Footwear Size Evaluation System Using Development Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques fail to properly evaluate footwear size considering foot development, leading to discomfort due to improper sizing.
Innovation Solution
An information processing system that acquires user attribute information, determines evaluation timing and content based on age and sex, and provides recommendations for suitable footwear sizes using statistical foot development patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional footwear size evaluation techniques are used, then the evaluation process is simple, but the sizing accuracy does not account for foot development patterns
Solution Approach 1:
The system pre-acquires and stores foot development pattern data for different age groups and sexes before actual footwear selection. This preliminary preparation allows the evaluation system to quickly reference appropriate development patterns without complex real-time calculations, thereby improving sizing accuracy while maintaining system simplicity
Solution Approach 2:
The patent introduces foot development pattern data as an intermediary element between user attributes and footwear size evaluation. This intermediary layer enables the system to account for developmental stages without directly complexifying the evaluation logic, as the development patterns serve as pre-processed reference data that simplifies the actual sizing determination
2Measurement precision
If footwear size evaluation considers foot development patterns, then sizing accuracy improves, but the information processing complexity increases
Solution Approach 1:
The system segments foot development data by age groups and sexes into distinct categories. This segmentation allows the evaluation process to quickly identify and apply the appropriate development pattern segment without processing all possible data, thereby improving accuracy for the specific user group while keeping information processing manageable through targeted data retrieval
Solution Approach 2:
The patent changes the evaluation parameters from static size measurements to dynamic parameters that include age and sex-specific development patterns. By adjusting the evaluation criteria according to these parameters, the system achieves higher accuracy without proportionally increasing complexity, as the parameter changes guide selective data application rather than requiring comprehensive analysis of all data

AI summary
Evaluation of a footwear size in consideration of foot development is properly performed. An information processing apparatus includes an acquisition section, a determination section, and a provision section. The acquisition section acquires attribute information of a user who has purchased footwear in a size suitable for the foot development. The determination section determines information for evaluating the size of the purchased footwear based on an attribute of the user included in the attribute information acquired by the acquisition section. The provision section provides information for proposing footwear in a size suitable for the foot development based on an evaluation result based on the information determined by the determination section.
