Apple Will Might Find Solution for Fraying Lighting Cables by Patent App
Apple intends to create a pressure relief sleeve made of a rigid material around the end region of the cable in the patent application. It is said that this rigid material will produce a localized increase in the cable’s bending resistance, which in turn will alleviate pressure on the wire connections. Apple also recommends further overall cable thickening. The patent application contains a pattern such as well
The patent signals that Apple is working with its charging cables to address a long-criticized problem. For now, however, this is just an idea and may or may not go into production. It is also worth mentioning that ‘Lightning Cables’ are not clearly stated anywhere in the patent, so this may be a wider design for Apple products.
‘A cable may include a cable core surrounded by an outer sleeve with a uniform thickness and a first longitudinal section with a first rigidity (e.g. a flexible cable), a second longitudinal section with a second rigidity (e.g. a rigid cable), and a third longitudinal section between the first and second longitudinal sections.’
The stiffness of the third longitudinal segment differs between the first stiffness and the second stiffness, where the second stiffness is greater than the first stiffness. “The second longitudinal section can provide the cable with strain relief,” Apple explained in the patent application.
