Eccentric Massage Mechanism for Composite Reciprocating and Rubbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massagers are limited by single power mechanisms, leading to single massage actions, resulting in poor comfort during actual use.
Innovation Solution
A massage mechanism with a bracket and three massage portions, each connected eccentrically to a driving mechanism with misaligned connection points, allowing for independent reciprocating and staggered rubbing actions through synchronized gear rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single power mechanism is configured, then the device complexity is reduced, but the massage action becomes single and comfort is poor
Solution Approach 1:
The single power mechanism is segmented into multiple independent power mechanisms (first power mechanism and second power mechanism), each driving separate massage portions. This segmentation allows different massage actions to be performed simultaneously on different body parts, improving massage comfort without requiring a completely complex integrated system.
Solution Approach 2:
Each power mechanism is designed with multi-functionality, where the first power mechanism can drive the first massage portion for reciprocating massage and the second power mechanism can drive the second massage portion for rubbing massage. This multi-functionality allows a single device to provide multiple massage actions, enhancing comfort while managing complexity through modular design.
2Ease of operation
If multiple massage portions with different actions are integrated, then massage comfort is improved, but the device complexity increases
Solution Approach 1:
The driving mechanism is segmented into independent first and second power mechanisms, each with its own motor and transmission system. This segmentation allows complex massage actions to be achieved through multiple simple, independent units rather than one complex integrated system, improving comfort while managing overall complexity.
Solution Approach 2:
The patent employs a nested structure where the first and second massage portions are arranged concentrically within the same housing space. The first massage portion is located in the inner region while the second massage portion is in the outer region, allowing multiple massage functions to be nested within a compact form factor, thereby improving comfort without proportionally increasing external device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables composite massage actions, enhancing comfort and effectiveness by simultaneously achieving reciprocating and rubbing motions on human body parts.
Implementation Method 1
the first massage portion, the second massage portion, and the third massage portion are respectively eccentrically connected to the driving mechanism, and the eccentric connection points of the second massage portion and the third massage portion on the driving mechanism are arranged at an angle misalignment
