Prototyping

Prototyping Bwere, Daniel E. A prototype is a draft version of a product that allows you to explore your ideas and show the intention behind a feature or the overall design concept to users before investing time and money into development.[1] Prototyping is the fourth phase in the design cycle that lets the design team develop quick practical concepts about their brainstormed ideas for testing before resources can be spent in developing the final product. “They slow us down to speed us up. By taking the time to prototype  our ideas, we avoid costly mistakes such as becoming too complex too early and sticking with a weak idea for too long.” — Tim Brown, CEO & President of IDEO Types…

Coding and challenges

“It takes two flints to make a fire”, this saying defines the mood of this week. It all started with the Arduino basics, which to somewhere new concepts. We were given a brief introduction to Arduino (Arduino Uno to be specific), its pins (analog and digital pins), how it works, the power pins and the power that Arduino accepts. We also learnt about  how it can communicate with the computer. We were given a brief on how to write codes in Arduino in order for it to communicate with the computer. “Comments, comments. I need to see some comments” this is what our Supervisor (design studio manager) encourages us to do when writing the codes. She says comments are important…

Getting familiar. Time to learn new things

GETTING FAMILIAR… This week was a little bit challenging because most of us were not familiar with the learning environment. Most of us came with our own expectations but upon arrival, it was so cool and fascinating at the same time, to meet new people with almost similar and different expectations from me. Getting to know new people and their ideas is the most amazing thing about this first week. Upon arrival we were told that it was possible to turn our ideas into reality, this motivated me into wanting to learn more. In the process we started working with the CAD program (Fusion 360), laser cutting machine and 3D printer. When we were introduced it was a bit of…

Deep diving. On needs findings from different hospital.

Deep diving … Just like Margaret Heffernan (entrepreneur and writer) once quoted “for good ideas and true innovation, you need human interaction, conflict, argument and debate”. This week was all about the needs findings for which we paid a visit to two hospitals i.e. Muhimbili National Hospital (MNH) and Comprehensive Community Based Rehabilitation in Tanzania (CCBRT). It was really an interesting week, getting to see what the doctors do and the things they need. Muhimbili needs finding We paid a visit to MNH and went to the Pediatric Intensive Care Unit (PICU)  with the doctors who explained what they are doing and the challenges that they are facing. There were various triggers that we noted from the Muhimbili visit, and…

Getting started. Data analysis from the needs finding

Getting started… This week involved analysis from the needs findings that we conducted last week. We listed all our needs findings from the hospital visits at Muhimbili national hospital (MNH) and Comprehensive Community Based Rehabilitation in Tanzania (CCBRT). These findings made the rise of final projects such as bubble CPAP, wall suction machine, automatic chest compressor and length board. There were also small projects such as POP cutter, power supply for the CCBRT hospital. We were given a chance to choose our partners and the project of our choice to work on from the list of our needs findings. And submitted our choices to the design studio manager.                                        A 3d printer we found at CCBRT hospital when we went…

Atlast it works. The final prototype and presentation

Every beginning must have an end…….and this week signified the end to all the work we have been conducting throughout our internship/IPT period, most especially the individual group projects.  As explained in the previous week, we were assigned to design a bubble CPAP machine prototype.  Thus this week was all about implementation and modification of the prototype and also documentation of how the design was implemented. Implementation….. This part involved the following activities: Primary and secondary research Searching for equipment Bill of materials Purchasing equipment Building and testing of our circuit Fabrication of housing Fitting air and electrical circuit into housing Afterwards, followed the testing and implementation part, whereas we were able to test the prototype to see if it…

Digging deeper…

Digging deeper… At the end of last week most of the final projects and small projects were assigned to the intended student. And each one of us was required to start working on them immediately. By digging a little deeper and collect more information about the project (diverging) and then choosing from the list of information the most common ones (converging) to get close towards the solution. My partner and I were selected to do a bubble CPAP (continuous positive airway pressure) machine.   A bubble CPAP machine is a machine used to help a person with respiratory distress syndrome (RDS). It increases air pressure in your throat so that your airway doesn’t collapse when you breathe in. In this context we…

Needs finding: following the learning and practising of the Human-Centered Design approach.

For any possible solution to work appropriately, the designers of the solution have to understand the basis of the problem. It is termed as “Empathy”. Empathy: the action of understanding, being aware of, being sensitive to, and vicariously experiencing the feelings, thoughts, and experience of another of either the past or present without having the feelings, thoughts, and experience fully communicated in an objectively explicit manner.[1] This is therefore the first and foremost essential step when it comes to Human-Centred Design. This is where one gets the inspiration to pursue a solution for the challenge at hand.  This week we had time to do this exercise partly through research tools such as interviews and observations. We visited both Muhimbili National…

Using 3D printing to help in the fight against COVID-19 in Tanzania

‘Changamoto huleta Maarifa’ a Swahili proverb meaning ‘Neccesity is the mother of all inventions’.Perhaps the above quoted proverb is more relevant now than ever before in human history, as the world grapples with the appalling effects of the Novel Corona virus invasion. Apparently, the African continent is no exception in this, see updates: https://africacdc.org/covid-19/.  Even though infection rates may seem trivial for a continent of 1.2 Billion people and a country of approximately 56 million people, truth is- you can never underestimate the aggressive nature of a deadly contagion such as COVID-19. Undeniably, the COVID onslaught has been the biggest test to development practioners and actors across many continents.  In Tanzania, it offers yet again a realization that we probably need to…

DIT Design Studio: Innovation for COVID-19 Preparedness in Tanzania

By Julia Jenjezwa and John Msumba, PhD Tanzania is home to over 60 million people. Its largest city, Dar es Salaam, is home to five million people—a densely populated and vibrant port city. Located within this city, inside one of its many universities, is our country’s premier invention education design studio—the Dar es Salaam Institute of Technology (DIT) Design Studio—a space dedicated to student innovation that has become a hub for COVID-19 preparedness and response within our communities. I am Julia Jenjezwa, and it is my job to oversee the work of the DIT Design Studio. I work with my colleague and co-blogger, Dr. John Msumba, DIT Lecturer and Head of the Industrial Liaison and Career Guidance Department, to guide...
