Reflecting on our Design Study projects: First-year students share their experiences

 

Just before the end of term, our first-year undergraduate students completed their Design Study projects. Congratulations all!

The Design Study project concludes the Engineering Practice module for our first-year undergraduate students. Over six months, teams of twelve students collaborated on the hands-on project, presenting their final designs to company directors. This year’s task was to create a hardness testing machine that compresses and indents a powder and then uses camera analysis to calculate the powder’s hardness.

In the blog post below, three of our students discuss their projects and what they have learned from the experience.

The Design Study project was designed by Dr Eleonora D’Elia (module lead) and Dr Priya Saravanapavan (module co-lead) and is supported by our lab technicians, Ben Chan and Ivan Cespedes Fernandez.

Ellie Abel

What was your position in the team?

I was the Director of our company. My job involved identifying and integrating the company’s strengths, maximising efficiency, minimising confusion and ensuring a high-quality product. I ensured constant communication between subgroups, led the structural design by coming up with a vision for our machine, contributed to SolidWorks, addressed engineering and testing issues, and ensured tasks were completed on schedule. Whilst also overseeing the assembly process and integrating any necessary structural adaptations. This resulted in effective production and fluid project completion.

Can you tell us more about the project? 

Our design study project was to design a Vickers hardness testing machine that could compact, indent, and perform image analysis on a powdered sample. We worked collaboratively as a company to ideate, design, manufacture, reassess and enhance our system. As the project progressed, we began to learn each other’s unique strengths. We worked as a human assembly line of individuals to technically draw, manufacture, analyse, automate and refine our initial concept into a functional machine. As a company, we prioritised product marketability, which we associated with the machine’s efficiency, functionality, aesthetics, and robustness. As a result, our design was incredibly modular, allowing us to easily isolate components and carry out testing more efficiently.

What did you learn?

As an engineer, you often design a system to fulfil its primary function. Then, you consider any external/influencing factors that affect or could impact your system functionality before accounting for your selling point of “nice to haves”……but what you often neglect, and what we learnt to consider, is the method of processing. Is your design suitable for the method of processing you’ve selected? Is it feasible to use that method of processing? Is it cost and material-effective to use that method of processing? As a team, we learnt that behind every finished product there’s a story to be told. The true art of engineering is to identify, adapt, analyse and enhance all aspects of machine functioning.

What advice would you have for future students?

Start your automation Al component testing first and spend the rest of your time enhancing them. Your structure is purely casing and if your internal system doesn’t work, you don’t have a machine.

What was your position in the team?

My role during the project was Chief Engineer. I led the design stage and did the majority of the 3D modelling. When my workload was too great, I assigned team members tasks since teamwork was key, and making everyone feel included in the project was important.

Can you tell us more about the project? 

For this year’s design study project, our team put our heads together to design a hardness testing machine to test the hardness of powders. We needed to design a machine that first compacted the powder and then created an indent that could be used to analyse the hardness. As cost efficiency was our priority, we chose a design that used a rotational section in the middle to reduce costs. 

What did you learn?

I learnt that communication and organisation are extremely important when doing group work, especially in bigger groups such as this one. My 3D modelling skills have also improved, yet I think I still have room for improvement in the future.  

The highlight for me was when all the project materials arrived and we began assembling the machine. It was very satisfying to see what we had envisioned on a computer screen come to life. 

What advice would you have for future students?

Don’t feel discouraged during the project! Even if the task seems large at the beginning, working throughout the year and in smaller chunks can help you achieve something big. 

Matt Cooke

What was your position in the team?

I was the Director of my group, which was a very hands-on leadership role. I ensured that everyone contributed effectively and we met our deadlines.

 

Can you tell us more about the project? 

The design of our machine involved a single linear actuator which had two tools – the compressor and the indentor – rotated underneath it in turn to be pushed to the powder. The tools attached to the actuator use a smart magnetic catch system to ensure alignment every time. Its design was constantly refined and modified throughout the process, right up till the days before the presentation! We were proud of how well this design functioned, and we won the prize for innovation which made our work feel appreciated.

What did you learn?

During the project, I learnt a lot about leadership in a large team and how important a good communication chain is. It helps even the work distribution among members and ensures everyone is in the loop and knows details about the project.

In addition, we collectively learnt a lot more about 3D printing and laser cutting, and we relied on our computer-aided design knowledge from the autumn term. We also analysed suitable materials for each part of our project, and cost and availability played large roles in the final decision-making.

What advice would you have for future students? 

I recommend carefully choosing candidates for each role and playing to everyone’s strengths. Ultimately, good teamwork and communication are the foundations of a successful team, but it’s also important to have fun and enjoy the engineering experience.

MSc spotlight: Srikar Varanasi on his MSc journey and research project

 

Name: Srikar Varanasi

Position: MSc student studying Advanced Materials Science and Engineering. 

In this blog post, Srikar shares more about his journey in the Department of Materials at Imperial College London.

Why did you choose to study for an MSc in Advanced Materials Science and Engineering?

With a background in mechanical engineering, I spent years learning about mechanics, dynamics, and the intricacies of designing and analyzing mechanical systems. However, I was curious about what makes materials behave the way they do. What gives materials their strength? How are they made? What happens at the atomic level when materials interact? And how do you study them? This curiosity led me to materials science, a field that sits at the intersection of chemistry, physics, and engineering, providing answers to these questions and offering endless possibilities for innovation. When it came to choosing where to further my studies, Imperial stood out with its strong reputation in research and the opportunity to work with some of the brightest minds in the field, making it the perfect choice. 

What do you enjoy about studying at Imperial?

Living in London has been a childhood dream come true. The city is a melting pot of cultures, offering endless opportunities for exploration and entertainment. Whether it’s visiting world-renowned museums, exploring myriad parks and historic landmarks, or indulging in the vibrant food scene, there’s always something to do.

Moreover, being in London means being at the heart of a major global city which is a hub for many industries and, of course, research. The proximity has provided me with opportunities for networking and attending industry conferences and events. Another great aspect of studying at Imperial is its student diversity. I have met people from various parts of the world, each bringing their unique perspectives and experiences. This diversity enriches classroom discussions and group projects, making the learning experience more holistic. 

What have you enjoyed about the course?

The course has been both challenging and rewarding. I have chosen to study the ceramics modules and materials characterization exercise was a great learning experience. Having no prior experience in characterization techniques, the exercise helped me grasp how materials are studied at a fundamental level.

As a student from a different background, the course has given me enough time to catch up with my peers. Even though it is just one year long, it doesn’t feel rushed. The pacing has been well-balanced, allowing for deep dives into complex topics without feeling overwhelming. The course includes seminars and guest lectures from industry leaders and researchers, providing insights into the latest advancements and trends in materials science. These opportunities to learn from and network with professionals are invaluable. 

Can you tell us about your summer project?

This summer, I’m working on an exciting project related to composite materials, specifically focusing on Carbon Fibre Reinforced Polymers (CFRP) used in offshore pipelines. The aim of my research is to understand how these composite materials degrade when exposed to petroleum products, ultimately leading to failure.

CFRP is widely used in the oil and gas industry due to its high strength-to-weight ratio and excellent corrosion resistance. However, the harsh environmental conditions in offshore applications, combined with prolonged exposure to petroleum products, can lead to degradation over time.

My project involves simulating these conditions in the lab to study the degradation mechanisms at play. Through a series of experiments, I’m analysing how components of petroleum interact with the interface between the polymer matrix and carbon fibres, which is the most crucial part responsible for transferring the stress from the matrix to the fibres, thus giving them strength in the first place. This involves using advanced material characterization techniques such as in-situ SEM techniques to observe changes in the microstructure and mechanical properties of the composites. 

Why did you study this area and why is it important?

This research is crucial because it addresses a significant challenge in maintaining the integrity and safety of offshore pipelines. By improving our understanding of material degradation, we can help prevent pipeline failures, which can have severe environmental and economic consequences.

Prior to this, I worked on the structural integrity of aircraft structures using CFRP during my undergraduate project. This experience gave me a solid foundation in understanding the mechanical properties and advantages of CFRP in high-stress applications. It also sparked my interest in exploring how these materials perform in different environments, leading me to my current research on their degradation in offshore settings. 

What’s something others would be surprised to learn about you?

I’m an avid explorer and hiker. I have a deep love for adventure and discovering new places. I’m known for embarking on journeys where I’d happily walk 40,000 steps if it meant encountering something I’d never seen before. Whether it’s trekking through rugged mountains or exploring hidden trails, I find joy in immersing myself in nature and embracing the thrill of exploration.
