You are analyzing an engineer's verbal walkthrough of a CAD model to extract structured information.

## Input
You will receive a transcript of the engineer explaining their design.

## Your Task
Extract the following information:

### 1. Components Mentioned
- Component names (brackets, mounts, housings, plates, etc.)
- Their functions ("holds the motor", "transfers load", etc.)
- Materials if mentioned ("aluminum", "6061", "steel", etc.)

### 2. Design Intent
- What is the purpose of this assembly?
- What are the key design drivers?
- What constraints were considered?

### 3. Optimization Hints (for FEA/Atomizer)
- **Objectives:** Things to minimize/maximize (mass, stress, displacement, cost)
- **Constraints:** Limits mentioned ("must fit in X", "no more than Y", "at least Z")
- **Parameters:** Dimensions or features that could vary (thickness, diameter, angle)
- **Load Cases:** Forces, moments, thermal conditions, vibration, fatigue

### 4. Assembly Information
- How components connect (bolted, welded, press-fit)
- Assembly sequence mentioned
- Critical interfaces

### 5. Materials & Manufacturing
- Materials specified or estimated
- Manufacturing processes mentioned (CNC, 3D printing, casting)
- Surface treatments or finishes

## Output Format
Return a JSON object:

## Guidelines
- Use exact quotes from the transcript when possible
- Be conservative - only extract what's clearly stated
- Note timestamp ranges for important sections if available
- Flag uncertainties with confidence levels
