Solution Overview

Problem

Current weight loss solutions are not universally effective, and there is a need for a safe and easy method to alter body mass composition to address obesity and osteoporosis, including reducing body fat, increasing lean muscle mass, and enhancing bone mineral density.

Innovation Solution

Galvanic vestibular stimulation (GVS) is applied via electrodes on the scalp to stimulate the otolith organs, activating the vestibular system, which modulates sympathetic nervous system activity, affecting brain structures and hormone release to achieve changes in body mass composition, including reducing body fat, increasing lean muscle mass, and enhancing bone mineral density.

1Reliability

If conventional weight loss methods (diet, exercise, medications, surgery) are used, then weight loss may be achieved, but these methods are not universally effective and have significant complexity and side effects

Engineering Contradiction:

Improveeffectiveness of weight lossVSAvoidcomplexity of weight loss solution

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical and behavioral weight loss systems (diet, exercise regimes) with a simplified electrical stimulation system. Galvanic vestibular stimulation uses electrical currents applied through ear electrodes to stimulate the vestibular system, substituting the need for complex lifestyle changes and medications with a straightforward electrical intervention that activates natural physiological weight loss pathways.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The vestibular system serves as an intermediary between the applied electrical stimulation and the target physiological processes. The galvanic current stimulates vestibular nuclei, which then activate downstream pathways including the hypothalamus and autonomic nervous system, ultimately regulating appetite, metabolism, and body composition without requiring direct intervention in these complex systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If pharmacological treatments are used to treat osteoporosis and obesity, then bone mineral density and body composition may improve, but drug side effects and treatment complexity increase

Engineering Contradiction:

Improvebone mineral density improvementVSAvoiddrug side effects

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the typically harmful effect of gravity (which accelerates bone loss in aging and weight loss scenarios) into a beneficial stimulus. By using galvanic vestibular stimulation to simulate gravitational and accelerative forces on the vestibular system, the method triggers physiological responses that increase bone formation and improve body composition, effectively using a simulated mechanical stress to produce anabolic effects without actual mechanical loading.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent replaces pharmacological interventions with a physical stimulation approach. Instead of using drugs to chemically alter bone metabolism and body composition, the system uses electrical stimulation of the vestibular system to naturally trigger physiological pathways that improve bone mineral density and body composition, eliminating drug side effects while achieving similar or superior outcomes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If centrifugation is used to simulate hypergravity, then body fat reduction occurs, but the equipment complexity and accessibility are severely limited

Engineering Contradiction:

Improvebody fat reductionVSAvoidcentrifugation equipment

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a simplified copy of the hypergravity effect without requiring actual centrifugal forces. Instead of subjecting patients to physical centrifugation at high G-forces, the system uses galvanic vestibular stimulation to copy and simulate the vestibular system's response to hypergravity and acceleration, triggering the same physiological pathways for fat metabolism and body composition changes through electrical activation of vestibular nuclei.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The vestibular system acts as an intermediary that translates the simplified electrical stimulus into the complex physiological response normally requiring hypergravity exposure. The galvanic current stimulates vestibular receptors, which then activate central nervous system pathways including the hypothalamus and autonomic nervous system, producing fat metabolism changes and body composition improvements that would otherwise require complex centrifugation equipment to achieve.

Principle #24Intermediary (Mediator)

AI summary

Method and system for altering body mass composition in a human subject repeatedly apply galvanic vestibular stimulation (GVS) to the subject's scalp at a location corresponding to each of the subject's left and right vestibular systems. The methods may be used to treat obesity-related diseases such as diabetes, hypertension, type 2 diabetes mellitus and osteoporosis.
