Secondly, we had to balance the weight. We don't want the wheelchair to fall because the frame is too heavy in the back. To solve this problem, we put weight in the front of the wheelchair where the battery will be.

Finally, the model was finished and the motor was working so the wheelchair could now go forward.

Making a model was great to understand certain issues we will face for the real size prototype and to get a better idea of all the construction thus we started the realisation of our prototype. For our prototype, we encountered some problems. The materials were hard to find. The extrusion in aluminium was not delivered for one week. So we decided to do a first prototype with pvc which is the cheapest solution. Moreover, all the connectors we needed were not available. However, we found a solution and decided to make our own connectors with the software fusion 360°, then we print it in 3D.  We print 4 of them and they fit perfectly the structure of the wheelchair.

We contacted stakeholders : e-scooter companies, the Paris town hall, associations. It was sometimes difficult to reach them, but by the end of the week, we got great feedback and an association invited us to visit their workshop in Angers. The french network of fablabs agreed to help us spread our open source plan and some e-scooter companies agreed to give us motors. We started to work on the business model of our project, and see how the project could come to full fruition.

We did a model on scale 1:3 in cardboard with little motors from drones in orders to reproduce the action of the motors of the e-scooters.

Our first model didn't work well, we needed to unsterdand how the motor worked and where to fix it on the wheelchair.
