Shoe Recommendation Device Using Foot Growth Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoe product information systems fail to provide suitable recommendations based on the foot shape of users, particularly distinguishing between adult and child foot shapes, leading to discomfort and poor fit due to inadequate consideration of foot shape changes with age.
Innovation Solution
A shoe product information providing device that predicts future foot size using statistical data and user information, determines whether foot growth has ended, and selects appropriate product information from child or adult categories for recommended shoe sizes, incorporating foot shape and size data to recommend suitable shoes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If shoe product information is provided based only on foot size without considering foot shape, then the selection process is simple, but the shoe fit and comfort are insufficient
Solution Approach 1:
The patent segments the product information into two distinct categories: child product information and adult product information. This segmentation allows the system to provide simple size-based recommendations while ensuring the correct foot shape type is targeted, resolving the contradiction between selection simplicity and fit accuracy.
Solution Approach 2:
The patent performs preliminary determination of foot shape type (child or adult) before providing product recommendations. By predicting future foot size and determining foot shape type in advance, the system prepares the appropriate product category, ensuring accurate fit recommendations without complicating the user's selection process.
2Loss of time
If shoes are selected without considering whether foot growth has ended, then the purchase process is quick, but the shoe may not fit properly as the foot grows
Solution Approach 1:
The patent performs preliminary prediction of future foot size and determination of foot growth status before providing product recommendations. This allows the system to account for ongoing foot growth and recommend appropriate shoe sizes and types in advance, ensuring proper fit without requiring multiple purchase decisions over time.
Solution Approach 2:
The system uses predicted future foot size as feedback to determine whether foot growth has ended, which then informs the product recommendation. This feedback mechanism allows the system to adapt recommendations to the user's growth stage, ensuring suitable shoe selection while maintaining a quick purchase process.
3Adaptability or versatility
If child product information is provided to users with adult foot shape or vice versa, then product availability increases, but shoe comfort and performance decrease
Solution Approach 1:
The patent segments product information into distinct child and adult categories based on foot shape type. This segmentation ensures that users receive recommendations from the appropriate product category, maintaining both product availability and comfort by matching foot shape characteristics with suitable shoe designs and materials.
Solution Approach 2:
The patent applies different product information characteristics to different user types: child product information for users with child foot shape and adult product information for users with adult foot shape. This local quality approach ensures that each user receives appropriately tailored recommendations, maintaining comfort and performance while providing relevant product options.

AI summary
A shoe purchase recommendation device 10A includes a user information acquisition unit that acquires user information including a first foot size that is a foot size of a user, a foot-size prediction unit that predicts, based on the first foot size of the user, a second foot size that is a foot size of the user at a future point of time, a growth-end determination unit that determines, based on the second foot size, whether foot growth of the user has ended at the future point of time, a product information storage unit that stores child product information and adult product information, a product information selection unit that selects, based on a result determined by the growth-end determination unit, product information regarding shoes from one of the child product information and the adult product information, and a display processing unit that displays the product information regarding shoes selected by the product information selection unit on a display unit.
