Banknote Accumulation Mechanism for Collision-Free Cash Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote processing devices face issues with banknote collisions and accumulation failures due to the need for large mounting spaces and the risk of banknotes being pulled out during rotation, as well as difficulties in maintaining and recovering misplaced banknotes.
Innovation Solution
A banknote processing device incorporating an impeller-shaped wheel with a shallower banknote insertion angle, a lever mechanism to prevent collisions, and a movable pressing plate to ensure accurate accumulation, reducing the risk of banknote separation and improving maintenance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large number of banknotes are conveyed at once to the accumulation region, then the processing efficiency is improved, but the risk of collision and damage to banknotes increases
Solution Approach 1:
The accumulation region is divided into multiple compartments (first accumulation region and second accumulation region) separated by a partition wall. This segmentation allows banknotes to be conveyed in groups to different regions simultaneously, maintaining high processing efficiency while reducing collision risk within each smaller region.
Solution Approach 2:
A pressing plate is introduced as an intermediary component that applies pressure to banknotes in the accumulation region, keeping them neatly arranged and preventing collision. The pressing plate acts as a mediator between the conveyed banknotes and the accumulation region structure, ensuring orderly stacking without damage.
2Device complexity
If the structure is simplified to reduce complexity, then the device becomes easier to manufacture and maintain, but the ability to convey and manage large volumes of banknotes efficiently is reduced
Solution Approach 1:
The pressing plate serves multiple functions: it presses banknotes to keep them neatly arranged, prevents collision, and can be adjusted to accommodate different accumulation region configurations. This multi-functionality allows the device to maintain high processing capacity without adding proportionally complex structural elements.
Solution Approach 2:
The pressing plate is designed to be movable rather than fixed, allowing it to adapt to different banknote volumes and accumulation region configurations. This dynamic design enables the simplified structure to handle varying processing capacities efficiently without requiring multiple fixed components for different scenarios.
3Quantity of substance
If the accumulation region capacity is increased to handle more banknotes, then the processing efficiency is improved, but the risk of collision and damage to banknotes increases
Solution Approach 1:
The accumulation region is segmented into multiple compartments that can be filled sequentially. This allows the total capacity to be increased while maintaining smaller effective collision zones within each compartment, thus handling more banknotes without proportionally increasing collision risk.
Solution Approach 2:
The pressing plate acts as a mediator that distributes banknotes evenly within the accumulation region, preventing them from piling up in ways that cause collision. This intermediary component enables the system to safely accommodate larger quantities of banknotes by maintaining orderly arrangement throughout the expanded capacity.
