Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oscillating armature pumps for beverage machines suffer from instability, noise emission, and require multiple components, leading to increased complexity and material usage.
Innovation Solution
A working piston with a direct connection point between the piston part and magnet element, allowing for improved force transmission and stability, reduced noise, and fewer components, using a deep-drawn piston part and magnet element with a form-fitting connection, and a compensation piece for fluidic interconnection of chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the piston part and magnet element are pressed against one another only by spring force, then the structure is simpler with separate components, but stability is reduced and impact occurs leading to noise emission
Solution Approach 1:
The patent merges the piston part and magnet element into a single integrated working piston component. The magnet element is directly connected to the piston part through a connection point, eliminating the need for spring force to maintain contact. This integration improves stability and prevents impact-related noise while reducing the number of separate components.
2Object-generated harmful factors
If the piston part and magnet element are pressed against one another only by spring force, then components can be separate, but impact between components occurs leading to increased noise emission
Solution Approach 1:
By integrating the magnet element and piston part into a single working piston with a direct connection point, the invention eliminates impact between separate components. This merger removes the source of impact noise while maintaining a relatively simple component arrangement, as the connection is achieved through a straightforward structural integration rather than complex damping mechanisms.
3Force
If separate piston part and magnet element are used with spring force, then components are modular, but force transmission is less efficient
Solution Approach 1:
The integration of the magnet element and piston part creates a direct force transmission path through the connection point. This eliminates intermediate spring elements and potential slip interfaces, enabling more efficient transmission of electromagnetic forces from the magnet element to the piston part. The unified structure ensures that forces are transmitted directly without loss or delay.
