Thoughtless Act: Unused Doorknobs

• Thoughtless Act: Unused door handles

Pictures are taken from Etcheverry Hall, where mechanical engineering labs are. (They are all different doors although they look almost the same!)  It appears that people in this building tend to open the door by pulling the door edge instead of using the door knob/handle, especially when the door is already (slightly) open. When the door is slightly open, people don't have to turn the door handle to open the door, but just need to pull the door somehow. However, apparently the most intuitive location for pulling the door in this case is the edge of the door, not the door handle! It leaves finger marks on the door, which brings not so hygienic/aesthetic look. 

Perhaps this problem can be solved by replacing the current door handle with a new door handle, which can cover various heights. (Sketch is attached) This will make opening the door easy for everyone, from very tall people to very short people, and  even people who use wheelchair by giving them an optimal, intuitive location for the door handle.
