Chair-Integrated Exoskeleton Arm for Fast Left-Right Rehabilitation Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exoskeleton-type upper extremity rehabilitation robots require separate systems and lengthy setup processes for left and right conversions, leading to inefficient space utilization and prolonged training preparation times.
Innovation Solution
An exoskeleton-type rehabilitation robot system integrated with a chair, featuring a robot arm that can move left or right based on the user's position, with a conversion part, driving links, and a controller that automatically adjusts and controls the robot arm's position for efficient left and right driving modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system and chair are separated for left and right conversion, then the robot arm can be converted to different directions, but the position of the entire system must be adjusted and the setting process becomes complicated and time-consuming
Solution Approach 1:
The patent integrates the robot arm system with the chair into a unified structure where the robot arm is directly mounted on the chair backrest. This merging eliminates the need for separate system conversion procedures, allowing direction switching to be performed quickly by simply adjusting the robot arm position without moving the entire system, thereby reducing training preparation time while maintaining adaptability
Solution Approach 2:
The patent implements a dynamic conversion mechanism where the robot arm can be quickly repositioned between left and right directions through a simplified adjustment process. The system allows dynamic switching of driving modes without requiring complex static reconfiguration, enabling fast adaptation to different training directions
2Adaptability or versatility
If the guide for left and right direction conversion protrudes long to both sides, then the robot arm can be converted, but the setting process becomes complicated and requires a relatively large amount of space
Solution Approach 1:
The patent transitions from a horizontal extension approach (long guides protruding to both sides) to a vertical integration approach (robot arm mounted on the chair backrest). This dimensional change allows direction conversion to be achieved within a compact vertical space, eliminating the need for large horizontal space while maintaining full direction conversion capability
3Area of stationary object
If the system is integrated with the chair, then space utilization efficiency increases, but the robot arm position must be adjusted for different user body shapes
Solution Approach 1:
The patent designs the integrated robot arm system with universal adjustment capabilities that can accommodate different user body shapes through standardized positioning mechanisms. The system provides multi-functional adaptability, allowing the same integrated structure to serve various users by adjusting robot arm position and chair configuration, thereby maintaining space efficiency while managing adjustment complexity
