Deformable Chamber Priming via Rotational Assembly and Segmented Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid dispensers face challenges with priming difficulties due to air-filled chambers and inefficient use of reservoir volume, particularly when the deformable chamber's deformation rate is low, leading to a 'dead zone' within the chamber.
Innovation Solution
A method for manufacturing a device with a deformable chamber and a reservoir, where the chamber is filled through a filling valve, and the chamber is rotated relative to the reservoir during assembly to ensure proper priming and minimize the dead zone, utilizing a thinner filling pipe for the chamber and a larger pipe for the reservoir to facilitate efficient filling and product distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the chamber is filled manually by pressing to pump product from reservoir, then the chamber can be filled with product, but the priming process is difficult and time-consuming
Solution Approach 1:
The chamber is pre-filled with product through the filling valve before the device is put into service. This preliminary action eliminates the need for manual priming operations, as the chamber starts in a ready-to-use state with product already present, directly resolving the technical contradiction between ease of operation and time loss during priming
Solution Approach 2:
The filling operation is extracted from the manual priming process and performed separately through the filling valve during manufacturing or initial setup. This separates the filling function from the user-operated priming action, allowing automated or assisted filling that reduces both operational difficulty and time requirements
2Stability of the object's composition
If the deformable chamber has low deformation rate, then the chamber structure is stable, but a dead zone forms in the chamber reducing product distribution efficiency
Solution Approach 1:
The filling process is segmented into controlled stages through the filling valve mechanism, allowing product to be introduced in a manner that prevents dead zone formation. The valve enables precise control over filling dynamics, maintaining chamber stability while ensuring complete product distribution without requiring high deformation rates
Solution Approach 2:
The filling valve allows control of filling parameters (flow rate, pressure, timing) to optimize the filling process. By adjusting these parameters, the system maintains chamber structural stability while preventing dead zone formation, thereby improving product distribution efficiency without increasing deformation rate

Function Achieved in This Case
This method improves priming efficiency by ensuring the chamber is filled effectively, reducing the dead zone, and allowing for better product distribution, enhancing the overall performance of the dispensing device.
Implementation Method 1
a filling valve for the passage of the product from the reservoir toward the deformable chamber
Implementation Method 2
the interior of the deformable chamber being delimited at least in part by a movable wall of which displacement causes a variation of the volume of the deformable chamber

AI summary
A method for manufacturing a device for dispensing a product, including a supply of a device having a reservoir, the reservoir being connected to a deformable chamber and being provided with a filling opening, the interior of the deformable chamber being delimited at least in part by a movable wall, a displacement of which causes a variation in the volume of the deformable chamber, a step of filling of the chamber deformable through a filling valve, a step of filling of the reservoir with product, and a closing step in which the filling opening is closed. Application includes, for example, the pharmaceutical or cosmetic or agro-food industry.
