Solution Overview

Problem

Existing cosmetic treatments using electrical muscle stimulation (EMS) technologies often lead to temporary muscle contraction and eventual depletion of ATP, resulting in lax muscles and accelerated aging due to high amperage usage.

Innovation Solution

The development of a handheld device that delivers microcurrents with amperage at or below 400 µA, combined with kinesiological sculpting techniques, to stimulate mitochondria and increase ATP production without causing muscle contraction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If high amperage electrical muscle stimulation (EMS) is used to achieve muscle contraction, then muscle tonicity is temporarily improved, but ATP is depleted and muscles become lax leading to accelerated aging

Engineering Contradiction:
Improvemuscle tonicityVSAvoidATP depletion
Core Design Contradiction:
StrengthVSLoss of energy

Solution Approach 1:

The patent changes the key parameter from high amperage (EMS) to low amperage (microcurrent ≤400 µA), fundamentally altering the mechanism from muscle contraction to mitochondrial stimulation. This parameter change resolves the contradiction by achieving muscle tonicity improvement through ATP production enhancement rather than ATP-consuming contraction cycles

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mechanical/electrical contraction mechanism with a biochemical mitochondrial stimulation mechanism. Instead of using electrical currents to directly contract muscles (EMS), the system uses microcurrents to stimulate mitochondria to produce ATP, which then naturally enhances muscle tonicity without the harmful contraction-depletion cycle

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Duration of action of stationary object

If microcurrents at or below 400 µA are used to stimulate mitochondria and increase ATP, then muscle tonicity and endurance are enhanced without contraction, but the current intensity is significantly reduced compared to EMS

Engineering Contradiction:
Improvemuscle enduranceVSAvoidcurrent intensity
Core Design Contradiction:
Duration of action of stationary objectVSPower

Solution Approach 1:

The patent changes the power parameter from high intensity (500-5000 µA EMS) to low intensity (≤400 µA microcurrent), and simultaneously changes the mechanism of action from direct muscle stimulation to mitochondrial ATP production. This resolves the contradiction by achieving enhanced muscle endurance through increased ATP availability rather than through high-power contraction stimulation

Inventive Principle:
Principle #35Parameter changes

3Strength

If repeated EMS treatments are applied to maintain muscle tonicity, then temporary muscle strengthening occurs, but continuous ATP depletion accelerates the aging process

Engineering Contradiction:
Improvemuscle tonicityVSAvoidaging acceleration
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful ATP depletion effect of EMS into a beneficial ATP production enhancement. By using microcurrents to stimulate mitochondria, the system generates excess ATP (up to 500% more) that not only maintains muscle tonicity but also accelerates collagen and elastin synthesis, thereby combating aging rather than accelerating it

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

Solution Approach 2:

The patent changes the current parameter from high amperage EMS to low amperage microcurrent, fundamentally altering the biological effect from catabolic (ATP depletion) to anabolic (ATP production and tissue synthesis). This resolves the contradiction by achieving muscle tonicity improvement through a mechanism that simultaneously prevents aging

Inventive Principle:
Principle #35Parameter changes

AI summary

A system advantageously includes a handheld device with a body with two pairs of electrodes mounted or carried by respective arms extending from the handheld body, where at least one pair of arms is movable (e.g., pivotal, rotatable) with respect the body and hence with respect to the other pair of arms. The moveable arms can be biased toward an un-rotated position or orientation, applying a tension to bodily tissue via the moveable arms when rotated out of the un-rotated position or orientation. The system optionally includes a circuit integral to the handheld device, or integral to a console to which the handheld device is coupled, the apparatus operable to deliver microcurrent signals via two separate channels and via interferential signals between the two separate channels, to facilitate kinesiology facial sculpting application in conjunction with the delivery of microcurrent signals, which can be employed in cosmetic applications.
