Elliptical Massage Device with Ribbed Surface and Heat Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current massage devices fail to effectively relieve muscle tension and pain, particularly in the back, neck, and shoulders, and do not provide adequate heat retention for prolonged therapeutic benefits.
Innovation Solution
A massage device with an elliptical housing featuring a curved upper surface, central groove, inwardly facing ribs, upwardly facing ribs, and end zone ribs, along with a hollow cavity that can be filled with heat-retaining materials such as a mixture of silica and flaxseed, providing both pressure and heat for acupressure-like effects and increased blood flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a massage device applies pressure to relieve muscle tension, then therapeutic effect is improved, but the device structure becomes more complex
Solution Approach 1:
The massage device surface is segmented into multiple functional zones with different rib configurations: a central groove zone for spinal alignment, upwardly facing ribs for muscle compression, inwardly facing ribs for targeted pressure points, and end zone ribs for boundary areas. This segmentation allows each zone to perform its specific therapeutic function independently, improving overall therapeutic effectiveness while maintaining a relatively simple single-unit device structure.
Solution Approach 2:
Different regions of the massage device have locally optimized characteristics: the central groove provides a smooth recessed area for spine protection, while surrounding areas feature ribs of varying heights and orientations tailored to specific muscle groups. This local quality variation enables targeted pressure application to different anatomical regions without requiring multiple separate devices, thus improving therapeutic effect while avoiding excessive structural complexity.
2Duration of action of stationary object
If heat-retaining materials are added to the massage device, then heat retention is improved, but device weight increases
Solution Approach 1:
The patent utilizes phase change materials (paraffin wax) that undergo solid-liquid phase transitions at specific temperatures to store and release heat. By selecting materials with appropriate melting points and incorporating them into hollow cavities within the device structure, the system achieves extended heat retention duration without proportionally increasing overall device weight, as the phase change occurs within existing structural spaces.
3Ease of manufacture
If the massage device structure is simplified, then ease of manufacture is improved, but therapeutic effectiveness decreases
Solution Approach 1:
The patent combines multiple therapeutic functions into a single integrated massage device structure: posture support through the central groove, muscle compression through upwardly facing ribs, acupressure through inwardly facing ribs, and heat therapy through embedded heating elements in hollow cavities. This merging of functions into one device achieves comprehensive therapeutic effectiveness while avoiding the manufacturing complexity of coordinating multiple separate devices.

Function Achieved in This Case
The device effectively relieves muscle tension and pain by increasing blood flow, reducing central nervous system irritability, and promoting relaxation, while also improving posture and joint mobility through targeted pressure and heat application.

AI summary
A massage device has an elliptical shaped housing having an upper end and a lower end and sidewalls therebetween, an upper massage surface and a lower base surface, the upper massage surface having a curvature with a peak at substantially a middle section of the upper massage surface. A central groove runs through the upper massage surface. A row of inwardly facing ribs lines at least a part of the central groove so as to extend at least partially into or over the central groove, and a plurality of rows of upwardly facing ribs are formed on the upper massage surface between the inwardly facing ribs and the upper and lower ends respectively.
