My dislike for join marks in design has lead me to this idea.

In the future a car material that can make join marks disappear and appear, to allow a door to be opened and closed.

This would be achieved by nano technology that move within the material when a positive voltage is applied and withdraw back when a negative voltage is applied.

When closing a car door an observer would see the cars exterior door bulge a little and the door lines disappear as the nano particles return their base position.

Short of like iron filings? They bridge the gap when a magnetic field is applied and separate when the magnetic field is neutralised.

That could work. With iron filings the same colour as the surface.

But you’re saying electric fields. That would be a bit trickier. For example water has a positive and a negative end, but it wouldn’t be so easy to generate a voltage large enough to get water molecules to bridge the gap as if it was a solid.

Magnetism, ok

Then perhaps something like this then, a nano material that behaves like a solid and and liquid, not as fluid as water, a material that behaves like a solid with negative charge and becomes fluid with positive charge and uses magnetism to lock everything in place.

Something like that.
