Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing E-voucher issuance systems are limited in application scope, only supporting specific products, regions, payment modes, and order amounts, lacking flexibility in issuing or using E-vouchers for specific commodity configurations or types.
Innovation Solution
A method utilizing a tree structure of matching conditions with AND-OR relationships to process commodity information, allowing for fine-granularity matching and flexible formulation of matching conditions, enabling more precise and adaptable E-voucher issuance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tree structure of matching conditions with AND-OR relationships is used, then the adaptability and precision of E-voucher matching is improved, but the device complexity increases
Solution Approach 1:
The matching condition is segmented into a tree structure where non-leaf nodes represent AND-OR relationships and leaf nodes represent specific commodity configurations. This segmentation allows complex matching conditions to be broken down into manageable components, improving adaptability while maintaining structured organization.
Solution Approach 2:
The patent introduces a hierarchical dimension to the matching condition structure by using a tree format with multiple levels. This dimensional change from flat to hierarchical structure enables more sophisticated matching capabilities without proportionally increasing operational complexity.
2Measurement precision
If fine-granularity matching conditions are formulated, then the measurement precision and matching accuracy are improved, but the device complexity increases
Solution Approach 1:
Fine-granularity matching conditions are achieved by segmenting the tree structure into leaf nodes that represent specific commodity configurations. Each leaf node can define precise matching criteria for individual attributes, enabling high measurement precision while the hierarchical structure manages the complexity of formulation.
3Adaptability or versatility
If existing E-voucher systems are extended to support more commodity types and configurations, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The tree structure matching condition system provides universality by enabling a single framework to handle multiple commodity types and configurations through standardized AND-OR relationship nodes. This multi-functional approach extends E-voucher applicability without requiring separate handling mechanisms for different product categories.
Solution Approach 2:
The system introduces dynamics by allowing flexible configuration of matching conditions through the tree structure. The AND-OR relationships can be dynamically adjusted to adapt to different commodity types and configurations, enabling the system to evolve with business needs without proportional increases in structural complexity.

AI summary
A method for processing commodity information includes: obtaining commodity information of a commodity, in which the commodity information includes a target commodity configuration and a configuration value; obtaining a composite structure of matching conditions associated with the commodity, in which the composite structure is a tree structure of matching conditions with respect to commodity configurations, non-leaf nodes of the tree structure are in an AND-OR relationship, leaf nodes of the tree structure store Boolean expressions, each Boolean expression includes a commodity configuration, a matching value and a matching operator; obtaining a target expression having an AND-OR relationship by traversing the matching conditions in the composite structure; and obtaining a matching result by performing a matching process based on the target expression, the target commodity configuration and the configuration value of the commodity.
