Workflow Orchestration for Rehabilitation Equipment Quality

Data Characteristics for This Category

Rehabilitation equipment quality documentation comes from various sources. These include design verification reports, production process control records, ex-factory inspection reports, user feedback, and adverse event records. Update frequency varies by document type. Design documents typically update with product iterations. Production and inspection records generate in real-time per batch.

Document structure often mixes structured tables and unstructured text. For example, design verification reports contain detailed test data tables alongside textual analysis of test results. Fields and units are highly specialized. For instance, "maximum output power" uses W, "noise level" uses dB, and "load capacity" uses kg. Specific testing standards and methods often accompany these. Documents may also include numerous charts, waveform data, and medical images.

Constraints Imposed by These Characteristics on "Workflow Orchestration"

Rehabilitation equipment quality documentation data characteristics impose specific workflow orchestration requirements. Data source diversity means workflows must integrate multiple file upload and parsing interfaces to handle various document formats.

Varying update frequencies demand flexible workflow trigger mechanisms. These must support real-time batch data processing and accommodate periodic design document updates. The mix of structured and unstructured data dictates that data extraction within the workflow combines table parsing with natural language processing techniques.

Specialized fields, units, and accompanying testing standards require semantic understanding models in the workflow to recognize these professional terms. Models must perform accurate unit conversions or validations to avoid misinterpretations. Additionally, the presence of charts and image data means workflows need multi-modal information processing capabilities. This includes OCR for extracting text from charts or initial classification of images.

Configuration Guidelines

Configuration Item	Suggested Value	Rationale
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	Rehabilitation equipment documents often include large test reports and image files, requiring support for larger uploads.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Parsing complex structured data and multi-page PDF documents can be time-consuming.
`maxContext`	`3000 Tokens`	Quality documents often contain detailed technical descriptions and multi-paragraph logic, requiring a larger context window for understanding.
`Chunk size`	`800–1200 characters`	Ensures each text segment contains sufficient information while avoiding excessive length that could lead to semantic drift.
`Recall count`	`Top 10 entries`	Quality document queries often require synthesizing multiple relevant segments for a complete answer, increasing recall quantity.
`Similarity threshold`	Calibrated by actual measurement	Balances recall precision and generalization ability based on the similarity distribution of rehabilitation equipment professional vocabulary.

Common Pitfalls

Failed to create post presigned url during file upload. This indicates incorrect storage backend configuration or insufficient permissions, preventing the generation of upload credentials.
Some table data is not correctly extracted after workflow execution. Key numeric fields appear empty or have incorrect formats. This happens when table structures are complex or contain merged cells, causing the default parser to fail.
Inaccurate query results for a specific device failure mode. This occurs due to poor knowledge base segmentation strategies in the workflow, leading to fragmented information or missing context.

Validation Steps

Upload a rehabilitation equipment design verification report PDF with complex tables and multiple pages. Verify all key fields are correctly extracted and indexed.
Query a document containing various professional terms (e.g., IEC 60601-1 standard, IPX7 protection class). Confirm the system accurately understands and provides relevant explanations.
Simulate the entry and query process for a device adverse event report. Confirm the workflow links newly entered events with existing knowledge and correctly references them during queries.
Check workflow execution logs. Confirm all file processing steps (e.g., file upload, parsing, segmentation) complete within the preset PARSE_FILE_TIMEOUT_SECONDS and without significant errors.
