Strap adjustment system for a cosmetic applicator configured for users with limited mobility

A method of adjusting a strap in a strap adjustment system for a cosmetic applicator configured for users with limited mobility, comprising:

• applying an unlocking force towards a housing cap disposed at an end of the cosmetic applicator, the housing cap and the end of the cosmetic applicator forming a chamber including a first opening and a second opening, the strap attached to the cosmetic applicator at a first end of the strap, a second end of the strap configured to pass through the first opening and the second opening, the strap adjustment system additionally including
• a locking feature disposed on a first side of the chamber and configured to (i) contact a first side of the strap, (ii) bias the strap in a first direction away from the first side of the chamber via a locking force, and (iii) force a second side of the strap to abut a first locking edge and a second locking edge of the chamber formed, the first locking edge formed as part of the first opening of the chamber and second locking edge formed as part of the second opening of the chamber, the locking force preventing translation of the strap through the chamber, and
• a roller wheel disposed on a second side of the chamber opposite the first side of the chamber, the roller wheel configured to (i) abut the second side of the strap when the unlocking force is applied in a second direction opposite the first direction to force the roller wheel into an engaged state, the unlocking force being sufficient to overcome the locking force applied by the locking feature and allow the strap to translate through the chamber, (ii) rotate in the engaged state to translate the strap through the chamber, and (iii) return to an unengaged state where the roller wheel does not provide sufficient unlocking force to overcome the locking force applied by the locking feature on the strap;
• and
• while applying the unlocking force towards the housing cap sufficient to overcome the locking force, applying a lateral force to rotate the roller wheel and translate the strap through the chamber.
