Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing stopper designs for diffusing a mist of nebulized droplets are complex, costly to manufacture, and require oversized drive mechanisms due to their curved ducts, which increases production costs and energy consumption.
Innovation Solution
A mast with a deflector wall that directs droplets downwards, featuring elongated openings and a rotatable plug with a cylindrical internal face, allowing for adjustable diffusion angles and simplified assembly, reduces material usage and manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If curved ducts are used in the stopper to orient the jet downwards, then the mist diffusion effectiveness is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
Instead of curving the duct to direct the jet, the invention inverts the approach by using a flat deflector wall perpendicular to the duct. The wall actively redirects the jet flow downwards at the exit, achieving the same orientation effect with a simpler flat structure rather than a complex curved duct.
Solution Approach 2:
The function of jet orientation is segmented into two separate components: the duct provides the flow path, while the deflector wall provides the orientation function. This separation allows each component to be simple in form while collectively achieving the complex function of directed mist diffusion.
2Reliability
If curved ducts with extensive material are used in the stopper, then the jet orientation function is achieved, but the stopper mass increases
Solution Approach 1:
The invention replaces the massive curved duct structure with a lightweight flat deflector wall. The wall is positioned at the duct exit and uses minimal material to redirect the jet flow, dramatically reducing the stopper mass while maintaining the jet orientation function.
Solution Approach 2:
The orientation function is extracted from the duct structure itself and placed into a separate, minimal deflector wall. This extraction allows the duct to remain simple and lightweight while the wall provides the necessary flow redirection with minimal material.
3Strength
If a massive stopper structure is used to ensure structural integrity, then the manufacturing robustness is improved, but the drive mechanism size and energy consumption increase
Solution Approach 1:
Instead of relying on a massive structure for strength, the invention inverts the approach by using a minimal flat wall that is strategically positioned to leverage the existing duct structure and flow dynamics, achieving structural adequacy with minimal material.
Solution Approach 2:
The minimal deflector wall counterbalances the functional requirements with minimal mass, creating a lightweight stopper that can be efficiently driven while maintaining the necessary structural integrity for jet orientation.

Function Achieved in This Case
The solution enables efficient and cost-effective diffusion of mist jets downwards, improving product freshness and appearance while reducing production costs and energy requirements.
Implementation Method 1
The wall forms a deflector which directs the flow of droplets upstream of the openings so that it leaves the mast while being directed downwards

AI summary
The mast (8) for diffusing a mist of droplets has at least one opening (20) that is elongate parallel to a main axis (16) of the mast. It comprises a flat wall (40) able to extend transversally to the axis, between a first part of the mast and the opening, being situated on the same side of the axis as this opening and forming a communication between the main part and the opening through the mast.
