Adapter Plate Protrusions Prevent Pump Misalignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior adapter plates in beverage systems can become misaligned during use, leading to leaks due to movement or loosening, which compromises the alignment between the adapter plate and the pump head.
Innovation Solution
The introduction of an adapter plate with protrusions and depressions that align with corresponding features on the pump head, combined with a locking ring, ensures a geometric lock and maintains proper alignment, preventing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adapter plate is secured to the pump head, then the alignment between the adapter plate and pump head is maintained, but the adapter plate may become loose or misaligned during use due to vibration or movement
Solution Approach 1:
The adapter plate is divided into multiple functional features: a body portion, a piston opening, a water opening, and crucially, protrusions that extend from the body. These segmented features allow the adapter plate to maintain alignment through the protrusions engaging with corresponding depressions in the pump head, while the body portion provides the mounting surface for the piston and water connections.
Solution Approach 2:
The adapter plate incorporates asymmetric protrusions that extend from specific locations on the body portion. These protrusions are positioned to engage with corresponding asymmetric depressions in the pump head, creating a unique geometric lock that prevents rotation or misalignment. The asymmetric design ensures that only the correct orientation of the adapter plate will allow proper engagement of all protrusions with their corresponding features.
2Manufacturing precision
If the adapter plate moves during use, then the alignment between the adapter plate and pump head is lost, but adding alignment features increases device complexity
Solution Approach 1:
The adapter plate design merges multiple functions into a single component: the body portion provides the mounting surface, the piston opening accommodates the piston, the water opening connects to the water port, and the protrusions provide alignment and locking. By combining these features into one integrated adapter plate rather than separate components, the design achieves precise alignment without significantly increasing overall device complexity.
Solution Approach 2:
The protrusions act as intermediary elements between the adapter plate and the pump head. These protrusions engage with corresponding depressions in the pump head to transmit alignment forces and maintain the geometric lock. The intermediary protrusions simplify the connection by providing discrete engagement points rather than requiring complex mating surfaces throughout the entire interface.
3Reliability
If the adapter plate is locked to the pump head, then leakage is prevented, but the locking mechanism increases assembly complexity
Solution Approach 1:
The adapter plate is designed with protrusions that are pre-positioned to engage with corresponding depressions in the pump head during assembly. This preliminary geometric locking action occurs automatically as the adapter plate is installed, creating the alignment and seal before any additional locking steps are required. The protrusions are formed as integral features of the adapter plate rather than requiring separate locking components.
Solution Approach 2:
The geometric lock formed by the protrusions and corresponding depressions is self-forming during assembly. As the adapter plate is installed onto the pump head, the protrusions automatically engage with the depressions to create the locking relationship and ensure proper alignment. This self-locking mechanism eliminates the need for separate locking components or complex assembly procedures, as the adapter plate serves its own locking function through its geometric design.

AI summary
A beverage system includes a pump that draws a set amount of a flavored concentrate into a mixing chamber for mixing with water to form a beverage. A pump head includes a piston opening that receives a piston and a water port that defines a water flow path. The pump head includes protrusions. An adapter plate includes a piston opening that receives the piston and a water opening that receives the water port of the pump head. The adapter plate includes depressions. When the adapter plate is installed in the pump, the piston opening of the adapter plate and the piston opening of the pump head align, and the water port of the pump head is received in the water opening of the adapter plate. The protrusions of the pump heads are received in the depressions of the adapter plate, aligning the pump head and the adapter plate.
