Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a packaging apparatus with a rotor and vibrating means is used to compact filter bags, then the longitudinal encumbrance of filter bag groups is reduced, but the apparatus cannot accommodate packaging stations at different heights
Solution Approach 1:
The patent employs a dynamic transfer unit with movable trays that can be positioned at different heights and angles. The trays are mounted on a rotating arm mechanism that allows them to move between a loading position (lower height) and a packaging position (higher height), enabling the apparatus to accommodate packaging stations at varying elevations while maintaining the compacting function.
Solution Approach 2:
The invention introduces vertical dimensionality to the transfer mechanism by positioning the packaging station at a higher elevation than the loading station. The transfer unit moves trays vertically and rotationally from the lower loading area to the upper packaging area, adding a vertical movement dimension that resolves the height adaptation problem while preserving horizontal compacting capabilities.
2Quantity of substance
If filter bags are arranged in ordered groups with maximum longitudinal encumbrance, then all filter bags can be contained, but the packaging container size and storage space increase
Solution Approach 1:
The patent utilizes vibrating means applied to the trays to agitate and redistribute the filter bags during the transfer process. This vibration causes the bags to settle more compactly within the trays, reducing air gaps and achieving denser packing arrangements that minimize longitudinal encumbrance while maintaining the required quantity of bags per group.
Solution Approach 2:
The invention changes the physical state and arrangement parameters of the filter bags through mechanical manipulation. By applying vibration and rotational movement, the bags transition from a loose, extended arrangement to a compact, densely packed configuration, effectively reducing the longitudinal dimension while preserving the total number of bags.
3Productivity
If a transfer unit with rotating trays is used to form and transport filter bag groups, then groups can be fed to packaging stations, but the apparatus complexity increases
Solution Approach 1:
The transfer unit with rotating trays serves multiple functions simultaneously: it forms groups of filter bags, transports them from the loading station, positions them at the appropriate angle, and delivers them to the packaging station. This multi-functionality consolidates several operations into a single mechanism, improving productivity without proportionally increasing complexity.
Solution Approach 2:
The invention merges the group formation process with the transport mechanism. The trays both contain the filter bags during grouping and serve as the transport medium to the packaging station, combining formation and transportation functions into a unified system that reduces overall apparatus complexity.
