Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional massage machines have a monotonous massage mode, leading to a poor massage experience for users.
Innovation Solution
A limb massage mechanism with a motor, speed reducer, rotating shaft, and eccentrically arranged treatment pieces that rotate to provide a cyclic massage through clockwise and anticlockwise motions, utilizing air bags for pressure and adjustable positioning for enhanced comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If air bags are used for arm massage, then the massage function is provided, but the massage mode is monotonous
Solution Approach 1:
The massage mechanism is segmented into multiple treatment pieces (rolling pins, kneading rollers, tapping pins) that can independently contact the arm. Each treatment piece provides a different massage mode, allowing the system to offer diverse massage functions without requiring completely separate devices for each mode.
Solution Approach 2:
The rotating shaft assembly serves multiple functions: it can rotate to provide rolling massage, the treatment pieces can be positioned at different locations to provide kneading and tapping massage, and the same mechanism works for different arm positions. This multi-functionality resolves the contradiction by providing varied massage modes through a single integrated mechanism.
2Area of stationary object
If treatment pieces are arranged on the rotating shaft, then cyclic massage is achieved, but the massage coverage is limited
Solution Approach 1:
The treatment pieces are arranged not only radially around the rotating shaft but also at different axial positions and angular positions. This three-dimensional arrangement allows multiple treatment pieces to contact different areas of the arm simultaneously, expanding the massage coverage area without significantly increasing mechanism complexity.
Solution Approach 2:
The treatment pieces are nested on the rotating shaft in a compact arrangement, with multiple pieces mounted at different positions along the shaft. This nested configuration maximizes the use of space, allowing more treatment pieces to be accommodated within a compact structure, thereby increasing coverage area without proportionally increasing overall device size or complexity.
3Adaptability or versatility
If the bracket and support housing are fixed, then the structure is stable, but the positioning flexibility is reduced
Solution Approach 1:
The bracket and support housing are designed with adjustable and detachable connections, allowing the structure to transition between fixed and adjustable states. This dynamic design enables the massage mechanism to be positioned at different locations and orientations while maintaining structural stability during operation, resolving the contradiction between stability and positioning flexibility.
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 mechanism provides a more comfortable and effective massage experience by varying the massage mode through the helical arrangement of treatment pieces and air bag placement, enhancing user satisfaction.
Implementation Method 1
The motor is initiated to provide power to the speed reducer; the speed reducer controls the rotating shaft to rotate
Implementation Method 2
the several treatment pieces are eccentrically arranged on the first rotating shaft, wherein the several treatment pieces are helically mounted on the first rotating shaft
