Abstract
A method is disclosed. The method may include providing a force-applying apparatus installed on a first body and disposed between the first body and a second body. The method may include receiving, through the force-applying apparatus, a first control instruction. The method may include generating a first acting force from the force-applying apparatus based on the first control instruction, the first acting force pushing the second body away from the first body. An apparatus and system are also disclosed.
Claims20
A method comprising:
- providing a force-applying apparatus installed on a projection lens;
- coupling, via a force, the projection lens and a projection base;
- receiving, through the force-applying apparatus, a first control instruction;
- and in response to receiving the first control instruction, generating a first acting force from the force-applying apparatus based on the first control instruction,
- wherein:
- the force-applying apparatus is disposed between the projection lens and the projection base,
- the projection lens and the projection base are coupled via the force, and
- the first acting force pushes the projection base away from the projection lens with an amount of force that decouples the projection lens and the projection base to completely disconnect the projection lens from the projection base allowing removal of the projection lens by a user.

An apparatus comprising:
- a control component configured to receive a first control instruction;
- and
- a force-generating component configured to generate a first acting force based on the first control instruction,
- wherein:
- the apparatus is arranged between a projection lens and a projection base,
- the projection lens and the projection base are coupled via a force,
- the force-generating component generates the first acting force in response to receiving the first control instruction, and
- the first acting force pushes the projection base away from the projection lens with an amount of force that decouples the projection lens and the projection base to completely disconnect the projection lens from the projection base allowing removal of the projection lens by a user.

A system comprising:
- a system body;
- and
- an electronic device comprising:
- a projection base coupled to the system body,
- a projection lens coupleable to the projection base via a force, and
- a force-applying apparatus installed on the projection lens,
- wherein:
- the force-applying apparatus is disposed between the projection lens and the projection base,
- the projection lens and the projection base are coupled via the force,
- the force-applying apparatus is configured to generate, in response to receiving a command signal, a first acting force on the projection base when the projection lens and the projection base are coupled via the force, and
- the first acting force includes an amount of force that decouples the projection lens and the projection base to completely disconnect the projection lens from the projection base allowing removal of the projection lens by a user.
