Expandable component

A method of expanding an expandable charging device comprising the steps of:

• transmitting, via a remote device, an activation signal to a microcontroller;
• activating, via the microcontroller, a driving member;
• driving, via the driving member, a ridge along a guide between a first position to a second positon, such that an outer boundary expands radially outwards with respect to a rotatable member;
• receiving a proximity signal, from a proximity sensor, said proximity signal being indicative of an outer boundary being in proximity to an object;
• and
• receiving a resistance signal, from a physical resistance sensor, the resistance signal indicative of the ridge reaching the second position;
• and
• deactivating, via the microcontroller, the driving member in response to one selected from the range of:
• the proximity signal meeting a proximity signal threshold;
• and
• the resistance signal reaching a resistance signal threshold such that the expandable charging device no longer expands.

A method of contracting an expandable charging device comprising the steps of:

• transmitting, via a remote device, a deactivation signal to a microcontroller;
• activating, via the microcontroller, a driving member;
• driving, via the driving member, a ridge along a guide between a second position to a first position, such that an outer boundary contracts radially inwards with respect to a rotatable member;
• receiving, from a physical resistance sensor, a resistance signal, the resistance signal indicative of the ridge reaching the first position;
• and
• deactivating, via the microcontroller, the driving member in response to the resistance signal meeting a resistance signal threshold.
