Solution Overview

Problem

Current vacuum furnaces for metal thermal treatment are large in size, making them non-transportable and inefficient for processing small quantities of metal, as they require extensive dimensions for cooling systems that integrate within the bell, complicating reduction in size and increasing costs.

Innovation Solution

The cooling system is relocated externally to the bell, forming a closed circulation path for a cooling fluid that circulates through a thermal exchanger, allowing for reduced bell dimensions while maintaining efficient cooling, and enabling the equipment to be mobile and easily transported.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cooling system is integrated within the bell, then the cooling function is provided, but the bell dimensions become very big and the equipment becomes non-transportable

Engineering Contradiction:
Improvecooling functionVSAvoidbell dimensions
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The cooling system is extracted from the bell structure and placed externally. The patent describes a cooling system with a heat exchanger, pump, and reservoir that operates outside the bell, connected through fluid conduits. This extraction removes the bulky cooling components from the bell, significantly reducing its dimensions while maintaining the cooling function through the external system.

Inventive Principle:
Principle #2Taking out (Extraction)

2Volume of moving object

If the bell dimensions are reduced for transportability, then the equipment becomes mobile, but the cooling system becomes inefficient and hard to realize

Engineering Contradiction:
Improvebell dimensionsVSAvoidcooling efficiency
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The patent introduces an external cooling system as an intermediary between the bell and the cooling function. The cooling system includes a heat exchanger that receives hot fluid from the bell through conduits, cools it externally, and returns the cooled fluid to the bell. This intermediary external system allows the bell to be small and transportable while maintaining efficient cooling through the dedicated external cooling infrastructure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the cooling system is integrated within the bell, then the cooling function is provided, but the equipment becomes fixed and installation costs increase

Engineering Contradiction:
Improvecooling functionVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent segments the thermal treatment equipment into separate functional modules: the bell for thermal treatment, an external cooling system with heat exchanger and pump, and a fluid circulation system connecting them. This segmentation allows each component to be manufactured, tested, and installed independently, reducing overall installation complexity and enabling the equipment to be assembled in different locations without moving the entire integrated system.

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention concerns an equipment for the thermal treatment of metal pieces. The equipment comprises : - A bell (10) provided with a receiving cavity (20) into which to be able to position one or more than one metal pieces to be thermally treated; - Heating means to raise the internal temperature of the receiving cavity (20) to a pre-established value and; - An assembly of thermal exchange (100; 200; 300) to lower the temperature reached in the receiving cavity (20) in such a way as to operate the pre-established thermal treatment on the pieces. In accordance with the invention, the assembly of thermal exchange (100; 200; 300) is arranged externally to the bell (10) in such a way as to allow a reduction of the overall dimensions of the said bell.
