Adjustable Roller Massage System with Counterbalancing Springs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massage devices require user effort to apply pressure, leading to fatigue and inconsistent massage quality, as the amount of force applied can vary significantly across different body parts, making it difficult to effectively massage all areas uniformly.
Innovation Solution
A roller massage system with adjustable pairs of roller assemblies and handle supports that allow the rollers to transition between a closed and open position, maintaining a parallel opposed relation, enabling uniform engagement with massageable body parts and allowing users to adjust the distance between rollers for varying body shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional roller massage device is used, then the user can apply pressure to the body, but the user experiences fatigue and the force applied varies significantly across different body parts
Solution Approach 1:
The patent employs springs as elastic elements that provide counterbalancing force to support the weight of the roller assemblies. This allows the rollers to maintain contact with the body surface without requiring the user to continuously apply downward force, thereby reducing user fatigue while maintaining consistent pressure across different body parts.
Solution Approach 2:
The roller assemblies are designed to automatically adjust their position and pressure application through the elastic elements. The system self-regulates the contact force between rollers and body, eliminating the need for constant user intervention and ensuring consistent massage quality across various body contours.
2Adaptability or versatility
If the roller distance is fixed, then the device structure is simple, but the device cannot adapt to various body curvatures and shapes
Solution Approach 1:
The patent incorporates adjustable mechanisms that allow the distance between roller assemblies to be dynamically changed according to different body parts. The handle supports and connection elements enable the roller spacing to be modified, providing adaptability to various body curvatures while maintaining reasonable structural simplicity.
3Force
If the user applies force manually, then pressure can be exerted on the body, but the force varies to a greater or lesser degree on different body parts
Solution Approach 1:
The springs provide a consistent elastic force that compensates for variations in body contours. This elastic counterbalancing mechanism ensures uniform pressure distribution across different body parts, eliminating the inconsistency caused by manual force application while maintaining adequate massage pressure.
