According to a report on Apple Insider, future Apple Watch bands could contain more electrical and data contacts, paving the way for the possibility to add replaceable power sources or add sensors outside the watch.
In a patent granted to Apple by the US Patent and Trademark Office for "Accessory Contacts," the company said in the report that a solution could be found in contacts embedded within the connector used to affix bands to the Apple Watch.
The report quoted the filing as saying the system would somewhat resemble the existing method of connectivity for Apple Watch bands, with a section that slides in from a side and is held in place using spring-loaded pins that pop into recesses within the Apple Watch body. A button can be pressed to pull the pin sections back, allowing the band connector to slide out.
