Apple Will Might Find Solution for Fraying Lighting Cables by Patent App

Apple has filed a patent application that could so easily avoid the fraying of its lightning cables. The patent is for a cable that could solve this issue with variable stiffness. Apple’s lightning cables have a reputation for easy fraying, but this patent may have found a workaround for the company. Ideas for a cable that won’t fray easily were suggested by the Cupertino-company. It speaks of a cable with ‘variable stiffness’ in the patent application and acknowledges that it is well known that bending the cable near the termination point where it reaches the phone could cause excessive strain on wire connections, which could lead to cable failure.

On August 3, 2019, Apple filed a patent application dated February 4, 2021. Apple Insider first spotted it.

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.
