April 2020 Issue: Mechanism design using geometric contraints
Are we focusing enough on research? One of the things that’s most enjoyable about covering the design engineering space is seeing, on a continual basis, the amount of new technology being used in so many industries, from the component to the system level. But it’s important to realize that much of what feeds that pipeline…
March 2020 Issue: Space: key considerations in building optical assemblies
A snapshot of the additive industry It’s always interesting to examine who, how, and why engineers are using additive manufacturing (AM). Recently Stratasys Direct Manufacturing and SME Media conducted a survey on engineers and designers’ experiences with AM . The respondents either currently use or are considering using additive manufacturing. Of the nearly 700 respondents,…

Problem-based learning stands the test of time Engineering students at Stanford are well acquainted with the ME310 course. This year-long design course, now in its 53rd year, is built around problem-based learning. Students work in small teams, focusing on actual engineering problems presented by outside companies that partner with Stanford. The history and evolution of…
February 2020 Special Edition: Power Electronics Handbook
Why we don’t need energy efficiency standards for lighting HEADLINES WERE MADE RECENTLY when two national associations dropped a lawsuit attempting to squash light bulb efficiency standards in California. The California standards supposedly save Californians billions of dollars on their energy bills and avoid millions of tons of carbon- warming pollution. The suit was brought…
January 2020 Issue – Leadership in Engineering – Main Issue
Protecting yourself One of the more interesting talks I heard over the course of 2019 came at the recent Power Transmission Distributors Association’s Industry Summit. Frank Abagnale, whose early exploits as a con man and check forger were detailed in the 2002 film Catch Me If You Can, spoke about his life and his lessons…
December 2019 Special Edition: 2019 Fastener Handbook
The significance of small choices Years ago, during a high-school woodworking course, our instructor would walk through the shop, repeating: “It’s the nuts and bolts that count!” Students would laugh or roll their eyes. Interestingly, he rarely questioned students about the type of wood selected for a project (though I still have the chestnut bench…
December 2019 Issue: Using CFD to model aircraft fuel systems
What do your users think of your products? Any smart website designer or software company tests its products, not just for things like basic functionality, but for how the end user interacts with it. San Jose-based UserZoom recently published the results of a survey on user experience trends, and the results are fascinating. Survey respondents…
Special Edition: Women in Engineering
The growing number of women in leadership roles Women are less likely to be in leadership positions at bigger medical device companies, but the disparity is slowly shrinking. That’s the takeaway from this year’s Women in Medtech issue. Just 18% of executive roles at the top 100 publicly traded medical device are held by women,…

DHL’s U.S.-based Innovation Center showcases the latest in logistics technology, including robotics. TRI teaches…
Designing with sheet metal
Deciding to use—or simply consider—sheet metal for an application is the first step in a process. The process begins, of course, with function, which in turn dictates design. Choosing a material and gauge are critical steps that involve balancing factors like strength, weight, and cost. This is not a simple process, but it can be…
October 2019 Issue: Parametric modeling: What have we learned in 30 years?
Not a rosy outlook in industrial markets Scott Hazelton of IHS Markit gave an overview of the industrial markets for hydraulics at the recent NFPA International Economic Outlook Conference in Chicago. His outlook wasn’t a sunny one (“not a lot of roses,” he said), dovetailing with many of the other economic speakers at the conference…
September 2019 Issue: Compare roller-screw to ball-screw actuators
Celebrating more engineering creativity Last year, we launched the LEAP Awards, a competition to honor the best engineered components across the mechanical and electrical engineering spaces. Not sure what to expect with a first year’s awards program, we kept things rather simple … and were pleasantly surprised when we received well over 100 entries, making…
Injection Molding with Protolabs
DESIGNING PLASTIC PARTS for moldability has always been important for traditional injection molding processes, but it’s particularly beneficial during rapid injection molding to ensure speed and quality remain constant during manufacturing. This guide examines many of the important design considerations that are encountered during injection molding part design. Download the ebook from Protolabs to learn…
August 2019 Special Edition: Motion Systems Handbook
What ancient myths can teach us about today’s technology As our editorial team was preparing this year’s Motion Systems Handbook, covering the basics of motion technologies as well as their ongoing evolution, I began to wonder about the origins of the technology we cover.
