Motorized Walking Rehabilitation Device for Paralyzed Muscle Atrophy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rehabilitating paralyzed individuals to walk again is challenging due to the difficulty in supporting their muscles properly, requiring extensive assistance and resources, which can lead to muscle atrophy.
Innovation Solution
An exercise device with two units, including back rests, braces, handles, foot pedals, and a reduction electric motor, allows paralyzed individuals to stand and move their arms and legs in a walking pattern without external assistance, exercising muscles and preventing atrophy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual support methods are used to help paralyzed individuals walk, then the individual can be supported during movement, but it requires a large number of people and is difficult to support the individual's muscles properly
Solution Approach 1:
The device enables paralyzed individuals to perform walking rehabilitation independently without requiring multiple assistants. The motorized system provides the necessary support and movement, allowing the user to self-administer the rehabilitation therapy while the device handles all supporting functions.
Solution Approach 2:
The patent replaces the mechanical system of human assistants physically supporting the patient with an automated motorized system. Electric motors and mechanical linkages substitute for human strength and coordination, providing controlled movement and support that was previously only achievable through multiple people.
2Ease of operation
If extensive manual assistance is provided during rehabilitation, then the individual can be supported during exercise, but the rehabilitation process becomes long and hard requiring large number of people
Solution Approach 1:
The device enables paralyzed individuals to perform walking rehabilitation independently without requiring multiple assistants. The motorized system provides the necessary support and movement, allowing the user to self-administer the rehabilitation therapy while the device handles all supporting functions.
3Reliability
If paralyzed individuals remain immobile, then they avoid the difficulties of rehabilitation, but they experience muscle atrophy
Solution Approach 1:
The patent replaces the mechanical system of human assistants physically supporting the patient with an automated motorized system. Electric motors and mechanical linkages substitute for human strength and coordination, providing controlled movement and support that was previously only achievable through multiple people.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates muscle exercise and rehabilitation, reducing the need for multiple assistants and shortening the rehabilitation process by enabling independent muscle activation and mobility training.
Implementation Method 1
A reduction electric motor is used to power the exercise device
Data Source
AI summary
An architecture is presented that provides an exercise device for rehabilitation. The exercise device comprises at least two handles for securing hands of a user; a front rest and a back rest to position a body of the user; and at least two foot pedals for securing feet of the user. A reduction electric motor is used to power the exercise device. Additionally, the exercise device is fitted with wheels to allow the device to be moved. Typically, a user is lifted to a standing position and positioned between the back rest and front rest and secured. The user's hands are then secured to the handles via gloves and the user's feet are secured to the foot pedals via straps. The device is then powered on to exercise muscles of the user.
