Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing massage devices often have fixed headrests that do not correspond to the user's head position, leading to discomfort and inefficiency in providing effective massage therapy.

Innovation Solution

A massage device with a rotatable back frame and seat frame connected by a deformable rail system, featuring a support unit with guide rollers and a reinforcing member, allowing the massage module to move along the rail and adjust its position to accommodate different user postures, thereby providing a customizable massage experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the back frame is made rotatable to adjust to different user postures, then adaptability is improved, but structural stability deteriorates

Engineering Contradiction:

Improveadaptability to different user posturesVSAvoidstructural stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The back frame is designed to be rotatable relative to the seat frame, allowing dynamic adjustment between upright and reclined positions to accommodate different user postures and massage needs

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The frame is divided into separate rotatable segments (seat frame and back frame) connected by a rail system, allowing independent movement while maintaining overall structural integrity through the support unit

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the rail is made deformable to follow frame rotation, then adaptability is improved, but structural strength deteriorates

Engineering Contradiction:

Improveability to follow frame rotationVSAvoidstructural strength

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The rail is designed as a flexible component that can deform and follow the rotation of the back frame, allowing the massage module to maintain its moving path while the frame changes position

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The support unit combines multiple components (first link, second link, connection link, guide roller) to create a composite structure that provides both flexibility for rail deformation and sufficient strength to support the system

Inventive Principle:

Principle #40Composite materials

3Reliability

If the support unit is added to support the rail, then reliability is improved, but device complexity deteriorates

Engineering Contradiction:

ImprovedurabilityVSAvoidstructural complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The support unit acts as an intermediary mechanism between the rotatable frame and the flexible rail, providing necessary support and guidance while allowing the rail to deform during frame rotation

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The support unit is divided into separate functional components (links and guide roller) that can be independently manufactured and assembled, making the complex structure more manageable and maintainable

Inventive Principle:

Principle #1Segmentation
