Apple’s most recent U.S. patent shows further evidence of Apple’s interest in wearable devices. The patent, submitted on Tuesday, is for a new Apple product, tentatively named either the “iWatch” or “iTime.” This device would be a “Wrist-worn electronic device and methods therefor” and describes a range of possible configurations for wearable hardware. In one variant, the device is integrated with a wristband that includes electronic circuitry. In another, the device is a removable module that connects to an electronic wristband.

The operative word is “wristband,” which appears to be the base of the device and the focus of the patent. It appears that Apple will be creating a series of wearable devices that will have a wide variety of functions, as yet unidentified. In one variant, the modular electronics are integrated with a wristband that includes electronic circuitry. In another, there is a removable module that connects to an electronic wristband.

A modular approach creates possibilities for its wristband that are both thin and designed for optimal functionality. Rather than face the difficulty of designing an “all-in-one” device that tries to be “all things to all users,” a modular approach would also encourage the sale of multiple devices — and swapping devices in one’s wristband would be an easier way to manage battery life. The wristband could then serve as a power supply and communication hub for routing messages, alerts, and notifications to linked devices, or even iCloud.

All of this indicates that Apple is not interested in making a mere smartwatch along the lines of currently available products by rival companies. It also points to Apple’s continued pursuit of form over function. The patent tells where the device will be secured for users, while not focusing on what the device will do. The possibility exists of several removable and customizable hardware modules that can be fit to a specific need for each user.

Apple is expected to introduce a wearable device this fall.
