Finite Element Analysis: How to Use Hooke’s Law to Dial in Simple FEAs

Any professional mechanical engineer knows that Finite Element Analysis (FEA) is an essential tool used to analyze stress (deflection, FOS, and more) in a design based on different loading conditions. A huge part of conducting FEA centers around research. When you start the process, you don’t yet know what you don’t know. You need to […]

Practical Guide to Prototype Testing

Aesthetic design is in the eye of the beholder, but functional prototypes have a different standard—testing—and for most of us, exam day has never been something to which we look forward. However, test day doesn’t have to fill you with the fear you felt going into high school Calculus exams: By setting clear design expectations […]

4 Fundamental Objectives of Prototyping Hardware

When you set out to prototype a new hardware product design, it might seem like there are an overwhelming number of features to test and develop. You want your product to be the best it can be, but the path to get there from a great idea isn’t always clear. While prototyping hardware is a difficult and […]

Pre-Production Hardware Testing Methods

The pre-production phase of the hardware product development cycle encompasses the commonly mentioned EVT (Engineering Verification Test), DVT (Design Verification Test), and PVT (Production Verification Test) segments. There’s a common misconception that each segment denotes a pre-production build on a rudimentary assembly line, however the T in each of the “(X)VT”s stands for Test, signifying […]

Strategic Testing Methods for Early Stage Hardware Development

Good products are developed with an iterative process (James Dyson famously made 5127 failed prototypes before he delivered a working Cyclone bagless vacuum). But while an iterative process is the most successful hardware development strategy, prototyping hardware can be expensive and time-consuming. So to get the most value out of each prototype, you need to aggressively […]

Hardware Testing 101

Software and hardware engineers alike have heard some form of this advice: “Build lots of prototypes; iterate as fast as you can.” For those of us in the hardware industry, these prototypes can cost a lot of time and money. So while we should strive to iterate quickly, we must also get as much information […]
