Solution Overview

Problem

Existing methods for removing excess body fat, such as liposuction and non-invasive treatments, are either invasive, painful, unpredictable, or ineffective, especially for selective fat reduction and in cases where physical activity or certain medications are not feasible.

Innovation Solution

A treatment device that includes an actuator providing mechanical energy, such as vibration, pneumatic pressure, or massage, combined with a treatment unit that uses cooling technologies to selectively affect subcutaneous lipid-rich cells while minimizing impact on non-lipid-rich cells.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If liposuction is used to selectively remove adipose tissue, then fat removal effectiveness is improved, but invasiveness and recovery time increase

Engineering Contradiction:
Improvefat removal effectivenessVSAvoidinvasiveness and recovery time
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical suction system of liposuction with a thermal field system. Treatment devices apply controlled thermal energy (heating or cooling) to the subcutaneous tissue to selectively affect adipose tissue, eliminating the need for mechanical insertion and suction operations.

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

Solution Approach 2:

The patent introduces thermal energy as an intermediary substance to transfer selective effects to adipose tissue. By controlling temperature parameters, thermal energy acts as a mediator that can selectively target lipid-rich cells while sparing surrounding tissues, avoiding direct mechanical contact.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If heating is applied to subcutaneous fat to destroy fat cells, then fat removal effectiveness is improved, but thermal damage to adjacent tissue increases

Engineering Contradiction:
Improvefat cell destruction effectivenessVSAvoidthermal damage to adjacent tissue
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by creating spatially differentiated thermal fields. Treatment devices are designed to concentrate thermal energy specifically within the subcutaneous adipose layer while maintaining lower temperatures in adjacent tissues. This is achieved through controlled heating zones, layered treatment approaches, and selective thermal targeting.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs periodic thermal action through alternating heating and cooling cycles. Treatment protocols involve repeated applications of thermal energy followed by cooling periods, allowing heat dissipation from non-target tissues while maintaining cumulative therapeutic effect on adipose tissue.

Inventive Principle:
Principle #19Periodic action

3Object-affected harmful factors

If conventional non-invasive treatments like topical agents or exercise are used, then safety is improved, but fat loss effectiveness in selective areas decreases

Engineering Contradiction:
Improvesafety and side effectsVSAvoidselective fat loss effectiveness
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent implements local quality through spatially targeted treatment zones. Treatment devices can be positioned and controlled to deliver thermal energy to specific anatomical regions, enabling selective fat reduction in targeted areas while leaving other body regions unaffected. This overcomes the systemic nature of conventional approaches.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent utilizes parameter changes by adjusting temperature, treatment duration, and energy delivery parameters to achieve selective fat cell effects. By optimizing these parameters, the treatment can induce controlled thermal effects on adipose tissue that differ from surrounding tissues, enabling selective reduction without systemic side effects.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If cooling is applied to subcutaneous adipocytes to selectively affect them, then selectivity is improved, but treatment time and discomfort increase

Engineering Contradiction:
Improveselectivity for lipid-rich cellsVSAvoidtreatment time and patient discomfort
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent employs periodic cooling action through alternating cooling and warm-up cycles. Treatment protocols involve repeated applications of cooling followed by brief warm periods, allowing heat redistribution and reducing cumulative discomfort while maintaining selective effect on adipose tissue over time.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent utilizes parameter changes by optimizing cooling temperature, treatment duration, and cycle frequency. By adjusting these parameters, the treatment achieves effective cooling of adipose tissue while minimizing patient discomfort and total treatment time through efficient thermal management.

Inventive Principle:
Principle #35Parameter changes

AI summary

A treatment device for removing heat from subcutaneous lipid-rich cells of a subject having an actuator that provides mechanical energy to the tissue. The mechanical energy provided may include a vibratory component that can range between low and ultra-high frequencies, and such energy may include various combinations of two or more frequencies tailored to produce the desired effect on the subcutaneous tissue. Disruption of adipose tissue cooled by an external treatment device may be enhanced by applying mechanical energy to cooled tissue. Furthermore, such mechanical energy may impart a vibratory effect, a massage effect, a pulsatile effect, or combinations thereof on the tissue.
