Massage Assembly With Rotatable Head for Adaptive Acupoint Massage

Solution Overview

Problem

Existing massage devices for acupoints near the anus have limited massage modes and effects, necessitating improved adjustment and functionality to enhance therapeutic outcomes.

Innovation Solution

A massage assembly with a first massage head and rotation locking structure that allows for adjustable and locked/unlocked rotation angles, enabling various massage modes such as single and double bump pressing, friction, and adaptive angle adjustments to improve massage efficacy on acupoints near the anus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed massage head is used, then the device structure is simple, but the massage mode is single and cannot adapt to different acupoint shapes

Engineering Contradiction:

Improvemassage modeVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The massage head is designed with a rotatable connection to the massage arm, allowing it to rotate and swing dynamically. The rotation locking structure enables the massage head to be locked at different angles or unlocked to swing freely, transforming a static structure into a dynamic one that can adapt to different massage needs and acupoint shapes.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the massage head is fixed at a single angle, then the device structure is simple, but it cannot adapt to different shapes of acupoints like Huiyin acupoint

Engineering Contradiction:

Improveadaptive angle adjustmentVSAvoidrotation locking structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The massage head is designed with a rotatable connection to the massage arm, allowing it to rotate and swing dynamically. The rotation locking structure enables the massage head to be locked at different angles or unlocked to swing freely, transforming a static structure into a dynamic one that can adapt to different massage needs and acupoint shapes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The rotation locking structure allows the rotation angle of the massage head to be adjusted and locked at different positions. By changing the angular parameter of the massage head relative to the massage arm, the device can adapt to different acupoint shapes and positions, such as the Huiyin acupoint, without increasing overall device complexity.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If only pressing massage is provided, then the device structure is simple, but the massage effect is limited

Engineering Contradiction:

Improvemassage effectVSAvoidmassage modes

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The massage head is designed with a rotatable connection to the massage arm, allowing it to rotate and swing dynamically. The rotation locking structure enables the massage head to be locked at different angles or unlocked to swing freely, transforming a static structure into a dynamic one that can adapt to different massage needs and acupoint shapes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The massage head can perform periodic pressing and friction movements by rotating or swinging. When unlocked, the massage head swings back and forth to provide friction massage, while when locked, it provides steady pressing massage. This periodic action between different massage modes enhances the overall massage effect.

Inventive Principle:

Principle #19Periodic action
