Solution Overview

Problem

Conventional massage sticks fail to fully engage the user's skin and internal tissues, leading to inadequate skin activation and blood circulation, and often result in blood stasis, thus not meeting current market requirements for massage devices.

Innovation Solution

A negative pressure massage device comprising a massage stick with an air channel and an external negative pressure device that produces alternating suction and relief effects through a communication pipe, reducing the stick's volume and weight, and allowing for easy cleaning and integration with heating and vibration features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the negative pressure generating component and pressure relief assembly are integrated into the massage stick, then the massage function is complete, but the volume and weight of the massage stick increase significantly

Engineering Contradiction:

Improveease of operationVSAvoidvolume of massage stick

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The massage device is divided into two independent parts: a lightweight massage stick and a separate negative pressure generating device. The massage stick contains only the air channel and openings, while the negative pressure generating component and pressure relief assembly are housed in a separate unit connected via communication pipe. This segmentation allows the massage stick to remain compact and easy to handle while still providing complete massage functionality through the external device.

3Ease of manufacture

If the air channel is sealed in the stick body, then the structure is compact, but the stick body cannot be cleaned easily

Engineering Contradiction:

Improvestructural compactnessVSAvoidcleanability of stick body

Core Design Contradiction:

Ease of manufactureVSEase of repair

Solution Approach 1:

The air channel structure transitions from a completely sealed design to a dynamic configuration with controllable openings. The negative pressure connection hole and air suction opening are designed to be accessible through the stick body surface, allowing the air channel to be connected to the external negative pressure device while remaining partially accessible for cleaning. This dynamic design enables both compact structure and easy maintenance.

AI summary

A negative pressure massage device which includes a massage stick, an external negative pressure device and a communication pipe. The massage stick includes a stick body, an air channel in the stick body, a negative pressure connection hole and an air suction opening formed at both ends of the stick body and communicated with the air channel. The external negative pressure device is installed separately from the massage stick and includes a housing and a negative pressure drive/control module. The negative pressure drive/control module includes a controller, a negative pressure generating component, a pressure relief assembly and an air pipe assembly with a negative pressure communication hole formed on the housing. The ends of the communication pipe are communicated with the negative pressure connection hole and the negative pressure communication hole. This disclosure provides various negative pressure massage effects and improves the ease of operation.
