01 / Wearable systems research
Fit the shell
Distribute support through fitted structural surfaces.
The selected I4 direction uses thigh and shin shells, recessed joints, an under-pelvis bearing and structural shoes rather than a separate heavy powered frame.
02 / Wearable systems research
Carry the load
Keep the complete support path visible.
Body interfaces, joints and shoes must transmit load without introducing an incompatible fit or pressure point. Component masses remain partly allocated.
03 / Wearable systems research
Respect the motion
Separate supported standing from walking assistance.
Stance support and phase-dependent walking are distinct mechanical questions. The lightweight direction does not imply powered joint motion.
04 / Wearable systems research
Keep configurations distinct
Treat pressure and life support as additional systems.
Pressure garments, seals, breathing paths, sensing and thermal services have their own qualification needs. A ground-support outfit does not establish a usable pressure suit.
