ILLUSTRATIVE SCENARIO
Focus inspection planning after a product change
An engineering change affects specific characteristics and measurement methods. An assistant prepares a traceable change list for quality planning.

Document AI · Characteristic extraction · Semantic comparison
What does the AI actually do?
AI converts descriptions in old and new records into comparable fields and suggests matches to existing inspection steps, including differently worded characteristics.
How the solution works
- 01
Extract characteristics
A document model reads text, tables and scanned annotations where necessary. Nominal dimension, tolerance, unit and identifier are stored separately with source locations.
- 02
Compare revisions
Semantic similarity proposes matches; deterministic checks compare values, units and tolerance limits. Uncertain drawing relationships are routed for review.
- 03
Propose inspection links
The assistant maps changes to CAQ inspection positions and explains the match. New or ambiguous characteristics remain explicit decisions.
What value can it deliver?
Less copying and manual comparison, with potentially more complete change detection. The benefit is a better-prepared inspection-plan revision rather than an assumed reduction in inspection scope.
A concrete example
Illustration: a tolerance changes from ±0.10 to ±0.05 mm. A numeric comparison flags the tighter limit, links the inspection position and requests a gauge assessment.
Technology, setup & operation
A pilot can use pretrained document models and a defined characteristic schema. OCR means optical character recognition. Engineering symbols, dimension relationships and poor scans need specific validation; structured CAD or PLM exports are preferable when available.
Illustrative solution design. The final architecture depends on data, systems and pilot evaluation.
Starting situation
A pump manufacturer changes a seal geometry. Inspection plans are currently compared manually with drawings and previous revisions. Planners need to determine which characteristics require new checks and which existing checks can remain.
How the workflow could look
Compare characteristics
The assistant extracts approved characteristic lists and drawing annotations. It flags changed tolerances, new features and uncertain matches.
Connect inspection context
It maps changes to inspection steps, gauges and previous measurements. Rule-based checks validate units and tolerance values.
Revise the plan
Quality planners receive justified proposals with source links. They determine measurement methods, inspection scope and approval.
