The Situation: Oxfam needs design solutions now to solve unique problems that occur during humanitarian emergencies; traditional design & procurement processes are inefficient. The Solution: Bespoke products that can be designed for the specific problem and quickly tested in the field. The Execution: iMakr will facilitate through MyMiniFactory platform peer to peer collaborative design and 3D Printing by calling on your time and skills.

Project One - Hand sanitisation Stage Two: Hand sanitisation is a serious problem where water is in short supply. Children are especially at risk from disease and illness in this type of Humanitarian Crisis. Designs now need development to help find a solution to the problem - scroll down for our design review including ideas on how to develop and design your ideas.

Design Review We received many great designs for stage one of the Oxfam project, here are a few examples that show interesting ways of thinking to achieve points on the previous specification to help you develop and design your ideas.
Sandino Torres:
The designer of this tap has really thought about user interaction and hygiene.
This design is a great examples of one touch design. This improves hygiene as the user need not touch the dirty tap with clean hands to stop the water flow.
Room for improvement:
The design's mechanical properties need adjusting to ensure the product works effectively, for example, the handle may be too thin to have pressure applied without snapping so this will need strengthening.
Joe Palmer: This is another example of the one touch method of use. This designer has also thought about a hygienic way to hold the soap - it is placed in clear view above the tap reminding people to use it. Room for improvement: This design consists of too many parts that could cause leaks and cause the design to have a complicated assembly process. This needs simplifying to bring down the cost of production and ensure a leak proof product.
Michael Rew: Going further than the one touch method of interaction, this designer thought of other ways to interact with the design to ensure its use is hygienic. He thought of a really interesting method that uses the wrists instead of the hands allowing the design to be as hygienic as possible. Room for improvement: The size of this design will incur large production costs, perhaps the no touch technique can be applied in a different way to work with other water containers and make the design universal.
Peter Krige: Remembering the low water pressure and cost of manufacture, this designer came up with simple and easy to use ways of controlling water flow to eliminate waste water and keep the cost of manufacture and transport to a minimum. Room for improvement: This design requires the use of a bike pump in order for it to function properly, this is impractical as bike pumps are expensive. The design needs to be able to work with low water pressure to eliminate the need for large extra parts.
Sergio S Ferreira: As well as also using water pressure and being a simplistic solution, this designer made it foot operated to maximise hygiene. Room for improvement: The pedal needs to be larger to help with its stability, there may even need to be a way to attach it to the floor to ensure it is not kicked over or broken. Remember these products will be used in large communities and will need to be robust.
Onno Van Der Neut: Clean water is in short supply so every drop counts, this designer has found a great way to stop people wasting water when washing hands. As well as saving water, he has thought about attaching the design to many different types of water containers to make it universal and how to use gravity as the pressure source in the design. Room for improvement: Parts of this design could easily get broken or snap, the cable needs revising to be stronger and maybe a solid part. There may even be a way to reduce the surface area the user needs to touch which would improve the hygiene aspects as well.

So how can you help? You can download the design specification here. Submit your design before 18/07/2014. Our engineers then review all the design entries, and identify a short-list of variations to be field tested in Lebanon. We will run through several iterations of this process until we have a suitable solution ready for mass manufacture by September 2014.   All contributors will receive full recognition for their efforts on MyMiniFactory will provide regular updates on the progress of the project - from design specification to delivery.
