Massage Unit Movable Arm Adapts to User Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage machines lack the ability to provide a flexible and customizable massage experience that adapts to different physical constitutions and muscle conditions, as they often rely on fixed mechanisms that do not effectively adjust to varying user needs.
Innovation Solution
The massage machine incorporates a treatment member with a movable arm system supported by a drive shaft and biasing means, including elastic members, which allows the treatment member to approach and separate from the user's body based on predetermined strength, enabling a customizable kneading massage regardless of physical constitution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mechanism is used for massage treatment, then the structure is simple and reliable, but the adaptability to different physical constitutions and muscle conditions is poor
Solution Approach 1:
The patent applies the dynamics principle by making the treatment member movable relative to the arm through the movable portion, allowing the treatment member to dynamically adjust its position and pressure based on user feedback. The arm can move toward or away from the treatment target site in response to detected muscle conditions, transforming a static structure into a dynamic adaptive system.
Solution Approach 2:
The patent implements feedback by using a detection device that monitors muscle conditions and feeds this information back to control the movement of the treatment member. The system continuously detects user response and adjusts the massage pressure and position accordingly, creating a closed-loop control system that adapts to individual user needs.
2Adaptability or versatility
If the treatment member maintains constant pressure, then the structure is simple, but the comfort and effectiveness for users with different muscle conditions is reduced
Solution Approach 1:
The patent makes the pressure dynamic by allowing the treatment member to move toward or away from the treatment target site based on detected muscle conditions. The movable portion enables continuous pressure adjustment, transforming constant pressure into variable pressure that adapts to user needs in real-time.
Solution Approach 2:
The patent changes the pressure parameter dynamically by adjusting the position of the treatment member relative to the treatment target site. The system modifies pressure levels based on feedback from the detection device, allowing pressure to vary according to muscle conditions rather than remaining fixed.
3Adaptability or versatility
If the treatment member is firmly fixed to the arm, then the structural reliability is high, but the ability to provide flexible and customizable massage is limited
Solution Approach 1:
The patent introduces a movable portion that allows relative movement between the arm and treatment member while maintaining their connection. This dynamic connection enables the treatment member to move independently in response to user feedback, providing flexibility while maintaining structural integrity through the controlled movable joint.
4Productivity
If no pressure adjustment mechanism is provided, then the device complexity is low, but the effectiveness for different body types is reduced
Solution Approach 1:
The patent uses the movable portion to enable dynamic pressure adjustment, allowing the treatment member to move toward or away from the treatment target site based on detected muscle conditions. This dynamic adjustment mechanism improves massage effectiveness for different body types while keeping the structural complexity relatively low.
Solution Approach 2:
The patent implements a feedback-based pressure adjustment system where the detection device monitors muscle conditions and controls the movement of the treatment member accordingly. This feedback mechanism enables automatic pressure optimization for different user needs without requiring complex manual adjustment systems.
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
This design allows for a more effective and comfortable massage experience by adjusting the pressure and movement of the treatment member in response to user-specific conditions, simulating a hand-massage-like experience while accommodating different body types.
Implementation Method 1
The elastic member may pull a base portion on a side opposite to the treatment member side of the second arm

AI summary
A massage unit includes a treatment member; an arm that supports the treatment member; a drive shaft that supports the arm and causes the treatment member to approach and be separated with respect to a treatment target site; a movable portion that causes the treatment member to be operable in a direction of being separated from the treatment target site when the treatment member comes into contact with the treatment target site by a force equal to or greater than predetermined strength; and biasing means for biasing the treatment member in an approaching direction.
