Solution Overview

Problem

Conventional furnace systems face challenges in achieving uniform temperature distribution, are prone to scaling, and are expensive due to complex designs and individualized manufacturing, leading to inefficiencies and increased costs.

Innovation Solution

A surface pore burner integrated directly with a double fan wheel inside the furnace chamber, eliminating the need for external pipes and allowing for rapid and even heat distribution, reducing thermal radiation and scaling issues, and enabling cost-effective, standardized production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional burners with pipes are used to heat the furnace chamber, then heating function is provided, but uniform temperature distribution cannot be achieved and scaling occurs on the pipes

Engineering Contradiction:
Improvetemperature distribution uniformityVSAvoidpipe scaling and contamination
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The patent removes the conventional pipe structure from the furnace chamber and replaces it with a porous burner plate that distributes hot gases directly through its surface. This extraction of the pipe function eliminates the scaling problem while maintaining the heating function, as the porous plate allows direct contact with hot gases without forming a protective oxide layer.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs a porous burner plate that distributes hot gases uniformly through its porous structure. The porous material allows hot gases to pass through and distribute evenly across the furnace chamber, achieving uniform temperature distribution while avoiding the scaling issues of conventional solid pipes. The porous structure prevents direct contact between the heating element and the hot medium, eliminating scaling.

Inventive Principle:
Principle #31Porous materials

2Temperature

If multiple pipes are distributed in the furnace chamber to achieve uniform temperature, then temperature distribution improves, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvetemperature distribution uniformityVSAvoidnumber and distribution of pipes
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent merges the function of multiple distributed pipes into a single porous burner plate. Instead of requiring multiple separate pipe structures, the porous plate integrates the gas distribution function across its entire surface, achieving uniform temperature distribution with one unified component rather than multiple complex pipe arrangements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The porous burner plate serves multiple functions simultaneously: it acts as the heating element, the gas distribution system, and the temperature control mechanism. This multi-functionality replaces the need for multiple specialized pipe components, simplifying the overall device structure while maintaining uniform temperature distribution capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If pipes are shielded to reduce radiant heat, then thermal radiation is reduced, but accessibility for servicing becomes difficult

Engineering Contradiction:
Improvethermal radiationVSAvoidpipe accessibility
Core Design Contradiction:
Object-affected harmful factorsVSEase of repair

Solution Approach 1:

The patent removes the pipe structure that requires shielding and servicing entirely, replacing it with a porous burner plate that is inherently resistant to thermal radiation and scaling. This extraction eliminates the need for shielding components and maintains easy accessibility for maintenance, as the porous plate can be easily accessed and serviced without requiring removal of shielding structures.

Inventive Principle:
Principle #2Taking out (Extraction)

4Power

If conventional burners are used, then heating function is provided, but frequent pipe replacement is required due to scaling

Engineering Contradiction:
Improveheating functionVSAvoidpipe service life
Core Design Contradiction:
PowerVSDuration of action of stationary object

Solution Approach 1:

The porous burner plate prevents scaling by allowing hot gases to pass through its porous structure without direct contact with the material surface. This prevents the formation of oxide layers that would require frequent replacement, extending the service life of the heating component while maintaining effective heating function.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The patent converts the potentially harmful effect of hot gases contacting the heating element (which causes scaling) into a beneficial distribution mechanism. The porous structure allows the hot gases to pass through and distribute heat uniformly, transforming what would be a scaling problem into an effective heat distribution solution that extends component life.

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