Product design engineering personal statement example

Why do you want to study this course or subject?

The thing that pulled me towards product design engineering was noticing how often an object works perfectly on paper and badly in a hand. At the repair café I help at on Saturday mornings, the same faults come back: kettle lids whose hinges snap because the plastic is thin exactly where the leverage is greatest, vacuum cleaners held together by clips that cannot be undone without breaking them. Watching a volunteer explain to an owner that a £90 appliance was unrepairable because of a two-pence moulding decision made me want to understand who makes those decisions and on what grounds. I like that this subject refuses to separate the question of how something feels from the question of whether it will survive ten thousand cycles. In Physics I enjoy stress, moments and material behaviour; in Design and Technology I enjoy the slower business of drawing, modelling and finding out that my idea does not fit a human wrist. Product design engineering seems to be the discipline where those two habits of mind are expected to argue with each other, and where the argument is settled by testing rather than taste. I am particularly interested in design for disassembly and in the manufacturing constraints that shape everyday goods, because that is where good intentions usually fail. I want a course with workshop and CAD work, mechanics and materials taught properly, and projects that end in something I can put on a bench and break.

How have your qualifications and studies helped you to prepare?

My A-levels give me the foundations the course builds on. Mathematics has been the most useful: calculus and trigonometry appear constantly once you start calculating deflection or resolving forces, and mechanics modules gave me confidence with free-body diagrams. In Physics I found the materials and thermal topics most rewarding, and I now read data sheets with some idea of what Young's modulus and yield strength actually imply for a wall thickness. Design and Technology has taught me the practical discipline: iterative sketching, cardboard modelling, CAD in Fusion 360, and writing up test results honestly even when they contradict my first concept. For my coursework I designed a one-handed jar and bottle opener for people with limited grip, after interviewing two members of my extended family and a family friend with arthritis. I built four prototypes, printed three of them, and learned that my neat 3D-printed gripping ribs were far less effective than a cheap rubber sleeve. I redesigned around the sleeve and documented why. My EPQ looks at assistive devices more broadly and has pushed me into reading beyond the syllabus, including Donald Norman's The Design of Everyday Things, which changed how I write about affordances and error, and parts of Mike Ashby's material selection charts, which I found harder but genuinely useful for justifying choices. I also taught myself basic finite element analysis in Fusion, mainly to check whether my intuitions about where a part would fail were any good. Often they were not.

What else have you done to prepare outside of education, and why are these experiences useful?

In October I spent four days work-shadowing at a small kitchenware manufacturer near Redditch, arranged through my college. I was an observer and occasional pair of hands: I sat with a design engineer as she prepared drawings for a colander handle, watched tooling trials on an injection moulding machine, and helped a technician label and weigh sample parts for a batch check. Nobody let me near the press, quite rightly, but I was allowed to ask questions and I took eleven pages of notes. Two things stayed with me. First, how much of the engineer's day was spent negotiating with the toolmaker about draft angles and ejector pin marks, details never mentioned in my coursework. Second, how deliberately the company chose a metal insert over an all-plastic joint because returns data showed where handles failed. Design decisions there were answerable to evidence I had not known existed. Alongside this, the repair café has taught me steady diagnostic patience under a volunteer's supervision, and how to explain a fault to someone without being condescending. My Saturday job at a garden centre involves till work, stock rotation and helping customers choose plants, which has made me far better at listening before offering a solution. Outside work I restored a 1980s road bike, which meant learning bearing tolerances the slow way, and I sew, which is surprisingly close to pattern-based product design: flat shapes, seam allowances, and a three-dimensional result you cannot fully predict until it is made.
