Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional method for producing customized foot insoles requires high motor skills and specialized knowledge, is time-consuming, and involves complex modifications with plaster models that require a strict timeline for hardening, making the process inefficient and prone to errors.
Innovation Solution
A digital method using three-dimensional data processing to create and modify foot insole models by defining vectors and axes, allowing for rotation and torsion deformations to control foot phases, reducing the need for manual dexterity and timeline constraints, and enabling direct control of heel and forefoot positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a plaster model is used and modified by building up plaster, then the insole can be customized to correct foot movement, but the process requires great motor skills and specialist knowledge
Solution Approach 1:
The patent uses a digital three-dimensional copy of the foot morphology instead of a physical plaster model. This digital replica can be easily modified through software operations (rotation, torsion deformation) without requiring manual dexterity or specialist knowledge of plaster working, while still achieving precise customization for gait correction
Solution Approach 2:
The patent replaces the mechanical/manual process of building up and modifying plaster models with a digital computing system. The modification operations (rotation around axis, torsion deformation) are performed algorithmically through software rather than manually through physical manipulation, eliminating the need for motor skills and specialist knowledge
2Manufacturing precision
If plaster is built up on the model to modify it, then the insole can be customized, but this is a time-consuming task as the built up plaster takes a certain time to harden
Solution Approach 1:
The patent replaces the time-consuming physical process of plaster application and hardening with instantaneous digital operations. Model modifications are performed immediately through software commands (rotation, torsion) without any waiting time for material curing, dramatically reducing production time while maintaining customization precision
Solution Approach 2:
The patent performs all model modifications in the digital domain before production, allowing immediate visualization and adjustment of corrections without sequential waiting periods. The digital model can be iteratively refined and approved before any physical manufacturing begins, eliminating rework time
3Manufacturing precision
If a plaster model is used and modified, then the insole can be customized, but the insole is complex to make with regard to the actions and timetable to be followed
Solution Approach 1:
The patent uses a digital three-dimensional copy of the foot that can be manipulated through standardized software operations. This digital replica eliminates the need to follow complex physical procedures and timetables for plaster application, curing, and modification, simplifying the overall process while maintaining precise customization capability
Solution Approach 2:
The patent replaces the complex sequence of physical actions (plaster mixing, application, waiting for hardening, manual modification) with simple digital operations (loading data, rotating model, applying torsion). The computing system automatically manages the process without requiring adherence to strict timetables or complex procedural steps

AI summary
Method for producing a functional insole in which elements are defined on a digital model of a person's foot. By rotating these elements in relation to each other, a deformed model is obtained on the basis of which a functional insole can be produced which controls the foot in desired phases of the gait.
