Solution Overview

Problem

Conventional neck and shoulder massaging mechanisms have limited eccentric oscillating amplitude due to the interconnected nature of their assemblies, resulting in a less effective massage experience.

Innovation Solution

A neck and shoulder massaging mechanism with a housing, neck and shoulder massaging assemblies, an eccentric assembly, and a connection assembly driven by a motor, featuring a universal joint structure formed by spherical members and a ball connecting rod, allowing for larger eccentric oscillation amplitude and independent motion between the neck and shoulder assemblies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the neck massaging assembly and shoulder massaging assembly are connected through a connecting rod, then the structure is simple and integrated, but the eccentric oscillation amplitude of the neck massaging assembly is reduced

Engineering Contradiction:

Improvestructure simplicityVSAvoideccentric oscillation amplitude

Core Design Contradiction:

Device complexityVSLength of moving object

Solution Approach 1:

The patent divides the massaging system into independent neck and shoulder massaging assemblies that can oscillate separately. The neck massaging assembly is connected to the rotating shaft directly, while the shoulder massaging assembly is connected through a connecting rod, allowing each assembly to have its own oscillation characteristics without mutual interference.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connecting rod acts as an intermediary element that connects the neck and shoulder massaging assemblies. It allows the shoulder massaging assembly to oscillate independently while transmitting motion to the neck massaging assembly, thereby maintaining both structural integration and independent oscillation capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the neck massaging assembly is connected to the shoulder massaging assembly, then the overall structure is more stable, but the independent motion and oscillation amplitude of the neck massaging assembly are limited

Engineering Contradiction:

Improvestructural stabilityVSAvoidindependent motion capability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent employs dynamic connections through spherical cavities and spherical members that allow the massaging assemblies to move independently in different directions. The connecting rod can rotate and oscillate freely, enabling the neck and shoulder assemblies to have independent motion while maintaining overall structural stability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The spherical joint connection allows the connecting rod to serve multiple functions: it connects the neck and shoulder assemblies, allows independent oscillation of each assembly, transmits motion from the rotating shaft, and maintains structural stability. This multi-functional design resolves the contradiction between stability and independent motion.

Inventive Principle:

Principle #6Universality (Multi-functionality)
