Rehabilitation Apparatus with Counterweight Load Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rehabilitation methods for scoliosis and herniated disks are costly, inefficient, and uncomfortable, with existing devices failing to effectively reduce spinal and knee load during exercise, leading to prolonged treatment periods and low patient satisfaction.
Innovation Solution
A rehabilitation exercise apparatus featuring a body member with moving wheels and a load-support system that adjusts to reduce spinal and knee load by lifting the user's upper body using weights, combined with a waist protector and wire traction member for stable and comfortable exercise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rehabilitation methods are used, then treatment effectiveness is limited, but treatment costs are high and treatment periods are prolonged
Solution Approach 1:
The apparatus employs dynamic movement of the load support member to actively reduce spinal load during exercise, transitioning from static conventional methods to dynamic load management that enhances treatment effectiveness while reducing required treatment time
Solution Approach 2:
The load support member functions as a counterweight mechanism that offsets the user's body weight during exercise, creating a reduced-load environment that accelerates rehabilitation effectiveness and shortens treatment periods
2Speed
If user performs exercise with full body weight, then exercise intensity is maintained, but spinal and knee load increases causing pain
Solution Approach 1:
The load support member acts as a counterweight system that compensates for the user's body weight during exercise movements, allowing maintenance of exercise intensity while significantly reducing the harmful gravitational load on the spine and knees
Solution Approach 2:
The load support member serves as an intermediary between the user's body weight and the ground reaction force, mediating the load transmission to reduce impact on spinal and knee joints while preserving exercise effectiveness
3Reliability
If existing rehabilitation devices are used, then some support is provided, but load reduction effectiveness is insufficient
Solution Approach 1:
The load support member implements a counterweight mechanism that actively offsets body weight during exercise, providing superior load reduction effectiveness compared to existing rehabilitation devices that offer only passive support
Solution Approach 2:
The system transitions from static support structures to dynamic load compensation that actively adjusts during exercise movements, enhancing both support effectiveness and load reduction capability
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
The apparatus allows for reduced pain and improved exercise stability by distributing the user's weight, enabling effective rehabilitation exercises while walking, even for severely ill patients, with adjustable weight distribution for individual comfort and safety.
Implementation Method 1
weights corresponding to a weight of the user's upper body may be transmitted to the load support member as the load support member is rotated by a predetermined angle

AI summary
Disclosed herein is a rehabilitation exercise apparatus for the spine and knees. The rehabilitation exercise apparatus includes: a body member (110) configured such that moving wheels (115) are installed at bottoms of a pair of vertical frames (111, and 112) spaced apart from each other by a predetermined distance; a load-support member (130) coupled to the pair of vertical frames (111 and 112) in a height-adjustable manner, and coupled to the vertical frames (111 and 112); and a weight member (150) installed on one side of the lower portion of the body member (110) so that weights corresponding to the weight of the user's upper body can be transmitted to the load support member (130) as the load support member (130) is rotated by a predetermined angle. Accordingly, a user can take rehabilitation exercise while walking with the armpits, arms, or shoulders supported on the load support member (130).
