Solution Overview

Problem

Existing massage machines, particularly portable miniaturized ones, have limited massage functions and are unable to adapt to individual user preferences due to fixed massage forms and non-linear negative pressure generation, leading to reduced effectiveness and user satisfaction.

Innovation Solution

A combined massage device with a reciprocating motion portion that includes a functional end for independent massage functions, a piston structure for sucking massage, and a waterproof assembly, allowing for adjustable stroke and power modes to accommodate different user needs, along with a transmission component for power-driven reciprocating motion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a deformable closed cavity is used to generate negative pressure by changing cavity wall shape, then negative pressure massage function is achieved, but the function is limited after a period of time due to material fatigue and non-linear pressure generation

Engineering Contradiction:

Improvenegative pressure function durabilityVSAvoidmassage function adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The massage device is divided into a main body and a replaceable functional end. The functional end can be detached and replaced, allowing different massage functions (suction, massage, etc.) to be achieved by changing the functional end rather than relying on a single deformable cavity structure that degrades over time.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The functional end is designed with dynamic replaceability, allowing the massage device to adapt to different user needs by swapping functional ends. This dynamic configuration enables the system to maintain optimal performance over time through replacement rather than degradation.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a fixed massage form is used in portable miniaturized massage machines, then device portability is maintained, but the device cannot adapt to different user massage requirements

Engineering Contradiction:

Improvemassage requirement adaptabilityVSAvoiddevice structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is segmented into a standardized main body and interchangeable functional ends. This segmentation allows the main body to remain simple and portable while the functional ends provide diverse massage capabilities. Users can select different functional ends based on their needs without increasing the complexity of the main device structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The main body is designed as a universal platform that can accommodate multiple types of functional ends (suction functional end, massage functional end, etc.). This multi-functionality approach allows a single portable device to serve multiple massage requirements without requiring multiple separate devices, thus maintaining portability while enhancing adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If basic massage motion manner is used, then device simplicity is maintained, but different users have different massage strength and frequency requirements that cannot be met

Engineering Contradiction:

Improvemassage strength and frequency adaptabilityVSAvoidoperation simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The functional end is designed with adjustable parameters including stroke length, stroke frequency, and suction force. These dynamic adjustments allow the device to adapt to different user requirements for massage strength and frequency while maintaining a simple basic operation interface. Users can modify massage parameters according to their needs without complicating the overall operation.

Inventive Principle:

Principle #15Dynamics

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

The device provides a standardized massage solution with enhanced functionality, adaptability, and user customization, improving massage experience and reducing product development risks through multi-functionalization and stroke adjustment capabilities.

Implementation Method 1

when a piston of the reciprocating motion portion reciprocates, formed air pressure changes to form a sucking massage effect at the sucking port

Methodology Applied

Scientific EffectAir pressure change: Pressure Gradient

Implementation Method 2

at least one surface of the second cavity is a deformable surface and is configured to deform in response to an air pressure change in the second cavity

Methodology Applied

Scientific EffectPressure-induced deformation: Pressure Gradient
