Solution Overview

Problem

Conventional massage techniques require a bed, occupying significant space, whereas a portable and space-efficient solution is needed for back massages.

Innovation Solution

A foldable massage chair design featuring a face pillow assembly, chest pillow assembly, handrail assembly, seat cushion assembly, back support rod, kneeboard assembly, and frames that can be easily assembled and disassembled for stability and portability, allowing users to comfortably receive massages while minimizing space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a bed is used for back massages, then massage comfort is improved, but space occupation increases

Engineering Contradiction:

Improvemassage comfortVSAvoidspace occupation

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The massage chair is divided into multiple independent components including front support piece, back supporting frame, seat cushion assembly, and various pillow assemblies that can be separated and stored individually, reducing space occupation while maintaining massage functionality

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The chair employs rotatable connections between components allowing it to transform between expanded working position and collapsed storage position, enabling space efficiency without sacrificing massage comfort when in use

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a foldable design is implemented, then portability is improved, but structural stability may worsen

Engineering Contradiction:

ImproveportabilityVSAvoidstructural stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The triangular support configuration is pre-designed into the expanded structure, automatically providing structural stability when the chair is set up, while the rotatable connections are pre-configured to enable easy folding for portability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The chair utilizes rotational movement in a different dimension to achieve folding, allowing the structure to collapse vertically while maintaining horizontal stability during use, thus achieving both portability and structural integrity

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A foldable massage chair, including a face pillow assembly for supporting the head, a chest pillow assembly for supporting the chest, a handrail assembly for supporting wrists, a front support piece, a seat cushion assembly, a back support rod, a kneeboard assembly, a back supporting frame, and a front supporting frame. When a user needs to use this chair, it is placed in an expanded or use position, so the user may sit on the seat cushion and lean on the massage chair, completely exposing his back, waist, and hips for a masseur to massage. When the chair needs to be put away, it is possible to fold down the chair into a collapsed position by folding the seat cushion assembly, front support piece, chest pillow assembly, and handrail assembly. Also, the front supporting frame is folded towards the back supporting frame. Consequently, the size of the entire chair decreases.
