Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for designing and generating customized footwear, including insoles, are time-consuming, expensive, and do not adequately account for the dynamic nature of the foot or the intended use, failing to provide personalized and effective solutions for individual consumers.
Innovation Solution
A system and method that uses a data capture device connected to a network to generate and store 3D scans of an individual's feet, incorporating data about their shoes, to produce customized insoles and footwear, ensuring accurate fit and functionality through retaking scans until they meet quality thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional scanning methods are used to create customized insoles, then the scanning process can be completed, but the scanning does not capture adequate positional data to account for the dynamic nature of the foot
Solution Approach 1:
The system captures multiple scans of the foot in different positions and states (resting, weight-bearing, moving) to account for the dynamic nature of the foot. This allows the insole design to accommodate foot deformation and movement during various activities, improving measurement precision without requiring overly complex specialized scanning equipment.
Solution Approach 2:
The system performs preliminary scanning to capture the foot's static structure, then uses this baseline data to guide subsequent weight-bearing and dynamic scans. This preliminary action allows the system to identify areas of interest and focus additional scanning resources accordingly, improving data accuracy while managing system complexity.
2Manufacturing precision
If conventional customized insole design systems are used, then insoles can be produced, but the process is time-consuming and expensive
Solution Approach 1:
The system creates digital 3D copies of the foot from multiple scans, allowing for virtual manipulation, analysis, and insole design before physical production. This digital copying process enables precise customization without requiring repeated physical measurements or manual mold-making, significantly reducing production time while maintaining high manufacturing precision.
Solution Approach 2:
The scanning system is designed to perform multiple functions using the same hardware: capturing static foot structure, weight-bearing deformation, and dynamic movement patterns. This multi-functionality eliminates the need for separate specialized scanning devices for each measurement type, reducing overall system cost and complexity while maintaining high customization accuracy.
3Adaptability or versatility
If conventional scanning systems are used, then foot scans can be obtained, but the scans do not adequately account for how the user intends to wear the insoles
Solution Approach 1:
The system captures foot scans in multiple dynamic states including resting position, weight-bearing on different surfaces, and during movement. This dynamic scanning approach allows the insole design to adapt to various intended uses and wearing conditions without requiring complex scenario-specific scanning equipment for each use case.
Solution Approach 2:
The scanning system varies key parameters such as load magnitude, surface type, and movement intensity to capture how the foot deforms under different conditions. By systematically changing these parameters, the system gathers comprehensive data about foot behavior across multiple usage scenarios, improving insole adaptability without significantly increasing device complexity.
