Massage Drive Speed Control for Uniform Body-Shape Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massagers fail to provide uniform massage experiences across users of varying weights and spinal lengths, leading to inconsistent massage patterns and effectiveness, particularly in demonstrations where multiple users receive different massages, and struggle to adjust massage strength accurately.
Innovation Solution
A massager controlling apparatus that includes a setting part to adjust massage mode, a control part to adjust the moving speed of a driving module based on user body shape, and a method to calculate weight and spinal length for uniform massage pattern completion time and adjustable massage strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the moving speed of the driving body is always uniform, then the control is simple, but the massage operation times cannot be adjusted according to user's weight and lower back length
Solution Approach 1:
The patent applies dynamics by transitioning from a uniform moving speed to a variable moving speed that adapts to different user body shapes. The control unit calculates appropriate moving speeds based on the user's lower back length and weight, allowing the massage device to complete massage patterns in consistent time regardless of user variations, thus resolving the contradiction between control simplicity and time adjustment capability.
2Duration of action of moving object
If additional massage is performed to unify end times, then the overall massage time is unified, but the massage pattern is practically changed and different massages are provided to users
Solution Approach 1:
The patent applies parameter changes by adjusting the moving speed parameter dynamically based on user body shape measurements. Instead of adding or removing massage operations, the system modifies the speed at which the driving body moves, allowing all users to complete the same massage pattern in the same time without altering the massage sequence or adding extra operations, thus maintaining massage consistency while achieving time uniformity.
3Ease of operation
If the user arbitrarily adjusts massage time, then the massage time is flexible, but only the massage time is changed and the entire pattern is not performed or a part is repeatedly performed
Solution Approach 1:
The patent applies feedback by using the control unit to calculate and adjust the moving speed based on user body shape measurements. The system provides automated feedback control that ensures the complete massage pattern is performed correctly for each user type, preventing incomplete or repeated patterns while still allowing time flexibility through speed adjustment. This eliminates the need for users to manually adjust time parameters.
4Ease of operation
If massage strength is gradationally specified by mechanical structure, then the massage strength is controllable, but the design and manufacturing process of the driving body becomes complicated
Solution Approach 1:
The patent applies mechanics substitution by replacing the mechanical structure-based massage strength control with a control-unit-based system. Instead of using complex mechanical mechanisms to provide gradational massage strengths, the system uses the control unit to adjust the moving speed of the driving body, which indirectly controls the massage strength. This simplifies the mechanical design while maintaining controllable massage strength through software-based speed regulation.
