Rotatable Arm Massage Part for Adaptive Stretching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current massage devices lack the ability to provide tailored massage functions and stretching capabilities for individual users, particularly for the arms, which can vary in desired stimulation and comfort.
Innovation Solution
A massage device with a rotatable arm massage part that includes a body massage part and arm massage parts, featuring a rotation module for vertical and horizontal rotation, an arm length adjustment module, and a control unit to adjust the arm length based on the rotation amount, allowing for customizable massage and stretching functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a massage device provides fixed massage functions, then the device structure is simple, but it cannot accommodate different user preferences and stretching needs
Solution Approach 1:
The arm massage part is designed to be rotatable in multiple directions (vertical and horizontal) rather than fixed, allowing dynamic adjustment of massage orientation to accommodate different user preferences and stretching needs while maintaining a relatively simple overall structure
Solution Approach 2:
The massage device is divided into independent functional modules: a body massage part and separate arm massage parts that can rotate independently. This segmentation allows each part to be optimized for its specific function while maintaining overall structural simplicity
2Adaptability or versatility
If the arm massage part is made rotatable in multiple directions, then stretching and rehabilitation functions are improved, but the device complexity increases
Solution Approach 1:
The arm massage part incorporates rotation capabilities in both vertical and horizontal directions, transforming it from a static to a dynamic structure. This enables the device to provide stretching and rehabilitation functions by adjusting the orientation of the arm massage part according to user needs
Solution Approach 2:
The rotatable arm massage part serves multiple functions: it can provide massaging actions, stretching actions, and rehabilitation actions by simply changing its orientation. This multi-functionality reduces the need for separate dedicated mechanisms for each function
3Ease of operation
If the arm length is adjustable based on rotation amount, then user comfort and effectiveness are improved, but the control system complexity increases
Solution Approach 1:
The control unit receives feedback information about the rotation amount of the arm massage part and automatically adjusts the arm length accordingly. This feedback mechanism ensures optimal user comfort and effectiveness without requiring manual intervention
Solution Approach 2:
The system automatically adjusts the arm length based on the rotation amount without requiring user input or manual adjustment. The control unit autonomously coordinates the arm length adjustment with the rotation movement to maintain optimal positioning
