Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body fat reduction methods, such as liposuction and conventional cryolipolysis, are costly, risky, time-consuming, and less efficacious, leaving patients seeking safer and more effective alternatives.
Innovation Solution
A surgical injection device and method using a chilled aqueous solution and ice slurry, comprising dextrose and sodium chloride, to induce ice phase-change lipolysis for targeted fat cell destruction without general anesthesia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cryolipolysis or liposuction is used for body fat reduction, then fat reduction effect is achieved, but patient cost, pain, discomfort, and health risks increase
Solution Approach 1:
The patent utilizes the phase transition of water from liquid to solid state (freezing) to destroy fat cells. The aqueous solution is cooled to sub-zero temperatures and injected as a slurry, where the ice crystals form and physically disrupt adipose tissue through phase change, achieving fat reduction without the need for surgical liposuction or conventional cryolipolysis devices
Solution Approach 2:
The patent replaces mechanical liposuction systems (surgical instruments, anesthesia equipment, suction devices) with a chemical/physical injection system. Instead of mechanically removing fat through suction, the invention uses injected aqueous solution that freezes and chemically/physically destroys fat cells in situ, eliminating the need for complex mechanical removal systems
2Loss of substance
If liposuction surgery is performed for body fat reduction, then significant fat removal is achieved, but procedure time and recovery time increase
Solution Approach 1:
The patent extracts and removes the unnecessary components of traditional liposuction (anesthesia, surgical incisions, mechanical suction, extended recovery) while retaining the core function of fat removal. The procedure is reduced to a simple injection of aqueous solution that automatically freezes and destroys fat cells, eliminating time-consuming surgical steps
Solution Approach 2:
The patent divides the fat reduction process into discrete, manageable steps: injection of aqueous solution, freezing phase change, fat cell destruction, and natural elimination. This segmentation allows the procedure to be completed in minutes without the need for prolonged surgical intervention or recovery periods
3Reliability
If conventional fat reduction methods are used, then fat reduction is achieved, but treatment depth and ability to reach hard-to-access areas are limited
Solution Approach 1:
The patent uses hydraulic principles by injecting aqueous solution through a syringe or injection device that delivers the freezing agent deep into subcutaneous tissue. The liquid injection mechanism allows precise delivery to hard-to-reach areas that are inaccessible to conventional cryolipolysis applicators or liposuction cannulas, enabling treatment of deeper and more remote fat deposits
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 method achieves deeper and more efficacious fat reduction with reduced risks and costs, allowing treatment of hard-to-reach areas and achieving 25-50% fat reduction in treated areas.
Implementation Method 1
injection ice phase-change lipolysis
Implementation Method 2
mixture of chilled aqueous solution and ice
Implementation Method 3
dissolved monosaccharide and dissolved salt being of sufficient concentrations such that the slurry may be super-chilled while remaining substantially free-flowing liquid solution
