Advantages of prototyping in the design cycle A prototype is the working model of the product or solution that is created before manufacturing the actual product. Prototyping is not only used in Engineering but also in marketing, education and the military. Prototyping is one of the essential processes during the design cycle. The diagram below shows the design process including the prototyping part. Figure 1. Engineering Design cycle The following are the advantages of prototyping in the design cycle: Prototyping gives an idea of the final product. It is difficult to visualize the look of the final product in the early stages of designing but when there is a prototype, we can get a basic look of the product…
Expansion 3DP – A STUDENT BUILT 3D PRINTER
^Our team and the completed Expansion 3D We are a group of 5 final year Bachelors students in the department of Computer Studies. We are genuinely interested in everything that deals or works with computers, ranging from networking, electronics and software development. During the first semester of the academic year 2020-2021 around mid-December, we decided to build a 3D printer as part of our coursework assessment for a core module named Robotics and intelligent systems. Having no prior experience in building a 3D printer nor a significant knowledge of its operation, we first had to understand how CNC (Computer Numerical Control) laser or plasma cutter worked as a means of building a fundamental background that could ease the understanding and...
Small and Amazing
SMALL AND FINAL PROJECT The last week was special for completing our small project and start dealing with final project after the visitation we made at Muhimbili National Hospital(MNH) and Comprehensive Community Based Rehabilitation of Tanzania (CCBRT Hospital). Where we conducted research and investigated different problems and challenges facing the Hospitals. As we observed different problems our task was to work on them and find solution based on either doing maintenance where needed and invading new appropriate technology. SMALL PROJECT From the starting day of our IPT sessions in DIT design studio, I acquired variety of knowledge in different parts like knowledge in Laser Cutting, 3D Printing, Arduino, Research knowledge and other Technological knowledge. Under Supervision and Training from…
Teamwork
Teamwork Bwere, Daniel E. In this internship, it is amazing how we work in teams. Unlike our classroom environment where most of the learning happens individually and sometimes in groups, the DIT Design Studio environment dwells on teamwork in order to get the job done. During the introduction when most of my colleagues were not familiar with one another, we had a close activity called “Think-Pair-Share”. This activity initially involved proposing a question to the team, then each member was given time to think independently. Thereafter members got into pairs and shared what each one thought of the answer to the question given. Another activity was the icebreaker event which was a rapid prototyping session. This session was a competition…
Testing and Implementation (Last Battle)
Testing and Implementation (Last Battle) – Thomas N. Shetui. Finally after all the learning and designing done in the course of eight (8) weeks in the DIT Design Studio, we came up with products that are expected to solve different problems that were found through needs findings sessions. Intensive primary and secondary research increased the depth of information and understanding. On my side, with my fellow engineering student Greg Luhambati, we came up with the Kenfix (KA-105) silicone sealant based subclavian access central line ultrasound training model seen in Fig. 1. Figure 1: KA-105 sealant based model Using the readily available plastic human torso, we filled it with the proposed material i.e. KA-105 sealant, after molding important vascular structures which…
Work, work and more work
Work, work and more work – Thomas N. Shetui At the end of last week, most final projects on needs findings were assigned to particular individuals. Each individual was required to start working on them and extend further from where the project halted. The task of collecting more information about the project was to broaden the options, enabling comprehensive approaches towards the solution to be an easy peasy process. With my fellow Industrial Practical Training member Greg Luhambati, we were chosen to work on a central line ultrasound training module. At first it required us to explore more on the currently used method to train health practitioner’s to perform a central lineprocedure prior to doing it to human subjects. Figure 1:…
The beginning of the end
The beginning of the end – Thomas N. Shetui After an intensive needs finding session at both Muhimbili National Hospital and CCBRT Tanzania, a significant amount of final projects emerged. Final projects such as bubble CPAP, wall suction system, UVGI, central line ultrasound training module, automatic CPR system and length board came from mostly two wards of Muhimbili National Hospital’s Pediatric Department while other small projects such as POP cutter blades were obtained from CCBRT Hospital particularly the Prosthetics and Orthotics Department. All the findings collected from both case study sites were gathered and compiled into titled projects as mentioned above. Though most final projects that needed extra attention were from Muhimbili National Hospital, there were some crucial insights…
Finally the end is here. FINAL PROJECTS
FINAL PROJECTS On this week we were assigned our final projects that were based on the problems we observed through our hospital visitation at Muhimbili National Hospital and CCBRT , our team was assigned to design a length board. A length board is an instrument that is used to measure the height of kids in hospitals so as to monitor their health progress. The existing length boards we observed at muhimbili national hospital had some problems that the users were facing . the existing length boards are completely made of wood so if they get in contact with water for a long time they will rot, also the head piece is very loose that sometime when the babies are measured…
COMPLETING INFRARED THERMOMETER PROJECT
COMPLETING INFRARED THERMOMETER PROJECT By: Arslan Dogar Infrared thermometer was the most challenging project assigned during the Industrial Practical Training period, it required us to code the Arduino program, testing the code by building actual circuit, soldering the circuit and diagnosis, 3d printing the housing design and finally fitting the circuit into the housing and testing. Initial Testing of the Circuit Some of these procedures proved to be very challenging and caused a lot of delay to the completion of the project, extending the time span to approximately 3 weeks. The main challenge that we faced during the project was the soldering and diagnosis of the soldered circuit, initially the delay had been caused by female headers not being available….
REVISIT TO MUHUMBILI NATIONAL HOSPITAL
REVISIT TO MUHUMBILI NATIONAL HOSPITAL By: Arslan Dogar The first visit to Muhimbili National Hospital was amied at needs findings for the hospital which resulted in alot of projects that we could work on. These projects included; the bubble CPAP (continuous positive air pressure) machine, wall sanction machine, the length board, automatic chest compressor and others. The project that we were assigned to complete was the Bubble CPAP machine for pediatric intensive care unit (PICU) at the hospital. There was an urgent need for the bubble CPAP machine in this unit of the hospital as it didn’t even operate a single CPAP machine. Basically Bubble CPAP is a non-invasive ventilation strategy for newborns with infant respiratory distress syndrome (IRDS). It…
