It’s no secret that taking this class has made me look at the design and think of the design of everything around me, including things I used daily and had never thought about. One of these things is a door holder. A door holder can be so simple, and yet so efficient, and the fact that it doesn’t have to be heavy anymore is very intriguing. For this reason, I decided to analyze Harvard’s door holder and think about what made it so efficient. I arrived to three conclusions: shape, material and texture. First of all, the triangular shape of a door holder is genius and extremely efficient because it uses the space underneath the door and the fact that the door wants to close as an advantage. I love how well-thought it was because if it had been a different shape it wouldn’t have been nearly as efficient as it now is. The fact that the door holder uses rubber is also extremely intelligent because it really sticks to the door instead of pushing it back with it, and it also doesn’t have any risk of damage to the door. Lastly, the surface’s texture is extremely important so that it doesn’t slide through the surface, but really gets stuck. It’s amazing how something so simple can be so well-designed and effective to what it proposes to do!
