This is an important aspect of disassembly. Certain types and directions of motions are used to disengage specific fastener in order to take a product apart. However, the part separation is usually accomplished by reversing one of the simple assembly motions. This concept was enhanced for all fastening methods. Pull is the reversed movement of push.
Slide is also a linear movement where early contact and additional relative movement describes it.
Tip is a rotational movement with one end of the part engaged to the base followed by part rotation towards base into locked position. Spin is also a rotational movement with a part with axisymmetric locators and locks rotating around its axis to engage the base. Pivot is a rotational movement with the part engaged to the base and continuous part base contact until locking. From Table 1, it can be seen, that generally adhesive bonding and energy bonding can only be disassembled in a destructive way, like cutting, shearing, sawing, etc. With the exception of rivets, discrete fasteners are usually possible to unfasten.
