Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sound stimulation devices do not effectively improve muscle strength, as demonstrated by the lack of significant difference in contractile force between control and sound stimulus groups in mice experiments.
Innovation Solution
A muscle strength improvement device that generates sound stimuli with varying frequencies over time, specifically with frequencies of 140 Hz or less, and a difference between maximum and minimum frequencies of 60 Hz or less, to enhance muscle strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a constant frequency sound stimulus is applied, then the device structure is simple, but muscle strength improvement is not achieved
Solution Approach 1:
The patent applies dynamics by making the sound stimulus frequency variable rather than constant. The frequency changes over time according to a predetermined pattern, transforming the static sound stimulus into a dynamic one that effectively improves muscle strength while managing device complexity through automated control.
Solution Approach 2:
The patent changes the frequency parameter of the sound stimulus over time. By varying the frequency according to a predetermined pattern rather than maintaining a constant frequency, the device achieves muscle strength improvement while the complexity is managed through programmed control sequences.
2Adaptability or versatility
If sound stimulus frequency varies widely, then more muscle groups can be targeted, but the stimulus becomes less effective for specific muscle strength improvement
Solution Approach 1:
The patent applies periodic action by varying the sound stimulus frequency in a structured, periodic manner. The frequency changes follow a predetermined pattern that systematically targets different muscle groups while maintaining effectiveness for strength improvement, balancing versatility with targeted impact.
