Spherical Sacrum Cradle for Multidimensional Joint Mobilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing recurring pain in the lumbar, pelvic, and hip joints are inadequate, often relying on medications and traditional exercise equipment that fail to provide effective natural pain relief and improve flexibility and posture.
Innovation Solution
A multidimensional mobilization device with a concave upper surface and convex lower surface, featuring a recess to cradle the sacrum, made of materials like rubber, plastic, or wood, with a lip to limit tilt and pre-set patterns for enhanced movement, allowing for various therapeutic exercises such as tilting, rocking, and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional exercise equipment and techniques are used, then basic stretching and mobilization can be performed, but the depth of stretch and range of motion are insufficient to effectively relieve chronic pain
Solution Approach 1:
The device employs a spherical interface that contacts the sacrum, allowing multidimensional movement in all directions. The spherical geometry enables rotation, tilting, and rocking motions that provide greater range of motion compared to flat or planar exercise surfaces, directly addressing the limitation of insufficient stretching depth in traditional equipment
Solution Approach 2:
The invention transitions from two-dimensional stretching planes to three-dimensional mobilization by incorporating a spherical contact point that can move freely in multiple dimensions. This adds rotational and tilting degrees of freedom that were absent in traditional linear or planar exercise equipment, enabling deeper and more comprehensive joint mobilization
2Object-affected harmful factors
If medications are used to manage recurring pain, then pain relief can be achieved, but the need for ongoing medication use and potential side effects arise
Solution Approach 1:
The device enables users to perform self-mobilization and self-stretching exercises without requiring external intervention or medication. By providing the mechanical means for effective joint mobilization, the device allows the body's own movements and physiological processes to relieve pain, eliminating dependency on external substances while maintaining pain relief benefits
3Ease of operation
If a simple flat surface is used for exercises, then ease of use is maintained, but the ability to provide multidimensional mobilization and deeper stretches is limited
Solution Approach 1:
The spherical interface replaces the flat surface while maintaining ease of use through its simple geometric form. The sphere naturally facilitates multidimensional movement and can be easily integrated into existing exercise routines, providing enhanced mobilization capability without significantly complicating the user experience
Solution Approach 2:
The spherical device serves multiple functions simultaneously: it provides a stable support surface, enables rotational movement, facilitates tilting in multiple directions, and allows rocking motions. This multi-functionality is achieved through a single simple geometric form that can accommodate various exercise techniques and mobilization needs
