Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the infusion cylinder is made non-dismountable to simplify structure, then structural complexity is reduced, but maintenance and cleaning become difficult
Solution Approach 1:
The infusion group is divided into separable components: the infusion cylinder (4) can be detached from the main body (6), and the closure piston (3) is a separate element. This segmentation allows the infusion cylinder to be removed for cleaning and maintenance while keeping the overall structure relatively simple when assembled.
2Ease of repair
If the infusion cylinder is made detachable to improve maintenance accessibility, then ease of repair is improved, but structural complexity increases
Solution Approach 1:
The infusion cylinder (4) is designed as a detachable component that can be separated from the main body (6) for maintenance. The connection mechanism uses simple positioning elements and elastic members rather than complex fastening systems, achieving ease of maintenance with minimal structural complexity.
3Reliability
If traditional infusion group structure is used, then functional reliability is maintained, but device bulkiness increases
Solution Approach 1:
The expulsion piston (29) is nested inside the infusion cylinder (4), and the speed multiplier mechanism components are arranged in a compact, space-efficient configuration within the main body (6). This nesting arrangement maintains functional reliability while reducing overall device bulkiness.
Solution Approach 2:
The carrier (9) holding the infusion cylinder (4) is designed to rotate about an axis orthogonal to the translation axis, allowing the infusion cylinder to be positioned in different orientations. This dimensional flexibility enables compact arrangement of components, reducing device bulkiness while maintaining functional reliability.

AI summary
The coffee machine infusion group comprises a closure piston (3) and an infusion cylinder (4) subjectable to a reversible movement between a position of engagement with the closure piston (3) for the creation of an infusion chamber (5) and a position of disengagement from the closure piston (3) for the loading of a coffee powder load (200), the infusion group having an expulsion system of the spent coffee powder load (200) from the infusion cylinder (4), the expulsion system comprising an expulsion piston (29) displaceably housed in the infusion cylinder (4), the expulsion system further comprising a speed multiplier mechanism operatively connecting the infusion cylinder (4) and the expulsion piston (29) for their relative displacement between a receiving position of the coffee powder load into the infusion cylinder (4) and an expelling position of the coffee powder load (200) from the infusion cylinder (4).
