Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If combustion devices are used to generate heat for fragrance diffusion, then fragrance diffusion function is achieved, but safety risks increase due to heat generation from burning fuel

Engineering Contradiction:

ImprovesafetyVSAvoidheat generation from burning fuel

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the combustion-based thermal system with an electric heating system. The electric heating plate (33) connected to a power source (22) provides heat for fragrance diffusion without combustion, eliminating the safety risks associated with burning fuel while maintaining the fragrance diffusion function.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an electric heating plate as an intermediary heat generation device between the power source and the fragrance holder. This intermediary component transfers heat to the fragrance material without requiring direct combustion, thereby reducing harmful heat generation while maintaining effective fragrance diffusion.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If combustion devices are used for fragrance diffusion, then fragrance emission function is achieved, but device structure becomes complicated

Engineering Contradiction:

Improvefragrance emission functionVSAvoidstructure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the complex combustion system (burner, fuel storage, ignition mechanisms) from the device structure. By taking out these unnecessary components and retaining only the essential electric heating elements and fragrance holder, the device achieves fragrance emission function with a simplified structure.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The electric heating plate serves multiple functions: it heats the fragrance material for diffusion, provides a stable heat source without combustion complexity, and integrates directly with the power source. This multi-functional component replaces the entire combustion system, simplifying the overall device structure while maintaining fragrance emission capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If electric heating plate is used instead of combustion, then safety is improved, but heating efficiency may be reduced

Engineering Contradiction:

ImprovesafetyVSAvoidheating efficiency

Core Design Contradiction:

ReliabilityVSTemperature

Solution Approach 1:

The patent applies local quality by concentrating heating at the specific location where the fragrance holder contacts the electric heating plate. The heating action is localized to the interface between the heating plate and fragrance material, ensuring efficient heat transfer exactly where needed for fragrance diffusion, while the rest of the device remains safe and simple.

Inventive Principle:

Principle #3Local quality
