Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a ceramic rod is used as the liquid conducting body, then the durability and heat resistance are improved, but the ceramic rod may be crushed during the assembling process

Engineering Contradiction:
Improvedurability of ceramic rodVSAvoidassembly process difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

A resilient component is introduced between the press fit element and the liquid conducting body to provide cushioning during assembly. This resilient component absorbs assembly forces and prevents direct impact on the ceramic rod, thereby avoiding crushing while maintaining the durability benefits of ceramic material.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The resilient component acts as an intermediary element between the press fit element and the liquid conducting body. It mediates the mechanical interaction during assembly, distributing forces evenly and protecting the fragile ceramic rod from crushing while still allowing the press fit element to secure the liquid conducting body in place.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If a press fit element is used to fix the liquid conducting body, then the structural stability is improved, but the liquid conducting body may be damaged during assembly

Engineering Contradiction:
Improvestructural stability of atomizing unitVSAvoidintegrity of liquid conducting body
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The resilient component is positioned between the press fit element and the liquid conducting body to provide beforehand cushioning. This cushioning layer ensures that when the press fit element is tightened, the force is gradually applied and distributed, preventing sudden crushing of the liquid conducting body while still achieving the desired structural stability.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The resilient component changes the mechanical parameters of the assembly process by introducing elasticity and compliance. It transforms the rigid press-fit interaction into a more controlled, progressive compression that maintains both structural stability and the integrity of the liquid conducting body.

Inventive Principle:
Principle #35Parameter changes

3Temperature

If the liquid conducting body is made of ceramic material, then the heat resistance is improved, but the material is more prone to crushing during assembly

Engineering Contradiction:
Improveheat resistanceVSAvoidresistance to crushing
Core Design Contradiction:
TemperatureVSStrength

Solution Approach 1:

The resilient component provides beforehand cushioning that specifically protects the ceramic liquid conducting body from crushing forces during assembly. This allows the ceramic material to maintain its superior heat resistance properties while the cushioning element compensates for its lower resistance to mechanical impact and compression during the assembly process.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The atomizing unit employs a composite structure combining ceramic liquid conducting body (for heat resistance) with resilient material (for mechanical protection). This composite approach leverages the strengths of each material: ceramic provides thermal stability while the resilient component provides mechanical protection against crushing.

Inventive Principle:
Principle #40Composite materials
