E-commerce Size Customization for Tailored Apparel

The patent segments the size parameter system into two parts: common size parameters (S, M, L, XL) for standard production, and personalized size parameters (specific body measurements) for customization. This segmentation allows most products to be produced using standard fixed sizes while enabling personalized adjustments when needed, thus maintaining manufacturing simplicity for the majority of cases while improving fit accuracy for individual customers.

The patent changes the size parameter from fixed categorical values (S, M, L, XL) to dynamic personalized parameters based on actual body measurements. The system collects specific body dimension data and uses it to determine the most appropriate size, transforming the static size selection process into a dynamic parameter-based customization process that improves fit accuracy while maintaining efficient production through standardized parameter sets.

The patent implements a universal size parameter system that serves multiple functions: it handles both standard fixed-size orders and personalized customization orders through the same interface and processing logic. The system can process simple fixed-size selections and complex personalized measurements using a unified framework, reducing the need for separate systems and minimizing overall complexity while maintaining high fit accuracy.

The patent uses copying by storing and reusing standardized size parameter templates and body measurement data. Once a customer's body measurements are collected and processed, the resulting size parameters are stored and can be reused for future purchases, eliminating the need to重新collect and process the same data repeatedly. This copying mechanism reduces system complexity by avoiding redundant data collection and processing operations.
