Hinged Leg Ring with Adjustable Massage Balls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massaging devices do not effectively provide adjustable intensity and comprehensive massage coverage for the leg, particularly in terms of accommodating different leg sizes and user preferences for pressure.
Innovation Solution
A leg ring with a hinged design that forms a closed loop to surround the leg, integrated with a plurality of balls that can be adjusted in pressure by a tensioning unit, and handles for upward and downward movement along the leg.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-pressure massage device is used, then the structure is simple, but the massage intensity cannot be adjusted for different user preferences and leg sizes
Solution Approach 1:
The patent applies the dynamics principle by incorporating a tensioning unit with adjustable tension members that allow the massage balls to be dynamically repositioned along the leg ring. This enables the massage intensity to be adjusted by tightening or loosening the tensioning unit, transforming a static structure into a dynamic one that adapts to different user preferences and leg sizes while maintaining reasonable structural complexity
Solution Approach 2:
The patent applies parameter changes by modifying the positional parameter of the massage balls along the leg ring through the tensioning unit. By changing the tension parameter of the spring mechanism, the balls can be urged toward or away from the leg, thereby adjusting the massage pressure parameter to suit different users without requiring complete redesign of the device structure
2Adaptability or versatility
If massage balls are fixed on the leg ring, then the device structure is simple, but the massage coverage is limited for comprehensive muscle treatment
Solution Approach 1:
The tensioning unit enables the massage balls to be dynamically positioned at different locations along the leg ring by adjusting the tension. This dynamic positioning capability allows comprehensive coverage of different muscle groups on the leg, from upper to lower portions, while maintaining a relatively simple overall device structure through the use of a spring-based adjustment mechanism
3Adaptability or versatility
If the leg ring is made rigid for stability, then the structural integrity is good, but it cannot accommodate different leg sizes and provide comfortable pressure distribution
Solution Approach 1:
The patent applies local quality by making only the necessary portions of the leg ring flexible through the integration of the tensioning unit and massage balls, while maintaining the overall rigid structure of the leg ring for stability. The flexibility is localized to the tensioning mechanism that allows adjustment for different leg sizes, whereas the main leg ring structure remains stable and intact

AI summary
A muscle massaging assembly includes a leg ring which comprises a first half hingedly coupled to a second half such that the leg ring forms a closed loop to surround a user's leg. A plurality of balls is each integrated into the leg ring to compress against the user's leg when the leg ring is positioned around the user's leg. A tensioning unit is movably integrated into the leg ring and the tensioning unit is in communication with the plurality of balls. Each of the plurality of balls is either urged away from the leg ring or toward the leg ring when the tensioning unit is either tightened or loosened. A pair of handles is each coupled to the leg ring and each of the handles can be gripped by the user for urging the leg ring upwardly and downwardly along the user's leg.
