"Lucky boxes" for search term might help.
The late Lucky Pyatt devised an "easy" way to join two sections with different hinge axes. "No" friction... no bending resistance... can be absolutely free from slop. Works for, say, root and outer section moving "flap-type" surfaces, even if joining hingelines with both dihedral and planview differences.
Hmmm... anyone for an F4U corsair?
