A 3 view diagram of the craft with key system and overall dimensions shown.

An FEA modeling a very hard front off center impact. Something that might occur in the event of a system malfunction during capture.

A rendering showing the inside  structure and hardware placement. This version of the front doors was later dropped for a design that took of less forward area when when open. Minimizing this meant less chance of damage during capture.

Arresting cable system to tie down debris once inside the spacecraft. It was to utilize a spring loaded ratchet system that would spool in a cable routed around the inner perimeter. The yellow boxes were break sensors similar to those found in industrial automation settings. These would be used to detect when an object was in proper position for the cable to tighten down. 

Forward doors. These were split in to multiple sections to minimize complete door failure. If one door failed while open during capture, that door would be disabled and the other sections would still be able to close. Thus still providing some level of debris containment.

LIDAR Tilt Unit with the DragonEye. These were mounted in the front near the doors. The allowed the craft to automatically capture and map the debris.
