Innovation Solution
A simplified aerosol-therapy device design featuring a compressor group with a reduced number of components, utilizing an inductive rotation motor, a piston-cylinder mechanism connected via an eccentric drive shaft, and an integrated cooling fan that also acts as an eccentric, along with an annular sealing membrane and check valve system for efficient air intake and delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional compressor group assembly is used, then the device structure is complete and functional, but the assembly time and assembly costs increase significantly
Solution Approach 1:
The patent integrates the compressor group components (motor, compressor device, cooling fan, and housing) into a pre-assembled unit that fits directly into the device housing as a single module. This merging of components reduces the number of separate assembly steps and decreases overall assembly time while maintaining complete device functionality.
Solution Approach 2:
The cooling fan is designed to serve dual functions: cooling the motor and acting as an eccentric to drive the compressor piston. This multi-functionality eliminates the need for separate cooling and driving mechanisms, thereby simplifying the assembly process and reducing assembly time.
2Reliability
If a traditional compressor group with multiple components is used, then the device is functional, but the number of components increases and maintenance requirements increase
Solution Approach 1:
The patent combines multiple compressor group components (motor, compressor, cooling fan, housing) into an integrated assembly where the cooling fan simultaneously serves as both a cooling device and an eccentric drive mechanism. This merging reduces the total component count while preserving all necessary functions.
Solution Approach 2:
The cooling fan is designed to perform multiple functions: it cools the motor through airflow and simultaneously acts as an eccentric to convert rotational motion into reciprocating motion for the piston. This multi-functionality eliminates redundant components and simplifies the overall device structure.
3Stability of the object's composition
If the cylinder is connected to the drive shaft with rigid connection, then the structure is stable, but oscillatory movements cannot be compensated
Solution Approach 1:
The patent employs a flexible membrane connecting the cylinder to the compressor housing, allowing the membrane to deform and absorb oscillatory movements generated during compression cycles. This flexible connection maintains structural stability while compensating for vibrations and slight oscillations.
Solution Approach 2:
The flexible membrane acts as a cushioning element that anticipates and absorbs oscillatory movements before they can cause structural issues. The membrane's elasticity provides built-in vibration damping, protecting the rigid connections from stress and maintaining overall structural stability.
