Grocery Cart Loops
Not many people realize that the loops which are part of the frame of the fold-out section can help protect the items you put in the cart. Vulnerable items can be hung on the loop to prevent them from getting squished by other items. This is definitely a great example of good design!
Lined Paper Margins
Why are there margins on notebook paper and why are the margins different depending on the grade the student is in? The second question can be addressed by another question – didn’t you know that the older you become, the more difficult things get? As for the first question, rat infestations were common and rats used to chew on any paper they found! Rodents could eat the edges, but because of the margins in place, they could not get to the important bits.
