Solution Overview

Problem

Existing massage tools are cumbersome, require assistance, lack precision, and are not user-friendly for self-massage, especially for targeting specific areas like the back, shoulders, or neck, and fail to adjust pressure effectively for individualized treatment.

Innovation Solution

A self-massage tool with a simple construction featuring sliding and rotatable bodies with adjustable rolling discs, locking mechanisms, and interchangeable attachments for customizable pressure and orientation, allowing users to operate independently without external assistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional massage balls are used for self-massage, then the tool is simple and affordable, but the tool lacks precision in targeting specific areas and cannot maintain consistent pressure

Engineering Contradiction:

Improvesimplicity and affordabilityVSAvoidprecision in targeting specific areas

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The massage device is divided into multiple independent components: a handle, a mounting mechanism, and interchangeable massage heads with different shapes and sizes. This segmentation allows users to select specific heads for different body areas while keeping the overall device simple and affordable.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The device incorporates adjustable mechanisms that allow users to dynamically change the massage head position, orientation, and pressure applied. The mounting mechanism enables rotation and adjustment of the massage head angle, providing precision in targeting specific areas while maintaining device simplicity.

Inventive Principle:

Principle #15Dynamics

2Reliability

If motorized massage tools are used to provide deeper and more targeted massage, then the massage depth and targeting improve, but the tools become heavy, complex, and require assistance from another person

Engineering Contradiction:

Improvemassage depth and targeting effectivenessVSAvoidportability and ease of self-use

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The invention extracts the essential massage function from complex motorized systems and implements it through a simple mechanical device. By removing motors and electronic components, the device becomes lightweight and portable while maintaining effective massage depth through mechanical leverage and proper body positioning.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The device is specifically designed for independent self-use with an ergonomic handle and adjustable mounting mechanism that allows users to position and operate the massage heads on their own bodies without assistance. The lightweight construction enables easy handling and repositioning during self-massage sessions.

Inventive Principle:

Principle #25Self-service

3Ease of manufacture

If standard massage balls are used, then the tool is affordable and simple, but the tool rolls away easily and requires constant repositioning

Engineering Contradiction:

ImproveaffordabilityVSAvoidstability during use

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

While maintaining the rounded, comfortable shape of traditional massage balls, the invention adds a mounting mechanism that secures the massage head to the handle. This hybrid design preserves the affordable, simple aesthetic and tactile benefits of spherical massage tools while eliminating the rolling away problem through the mechanical connection to the handle.

Inventive Principle:

Principle #14Spheroidality (Curvature)

4Ease of manufacture

If existing massage tools are used, then the tools are available and simple, but the tools cannot adjust pressure for individualized treatment of different body areas

Engineering Contradiction:

Improveavailability and simplicityVSAvoidpressure adjustment capability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The device employs universal, interchangeable massage heads that can be used on different body areas with varying pressure requirements. The mounting mechanism allows adjustment of the massage head position and angle, enabling the same basic device to adapt to individualized treatment needs for different muscle groups and pressure tolerances.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a massage tool that includes a rod and a first body with an upper and lower part. The lower part of the first body is movably connected to the rod, allowing it to move along the length of the rod. The upper part has two arms that extend upward, with a rolling member mounted between them. The upper part can rotate relative to the lower part. A locking mechanism is connected to the lower part of the first body, capable of switching between a locked and an unlocked position. In the locked position, the first body is prevented from moving along the rod, while in the unlocked position, it is free to move. This design provides flexibility in adjusting the tool's position and functionality.
