Solution Overview

Problem

Existing massage devices are limited in their ability to stimulate a large area, making it difficult to achieve the desired massage effect.

Innovation Solution

A massage device with a housing and a massage assembly that includes a driving assembly with a driving source, driving wheel, and driven wheel, which rotates a massage member to create a kneading effect on a larger area of the human body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If a motor is used to drive the massage head to frequently beat, then the massage device can stimulate a small area, but the stimulation area is limited and cannot achieve desired massage effect

Engineering Contradiction:
Improvestimulation areaVSAvoidmassage effect
Core Design Contradiction:
Area of moving objectVSEase of operation

Solution Approach 1:

The massage member is divided into multiple protrusions distributed along its circumference, with each protrusion acting as an independent stimulation element. This segmentation allows the massage member to cover a larger area while maintaining effective stimulation through multiple contact points simultaneously

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The massage member transitions from a single-point beating mechanism to a multi-point rotational mechanism. By rotating the massage member with protrusions around the massage head, the system expands stimulation from one dimension (linear beating) to two dimensions (circumferential rotation), significantly increasing the covered area

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
