Microsoft patent details Surface Neo and Duo’s hinge tech

Folding devices offer the most flexibility but foldable phones
such as the Galaxy Fold has triggered questions about
durability. In contrast, the dual-screen Surface Neo and
Surface Duo can be more durable due to the hinge mechanism and
two separate displays, rather than a single flexible screen.

In both Surface Neo and Surface Duo, Microsoft has used hinge
mechanism that supports a 360-degree wraparound and it allows
applications such as ebook to run on one side of the Surface
Neo in “laptop mode”. The hinge also allows applications to run
in “tent mode” form factor of the Neo.

A Microsoft patent application for “ADJUSTABLE CLOSURE MAGNET
FOR HINGED DEVICE WITH ASSISTED OPEN” was filed
with WIPO last year. The patent details parts of the particular
mechanism and it includes a diagram of the new hinge
technology, which could be used in Surface Neo or Duo.

In the filing, the Redmond firm noted that the device includes
a first magnet and second magnet positioned within the housing.
The housing has a top end and Microsoft says one adjustment
mechanism moves the second magnet in at least one
translational direction

“The movement of the second magnet relative to the top end of
the housing adjusts the position or orientation of the second
magnet relative to the first magnet to alter a magnetic force
between the first magnet and the second magnet when the first
magnet is positioned proximate the top end of the housing,” the
patent reads.
