Pelvis Realignment Device with Spherical Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices fail to effectively realign the misaligned joints in and around the spine and pelvis, leading to lower back and pelvic pain, as they do not adequately address the complex biomechanical issues of joint misalignment and its impact on ligament and muscle positioning.
Innovation Solution
A device with a pair of arms connected by a spherical connection member allowing relative rotation and movement, enabling the realignment of the pelvis by repositioning the sacral and iliac joints, thereby correcting the posture and stabilizing the sacroiliac, L5/S1, and hip joints through specific exercises and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a device uses fixed rigid arms to apply force to the pelvis, then the structure is simple and stable, but it cannot adapt to the complex multi-directional movements needed for effective joint realignment
Solution Approach 1:
The device employs dynamic connections between arms that allow relative movement and rotation. Specifically, the connection between arms includes rotational joints enabling the arms to move relative to each other in multiple directions, allowing the device to adapt to the complex biomechanics of pelvic realignment while maintaining a relatively simple overall structure
Solution Approach 2:
The device divides the pelvic realignment function into multiple independent arms that can move and rotate relative to each other. Each arm can be positioned and oriented independently to address specific joint misalignments, providing versatility without requiring a completely complex integrated structure
2Ease of operation
If a device uses simple fixed connections between arms, then the device structure is simple, but it cannot achieve the multi-axis rotation and positioning required for effective pelvic realignment
Solution Approach 1:
The connection mechanisms between arms are designed with rotational degrees of freedom, allowing the arms to dynamically adjust their relative positions. This enables the device to achieve complex multi-axis positioning and rotation necessary for effective pelvic realignment while maintaining operational simplicity through natural mechanical movement
3Reliability
If existing devices are used for pelvic realignment, then the device structure is simple, but they fail to effectively address the complex biomechanical issues of joint misalignment and its impact on ligament and muscle positioning
Solution Approach 1:
The device incorporates dynamic rotational connections that allow it to adapt to and effectively address the complex biomechanics of pelvic realignment. The ability of arms to rotate and move relative to each other enables proper positioning to address joint misalignment and its impact on ligament and muscle positioning, improving realignment reliability
Solution Approach 2:
The device segments the realignment function into multiple independently movable arms, each capable of addressing specific aspects of joint misalignment. This segmentation allows the device to effectively tackle the complex biomechanical issues through coordinated movement of multiple components rather than a single rigid structure
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 device effectively reorients the pelvis into a neutral position, reducing the risk of pathological injury by repositioning ligaments and muscles, improving biomechanical performance and stability, as evidenced by positive effects on tests like the Gillet's test and adduction lift test.
Implementation Method 1
a pair of arms including an upper arm and a lower arm connected together at one end of each arm by a connection allowing relative rotation of the two arms in a plane passing through the longitudinal axes of both arms
Implementation Method 2
connected together at one end of each arm by a connection allowing relative rotation of the two arms in a plane passing through the longitudinal axes of both arms and also about an axis at right angle to said lower arm and passing through the connected ends of the arms
