Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices for relaxing the spine are bulky, difficult to move, and require significant setup time, limiting their usability in real-life scenarios.
Innovation Solution
A medical device comprising a chair or waist protector with armpit supports, adjustable springs, and elastic bands that provide spinal relaxation and posture correction, featuring easy-to-use fastening mechanisms and adjustable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional spine relaxing device with guide columns, motors, and chains is used, then spinal relaxation function is achieved, but the device becomes bulky and difficult to move
Solution Approach 1:
The patent extracts and removes the bulky mechanical components (guide columns, motors, chains, rollers) from the spine relaxing device, retaining only the essential functional elements (armpit supports with springs and bars) that can provide spinal relaxation through a simplified mechanism
Solution Approach 2:
The invention replaces complex, heavy, durable mechanical structures with simpler, lighter components that achieve the same therapeutic effect through a different mechanism, prioritizing portability and ease of use over industrial-grade durability
2Reliability
If a traditional spine relaxing device is used, then spinal relaxation is achieved, but significant setup time is required
Solution Approach 1:
The device is segmented into independent, easily assembled components (waist protector, armpit supports, elastic bands) that can be quickly put together and taken apart, eliminating the need for complex setup procedures
Solution Approach 2:
The armpit supports are pre-configured with springs and bars in a compact form that automatically engages with the waist protector and user body, eliminating the need for step-by-step assembly during usage
3Stability of the object's composition
If fixed armpit supports are used, then structural stability is maintained, but adaptability to different users is reduced
Solution Approach 1:
The armpit supports incorporate springs that allow dynamic adjustment of position and pressure, enabling the fixed structural components to adapt to different user sizes and positions while maintaining stability through elastic deformation
Solution Approach 2:
The spring constants and pre-compression forces can be varied to change the mechanical properties of the armpit supports, allowing the same structural component to provide different levels of support and pressure for different users
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 reduces spinal load and corrects posture by relaxing the spine, being portable and easy to use in daily life.
Implementation Method 1
a first spring disposed in the cylinder and configured to protrude upward out of the cylinder when being rotated in one direction; a second spring coupled to an upper end of the first spring
Implementation Method 2
a second spring coupled to an upper end of the first spring and having a spring constant smaller than a spring constant of the first spring
Implementation Method 3
an elastic waist band configured to be wrapped around the waist of a user; an elastic connection band configured to connect the first ring and the second ring to each other

AI summary
Proposed is a medical device for relaxing the spine that is easy to move and keep and can be easily used in real life. The medical device for relaxing the spine include a chair having a seat and a back, a first armpit support disposed at a left side of the chair, and a second armpit support disposed at a right side of the chair, in which the first armpit support and the second armpit support each include a cylinder vertically coupled to the chair, a first spring disposed in the cylinder and configured to protrude upward out of the cylinder when being rotated in one direction, a second spring coupled to an upper end of the first spring and having a spring constant smaller than a spring constant of the first spring, a bar disposed over the second spring and configured to come in close contact with an armpit.
