Engineering Contradictions & Design Principles
Engineering 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
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.
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.
2Device complexity
If manual substrate replacement is required frequently, then the device structure remains simple, but time is lost due to frequent interruptions
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.
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.
3Ease of operation
If substrates are exposed to external factors, then access is easy, but substrate quality deteriorates reducing service life
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.
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.
