Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current massage chairs have limitations in accurately applying stimuli to desired areas due to fixed positions of stimulus devices, leading to mechanical design constraints and increased costs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If stimulus devices are disposed at fixed positions, then the structure is simple and manufacturing cost is low, but the accuracy of applying stimulus to desired parts is poor
Solution Approach 1:
The stimulus device is divided into multiple vibration devices arranged in an array. By segmenting the single stimulus device into multiple units, the system can generate stimuli at various points between the devices without moving the devices themselves, thus improving accuracy while maintaining structural simplicity
Solution Approach 2:
The patent uses the space between vibration devices as an intermediary region where stimuli can be generated. Instead of moving the physical stimulus device to reach different locations, the system uses the intermediate spaces between fixed vibration devices as effective stimulus points through coordinated vibration
2Measurement precision
If stimulus devices are moved to reach desired parts, then the accuracy of stimulus application is improved, but mechanical design complexity and manufacturing cost increase
Solution Approach 1:
By segmenting the stimulus function across multiple fixed vibration devices, the system achieves movable stimulus coverage without actual device movement. This segmentation allows any point in the array to serve as a stimulus point through coordinated vibration of appropriate devices, avoiding complex mechanical movement mechanisms
Solution Approach 2:
The patent replaces mechanical movement of the stimulus device with a control-based system. Instead of physically moving the stimulus device to different locations, the system uses electronic control to activate different vibration devices and adjust their vibration characteristics, substituting mechanical motion with electrical control
3Ease of operation
If vibration intensity is changed to move stimulus point, then the stimulus point can be smoothly moved, but the control complexity increases
Solution Approach 1:
The system changes the vibration parameters (intensity, frequency) of the vibration devices to control the perceived stimulus point location. By adjusting these parameters dynamically, the stimulus point can be smoothly moved across the array without physical device movement, achieving smooth control through parameter modulation
