So how many ways are there to emit a Shield / Force Field?

We know the grooves on the hull are the location of a Shield Grid Network and used for creating either a
Tight Form Fitting Shield Layer above the surface of the hull, I prefer to call it a "Skin Shield" for brevity.
or
A Ellipsoid Bubble Shield that we've seen commonly in TNG, DS9, VOY.

We know Shields can be shaped arbitrarily as flat panels, bubbles, columns, skin hugging fields, etc.

We know that Shields can be emitted from the Main Deflector Dish or a Seperate Antenna Panel like on DS9.

We know that the Navigational Deflector Dish emits a low powered Shield several km in front of the vessel traveling at warp that "Deflects" tiny particles away

What other ways are there to emit a "Shield Field" of some sort or do we need to invent another way?

If we accept the backstage doubletalk that shields are gravitons trapped in projected trenches of some sort, we probably shouldn't be thinking in terms of "ways" at all. Gravitons can apparently be "bled" to and from places easily enough, and projecting in Trek is a fine art as seen on holodecks. Creating a shield the shape of a wriggling pretzel at an arbitrary midair location is probably the very thing the holodeck does! Perhaps using the shield grid method in the TNG style applications, and projection antenna arrays in the VOY style facilities...

...But once you start projecting, you can also meta-project, projecting new hardware, so that your antenna projects a grid for you, or your grid projects an antenna for you. So pretty much anything with a bit of projecting ability can be turned into a shielding device, including a commbadge.
