Solution Overview

Problem

Current methods for treating hyperhidrosis, wrinkles, bromohidrosis, chromohidrosis, acne, cellulite, hair growth, varicose veins, and other skin issues are either invasive, cause adverse side effects, or require repeated applications, lacking in effectiveness and convenience.

Innovation Solution

Non-invasive delivery of microwave therapy using antennas and a microwave generator to target specific tissues, achieving thermal alteration or ablation with minimal damage to superficial tissues through controlled energy delivery and cooling mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If invasive procedures are used to treat deep tissue conditions, then treatment effectiveness is improved, but patient comfort and recovery time worsen

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidinvasive procedures

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces invasive mechanical procedures with non-invasive microwave energy delivery. The microwave generator transmits electromagnetic energy through the skin to heat and treat deep tissue targets, eliminating the need for surgical incisions, needles, or other invasive instruments while achieving comparable or superior treatment effectiveness.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces microwave energy as an intermediary medium to deliver thermal treatment to deep tissues. Instead of directly invading the target tissue with mechanical instruments, the microwave energy penetrates through intermediate tissues (skin, fat, muscle) to reach and treat the deep tissue target, providing a non-invasive pathway for effective treatment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Temperature

If high energy is delivered to achieve deep tissue treatment, then treatment depth is improved, but damage to superficial tissues worsens

Engineering Contradiction:

Improvetreatment depthVSAvoiddamage to superficial tissues

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by selectively concentrating microwave energy at specific depth levels. Through control of microwave parameters (frequency, power, pulse duration) and positioning of the applicator, the system delivers concentrated thermal energy to the target depth while dissipating less energy in superficial tissues, achieving deep treatment without excessive surface damage.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent employs periodic or pulsed microwave delivery to achieve deep tissue treatment. By delivering energy in controlled pulses with specific duty cycles, the system allows heat to conduct to deep tissues during the pulse while providing cooling periods that prevent superficial tissue damage, enabling progressive deep heating without surface burns.

Inventive Principle:

Principle #19Periodic action

3Reliability

If repeated applications are used to achieve cumulative effect, then treatment effectiveness is improved, but treatment time and convenience worsen

Engineering Contradiction:

Improvecumulative treatment effectVSAvoidtreatment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent enables continuity of useful action by delivering microwave energy continuously or in extended pulsed sequences to achieve cumulative thermal effects in a single treatment session. This continuous energy delivery allows deep tissues to accumulate sufficient heat for effective treatment without requiring multiple separate sessions, reducing total treatment time while maintaining effectiveness.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

Methods, apparatuses and systems are provided for non-invasive delivery of microwave therapy. Microwave energy may be applied to epidermal, dermal and subdermal tissue of a patient to achieve various therapeutic and/or aesthetic results. In one embodiment, the microwave energy is applied to a target tissue via an energy delivery applicator connected to an energy generator. The energy delivery applicator may comprise one or more antennas, including monopole, dipole, slot and/or waveguide antennas (among others) that are used to direct the microwave energy to the target tissue. The energy delivery applicator may also comprise a cooling element for avoiding thermal destruction to non-target tissue and/or a suction device to localize thermal treatment at specific portions of a skin fold.
