Brief
The challenge is the development of an ambulance that ensure the safety transport of patients from their households to the nearest clinic, day and night, in both wet and dry season. The project is going to be used in the Sunderbans region (West Bengal, India).
INNOAID.ORG
- Use of local transport
- Man powered
- Carry one patient and two attendants / relatives (3 people)
- Protection from climate changes
- Shock absorption
- Repairable at any time and anywhere
- Provide health service (Oxygen, saline fmuid, stretcher,
shade, bucket)
- Easy transportation of patient to and from the rural
ambulance
- Low cost (11,000 INR = 175 euro)
Brief DESIGN REQUIREMENTS
Need higlighted by Doctor Amitrava, working in the health clinic founded by JGVK.

Concept
help the driver to ride!
The goal is to offer the opportunity for the second person to ride, so that the ambulance can go faster, WITHOUT compromising the monitoring of the patient save the energy needed to move the ambulance
A B
Selection of criteria in order of priorities
- 1. patient care
visual inspection by the driver: always
- space (on the stretcher ) for physical assistance
- 2. dimensions
- width=max. 1m -road-
- length=max. 3500 -current VR-
- 3. maneuverability
position of driving forces
- visibility
- 4. effjciency
length
- and accessibility to the chain
perpendicular
- cycling

Concept
This confjguration offers:
- Visual inspection and a physical accessibility to the patient by
the driver in A when the parent is cycling in B o is sitting in C,D;
- Possibility to sit next to the patient(2people: C, D);
- The general dimensions are set in relation with the width of
the street (not more then 1 m) and the length of the transport unit (not more then the standard V.R)
- A shorter inferior chain provides less energy losses during the
ride and it’s easly repairable if it came out from the “rails”;
- The positions of the 2 riders (A, B) are on the central axis.
This provide a higher level of effjciency during pedalling. On the other side: The visibility is limited due to the position of A and B in relation
- with the front cover structure.

stretcher extraction (short side) cover saline solution (1m) visibility
Concept FIRST POSSIBLE POSITION OF THE PATIENT
350 400 1000
This confjguration prevents the extraction of the stretcher on the long side, due to the presence of wheels. In addition, the placement of the stretcher at a low rise (about 35 cm) is much more uncomfortable to extract.

Concept SECOND POSSIBLE POSITION OF THE PATIENT
By choosing a smaller diameter for the front wheels (50 cm) is possible to place the support structure for the bed with an about 70 cm height, making the extraction from the long side possible and at the same time requiring less effort for those involved in the operation. We went on with this confjguration.

The stretcher is made of a frame in wood and the inside part in textile in a way to keep it lighter. The extraction take place from the left side by three handles.

Parents, Patient and Driver Process Idea
INNOAID.ORG Process Idea With this confjguration the patient is controlled even if the parents decide to cycle.
INNOAID.ORG Process Idea The ambulance can transport max 6 people : 3 on the bench, 2 drivers and the patient. The covers of the two drivers can be extract from the bottom of the cover.
INNOAID.ORG Our main focus during the design process was the patient. We started the process trying to understand which would be the best position of the patient in relation with the
- driver. After the analysis of the different possible combination we found out that putting him in front of the driver
was the best solution. The other our main concern was to use the third person to help to drive. We provided a second location to cycle behind the driver. According to the condition of the patient and the roads, the relative can decide if help to run or assist the patient. The bench allowed also to carry more than one person. We know that this is a concept and many things have to be added or changed. The mechanism to rotate the front wheels has to be designed. We know that this system could work but we stiil can’t understand how it works. Here are some video of other vehicle that use the same principle. http://www.youtube.com/watch?v=A3XUb5Rn948 http://www.youtube.com/watch?v=aTE6irdDSus We don’t know yet all the tecnhical stuff like the diameter of the tube, and we should make some structural calculation to know exaclty if the structure is stable. We miss some details like the light, the bag for the instruments and probably some mirrors to improve the visibility, but this are things that could be added in a second time. Process Idea
INNOAID.ORG During the process we realize that this one is not the only possibe solution that can be done, but we went straight
- n this because we think it answer at all the requirements of the brief. Of course, it still needs some improvement.
