Shoe and Insole Selection System Using 3D Foot Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face challenges in selecting appropriate shoes and insoles due to limited knowledge about anatomical fit, relying on subjective feedback, and lack of opportunity to try on products when purchasing online.
Innovation Solution
A system that compares 3D characteristics of consumer foot information with shoe and insole data to recommend compatible combinations, using image recognition and database comparisons to provide accurate and personalized recommendations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If consumers rely on subjective feedback and limited knowledge to select shoes and insoles, then the selection process is simple and quick, but the anatomical fit and long-term comfort are compromised
Solution Approach 1:
The patent introduces a sales worker as an intermediary who uses a specialized fitting system with multiple sensors to objectively measure foot characteristics and shoe/insole compatibility. This mediator bridges the gap between consumer subjective feedback and precise anatomical measurement, resolving the contradiction by providing accurate fit data without requiring the consumer to have expert knowledge.
Solution Approach 2:
The patent replaces the traditional mechanical trial-and-error fitting method with an automated sensor-based measurement system. Multiple sensors capture foot dimensions, pressure distribution, and movement characteristics, then a processor analyzes this data to objectively determine anatomical fit. This substitution transforms the simple but inaccurate consumer trial process into a precise measurement system.
2Reliability
If sales workers rely on consumer feedback to recommend shoes and insoles, then the process is straightforward, but the recommendations are unreliable due to uninformed consumer input
Solution Approach 1:
The patent implements a feedback mechanism where sensors continuously monitor foot characteristics and shoe/insole interaction, providing objective data back to the sales worker and system. This feedback loop replaces unreliable consumer subjective feedback with precise measurement data, enabling reliable recommendations while maintaining process efficiency through automated data collection and analysis.
Solution Approach 2:
The system enables self-service fitting where the measurement system automatically captures and analyzes foot data without requiring extensive worker intervention or consumer expertise. The sensors and processor work autonomously to generate fitting recommendations, improving both reliability through objective measurement and productivity by reducing manual assessment time.
3Ease of operation
If consumers purchase shoes and insoles online without trying them on, then the convenience and accessibility are improved, but the ability to ensure proper fit is lost
Solution Approach 1:
The patent creates a digital copy of the consumer's foot through sensor measurements, capturing three-dimensional characteristics, pressure distribution, and movement patterns. This digital footprint can be stored and used for online purchasing decisions, allowing consumers to maintain fit accuracy convenience by comparing their digital copy against virtual shoe and insole models without physical trial.
Solution Approach 2:
The system performs preliminary measurement and analysis of foot characteristics before the purchasing decision is made. By capturing accurate anatomical data in advance and using it to pre-screen compatible shoes and insoles, the system enables consumers to make informed online purchases with confidence, maintaining fit accuracy while enjoying purchasing convenience.
Data Source
AI summary
Embodiments are directed towards recommending a shoe and insole combination for a consumer. A variety of shoe information, insole information, and consumer foot information may be determined, which may include heel width, a width or shape, a length, a height, and arch characteristics. The foot information, the shoe information for a plurality of shoes, and the insole information for a plurality of insoles may be compared to determine at least one combination of shoe and insole that is compatible with the consumer's foot. Based on this comparison of foot information, shoe information, and insole information, a recommendation of at least one shoe and insole combination may be determined and provided to a user and/or the consumer.
