I’ve found the source of the design (I think).

Following up on my post explaining the problems with the device, I pour through the Wookieepedia for some reasoning for how the current design could possibly work. I found some answers.

Today we received what we’ve been begging for months, a teaser for J.J. Abrams' upcoming Star Wars film, Episode VII - The Force Awakens... and a new lightsaber design.
