Solution Overview

Problem

Existing methods for reducing subcutaneous adipose tissue are often ineffective, particularly in cases where physical activity or certain treatments are not feasible, and they often fail to achieve selective fat loss in specific body areas.

Innovation Solution

A treatment device incorporating a vacuum applicator and a thermal conductor is used to selectively remove heat from subcutaneous lipid-rich cells, employing a cooling unit and a token with a microelectronic device to control and monitor the treatment process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional non-invasive treatments (topical agents, weight-loss drugs, exercise) are used, then general weight loss may be achieved, but selective fat loss in specific body areas cannot be achieved

Engineering Contradiction:

Improveselectivity of fat lossVSAvoidfeasibility of treatment

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The cooling device applies localized cooling to specific body areas through an applicator that contacts the skin at the target site. The system delivers cooling energy selectively to subcutaneous adipose tissue in the treated region while leaving other areas unaffected, enabling area-specific fat reduction rather than general weight loss.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The treatment system is divided into separate functional components including a cooling unit, control system, and applicator. The cooling unit can be selectively applied to different body areas, allowing targeted treatment of specific fat deposits while maintaining the ability to treat multiple locations with the same device.

Inventive Principle:

Principle #1Segmentation

2Productivity

If invasive procedures like liposuction are used, then significant fat removal can be achieved, but recovery time and discomfort increase

Engineering Contradiction:

Improveefficacy of fat removalVSAvoidrecovery time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system replaces mechanical surgical intervention (liposuction) with a thermal/cooling-based approach. Instead of physically removing fat through surgical incisions and suction, the device uses controlled cooling to induce apoptosis in adipocytes, allowing the body to naturally eliminate dead fat cells over time without surgical recovery.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system exploits the selective vulnerability of adipose tissue to cold temperatures. By applying controlled cooling, the device intentionally induces cellular damage (apoptosis) in fat cells, which then triggers the body's natural cleanup mechanisms to remove the dead cells, converting a potentially harmful effect into a beneficial fat-reduction outcome.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Manufacturing precision

If cooling is applied to subcutaneous adipose tissue, then selective fat cell damage is achieved, but risk of freezing non-lipid rich cells increases

Engineering Contradiction:

Improveselectivity of cell damageVSAvoiddamage to non-lipid rich cells

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The system carefully controls the temperature parameters applied to tissue, maintaining cooling temperatures above the freezing point of water (e.g., -5°C to 10°C). By adjusting the temperature to be cold enough to damage lipid-rich cells but not cold enough to freeze non-lipid cells, the system achieves selective cell damage while protecting surrounding healthy tissue.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Instead of applying heat or chemical agents that could damage multiple cell types, the system inverts the approach by using cold temperatures that selectively affect adipocytes. The inversion lies in exploiting the unique thermal sensitivity of fat cells compared to other tissue types, turning cold (typically associated with preservation) into a selective damaging agent for fat cells only.

Inventive Principle:

Principle #13The other way round (Inversion)

Function Achieved in This Case

The device effectively reduces subcutaneous lipid-rich cells by inducing apoptosis and enhancing lipolysis, achieving selective damage to fat tissue while minimizing impact on non-lipid rich cells, thus providing a non-invasive and efficient method for body contouring.

AI summary

Devices, systems and methods for removing heat from subcutaneously disposed lipid-rich cells are disclosed. In selected embodiments, suction and/or heat removal sources are coupled to an applicator. The applicator includes a flexible portion and a rigid portion. The rigid portion includes a thermally conductive plate and a frame coupling the thermally conductive plate and the flexible portion. An interior cavity of the applicator is in fluid communication with the suction source, and the frame maintains contiguous engagement between the heat removal source and the thermally conductive plate.
