Reverse Engineering Candidates

This page is a supplemental addendum to the Webasto pilot dossier. It does not change the main recommendation, which remains an artifact-first battery and thermal change-pack review. It captures the useful part of the new reverse-engineering source without repeating or distorting the core Webasto story.

Critical Caveat

The reverse-engineering source itself makes an important point: it does not find public evidence that Webasto sells packaging machines. Its value is therefore narrower than the main Webasto dossier.

Use this addendum as:

• a generic packaging-machine component library for demo construction
• a backup set of CAD-rich parts if we need visually obvious diff and release-check examples
• internal guidance for future packaging-company demos

Do not use it to replace the core Webasto positioning around battery, thermal, JT, 3D PDF, and release-pack workflows.

What This Addendum Adds

• a shortlist of packaging-machine parts that are rich in revision logic
• strong candidates for visual diff and release-readiness storytelling
• a clear boundary between "useful demo assets" and "customer-evidence-backed Webasto fit"

Best Generic Packaging Candidates

Priority	Candidate part	Why it is useful	Best RapidDraft story
1	Lug-chain carton pocket side plate	Instant visual diff and a very easy jam or scuffing story.	pocket width, dowel, and datum changes
2	Vacuum manifold block for suction head	Feature-rich machined part with ports, grooves, and sealing surfaces.	threaded-port changes plus flatness and surface-finish checks
3	Product inserter pusher sled	Alignment-critical and mechanically dense without being hard to explain.	moved holes, added dowels, and thickness changes
4	Flap tucker arm	Strong closure-quality story and believable fatigue or backlash-driven revisions.	tolerance tightening, bushing addition, and arm-length changes
5	Hot-melt nozzle mounting bracket with heat shield	Good sheet-metal plus process-alignment example.	slot-range changes, bend-note gaps, and nozzle offset drift
6	Adjustable carton magazine side guide plate	Simple but realistic changeover part that accumulates revision noise.	slot-length changes, bend specs, and ambiguous adjustment intent

What This Means For The Webasto Wiki

The main Webasto pilot still stands on battery and thermal documentation, not packaging machinery. So the right use of this addendum is:

1. keep the public Webasto-facing wedge exactly where it already is
2. use these parts only if we need generic CAD assets for internal demos or cross-company packaging narratives
3. label them as representative packaging-machine components, not as Webasto product evidence

Best Use Cases For These Parts

These parts are most helpful when we need one of the following:

• a visually obvious revision-diff video
• a drawing-readiness check with rich dimensions, threads, datums, or bend notes
• a reusable packaging-machine asset bank for future pilots beyond Webasto

They are least helpful when the goal is to prove that RapidDraft understands Webasto's actual product stack. For that, the battery and thermal change-pack story remains stronger.

If We Reuse These Assets Later

If we end up using this part library in a customer-facing context, the safest framing is:

representative packaging-machine components used to demonstrate RapidDraft's revision and release-review workflow

That keeps the demo honest while still making the product visually concrete.
