Modular Shiatsu Massager for Multi-Body-Area Use

Solution Overview

Problem

Existing massagers are limited to specific body areas, necessitating multiple purchases to cover all desired massage areas, increasing cost and storage needs.

Innovation Solution

A shiatsu massager with rotatable massaging members that is removably connectable to a handle or strap, allowing versatile application on various body parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a user purchases multiple massagers for different body areas, then the coverage of massage areas is improved, but the cost and storage space requirements increase

Engineering Contradiction:

Improvecoverage of massage areasVSAvoidnumber of massagers

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The massager head is designed with multiple massaging members that can be selectively positioned and attached to different body areas. The universal design allows a single massager unit to serve multiple functions across various body parts, eliminating the need for separate massagers for each area.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The massager head is divided into multiple independent massaging members (e.g., first and second massaging members) that can be selectively activated and positioned. This segmentation allows the user to target specific body areas with specific massaging members while keeping other areas unused, providing versatility without requiring multiple complete massager units.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If a user purchases multiple massagers for different body areas, then the coverage of massage areas is improved, but the storage space required increases

Engineering Contradiction:

Improvecoverage of massage areasVSAvoidstorage space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The massager head is designed with multiple massaging members that can be selectively positioned and attached to different body areas. The universal design allows a single massager unit to serve multiple functions across various body parts, eliminating the need for separate massagers for each area.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The massaging members are designed to be nested or storable within the massager head housing when not in use. This nesting capability allows the multi-functional massager to be compactly stored in a small space, maintaining versatility while minimizing storage requirements.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If a massager is designed with multiple massaging members for versatile use, then the adaptability to different body areas is improved, but the device complexity increases

Engineering Contradiction:

Improveapplication on various body partsVSAvoidstructure of massager

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The massager head is divided into multiple independent massaging members (e.g., first and second massaging members) that can be selectively activated and positioned. This segmentation allows the user to target specific body areas with specific massaging members while keeping other areas unused, providing versatility without requiring multiple complete massager units.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The massaging members are designed with rotational capability, allowing them to rotate independently during operation. This dynamic feature enables the same physical structure to adapt to different massage needs and body areas through motion rather than requiring multiple static configurations, reducing overall device complexity.

Inventive Principle:

Principle #15Dynamics
