Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper sheet processing devices face challenges in aligning the ends of stacked banknotes neatly, leading to difficulties in handling and potential collapse during removal, and require separate binding mechanisms, increasing device size and cost.
Innovation Solution
A paper sheet processing device with a stacking unit featuring a vertically movable placing portion and a magnet coupling system that allows for tidy stacking and easy removal of processed paper sheets without binding, using a storage box with a slit for magnet coupling and an energizing member to maintain alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If banknotes are sequentially loaded into storage from a slot on the upper side, then processing capacity is maintained, but drop positions vary and ends cannot be aligned tidily
Solution Approach 1:
The patent inverts the conventional stacking approach by having banknotes pass through the bottom wall rather than being deposited from the top. The transport mechanism carries banknotes horizontally through the bottom wall into the storage space, allowing precise control of drop position and ensuring all banknotes align their ends tidily at the front surface.
2Ease of operation
If banknotes are stacked without binding, then handling is simpler, but bundles collapse when removed by hand
Solution Approach 1:
The patent employs the front surface of the storage box as a rigid support structure that maintains the aligned state of stacked banknotes. The box's front surface acts as a natural support that prevents collapse during stacking and removal, eliminating the need for additional binding mechanisms while maintaining bundle integrity.
3Stability of the object's composition
If a separate binding mechanism is added, then bundle stability improves, but device size and cost increase
Solution Approach 1:
The patent merges the stacking and support functions into the storage box structure itself. The front surface of the storage box serves dual purposes: it is both the structural element of the storage unit and the support surface that maintains banknote alignment. This integration eliminates the need for separate binding mechanisms, reducing device complexity and cost.
4Manufacturing precision
If operators manually align banknote ends, then alignment precision improves, but operation time increases
Solution Approach 1:
The patent implements preliminary alignment action through the transport mechanism, which automatically positions and orients banknotes before they enter the storage space. The horizontal transport through the bottom wall ensures that banknotes are already aligned with their ends facing the front surface, eliminating the need for manual alignment operations and reducing operation time.
