Design Thinking

LEMELSON INTERNSHIP 2021 Blog #2 –  The first week of the internship was really a busy one, with a lot of skills to learn and a lot of challenges to work on. The second week however was really calm and more a week of reflections, discussions and sharing ideas amongst each other. We went through how one could come from a problem to a solution in a more efficient way. It was really astonishing to learn how understanding a problem well could make the journey from a problem to a solution a lot more productive. To better understand problems that were solved by technology, we looked at the attributes of an appropriate technology. It is important to make sure that…

STRONG WEEK

  Last week was a tough one because we did different activities such as studying the generation and failure of Roundabout Playpump appropriate technology in Africa, problem context and some lectures about empathy, synthesis, research methods and the double diamonds concept. After forming groups, my teammates and I were assigned to solve a pLS

Design is the intermediary between information and understanding… Neema Bryceson Kambo    21st August 2021 We started with a design thinking session where we were trying to understand how to internalize the problem through empathizing. The process required primary research (interview with the targeted end users) and later secondary research from different sources. During the study we were given a problem: “Why don’t people wash their hands at the DIT canteen?” in which we had to discuss some attributes of it. We analyzed the problem and came up with some attributes. Picture showing how we analyzed the hand washing problem  After the study we were divided into two groups: Team Amana and Team Selcom. I was in team Amana in…

SUMO BOT COMPETITION

SUMO BOT COMPETITION Fuad Abdallah, August 23, 2021. This week had a very exciting start with a sumo bot competition. The sumo bot competition is a sport in which two robots attempt to push each other out of a circle.  We were assigned to create a sumo bot for this competition. I started creating my sumo bot at home this past weekend by writing the program for the sumo bot and created a prototype. I tested it each time I updated my program. It was such a fun process because I even created my own ring at home to test it. I updated my program multiple times while testing it until I got what I intended, then I started designing…

The Human-Centered design

Problems happen every day in our societies and as human nature, we always try to find a way to solve them. But what differentiates a solution from a good solution? What differentiates a solution from the solution that is needed? As Engineers and problem solvers, we should never solve problems for our societies inside our labs, but we should reach out to society. We should reach out and build a strong empathy then conduct interviews to better understand those who we are building a solution for, thereafter we can use our skills to make an impactful solution. This approach is called the Human-Centered design approach.   The Human-Centered design approach helps us to create innovative new solutions rooted in people’s…

FIRST WEEK OF LEMELSON INTERNSHIP 2021

During this week we started by learning Computer Aided Design (CAD) using Fusion 360 Software. Fusion 360 is nice software to get started with CAD because it has a simple and friendly user interface and cloud storage capability for the projects which allows working on different computers. We started drawing basic shapes and specifying basic dimensions as normal Engineering drawings. After we had covered some basics we were given a task to draw 3D shapes and print them using a 3D printer. The figure below is the drawing which I was tasked to draw. The above object was used to certify us on our 3D printers skills. This certification required us to import an STL file from Fusion 360 then…

DESIGNING OF ULTRASONIC SENSOR AND INFRARED SENSOR (IR) 

DESIGNING OF ULTRASONIC SENSOR AND INFRARED SENSOR (IR)  Ultrasonic sensor An ultrasonic sensor is a sensor that measures the distance to an object using ultrasonic sound waves. It uses a transducer to send and receive ultrasonic pulses that relay back information about an object’s proximity.   How Ultrasonic Sensors Work Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing.  The transducer of the sensor acts as a microphone to receive and send the ultrasonic sound. Our ultrasonic sensors, like many others, use a single transducer to send a pulse and to receive the echo.  The sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse….

It’s all about learning

It’s all about learning!! The most interesting part of our lives everyday is learning,what I mean is never skip a day without learning a new thing. Try to add some new products to your brain shelves. To keep a long story short and precise I am going to give you a quick glance into what has happened and has been happening in the DIT Design Studio for the last two weeks (from the 2nd to 13th of AUGUST)  during the Lemelson Engineering Internship period. Well, the first lesson was about Design Thinking and then my question to you is have you ever designed anything in your life, career, job or anywhere? If yes then kudos! And if not this is…

A Busy week

  A Busy week Hindu Katowa, It has been a very busy and tough week with sleepless nights.We are running out of time.So we are supposed to work as much as we can so we can finish our final prototypes and prepare ourselves for the next week’s final projects presentations.So our team is working on the Automatic Chest Compressor.   But before we made a final prototype we made two prototypes which were piston and gear based chest compressors.And the processes were as follow: We started on making piston based prototype in which we 3D printed the piston and circulating rods Then we cut all remaining parts on a laser cutter. After that we assembled the parts and completed our first…

The struggle was real

The struggle was real  Kanyempwe, Juma B. Introduction With a lot of design work to do most of the projects were behind schedule so we never had a chance to write a blog post. We were trying to make the final project on time so we divided the tasks to finish on time. Mary and Joseph were designing and coding the circuit for the wall suction system while I had to go to kariakoo market  looking for the components we need for the project. We had two design concepts which were very promising for our project; mechanical system and sensor system.   Mechanical System is the system we design using a valve to block the negative pressure from the hospital…
