Massage Ball Assembly Tilting Frame Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massage chairs fail to provide an optimal massage suitable for the curved shape of a seated person due to the fixed rotation of massage balls, which limits their ability to conform to the user's shoulders, back, and buttocks.
Innovation Solution
A massage ball assembly with a rotatable tilting frame that allows massage balls and heating balls to move independently, adjusting to the user's curves by rotating with respect to the main frame, providing a more personalized massage experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If massage balls are fixed to the main frame and rotate only, then the structure is simple and easy to manufacture, but the massage quality is insufficient for curved body parts
Solution Approach 1:
The massage ball assembly is divided into multiple independent components: the main frame, tilting frames, massage balls, and heating balls. Each component can move independently, allowing the system to adapt to complex body curves while maintaining manufacturing simplicity through modular design.
Solution Approach 2:
The tilting frames are designed to be rotatable relative to the main frame, transforming the static structure into a dynamic one. This allows the massage balls to adjust their position and angle automatically to conform to the curved surfaces of shoulders, back, and buttocks during massage operations.
2Device complexity
If massage balls move only up, down, left, and right with the massage bundle, then the device complexity is low, but the massage effectiveness on curved surfaces is limited
Solution Approach 1:
The tilting frames add a rotational degree of freedom around the longitudinal axis of the main frame. This new dimension of movement allows the massage balls to orient themselves properly against curved body surfaces, significantly improving massage effectiveness without substantially increasing device complexity.
3Device complexity
If a single main frame structure is used, then the device structure is simple, but it cannot provide both massage and heating functions independently
Solution Approach 1:
The heating balls are integrated with the massage ball assembly on the tilting frames, combining massage and heating functions in a unified structure. Both functions operate independently through the same mechanical movement system, providing functional versatility without requiring separate frame structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The rotatable tilting frames enable a more effective massage by conforming to the user's body shape, improving the massage quality and allowing independent heating and massage sensations, addressing the limitations of conventional massage chairs.
Implementation Method 1
heating balls (622, 632) each mounted on the one or more tilting frames (620, 630)
