Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liposuction methods face significant side effects such as inflammation, pain, and risk of infection due to invasive procedures, necessitating a safer, more effective method for body contouring with minimal invasiveness.
Innovation Solution
A lipolysis composition injection apparatus featuring a pump and nozzle-type needles that periodically jet a high-pressure lipolysis composition into the subcutaneous fat layer, applying oscillation to maximize fat removal while minimizing adverse effects like skin depression and bruising, using a combination of lipolytic compounds, accelerators, and local anesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional liposuction methods are used, then fat removal effectiveness is improved, but side effects such as inflammation, pain, and risk of infection increase
Solution Approach 1:
The patent replaces traditional mechanical liposuction (physical suction and trauma) with a chemical system using lipolysis composition that enzymatically breaks down fat. The nozzle-type needle delivers the composition at high pressure (50-1000 psi) to dissolve fat chemically rather than mechanically removing it, thereby achieving fat removal effectiveness while minimizing trauma-induced side effects like inflammation and infection risk
Solution Approach 2:
The patent changes the physical parameters of fat removal from mechanical force and suction to chemical dissolution through controlled high-pressure injection. By adjusting injection pressure (50-1000 psi), oscillation frequency (10-1000 Hz), and composition delivery rate (300 ml/min), the system achieves effective fat breakdown while maintaining minimal invasiveness and reducing harmful side effects
2Productivity
If high concentration of lipolysis composition is injected, then lipolysis effect is improved, but adverse effects such as skin depression, skin deflection, and wrinkling increase
Solution Approach 1:
The patent employs periodic oscillation (10-1000 Hz) of the nozzle-type needle during injection, delivering lipolysis composition in controlled pulses rather than continuous flow. This periodic action allows the fat tissue to gradually break down and dissipate the composition, preventing excessive localized concentration that would cause skin depression, deflection, or wrinkling while maintaining effective lipolysis
Solution Approach 2:
The patent uses a dynamic injection system where the nozzle oscillates at varying frequencies (10-1000 Hz) and pressures (50-1000 psi) to adaptively deliver the lipolysis composition. This dynamic approach ensures even distribution of the composition throughout the fat layer, preventing localized over-concentration that would lead to skin deformation while maximizing lipolysis effectiveness
3Object-affected harmful factors
If anesthetic is added to injection, then pain during procedure is reduced, but postoperative pain, nerve palsy, local necrosis, and risk of infection increase
Solution Approach 1:
The patent extracts and removes the anesthetic component from the injection system entirely, relying instead on the lipolysis composition itself and the mechanical oscillation of the nozzle to minimize procedure pain. By eliminating anesthetic additives, the system avoids all postoperative complications associated with anesthetics (nerve palsy, local necrosis, infection risk) while maintaining patient comfort through the gentle oscillating injection mechanism
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
The apparatus effectively injects the lipolysis composition between skin and subcutaneous layers, reducing pain and adverse effects, achieving stable and efficient fat removal with increased accuracy and minimizing patient discomfort.
Implementation Method 1
The lipolysis composition may be jetted at a high pressure into a subcutaneous fat layer through the nozzle-type needle
Implementation Method 2
An oscillation may be applied to the subcutaneous fat layer through the periodical high-pressure jet. The oscillation may be a repetitive oscillation of 10 hertz (Hz) to 1000 Hz
Implementation Method 3
The high-pressure jet may be performed at a pressure of 50 pounds per square inch (psi) to 1000 psi
Implementation Method 4
The lipolysis composition may be supplied at a volume of 300 milliliters per minute (ml/min)
