AGV Spindle Reel Handoff: Deflection vs. Alignment
Of the 2.42 mm handoff error in EP4119475B1, spindle deflection is only 0.065 mm; vehicle locating and coupling lead-in dominate.
Two-Row Gripper on a Formation Jig: Force Balance
In KR101076412B1 a 0.5° tilt drops the weak row to a 1.23 contact margin, so 0.05 mm closed-position parallelism is the key control.
Reel-Core AGV Shaft: Deflection During Transfer
The US12209003B2 reel-core AGV shaft has a 13.1 strength margin, but a 0.257 mm tip rebound during transfer causes docking interference.
Formation Tray Pressing: The Side-Wall Reaction Path
In KR102088762B1 the 0.32 mm stack tolerance is 20 times the 0.016 mm wall deflection, so D = T must be held by the spring adjuster.
