Solution Overview
Problem
Existing coffee machines with height-adjustable dispensing heads suffer from inadequate fixation and reduced height adjustment travel, leading to risks of pivoting, tilting, and derailing, especially when in the low position, and are not robust enough.
Innovation Solution
Incorporating a third slide positioned between the first and second slides along a transverse axis, which interacts with the dispensing head to form a third slide connection, providing improved fixation and adjustment stroke, ensuring the dispensing head remains stable and adjustable for various container heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two slides are used for height adjustment, then the structure is simpler, but the attachment robustness deteriorates and the dispensing head may pivot or derail
Solution Approach 1:
The attachment structure is segmented into three independent slide connections instead of two. The first slide connects the front of the dispensing head to the frame, the second slide connects the rear, and the third slide provides additional lateral support. This segmentation distributes the mechanical loads and constraints across multiple independent connection points, preventing pivoting and derailing while maintaining structural simplicity.
2Device complexity
If two slides are used for height adjustment, then the device complexity is lower, but the height adjustment travel is reduced
Solution Approach 1:
The third slide is positioned laterally between the first and second slides along a transverse axis, adding a dimensional distribution of support points. This lateral arrangement creates a triangular support configuration that expands the effective adjustment envelope without requiring additional vertical space, thereby increasing the height adjustment stroke while keeping the device structure relatively simple.
3Ease of operation
If the dispensing head is positioned in the low position, then the reception area is more accessible, but the attachment stability deteriorates
Solution Approach 1:
The third slide provides localized lateral support specifically at the position between the first and second slides. This local reinforcement is particularly effective when the dispensing head is in the low position, as it prevents lateral pivoting and derailing that would otherwise occur due to reduced structural support. The local quality of support is optimized for the low-position operational requirements.

AI summary
This beverage dispensing machine includes a beverage dispensing head (18) whose position relative to a container receiving area is adjustable, and a receiving structure (29) for the dispensing head (18) comprising first (42) and second (44) slides adapted to interact with respective lateral sides (46, 48) of the dispensing head (18) to form first (52) and second (54) slide connections, respectively. According to the invention, the receiving structure (29) also includes a third slide (56), positioned between the first (42) and second (44) slides and adapted to interact with the dispensing head (18) to form a third slide connection (60). The third slide (56) is located along the longitudinal axis closer to the receiving area than the first (42) and second (44) slides.
