Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the nebulizer sprays at a fixed rate without active detection, then the device structure is simple, but asynchronous phenomenon between nebulization and respiration occurs
Solution Approach 1:
The patent implements a feedback mechanism where a sensor detects the respiratory rate of the user in real-time, and the control unit adjusts the nebulization frequency accordingly. The sensor signals are transmitted to the control unit, which automatically regulates the nebulization module to match the user's breathing rhythm, ensuring synchronized nebulization and respiration.
Solution Approach 2:
The system performs self-adjustment by automatically detecting respiratory parameters and regulating nebulization frequency without requiring manual intervention. The control unit autonomously processes sensor data and modifies operating parameters to maintain optimal synchronization between nebulization and user respiration.
2Reliability
If the gas flow detection structure is added to detect respiratory rate, then the synchronization of nebulization and respiration is improved, but the device complexity increases
Solution Approach 1:
The gas flow detection structure serves multiple functions: it detects respiratory rate for synchronization control, monitors gas flow through the ventilator circuit, and provides feedback for automatic frequency adjustment. This multi-functionality reduces the need for separate detection systems, thereby limiting the increase in device complexity while achieving reliable synchronization.
Solution Approach 2:
The patent combines the gas flow detection function with the existing nebulization device structure. The sensor and control unit are integrated into the nebulization apparatus, merging respiratory detection, nebulization control, and frequency adjustment into a single unified system, thus minimizing the increase in overall device complexity.
3Measurement precision
If the sensor is placed in the gas flow chamber, then the gas flow detection precision is improved, but the sensor is vulnerable to water damage
Solution Approach 1:
The patent employs a waterproof protective structure, likely involving flexible membranes or sealed housings, to protect the sensor from water exposure while allowing it to remain positioned in the gas flow chamber for accurate detection. This protective barrier enables the sensor to maintain high measurement precision without being vulnerable to water damage from accumulated nebulized liquid.
Solution Approach 2:
A protective intermediate structure or material is introduced between the sensor and the water-containing environment. This intermediary element allows the sensor to detect gas flow accurately while preventing direct contact with water, thus resolving the conflict between detection precision and water vulnerability.
4Measurement precision
If the partition plate is added to divide the nozzle, then the gas flow detection precision is improved, but the manufacturing complexity increases
Solution Approach 1:
The nozzle is segmented by a partition plate that divides it into separate chambers: a nebulization chamber and a gas flow detection chamber. This segmentation allows the sensor to be positioned in the detection chamber where gas flow patterns are more predictable and measurable, improving detection precision. The partition plate creates distinct functional zones within the nozzle structure.
Solution Approach 2:
The partition plate introduces a spatial dimension to the nozzle design, creating separate three-dimensional zones for nebulization and detection functions. This dimensional separation allows optimized gas flow paths for each function, improving measurement precision while the partition plate itself can be manufactured using standard machining or molding techniques.
