Solution Overview
Problem
Existing packaging machines for filtering paper pads with ground products of heterogeneous granularity face challenges in controlling the shape and ensuring the absence of product residues at the edges, as well as regulating the compactness of the pads.
Innovation Solution
A monobloc device combining measuring and compacting equipment ensures reliable production of flawless pads by using a rotating and translating compacting piston within a moving liner, with interchangeable dies for symmetric and asymmetric pad configurations, and adjustable compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate measuring and compacting equipment are used, then device flexibility is maintained, but manufacturing precision and reliability deteriorate due to alignment issues and operational inconsistencies
Solution Approach 1:
The patent combines the measuring equipment and compacting equipment into a single integrated monobloc device. The measuring screw (1) and compacting piston (2) are positioned within the same structural unit with a common reference plane, eliminating alignment issues between separate devices and ensuring consistent pad formation with clean edges.
2Reliability
If a monobloc structure is used, then manufacturing precision and reliability improve, but device complexity increases
Solution Approach 1:
While the overall device is a monobloc structure for reliability, the patent segments the compacting function into interchangeable dies (4) with different concavity configurations. This allows the same reliable monobloc structure to produce both symmetric and asymmetric pads by simply changing the die, rather than requiring different entire devices.
3Adaptability or versatility
If fixed compacting geometry is used, then device simplicity is maintained, but adaptability deteriorates for different pad configurations
Solution Approach 1:
The patent makes the compacting geometry dynamic and adjustable by providing interchangeable dies (4) that can be replaced based on production requirements. The measuring screw (1) and compacting piston (2) work with different die configurations to adapt to both symmetric and asymmetric pad requirements without changing the core monobloc structure.

AI summary
A combined device to feed and compact preset doses of ground coffee or other similar substances includes the combination of two operating devices, the first operating device including a measuring screw in an upright position, the second operating device including a compacting piston in an oblique position that is arranged perpendicular to concavities which are geometrically congruent with the morphology of the doses to be compacted inside dies located on a polygonal conveyer.
