Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for alleviating finger and joint pain due to arthritis and arthrosis only provide vibration massage without simultaneously performing a stretching function, failing to address the need for a comprehensive treatment that can be applied without visiting a specialized center.
Innovation Solution
A device comprising two ferrules joined by a means to controllably modify the distance between them, generating a stable axial force and incorporating vibration-generating mechanisms, which can be adjusted for intensity, phase, and speed, to provide simultaneous massage and stretching without compressing the joint area, using programmable elastic means, shape memory materials, or air pressure for fixation and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If vibration massage is applied to the joint area, then pain relief is achieved, but compression of the joint area occurs which may worsen the disorder
Solution Approach 1:
The device applies stretching force to the joint area before applying vibration massage, creating space and reducing compression in the joint. This preliminary stretching action prepares the joint to receive vibration therapy without the harmful compression that would occur if vibration alone were applied.
Solution Approach 2:
The device dynamically adjusts between stretching and vibration modes, using programmable control to alternate or combine these actions. The stretching mechanism uses elastic elements that can be tensioned to pull the ferrules apart, creating dynamic movement that prevents static compression during vibration therapy.
2Shape
If stretching force is applied to correct deformation, then joint alignment improves, but additional mechanical stress is imposed on the joint
Solution Approach 1:
The device applies stretching force in periodic cycles rather than continuous static force. The programmable control system activates the stretching mechanism for specific durations, then allows relaxation periods. This periodic application corrects joint alignment through repeated gentle pulling actions while avoiding excessive cumulative mechanical stress.
Solution Approach 2:
The device uses programmable control to adjust stretching force parameters including magnitude, duration, frequency, and waveform. By varying these parameters, the system can apply sufficient force to correct joint alignment while staying within safe stress limits. The elastic elements provide progressive resistance that adapts to joint conditions.
3Adaptability or versatility
If a comprehensive treatment device is designed to perform multiple functions, then treatment effectiveness improves, but device complexity increases
Solution Approach 1:
The device merges stretching and vibration therapy functions into a single integrated unit. The stretching mechanism uses elastic elements connecting two ferrules, while vibration motors are mounted on these same ferrules. The programmable control system unifies the control of both functions, allowing them to work together synergistically without requiring separate devices.
Solution Approach 2:
The ferrules serve multiple functions: they provide attachment points for the elastic stretching elements, serve as mounting platforms for the vibration motors, and act as the interface with the patient's body. The control system is designed to manage both stretching and vibration modes through a single interface, enhancing versatility while managing complexity.
