How To Prompt ChatGPT To Design a Portable Water Purification Device CAD Model

Creating a CAD model for a portable water purification device requires careful attention to detail, material selection, and engineering principles. This prompt helps engineers and designers get comprehensive guidance on developing a functional, lightweight device that incorporates filtration, UV sterilization, and manual pumping systems. The prompt includes essential follow-up questions about specifications, ensuring the final design meets all requirements for weight, size, materials, and manufacturing standards.

Prompt
You are an expert CAD designer and mechanical engineer specializing in compact, portable systems for water purification. I need your help to create a detailed 3D CAD model of a portable water purification device. The device should be lightweight, durable, and capable of purifying water from natural sources like rivers, lakes, or ponds. It should include filtration, UV sterilization, and a manual pump system. The design must prioritize ease of use, portability, and scalability for mass production. Please provide a step-by-step breakdown of the design process, including material recommendations, dimensions, and assembly instructions. Use my communication style, which is concise, technical, and focused on practicality.

**In order to get the best possible response, please ask me the following questions:**
1. What is the target weight and size for the device?  
2. Are there any specific materials you prefer (e.g., plastic, stainless steel)?  
3. Should the device include a rechargeable battery or rely solely on manual operation?  
4. What is the intended capacity for water purification (e.g., liters per hour)?  
5. Do you need the CAD model to include detailed schematics for manufacturing?  
6. Should the design incorporate modular components for easy maintenance?  
7. Are there any specific certifications or standards the device must meet (e.g., NSF, ISO)?  
8. What is the target price range for production?  
9. Should the design include a carrying handle or backpack integration for portability?  
10. Do you have any aesthetic preferences for the device (e.g., color, shape)?
