Solution Overview

Problem

Existing cryolipolysis devices for fat reduction are complex to manufacture and require numerous electronic and cooling elements, making them costly and difficult to assemble, with safety systems adding complexity and the need for qualified labor, and they struggle to adapt to complex anatomical areas.

Innovation Solution

A non-invasive cold fat reduction system with a central unit that cools a fluid to below 0°C, which is transported to an applicator without active cooling elements, simplifying manufacturing and allowing for better adaptation to body morphology by eliminating the need for Peltier effect cells and electronic components within the applicator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If Peltier cells and electronic cooling elements are integrated into the applicator, then active cooling capability is achieved, but device complexity and manufacturing cost increase significantly

Engineering Contradiction:
Improvecooling capabilityVSAvoidapplicator structure
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The active cooling elements (Peltier cells, electronic boards, temperature sensors) are extracted from the applicator and relocated to a separate central unit. The applicator is reduced to passive components (cavity, suction system, wall), eliminating the need for integrated electronic cooling while maintaining the fat freezing capability through centralized cooling fluid circulation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A cooling fluid serves as an intermediary medium between the central unit's cooling device and the applicator's cavity wall. The fluid absorbs heat from the cavity wall, enabling passive cooling of the fat deposit without requiring direct integration of active cooling elements in the applicator.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If multiple temperature sensors and electronic components are integrated into the applicator for safety, then patient safety is improved, but applicator size and assembly complexity increase

Engineering Contradiction:
Improvesafety systemVSAvoidapplicator components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Temperature sensors and electronic safety components are extracted from the applicator and relocated to the central unit. The safety monitoring function is maintained through centralized sensor placement and electronic control, while the applicator structure is simplified to contain only mechanical and passive thermal components.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If numerous components are assembled in the applicator, then functional capabilities are achieved, but assembly time and skilled labor requirements increase

Engineering Contradiction:
Improvetreatment functionalityVSAvoidassembly speed
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system is segmented into two distinct functional modules: a centralized unit containing all complex electronic components, cooling devices, and control systems; and a simplified applicator containing only the treatment cavity, suction system, and passive thermal conduction elements. This segmentation allows the applicator to be manufactured and assembled rapidly without requiring skilled assembly of multiple electronic components.

Inventive Principle:
Principle #1Segmentation

4Temperature

If the applicator contains active cooling elements, then precise temperature control is achieved, but manufacturing cost and production time increase

Engineering Contradiction:

Core Design Contradiction:
TemperatureVSEase of manufacture

Solution Approach 1:

Active cooling elements are extracted from the applicator and consolidated in a centralized unit. The applicator is manufactured as a simple passive structure using conventional fabrication methods, while precise temperature control is achieved through the centralized cooling system that circulates refrigerated fluid through the applicator wall.

Inventive Principle:
Principle #2Taking out (Extraction)
