Foot Electrical Stimulation Massager with Localized Current Loop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foot electrical stimulation massagers pose safety hazards and have poor physical therapy effects due to the need for electrical current to pass through the human torso, which can lead to electrolysis, electrophoresis, and electroosmosis, potentially damaging organs and causing severe health issues.
Innovation Solution
The design of a foot electrical stimulation massager with two sub-conductive regions on the same sole, allowing a current loop to be formed without passing through the torso, ensuring safer and more effective electrical stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional foot electrical stimulation massager applies electrical stimulation to both feet simultaneously with current passing through the torso, then electrical stimulation massage can be performed on both feet, but safety hazards increase and physical therapy effect deteriorates
Solution Approach 1:
The patent divides the conductive region into two separate sub-conductive regions (first and second sub-conductive regions) on the same sole. This segmentation allows the current to flow locally within one foot rather than passing through the torso to the other foot, eliminating safety hazards while maintaining electrical stimulation functionality.
Solution Approach 2:
The patent introduces a conductive gel or conductive fabric as an intermediary medium between the conductive region and the sole. This intermediary ensures good electrical contact and current transmission within the local foot area, enabling effective electrical stimulation without requiring current to pass through the entire body.
2Reliability
If electrical current passes through the human torso from one foot to the other, then complete circuit is formed, but electrolysis, electrophoresis, and electroosmosis occur causing potential organ damage
Solution Approach 1:
The patent extracts the harmful pathway of current passing through the torso by confining the current loop to local sub-conductive regions on the same sole. This removes the source of electrolysis, electrophoresis, and electroosmosis effects while maintaining a complete local circuit for safe electrical stimulation.
Solution Approach 2:
The patent converts the potential harmful effect of current passing through the body into a beneficial localised stimulation by restricting current flow to specific sub-conductive regions on the sole. This transforms a dangerous full-body current path into a safe, targeted therapeutic application.
3Adaptability or versatility
If current is transmitted through the torso to achieve bilateral foot stimulation, then both feet receive stimulation, but the current path causes poor physical therapy effect
Solution Approach 1:
The patent provides separate first and second sub-conductive regions that can independently stimulate each foot, achieving bilateral stimulation capability. Each sub-conductive region forms its own local circuit, ensuring reliable physical therapy effect for each foot without compromising the other.
Solution Approach 2:
The conductive sole with multiple sub-conductive regions provides universal applicability for stimulating different feet independently or simultaneously, maintaining effective physical therapy for each foot while offering flexible usage options for bilateral or unilateral stimulation.
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 enhances safety by eliminating the risk of current passing through the torso and improves the electrical stimulation effect by focusing the current directly on the sole, providing better muscle relaxation and pain relief.
Implementation Method 1
the first conductive region is configured to receive a current input by the positive electrode of the power source and transmit the current to the second conductive region via the sole
Implementation Method 2
The massage for the foot to stimulate the acupoints on the foot can promote the blood circulation of the body, accelerate metabolism
