Massage Head With Radial Converging Tips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin massage devices do not effectively work the skin and muscles of the face in a comprehensive, pleasant, and effective manner, lacking in optimizing skin pinching and muscle engagement.
Innovation Solution
A massage device with a motorized massage head featuring three or four massage tips that move in radial or curvilinear trajectories around a central point, allowing for alternating pinching and releasing motions, combined with a transmission mechanism that includes a guide system and cam system to control the tips' movement, and optional features like iontophoresis, wave emission, and cosmetic product dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If massage tips move in parallel planes to achieve skin pinching, then skin pinching is achieved, but the work on skin and muscles is not optimized
Solution Approach 1:
The massage tips are designed to move along radial trajectories that converge toward a central point, transitioning from static parallel movement to dynamic convergent movement. This allows the tips to alternately approach and recede from the center, creating an optimized pinching action that simultaneously engages skin and underlying muscles more effectively.
Solution Approach 2:
The massage tips are arranged in a three-dimensional configuration where they extend perpendicular to the application surface, and their movement occurs along radial trajectories in three-dimensional space rather than in parallel planes. This dimensional change enables the tips to converge toward a central point, creating a more effective pinching action that engages both skin and muscles.
2Device complexity
If massage tips are arranged to move in parallel planes, then the device structure is simple, but the massage effectiveness is limited
Solution Approach 1:
The transmission mechanism incorporates movable elements that allow the massage tips to dynamically change their positions along radial trajectories. This dynamic configuration, while more complex than static parallel arrangements, enables the tips to converge toward a central point, creating an optimized pinching action that simultaneously engages skin and underlying muscles more effectively.
3Productivity
If massage tips perform alternating back-and-forth movements towards center point, then skin pinching is optimized, but the transmission mechanism becomes more complex
Solution Approach 1:
The transmission mechanism is segmented into multiple independent components, each responsible for controlling the movement of individual massage tips. This segmentation allows for modular design and simplifies the overall mechanism by breaking down the complex coordinated movement of multiple tips into manageable separate control units.
Solution Approach 2:
The transmission mechanism is designed to produce periodic back-and-forth movements of the massage tips along radial trajectories. This periodic action, driven by oscillating or rotating elements, automatically creates the alternating approach and recession of tips toward the center point, optimizing skin pinching without requiring complex control systems.

AI summary
The apparatus (1) has an assembly unit arranged between a body (2) and a massage head (5). The head comprises an application surface and three massage ends that extend towards an outer side of the application surface. The massage ends are defined on the application surface according to concentric virtual circles with a center. The head comprises a transmission system that is pulled by a motor (3) and a motor reducer. The system brings the massage ends closer to each other and departs the massage ends from each other in two directions according to trajectories that meet at the center.
