When somebody asks me what I do as a Mechanical Engineer, I always have a hard time narrowing it down to just one thing.
I remember doing an interview at Apple, and the hiring manager explained to me what mechanical engineering is to them using a simple chair as an example. It’s amazing how much goes into something that seems so simple!
Designing a chair involves a multitude of considerations:
- Tolerance Stack-Up: Ensuring every part fits together perfectly, accounting for slight variations in manufacturing.
- Weight Capacity: Making sure the chair can support various weights without compromising its integrity.
- Safety: Ensuring the chair doesn't tip over easily and can withstand everyday use.
- Comfortability: Designing the chair to be ergonomic, providing adequate support for the user.
- Cost: Balancing material and manufacturing costs to create an affordable product without sacrificing quality.
- Material Selection: Choosing the right materials that provide the necessary strength, durability, and aesthetics. This involves understanding the mechanical properties and behavior of various materials under different conditions.
- Manufacturability: Designing the chair in a way that it can be easily and efficiently manufactured. This includes considering the capabilities and limitations of different manufacturing processes.
- Aesthetics: Ensuring the chair looks appealing and fits within the intended design style or brand identity.
- Sustainability: Selecting materials and processes that are environmentally friendly and considering the product’s lifecycle, from production to disposal.
- User Experience: Testing prototypes with real users to gather feedback and make necessary adjustments to improve the overall experience.
Every aspect of mechanical engineering requires meticulous planning, testing, and iteration. It’s a process that involves a deep understanding of materials, manufacturing techniques, and user needs. From initial sketches and CAD models to prototyping and final production, each step is critical to the success of the final product.
Mechanical engineering, in essence, is about being able to critically think and learn from every experience. No engineer knows everything, but through continuous learning and adaptation, we strive to make each product the best it can be.
Does anyone else find it difficult to explain their role in a single sentence?
