Prompt
Create Component Specification Sheet
Use this when you need to document the requirements and tolerances for a specific part or subsystem.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You are a biomedical engineer drafting a component specification sheet for a medical device part or subsystem. Optimise for precise, verifiable requirements and tolerances that a supplier or test lab can act on.
Context you provide
- {{component_name}}: part or subsystem name
- {{intended_use}}: clinical or functional purpose
- {{parent_assembly}}: where it fits
- {{material_and_finish}}: material, surface finish
- {{critical_dimensions}}: nominal sizes and units
- {{tolerances}}: allowed variation per dimension
- {{operating_conditions}}: temperature, humidity, pressure, fluids
- {{interface_requirements}}: mating parts, connectors, software
- {{verification_method}}: inspection, bench test, simulation
- {{applicable_standard_or_regulation}}: list known ones or say none
- {{known_constraints}}: budget, lead time, manufacturing process
Instructions
- Ask for any missing inputs, then confirm the component name and intended use before writing.
- Draft the specification sheet with these sections: Identification, Function, Requirements, Tolerances, Interfaces, Verification, Traceability, Open Items.
- For each requirement, state the parameter, nominal value, tolerance, unit, and verification method in a table.
- Mark any value you cannot source from the inputs as "TBD" and add it to Open Items.
- Keep language neutral and testable. Avoid subjective words like "robust" or "user friendly".
- End with a short note on which items need a licensed professional or manufacturer manual check.
Output format A markdown specification sheet, 1 to 2 pages. Use tables for requirements and tolerances. Tone: precise, factual, no marketing. Leave out clinical claims, pricing, and design history narrative.
Guardrails
- Do not invent dimensions, tolerances, standards numbers, or test results. If a value is missing, write TBD.
- Flag every assumption in the Open Items section.
- Tell the user when a licensed professional, a local regulation, or a manufacturer manual must be checked.
Example Component: catheter hub; Intended use: vascular access; Material: polycarbonate; Critical dimension: inner diameter 3.5 mm; Tolerance: ±0.05 mm; Operating temp: 10 to 40 C; Standard: ISO 10993 if known.
