Handheld Massaging Device with Segmented Elements for Skin Stress Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld massaging devices often have limited effectiveness, are power inefficient, and difficult to handle due to excessive force loads on the skin, which can lead to skin stress and cumbersome operation.
Innovation Solution
A handheld massaging device with a massaging surface comprising multiple massaging elements that apply simultaneous pinching and stretching forces to the skin, with a mechanical system allowing relative movement between these elements to create a localized massaging effect without a net external force, reducing power consumption and improving handling ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high force-load is applied to massage the skin effectively, then the massaging effect is improved, but the skin stress and power consumption increase
Solution Approach 1:
The massaging surface is divided into multiple independently movable massaging elements (rollers, pins, or vibrating elements) that can move relative to each other. This segmentation allows localized force application to specific skin areas, achieving effective massaging while distributing the overall force load to reduce skin stress and power consumption.
2Force
If counteracting massaging surfaces are used to balance forces, then force balance is achieved, but the device becomes cumbersome and difficult to handle
Solution Approach 1:
The massaging elements are designed to move dynamically relative to each other during operation (through rotation, reciprocating motion, or vibration). This dynamic movement creates force balance through motion rather than through static counteracting surfaces, eliminating the need for cumbersome balancing structures and improving device portability and ease of handling.

AI summary
A massaging device (100) with a massaging surface and a plurality of massaging elements (101, 102, 103) moveable relative to each other; characterized in that the massaging surface is adapted such that when applying the massaging surface to a skin surface (111) and moving the massaging elements (101, 102, 103) relative to each other, two differently directed forces are simultaneously exercised by the massaging elements (101, 102, 103) on the skin surface (111) thereby causing simultaneous pinching and stretching of the skin surface (111) present in between the massaging elements (101, 102, 103).
