There was a cup on the door handle, but the door didn't open and the cup fell off. What happened?

There was a cup on the door handle, but the door didn't open and the cup fell off. There are several explanations:

1, the door handle does not completely fix the cup: the door handle may not firmly clamp the cup, resulting in the cup not being well supported on the door handle and eventually falling off.

2. Insufficient stability of the cup: the design or placement position of the cup itself is unstable, the center of gravity is high, or it is influenced by other external factors, which causes the cup to tilt and eventually fall.

3. Vibration or external force: When the door is not opened, there may be vibration or external force, such as the door being closed or slapped, earthquake, etc. These factors may cause the cup to fall.
