Myofascial Massage Head Unit With Graded Membrane Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum-based massage devices lack effective mechanisms to prevent direct skin contact, which can cause pain and irritation, and existing solutions, such as using a membrane between the vacuum pump and skin, are inadequate.
Innovation Solution
The head unit incorporates a flexible membrane with graded protrusions that engage the body in a non-continuous manner, allowing for controlled application of force through varying heights and angles, ensuring minimal direct contact and maximizing treatment efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a membrane is placed between the vacuum pump and skin to prevent direct contact, then skin safety is improved, but the device complexity increases and the membrane may still cause pain and irritation
Solution Approach 1:
The patent uses a flexible membrane as an intermediary element between the vacuum pump and the skin. The membrane is designed with specific properties (flexibility, porosity) to allow vacuum transmission while preventing direct contact, thereby reducing skin irritation and pain caused by direct vacuum application.
Solution Approach 2:
The patent employs a flexible membrane (thin film) as the protective barrier. This flexible shell allows the vacuum force to be transmitted effectively while maintaining comfort and safety during skin contact, avoiding the harsh effects of rigid direct contact.
2Reliability
If a membrane is used to prevent direct skin contact, then safety is improved, but treatment efficacy may be reduced due to inadequate force application
Solution Approach 1:
The patent modifies the membrane's physical parameters (flexibility, porosity, thickness) to optimize the balance between safety and treatment efficacy. By carefully controlling these parameters, the membrane allows sufficient vacuum force transmission for effective treatment while maintaining safety through prevented direct contact.

AI summary
A myofascial massager for mechanical treatment of a treatment location in a human subject's body. The massager includes an actuator which operates in a cyclical linear amplitude field for a few millimeters and at a frequency range from some Hz to a few dozen Hz. A head unit connected to the actuator includes a first portion having a higher rigidity, and a membrane having a second lower rigidity, which membrane comes into contact with the treatment location.
