Seeing as how MCU Shuri is likely the mastermind behind T'Challa's goofy superhero suit and "stealth" jet, post Panther-themed inventions she might have created and how they horribly backfired.
For example:
Device: Morphotronic Sonic Arm Cannons
Function: A successor to the regular Sonic Arm Cannon that could shift between a weaponized state and a simple armored gauntlet form that would allow the wielder the use of their hands without taking off the device.
Status: Decommissioned. While the shifts between cannon and gloved states worked flawlessly on controlled lab molds of limbs, the unique irregularities inherent to the individual human hand were incompatible with the stringent mechanisms of the device, causing 1 out of every 6 test subjects to have their fingers completely shattered during the process.
