Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple specific atomizers are provided for different respiratory tracts, then precise dimensional atomization values are obtained, but device complexity and difficulty of operation increase
Solution Approach 1:
The patent implements a movable baffle element that can be positioned at different locations within the nebulization chamber to dynamically adjust the air-medicament mixture ratio. This single dynamic component replaces the need for multiple fixed atomizers, allowing the same atomizer to produce different particle sizes by varying the baffle position, thereby reducing device complexity while maintaining manufacturing precision
Solution Approach 2:
The patent makes a single atomizer multi-functional by combining it with a movable baffle system. The same atomizer can serve different respiratory tract treatment needs (upper respiratory tract, tracheo-bronchial tract, or pulmonary alveoli) by adjusting the baffle position, eliminating the need for multiple specialized atomizers and simplifying the device
2Manufacturing precision
If multiple specific atomizers are provided for different respiratory tracts, then precise dimensional atomization values are obtained, but ease of operation deteriorates due to component selection requirements
Solution Approach 1:
The patent implements a self-adjusting mechanism where the user simply rotates a control knob that automatically moves the baffle to the appropriate position based on the selected respiratory tract treatment mode. The system performs the adjustment function itself without requiring the user to manually select or replace atomizer components, making operation easier while maintaining precise dimensional atomization values
Solution Approach 2:
The patent introduces a control knob as an intermediary interface between the user and the complex baffle positioning mechanism. The knob provides a simple rotational interface that internally drives the baffle to predetermined positions through a transmission mechanism, shielding the user from the complexity of direct component selection while ensuring precise atomization
3Adaptability or versatility
If geometric positioning variation of components is implemented to obtain different nebulization, then device complexity increases, but disassembling for cleaning and sterilization becomes difficult
Solution Approach 1:
The patent divides the nebulization device into distinct separable modules: the atomizer assembly, the baffle assembly, the reservoir, and the mouthpiece assembly. Each module can be independently removed and cleaned. The baffle, which provides the geometric positioning variation for different nebulization modes, is designed as a separate component that can be easily detached from the chamber for sterilization without complicating the overall disassembly process
