Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for smart textiles are unable to perform real-time 3D reconstruction of shape deformation, limiting their applications in medical diagnostics, rehabilitation, entertainment, and engineering, as they primarily focus on 2D measurements and are prone to errors in interpreting textile stretching and bending.
Innovation Solution
An apparatus and process that utilize measurements of electromagnetic characteristics from conductive fibers in smart elastic textiles to perform real-time 3D reconstruction, aligning measurement points with a schematic 3D model, transforming electromagnetic data into distances, and iteratively calculating vertex positions to reconstruct the deformed geometry, allowing for accurate visualization of textile deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If 2D measurements are used for smart textiles, then device complexity is reduced, but measurement precision and ability to interpret textile stretching and bending accurately deteriorates
Solution Approach 1:
The patent transitions from 2D measurement to 3D reconstruction by using electromagnetic characteristics measured at multiple points on the textile surface. The system reconstructs three-dimensional deformation by calculating spatial coordinates (x, y, z) from electromagnetic field measurements, enabling accurate interpretation of textile stretching and bending in three-dimensional space while maintaining relatively simple sensor integration.
2Measurement precision
If real-time 3D reconstruction is implemented, then measurement precision and deformation analysis capability are improved, but device complexity and computational requirements increase
Solution Approach 1:
The patent replaces complex mechanical 3D measurement systems (such as multiple cameras or laser scanners) with electromagnetic field-based measurement. By measuring electromagnetic characteristics (capacitance, impedance) at textile nodes and using iterative mathematical algorithms, the system achieves real-time 3D reconstruction without requiring complex optical or mechanical measurement apparatus.
Solution Approach 2:
The patent creates a virtual 3D model that copies the physical textile's deformation state. The system measures electromagnetic characteristics on the actual textile and reconstructs a corresponding 3D digital model that mirrors the textile's shape and deformation in real-time, enabling accurate analysis without physically complex measurement equipment.
3Measurement precision
If electromagnetic characteristics are measured at multiple measurement points, then measurement precision and 3D reconstruction quality are improved, but quantity of measurements and processing time increase
Solution Approach 1:
The patent performs preliminary actions by pre-defining the textile's node structure and electromagnetic measurement points before deformation occurs. The system establishes the initial 3D coordinate system and measurement grid in advance, allowing rapid real-time reconstruction during deformation by only updating the positions of pre-identified nodes rather than creating measurements from scratch.

AI summary
The present invention is a real-time reconstruction of the textile surface after its deformation from measurements of the changes in electromagnetic characteristics of conductive fibres of elastic textiles. The invention allows the 3D reconstruction and tracking of changes in smart textile surface shape in real time with a computer-assisted analysis of the forces that affect the deformation. The latter can represent muscle activity (when the textile is designed in the form of a brace), scanning the surface of objects (when the textile is placed on the object), analysis of object movements (when they are placed on the textile), and analysis of forces stretching or contracting the textile (when textiles fixed between moving objects).
