[0053] When a component is considered to be "on" another component, it can be directly on the other component or there can be intervening components present. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there can be intervening components present.

[0054] It can be understood that the term "vertical" is used to describe an ideal state between two components. In the actual production or use state, there can be an approximate or equal state between the two components. For example, in conjunction with numerical description, vertical can refer to the included angle between two straight lines in the range of 90°±10°, vertical can also refer to the dihedral angle between two planes in the range of 90°±10°, and vertical can also refer to the included angle between a straight line and a plane in the range of 90°±10°. The two components described as "vertical" can not be absolute straight lines, planes, but can be approximately straight lines or planes, and as a whole, the overall extension direction is a straight line or a plane, which can be considered as a "straight line" or a "plane".
