Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing adipose tissue, such as liposuction and ultrasound-assisted liposuction, are invasive, risk tissue damage, and lack uniformity in fat cell destruction, while external ultrasound techniques have limitations in effectiveness and safety.
Innovation Solution
A non-invasive apparatus that applies compressive and shearing forces to adipose tissue using a hand-held device with sinusoidal plates, supplemented by motor-driven motion and optional energy sources like ultrasonic or thermal energy, to rupture and remove adipose cells without invasive procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional liposuction is used to remove adipose tissue, then fat cells can be removed effectively, but the procedure is invasive and causes trauma to the patient
Solution Approach 1:
The patent replaces the mechanical suction system of traditional liposuction with a non-invasive mechanical compression and shearing system. Two rollers with opposing rotational directions apply compressive and shearing forces directly to the adipose tissue through the skin, eliminating the need for invasive cannulas and vacuum suction while still achieving effective fat cell disruption.
Solution Approach 2:
The patent introduces rollers as an intermediary device that transmits mechanical forces through the skin to the adipose tissue. These rollers act as a mediator between the external power source and the target tissue, enabling force application without direct invasive contact and reducing trauma to nerves and blood vessels.
2Productivity
If ultrasound transducer is used to lyse adipose cells, then fat cell destruction is enhanced, but the transducer becomes hot and may damage adjacent tissues
Solution Approach 1:
The patent replaces the ultrasonic energy field with a direct mechanical force system. Instead of using high-frequency vibrations that generate heat, the invention uses controlled mechanical compression and shearing forces from rotating rollers to disrupt adipose cells, eliminating thermal effects while maintaining cell lysis effectiveness.
3Productivity
If cannula is moved through tissue region during liposuction, then adipose tissue can be removed, but nerves and blood vessels may be damaged
Solution Approach 1:
The patent uses rollers as an intermediary that distributes force over a broader area of tissue rather than concentrating it at a single invasive point. This distributed mechanical force application through the skin and subcutaneous layers reduces the risk of damaging individual nerves and blood vessels while still achieving effective adipose tissue disruption.
4Productivity
If liposuction is performed to achieve desired body shape, then fat removal is achieved, but uniformity of final shape is compromised due to irregular removal
Solution Approach 1:
The patent employs dynamically rotating rollers that can be moved across different areas of the body. The rotational motion combined with the ability to apply varying compression forces allows for more uniform and controlled disruption of adipose tissue across the treatment area, improving the uniformity of the final body contour compared to the localized, operator-dependent fat removal of traditional liposuction.
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
Minimizes trauma, achieves uniform body contouring by rupturing adipose cells through controlled mechanical forces, and can be combined with other energy types for enhanced effectiveness, reducing the risk of complications associated with traditional liposuction.
Implementation Method 1
applies a compressive force to underlying adipose cells from a location external to a patient to rupture or otherwise remove cells
Implementation Method 2
The target cells, preferably adipose cells, may be ruptured through the application of shear force
Implementation Method 3
The transducer emits ultrasonic energy, generally at frequencies of 20-30 kHz, that heats the tissue in the region until necrosis or cavitation or both occurs
Implementation Method 4
heats the tissue in the region until necrosis or cavitation or both occurs, thereby rupturing adipose cells in the region
Implementation Method 5
This may result in damage or destruction of tissues adjacent to the target region by overheating or melting

AI summary
An apparatus and method for simultaneously applying a compressive and a reciprocating force to underlying adipose cells from a location external to a patient's skin to rupture or otherwise remove the adipose cells within a subcutaneous tissue region. The adipose cells are ruptured through the mechanical application of compression and shearing forces. The patient's body then re-absorbs and expels the ruptured cells. This eliminates the need for invasive liposuction and the trauma associated with invasive liposuction. Various mechanical devices may be employed to impart the compressive and shearing forces.
