20## Detailed Explanations
21
22### Factory Method - Carrier Service Creation
23
24**Problem**: Need to create different carrier service objects without coupling to specific classes.
25
26**Solution**: Abstract factory interface with concrete implementations per carrier.
27
28**Code Location**: `src/features/shipment-creation/services/carrier-factory.ts`
29
30**Example**:
31\`\`\`typescript
32const factory = getCarrierFactory('FedEx');
33const calculator = factory.createRateCalculator();
34const label = factory.createLabelGenerator();
35\`\`\`
36
37**Benefits**:
38- Easy to add new carriers
39- Follows Open/Closed Principle
40- Type-safe factory selection
