-Imagine installing a simple mechanism at the hook opening of the clothes hanger. When the bamboo pole is touched, it will open, and when it is hung, it will automatically bounce back and seal. When the fork touches the bottom of the hook, the mechanism will open and be convenient to take off.
2) Some buildings are equipped with garbage chute, which is very convenient for dumping garbage. The disadvantage is that when the door is opened, the smell pours into the house, and when you reach into the chute to dump the garbage, it is easy to get dirty by the garbage falling from it.
-Imagine changing the slot door into a drawer. When it is opened, the bottom is closed and can be filled with garbage. Push it, the bottom will open, and the garbage will fall. In this process, the tank is separated from the room, and there is little odor entering.
3) The mirror in the bathroom will be covered with water vapor and fog, which is inconvenient to use.
-Imagine installing a heating wire (low voltage) on the back of the mirror, so that the mirror will not fog after heating.
4) The image you see in the mirror is not true (upside down), which is easy to prove: try to put your right hand on your face, but the image you see is on your left hand.
It is not difficult to see your true image in the mirror, as long as you are on two walls in the concave corner of the wall.
Two rectangular lenses can be assembled vertically.
5) When walking the dog, the dog urinates in the street, which destroys the environmental sanitation and makes the owner quite embarrassed.

6) Urban psoriasis pollutes the environment and is difficult to remove.
-Imagine making an effective cleaning tool. It is suggested to use high-pressure steam, wire brush, detergent and high-pressure water jet, which should be a feasible method. If successful, you can apply for a patent, which is beneficial to both public and private.
