Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single substrate is used for atomization, then the device structure is simple, but the substrate needs frequent manual replacement leading to poor user experience

Engineering Contradiction:
Improvedevice structureVSAvoiduser experience
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The substrate is segmented into multiple individual substrate units arranged in an array, where each unit can be independently atomized. This allows the device to continue operating with remaining units after some are used, eliminating frequent manual replacements while maintaining a relatively simple overall device structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple substrate units are pre-loaded into the device in advance. This preliminary action ensures that the device has a sufficient supply of substrates ready for atomization, allowing continuous operation without requiring frequent user intervention to replace substrates.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If manual substrate replacement is required frequently, then the device structure remains simple, but time is lost due to frequent interruptions

Engineering Contradiction:
Improvesubstrate loading mechanismVSAvoidtime for substrate replacement
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The substrate array divides the total substrate supply into multiple independent units, allowing the device to atomize through one unit while others remain available. This segmentation eliminates the need for frequent stop-and-replace operations, significantly reducing time loss while keeping the loading mechanism simple.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device maintains continuous atomization operation by having multiple substrate units available in the array. As one unit is atomized, the device can seamlessly transition to the next unit without interruption, ensuring continuous useful action and eliminating downtime associated with manual replacement.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of operation

If substrates are exposed to external factors, then access is easy, but substrate quality deteriorates reducing service life

Engineering Contradiction:
Improvesubstrate accessibilityVSAvoidsubstrate service life
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The substrate array is nested within a protective housing assembly that shields the substrates from external factors such as moisture, air, and contamination. This nested structure protects substrate quality and extends service life while still allowing easy access through the housing opening when needed.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The housing assembly acts as a flexible protective shell that encloses the substrate array, providing a barrier against external environmental factors. This shell structure maintains substrate integrity and quality while allowing controlled access when required for loading or replacement.

Inventive Principle:
Principle #30Flexible shells and thin films
