Dell seeks to Patent a unique Wireless Charging Clip for Future Notebooks that borrows from a general Apple Patent Concept
Apple has been working on the concept of integrating inductive charging into future devices like a MacBook and iPad since 2014. According to Apple’s patents, users will be able to rest their accessories in the palm rest area of MacBook for recharging. We covered a few of Apple’s patents here: 01, 02 and 03. One of the key Apple patent figures is presented as our cover graphic above.
In now appears that Dell wants to bring this concept to market. While it doesn’t want to challenge Apple’s patented approach, they’ve been working on a workaround approach using a detachable wireless charging clip for future notebooks.
One of Dell’s latest patents covers a system wherein a wireless charging clip attaches to a portion of a notebook. The wireless charging clip comprises a charging coil, a ferrite sheet positioned below the first surface, one or more mating elements to be coupled to respective mating elements of the notebook when the wireless charging clip is installed. The charging circuitry is configured to supply inductive power to charge an auxiliary device when the auxiliary device is placed on top of the first surface, such as a smartphone or earbuds.
In any of the disclosed embodiments, the one or more mating elements may include one or more magnets that, when magnetically coupled to respective magnets on the information handling system (notebook), cause the wireless charging clip to be installed on the notebook in a predetermined position.
he wireless charging market is expanding quickly. For example, computer accessories, cellular phones, smart phones, phone accessories such as wireless headphones and earphones, and other consumer electronic devices are increasingly powered in this fashion. Companion battery chargers for these devices extend their usefulness. However, large battery chargers, which typically have a higher capacity to supply power, may not be well suited for use with compact and/or ultra-thin accessory devices. Users often keep their smart phones turned on and nearby when working on their computers. Therefore, it may be desirable to be able to charge their smart phones using a charger that does not force integration into the computer itself, which could be costly, and does not interfere with the user's workflow.

It would be disappointing, to say the least, should Dell or any other OEM beat Apple to market with this concept, being that Apple has been working on this for the past eight years.
