Head Massager Conical Motion via Spherical Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head massagers provide inadequate comfort during massage due to inefficient rotation mechanisms and lack of simulation of human hand movements.
Innovation Solution
A head massager design featuring a housing with a power source, driving wheels, massage head assemblies, and push components connected via a spherical hinge, where the driving wheels rotate around a first axis, and the push components tilt relative to this axis, allowing the massage heads to rotate in a conical path, simulating human hand grasping and kneading motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drive mechanisms are driven to rotate by the power source by means of gear sets, then the massage heads are driven to horizontally rotate, but the massaging comfort degree is bad
Solution Approach 1:
The patent introduces a spherical hinge connection between the massage head assembly and housing, replacing the traditional horizontal rotation mechanism. The massage head rotates around a vertical axis passing through the spherical hinge center, enabling conical motion trajectory that simulates human hand massage movements, thereby improving massaging comfort degree
Solution Approach 2:
The patent employs a push component with a tilted rotating trail that forms a cone or conical surface. As the driving wheel rotates, the push component drives the massage head assembly to rotate dynamically around the spherical hinge center, creating a conical motion path that mimics the natural grasping and kneading movements of human hands
2Adaptability or versatility
If the massage head assembly is driven to horizontally rotate by the drive mechanisms, then the massage heads can rotate, but they cannot simulate human hand movements
Solution Approach 1:
The spherical hinge connection enables the massage head to rotate around a vertical axis, creating a conical motion trajectory. This curved motion path closely simulates the natural grasping and kneading movements of human hands, significantly improving the adaptability and versatility of the massager
Solution Approach 2:
The patent transitions from horizontal rotation in one dimension to conical motion in three dimensions. The massage head assembly rotates around the spherical hinge center while maintaining a tilted angle, creating a conical surface trajectory that adds vertical and radial dimensions to the motion, better replicating human hand massage patterns

AI summary
A head massager including a housing, a power source, at least one driving wheel, at least one massage head assembly and at least one push component. The power source is fixed in an inner side of the housing, the at least one driving wheel is driven to rotate around a first rotation axis by the power source, and the at least one massage head assembly is located below the at least one driving wheel. The massage head assembly is driven to rotate around the center of the spherical hinge by the at least one push component arranged aslant, which simulates human hands' grasping and kneading operation and improves the massaging comfort degree.
