Abstract: The extraction of the structured mechatronic spec ification from unstructured PDF datasheets remains a critical bottleneck in hardware engineering workflows. Conventional NLP pipelines treat documents as linear token sequences, ig noring the inherently two-dimensional spatial organization of technical tables, This paper introduces A-RAG/SR-NLP, an Autonomic Retrial- Augmented Generation and Spatial-Relation NLParchitecture. The central innovation is the Spatial-Relational Constraint Engine (SRCE), which mode is the PDF canvas as a topographic terrain, computing Euclidean bounding-box distances and enforcing strict Y-axis orthogonality constraints. Candidate entities from a multi-model NER ensemble are val idated geometrically before ingestion into a Meta-Llama-3-8B Instruct RAG pipeline. Extensive experiments on a novel dataset of 250 mechatronic datasets demonstrate a 7-11% F1-score improvement and reduction of cross-row association errors from 12% to under 2% Compared to LayoutLMv3 and sequentail NER baselines. The system achives sub-second per-page latency, enabling industrial-scale Bill-of-Materials processing.
