Solution Overview

Problem

Existing manual massagers have massage heads of uniform size and shape, failing to accommodate individual preferences for massage intensity and requiring significant hand strength, leading to user fatigue.

Innovation Solution

A multi-corner massager with a polygonal pyramid structure featuring multiple support surfaces and massage parts of varying shapes and sizes, allowing for customizable massage intensity and reduced hand effort through attachment to surfaces for support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If massage heads are made uniform in size and shape, then manufacturing is simplified, but user comfort and effectiveness deteriorate due to inability to accommodate different massage preferences

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidmassage head variety

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The massager body is divided into multiple independent massage heads, each with different shapes and sizes. This segmentation allows each massage head to be optimized for specific massage needs while maintaining overall manufacturing efficiency through modular design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the massager body are equipped with massage heads having distinct local characteristics (different shapes and sizes). This local quality variation enables users to select appropriate massage heads for different body parts and massage preferences, resolving the contradiction between manufacturing simplicity and adaptability

Inventive Principle:

Principle #3Local quality

2Force

If strong massage pressure is applied, then massage effectiveness is improved, but user fatigue increases due to required hand strength

Engineering Contradiction:

Improvemassage pressureVSAvoiduser fatigue

Core Design Contradiction:

ForceVSEase of operation

Solution Approach 1:

The massager utilizes the user's body weight as a counterbalance to generate strong massage pressure. By positioning the massager body and applying body weight, users can achieve deep tissue massage without exerting excessive hand force, thereby improving massage effectiveness while reducing operational fatigue

Inventive Principle:

Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The design replaces the traditional hand-powered mechanical pressing system with a body-weight-based mechanical system. This substitution leverages the user's overall body mass rather than localized hand strength, enabling strong massage pressure with minimal hand effort and reduced fatigue

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A multi-corner massager comprises a main body, wherein the main body is composed of a plurality of support surfaces used for contacting a support and supporting the main body, the support surfaces are connected in pairs to form a polygonal pyramid structure, and the joint between two adjacent support surfaces is formed into an arc-shaped massage edge; each vertex of the polygonal pyramid structure is set as a massage part protruding outward, and all massage parts have different shapes and sizes.
