Configurable Massage Roller Wheels for Muscle-Specific Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massage rollers are specialized for specific muscle groups and do not accommodate varying body sizes, leading to inadequate engagement with bony prominences and discomfort, necessitating multiple purchases for comprehensive muscle group access.
Innovation Solution
A user-configurable massage roller system with interchangeable wheels of varying sizes and configurations, including handles and wall mounts, allowing customizable pressure application for different body sizes and muscle groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional specialized rollers are used for specific muscle groups, then targeted massage effect is improved, but device versatility deteriorates requiring multiple purchases
Solution Approach 1:
The massage roller is divided into multiple independent wheel segments that can be selectively arranged. Each wheel can be independently positioned on the shaft, allowing users to configure different combinations for different muscle groups and body sizes, thus providing both specialized effectiveness and overall versatility.
Solution Approach 2:
The system provides a universal massage roller platform that can perform multiple functions through interchangeable wheels. A single base unit with various wheel types (different diameters, textures, and configurations) can address all major muscle groups across different body types, eliminating the need for multiple specialized rollers.
2Ease of manufacture
If fixed geometry rollers are used, then manufacturing simplicity is improved, but adaptability to different body sizes deteriorates
Solution Approach 1:
The roller system transitions from a fixed geometry to a dynamic, reconfigurable structure. Wheels of different sizes and types can be arranged in various configurations on the shaft, allowing the roller to adapt its geometry to match different body sizes and shapes while maintaining relatively simple manufacturing of individual components.
3Device complexity
If cylindrical roller surface is used, then structural simplicity is improved, but engagement with bony prominences deteriorates causing discomfort
Solution Approach 1:
Different sections of the roller (individual wheels) have different surface qualities, diameters, and configurations tailored to specific body regions. For example, smaller wheels with smoother surfaces can be positioned for bony areas like the spine, while larger textured wheels can be used for broader muscle groups, optimizing both comfort and effectiveness.
Solution Approach 2:
The continuous cylindrical surface is segmented into discrete wheel units that can be independently selected and positioned. This allows users to create customized configurations that avoid bony prominences by selecting appropriate wheel sizes and spacings for different body regions.

AI summary
A therapeutic massage roller system includes a shaft extending from a first end to a second end, the shaft acting as an axle; wheels, each of the wheels including a channel to engage with the shaft and an exterior contact surface, the wheels including at least a first size and a second size; the shaft receives a user selection of the wheels to create a custom arrangement of one or more of the wheels.
