Reverse Engineering Candidates

This page is a supplemental addendum to the SOMIC pilot dossier. It does not change the core recommendation, which remains revision-before-release review. It adds the most useful concrete part candidates to build if we want a SOMIC-flavored demo dataset that feels native to their machines.

What This Addendum Adds

• a tighter shortlist of SOMIC-like parts instead of generic brackets
• a clearer mapping from SOMIC product language to believable CAD assets
• realistic failure injections for RapidDraft diff and release-readiness demos

Best Parts To Build First

Priority	Candidate part	Why it is strong for SOMIC	Best RapidDraft story
1	QuickChange locating adapter plate	QuickChange is central to SOMIC's public positioning, so a locating part makes the "no extra tweaking" promise mechanically visible.	revision diff plus release-hygiene checks on dowel holes, rev labels, and locating dimensions
2	Hot-melt glue nozzle mount bracket	Glue placement is high-consequence and easy to explain to both engineering and management.	geometry change plus missing flatness, hole-callout, or note mismatch
3	CORAS carrier product nest insert	CORAS is one of the most SOMIC-specific public differentiators, and product-matched nests naturally accumulate revisions.	pocket-size change, section-view drift, and material-note gaps
4	Folding die block	Folding and carton erection are core to the line, and die alignment changes feel critical immediately.	datum change not reflected in drawing and old assembly reference still carried forward
5	QFeed idler sprocket mount plate	Conveyor tension and guard integration are realistic revision drivers with very reviewable drawings.	slot-length changes, added guard holes, and incomplete interface notes
6	Lamella pusher head side plate	Lamella Chain gives us a second SOMIC-native handling mechanism beyond the main cartoner modules.	moved hole pattern, tolerance omissions, and assembly-reference drift

Geometry Snapshots

These snapshots are intentionally compact. The goal is to give the reader a mental picture of each part without forcing them back into the source .docx.

What This Clarifies Beyond The Existing Dossier

The existing SOMIC pages already establish the wedge: RapidDraft should help SOMIC understand what changed before release. The new source sharpens one practical question that the earlier dossier only implied: which parts should we actually model if we want the demo to feel like SOMIC rather than like a generic machine shop sample.

The strongest answer is to prefer mechanism-adjacent format parts over generic support hardware. The best candidates are the parts that sit at the boundary between modular machine architecture and customer-specific format changes:

• QuickChange locating and swap parts
• glue-positioning and sealing hardware
• CORAS carrier or nest geometry
• folding-tool interfaces
• conveyor and transfer components with adjustment logic

Realism Rules For The Demo Dataset

• Favor parts that a SOMIC engineer would plausibly swap, adjust, or re-release during a format change.
• Keep at least one part tied to QuickChange, one to product handling, and one to folding or gluing.
• Make the injected issue look like a real release mistake, not a random geometry error.

The most believable injected issues from this source are:

• revision table updated but title block not updated
• critical hole or datum moved but tolerance scheme not revised
• section view or detail view left stale after a pocket or profile change
• material, finish, or interface note missing after a real geometry revision

Recommended Build Order

If we only build three parts for the next SOMIC-facing demo pass, use this order:

1. QuickChange locating adapter plate
2. Hot-melt glue nozzle mount bracket
3. CORAS carrier product nest insert

That trio gives us one clean setup and locating story, one precision process story, and one unmistakably SOMIC-specific handling story.

What To Ask SOMIC For Next

This addendum also makes the external ask more concrete. The best follow-up request is no longer just "send a revision pair." It is:

1. one scrubbed format-part revision pair
2. one carrier or nest style drawing, even if redacted
3. one changeover or approval artifact that shows how they describe the change today

That would let the demo move from representative SOMIC-like parts to SOMIC-shaped evidence.
