Engineering design personal statement example

Why do you want to study this course or subject?

The thing that draws me to engineering design is the gap between a drawing and an object that actually works. I noticed it properly while making a folding music stand for my Design and Technology coursework. On paper the hinge arrangement was neat; in the workshop the pivot loosened after about twenty cycles because I had ignored how the load path changed once the stand was leaned on rather than simply stood up. Redrawing it taught me more than the original design did, and I liked that the correction came from the material rather than from a mark scheme. Engineering design appeals to me because it sits between physics and manufacture. I enjoy the analytical side, particularly statics and the way a free body diagram makes a vague worry about strength into a number I can check. But I am equally interested in why products fail for human reasons: parts that are strong enough yet impossible to assemble in the right order, or fastenings that invite the user to do the wrong thing. My Saturday job has made that side vivid, since I spend part of every shift listening to why something has come back. I want a degree that keeps both halves together rather than asking me to choose between calculation and making. I am looking forward to structured teaching in materials, mechanics and manufacturing processes, and to design projects where a team has to justify decisions to someone other than themselves. In the longer term I am interested in product and mechanism design, possibly in transport or outdoor equipment, where weight, cost and durability pull against each other. I know my current skills are those of a beginner working with school workshop equipment, and that is exactly why I want to study the subject properly.

How have your qualifications and studies helped you to prepare?

My A levels are Maths, Physics and Design and Technology (Product Design), which I chose deliberately so that the analysis and the making would reinforce each other. In Maths I have found calculus the most useful area so far, especially differentiation applied to rates and maxima, because it gives me a way of thinking about optimising a shape rather than guessing at it. Mechanics in Physics has been the closest thing to the degree: moments, equilibrium, friction and stress and strain all appeared again in my coursework, and I now sketch a load case before I sketch a product. Electricity has been harder for me and I have had to work through past paper questions steadily to make it secure, which has been a lesson in persistence rather than talent. Design and Technology has taught me the parts of engineering that are not equations. I have learned to produce dimensioned orthographic drawings with tolerances, to use Fusion 360 for parametric modelling, and to be honest in an evaluation about what did not work. I have also learned basic workshop skills: lathe turning, brazing, and how much finishing time a design decision can cost. For my Extended Project Qualification I wrote about the trade-offs between aluminium and steel in bicycle frame manufacture, covering fatigue behaviour, weldability and repairability. Researching it pushed me into reading beyond textbooks, including material property tables and manufacturers' technical notes, and I had to learn to be careful about claims made in marketing material. Alongside this I have read Structures: Or Why Things Don't Fall Down by J. E. Gordon, which changed how I think about stress concentrations and cracks, and J. E. Gordon's discussion of why designers should worry about corners still comes to mind when I fillet an edge in CAD.

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

My main independent project came from a nuisance: my bike pannier hook rattled loose on rough lanes. Over about four months I designed a replacement clamp, modelling it in Fusion 360 and printing prototypes on the college 3D printer during lunchtimes. The first version split at the layer lines because I had printed it with the load across the layers, which taught me something about anisotropy that I had only read about. The fourth version, reoriented and with a thicker web, survived a term of commuting. I kept a logbook with sketches, print settings and rough load estimates, and I can explain clearly which decisions were reasoned and which were trial and error. I work Saturdays on the returns and customer service desk of a hardware and garden centre. It involves inspecting returned goods, deciding whether a fault is manufacturing or misuse, and writing short notes for the supplier. Taking apart failed strimmers and wheelbarrows has shown me how cost engineering decisions look after two seasons of use, and dealing with frustrated customers has improved my ability to stay calm and ask useful questions. I also manage my own rota and cover for colleagues, which has made me reliable about time. At college I help run the Duke of Edinburgh equipment store, checking tents and stoves back in, repairing pole sleeves and keeping the inventory spreadsheet accurate. It is unglamorous, but it has made me methodical and taught me that maintenance is part of design. I play tenor horn in a local brass band, where rehearsing a part until it fits with everyone else's has given me patience and a tolerance for repetition. Together these things have given me drawing skills, workshop confidence, an eye for how products fail, and the habit of finishing what I start.
