Massage Chair Coordinate-Based Arm Sequencing to Reduce Session Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage chairs require long massage times to achieve desirable relaxing effects, necessitating a more efficient method to reduce stress and relieve pain.
Innovation Solution
The massage chair employs a coordinated system of massage arms and airbags that perform specific sequences of movements and pressures along defined axes to apply kneading, tapping, and pressure actions on various body areas, including the use of a coordinate system to position contact members and inflate airbags in timed durations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing massage programs are used to achieve desirable relaxing effects, then the massage effectiveness is improved, but the massage time becomes relatively long
Solution Approach 1:
The massage program is divided into multiple distinct sequences, each targeting specific body regions (shoulders, lower back, etc.) with specific massage actions. This segmentation allows the system to focus on key stress areas individually, achieving effective relaxation in shorter time by concentrating massage efforts where most needed rather than uniformly massaging the entire body
Solution Approach 2:
Different massage sequences are designed with different characteristics tailored to specific body regions. For example, the first sequence targets shoulder areas with specific contact member movements, while the second sequence targets the lower back with different movements. This local customization of massage quality for different body parts increases overall effectiveness while reducing total time needed
2Adaptability or versatility
If multiple massage actions are applied to different body regions, then the comprehensive massage coverage is improved, but the device complexity increases
Solution Approach 1:
The massage arms are designed with universal functionality to perform multiple types of massage actions (kneading, tapping, pressing, rolling) on different body regions. The same physical components execute different sequences for shoulders, lower back, and other areas, achieving comprehensive coverage without proportionally increasing device complexity through dedicated mechanisms for each region
3Measurement precision
If precise positioning of contact members is implemented using coordinate system, then the massage precision is improved, but the control complexity increases
Solution Approach 1:
A three-dimensional coordinate system (lengthwise axis, transversal axis, front-rear axis) is established to precisely define contact member positions and movement paths. This dimensional framework enables accurate positioning and repetition of massage actions at specific locations, improving massage precision while providing a systematic control approach
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 approach allows for shorter, effective massage sequences that relieve tension and pain in specific body regions, such as the neck, shoulders, and lower back, enhancing the massage experience and reducing muscular discomfort.

AI summary
Methods of driving a massage chair are described for dispensing effective massage to reduce stress and relieve pain in an effective manner. The massage chair includes a backrest, a seat, two massage arms assembled with the backrest and having at least two contact members, a plurality of bottom airbags disposed in the seat, and a plurality of lateral airbags disposed at a left and a right side of the seat. The method includes defining a coordinate reference including a lengthwise axis extending along a length of the backrest, a transversal axis extending from a left toward a right side of the backrest, and a front-rear axis extending from a front toward a rear of the backrest, and driving the massage arms to perform certain sequences of massage actions to provide relief in the neck and shoulder areas, the lower back, and thigh and hip.
