Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manual trigger mode is used for atomization, then the device structure can be simple, but the accuracy of drug administration deteriorates due to hand-mouth coordination errors

Engineering Contradiction:

Improvetrigger structure complexityVSAvoiddrug administration accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent replaces the manual mechanical trigger operation with an automatic sensing system. An air pressure sensor detects changes in air pressure caused by patient inhalation, and this signal automatically triggers the atomization driver to activate the atomization module, eliminating the need for manual button pressing and improving dosing accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-triggering atomization where the patient's own inhalation action serves as the trigger signal. The air pressure sensor monitors the patient's breathing pattern and automatically initiates atomization when inhalation is detected, making the system self-regulating without requiring external manual intervention.

Inventive Principle:

Principle #25Self-service

2Measurement precision

If automatic trigger based on air pressure sensor is implemented, then the accuracy of drug administration is improved, but the device complexity increases

Engineering Contradiction:

Improvedrug administration accuracyVSAvoidtrigger structure complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The air pressure sensor serves multiple functions: it monitors patient inhalation, triggers atomization, and can potentially track breathing patterns. The gas guide channel integrates both medication delivery and pressure sensing functions. This multi-functionality reduces the need for separate components, mitigating the increase in overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the trigger mechanism with the existing atomization system by using the air pressure sensor integrated into the atomization module. The gas guide channel that delivers medication also serves as the pathway for pressure sensing. This merging of functions adds automation capability while minimizing additional structural complexity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An inspiratory trigger atomizer for a patient with an airway disease, including: a main body including an atomization module and a nozzle connected thereto; an atomization driver; an air pressure sensor electrically connected to the driver, and a gas guide channel arranged in the main body, with a first end located in the nozzle and a second at a monitoring end of the sensor. The sensor acquires the air pressure in the nozzle that changes with the patient's breathing, identifies the inhalation state of the patient and generates a corresponding signal to trigger a main unit module to start the atomization driver. The atomizer has an extremely short inspiratory trigger response time, such that atomization can be quickly triggered after the patient inhales, and with atomization duration being 1.5 s, the patient can fully inhale a drug, so the atomizer can be applied to a wide range of people.
