Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the article is continuously used to extend its service life, then the productivity is improved, but the reliability deteriorates due to component degradation
Solution Approach 1:
The system is divided into two main segments: a reusable aerosol provision device and a replaceable article. The article can be separated from the device and refilled independently, allowing the consumable material to be replenished without replacing the entire assembly. This segmentation enables continuous use of the same article with refilling, extending service life while maintaining reliability through controlled refilling processes.
Solution Approach 2:
A refilling device acts as an intermediary system between the reservoir of aerosol-generating material and the article. The refilling device includes a motor-driven interface that precisely controls the transfer of material from the reservoir to the article, preventing overfilling and ensuring accurate refilling. This intermediary mechanism protects the article from degradation caused by improper refilling while enabling extended service life.
2Device complexity
If manual refilling is used, then the device complexity is reduced, but the manufacturing precision and control of refilling process deteriorates
Solution Approach 1:
The refilling device is designed to automatically perform the refilling operation without requiring manual intervention during the actual transfer process. The motor-driven interface autonomously positions the article interface relative to the reservoir interface and controls the material transfer, providing precise refilling control while maintaining relatively simple overall device architecture.
Solution Approach 2:
The refilling process replaces manual mechanical operations with an automated motor-driven interface system. The motor precisely controls the movement of the article interface and the timing of material transfer from the reservoir, achieving high manufacturing precision and controlled refilling without complex mechanical linkages or multiple moving parts.
3Productivity
If the article is refilled multiple times, then the productivity is improved, but the reliability deteriorates due to repeated use
Solution Approach 1:
The refilling device incorporates detection mechanisms that monitor the refilling process and provide feedback to the control system. The system detects when the article interface engages with the reservoir interface, when material transfer is complete, and can identify potential issues such as leaks or improper positioning. This feedback enables controlled multiple refilling operations while maintaining reliability by preventing conditions that would cause degradation.
Solution Approach 2:
The refilling device is designed with protective features that prevent damage to the article during refilling operations. The motor-driven interface system carefully controls the positioning and engagement of components, and the detection mechanisms can identify potential problems before they cause reliability issues. This beforehand cushioning allows multiple refilling cycles without compromising the article's reliability.
