Guide Robot System for Real-Time Gait Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for evaluating and correcting walking posture, or gait, struggle to provide real-time feedback for improving or maintaining walking ability, as they often rely on pressure sensors or IMUs mounted on shoes, which do not effectively facilitate immediate correction.
Innovation Solution
A guide robot system that projects a guide footprint based on pre-configured gait data, measures the user's footprint, and evaluates it using a scoring method, allowing for real-time analysis and correction of gait through a processor and memory-based apparatus, with optional features like image recognition and special effects for improved training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pressure sensors or IMUs are mounted on shoes to evaluate gait, then walking ability can be measured, but real-time feedback for immediate correction cannot be provided
Solution Approach 1:
The patent replaces mechanical pressure sensors and IMUs with an optical projection system that uses light to project guide footprints and cameras to capture foot position. This optical substitution enables real-time visual feedback without the delays inherent in mechanical sensing and processing systems
Solution Approach 2:
The system creates a visual copy of the ideal gait pattern by projecting guide footprints that represent correct foot placement positions. Users can immediately see and compare their actual foot position against this visual copy, enabling real-time correction without waiting for processed sensor data
2Measurement precision
If specialized equipment like pressure plates or shoe shape analysis is used, then gait evaluation accuracy improves, but ease of operation deteriorates due to requiring special footwear or equipment
Solution Approach 1:
The system allows users to perform gait evaluation using their own regular shoes without requiring specialized equipment. The projection system and camera work with any footwear, making the user serve their own evaluation needs with equipment they already possess
Solution Approach 2:
The optical projection system is designed to work universally with any type of footwear rather than requiring specialized shoes or pressure-sensitive equipment. The camera captures foot position regardless of shoe type, making the system applicable to all users without restriction
