Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the infusion cylinder is made non-dismountable to simplify structure, then device complexity is reduced, but ease of maintenance deteriorates
Solution Approach 1:
The infusion group is divided into separable components: the infusion cylinder can be detached from the main body, and the piston assembly can be removed from the cylinder. This segmentation allows each component to be independently maintained or replaced without dismantling the entire device, thus simplifying the overall structure while improving maintenance accessibility.
2Ease of repair
If the infusion cylinder is made dismountable to improve maintenance accessibility, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The infusion cylinder is designed as a separate, removable component that can be detached from the main body without requiring complex disassembly procedures. The piston assembly within the cylinder can also be independently removed. This segmentation achieves easy maintenance accessibility while keeping the structural complexity manageable through straightforward connection and detachment mechanisms.
3Ease of manufacture
If traditional infusion group structure is used, then manufacturing simplicity is maintained, but device bulk increases
Solution Approach 1:
The piston assembly is nested within the infusion cylinder, and the infusion cylinder itself can be nested within or integrated with the main body structure. This nesting arrangement allows multiple components to occupy overlapping or adjacent spaces efficiently, reducing the overall device bulk while maintaining manufacturing simplicity through conventional assembly techniques.

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