Pasty Compound Dispenser Spring Retaining Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for pasty compounds face challenges in achieving optimal discharge characteristics and retention, with limitations in spring element design affecting the efficiency and usability of pasty compound dispensing.
Innovation Solution
The dispenser features an annular retaining projection with a closed cross section, a valve section integrally formed on the retaining projection, and a hinge-like taper connecting the upward leg to the retaining projection, allowing for improved discharge characteristics and retention through a combination of material thickness and structural design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spring element is designed with a simple U-shaped section, then the device complexity is reduced, but the discharge characteristics and retention are insufficient
Solution Approach 1:
The spring element is divided into distinct functional sections: a leg section for mounting, an upwardly directed curvature for resilient return, and an annular retaining projection with integrated valve section for discharge control. This segmentation allows each part to optimize its specific function while maintaining overall reliability
Solution Approach 2:
The valve section is integrally formed on the retaining projection, merging the retention function and valve function into a single integrated structure. This eliminates the need for separate valve components while improving discharge characteristics
2Reliability
If the spring element uses a consistently convex valve section, then the manufacturing is simplified, but the discharge characteristics are suboptimal
Solution Approach 1:
The valve section features a concave profile on its radially outer side, creating a localized quality change that optimizes discharge characteristics. This concave region works with the唇 section to form an effective valve mechanism, while the rest of the structure remains manufacturable
3Reliability
If the retaining projection is designed with the same cross section as the membrane, then the device complexity is reduced, but the retention and discharge efficiency are compromised
Solution Approach 1:
The retaining projection is designed with an asymmetric cross section that is larger than the leg, with a closed cross section configuration. This asymmetric design provides superior retention while the integral valve section maintains manufacturing efficiency

Function Achieved in This Case
This design enhances the dispenser's ability to efficiently discharge pasty compounds while maintaining effective retention, offering improved haptics and long-lasting sound spring characteristics, ensuring reliable operation and user convenience.
Implementation Method 1
a spring element, which acts between the storage volume and the head piece and at the same time forms part of a delimiting wall of the discharge chamber, is provided in order to resiliently return the head piece upon a movement from a starting position into an actuation position

AI summary
A dispenser for compounds in paste form has a storage volume with a bounding part that can move conjointly when drawing from the storage volume, and a head piece that is guided relative to the storage volume. A discharge chamber with an inlet valve and an outlet valve has a discharge channel with a discharge opening. A spring element is active between the storage volume and the head piece, forms a bounding wall of the discharge chamber, and has a lower ear-shaped plug projection and an upper retaining profile. The spring element is designed as a leg that connects to the plug projection, which leg transitions into the retaining projection via an upwardly curved portion. The retaining profile is designed as a retaining projection that has a larger cross section than the leg, with an upper projection base which is enclosed in the retaining recess.
