"This was a great book to introduce to my design students. My only concern is the usage of the term "triggers" as a positive prompt. This term is generally used negatively and was very difficult for our class to redefine as positive."

"From a usability perspective, I wonder if these are default to open with a spring. It would be very cumbersome to hold the nail, start it, then have to maneuver your fingers to release the clamped nail to finish driving it into the surface.In the end, is this just an extra tool for the novice that is fearful of getting their fingers smashed. If so, why wouldn't they just use any old pliers. A professional would never take the extra time to use this because it would slow them down so much.Seems like a design that no one asked for."

"This isn't the only design flaw. I've had to replace multiple parts on my Dyson vacuums either with cheap Chinese parts from Amazon or by 3D printing my own. They have not designed for durability nor for consumer repair."

"This is a cool concept but I'm confused as to how the geometry would work on a real vehicle. Most cars have very tight packaging on the front end and the interior turning wheel looks like it's intruding a lot into what would be the subframe area (engine, transmission, etc.)"

"Not sure if this originated in Norway, but these are a pretty common site in rural OH, NY, and PA."

"I understand the premise of finding a second life for discarded products, but the last two examples are products that can still be used in their first life. Pallet racks and water cubes are not ready to be repurposed if they still hold their basic function or can be repaired and reused in their original design. That's just creating more waste with the need to use more resources to have more new product in the stream."

"This is actually pretty old news. Toyota research found that animals like to eat wires and that soy is a red herring.Farmers have dealt with this for years. The real irony is that the reason many tractors are diesel, beyond the torque and efficiency compared with gas, is that mice and rats won't bother engines covered in a thin layer of diesel."

"Thanks for posting this! The SMU makerspace (the DIG) is doing pre-production today and will see how many we can make until we run out of supplies."

"There's a new version of the PRUSA that was redesigned by Design that Matters and is approved by NIH. It incorporates a brim on top to protect the wearer when they're looking down.As I've said in other postings online, being fast to production shouldn't necessarily be the goal. Most of the Apple face shields will have to be disposed of quickly, where other designs will be able to last multiple shifts after cleaning. Smaller clinics are preferring designs that can last a week or more, being sterilized each night."

"Screwtop cardboard liquid containers are a package design fail, not the user. It's almost impossible to get the last few drops of juice or almond milk out without opening it the "old" way."
