Counterfeit Bill Sorting via Segmented Storage and Discrimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bill-binding machines lack the ability to uniformly handle rejected bills, as they eject all exempted bills to a single storage compartment without specifying the reason for rejection, making it difficult for operators to treat counterfeit or unknown denomination bills appropriately.
Innovation Solution
A paper processing apparatus and system that includes a discriminating unit and storage compartments, where the apparatus conveys papers to storage compartments based on discrimination results, allowing only counterfeit bills to be ejected to a specific compartment, enabling operators to manage rejected bills more effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all rejected bills are ejected to a single storage compartment, then the device structure is simplified, but the operator cannot uniformly handle different types of rejected bills (counterfeit vs. unknown denomination)
Solution Approach 1:
The storage compartment is segmented into multiple sections: a first storage compartment for counterfeit bills and a second storage compartment for bills of unknown denomination. This segmentation allows the operator to uniformly handle different types of rejected bills by directing them to appropriate compartments based on discrimination results, while maintaining a relatively simple overall device structure.
2Adaptability or versatility
If multiple storage compartments are added to separate counterfeit bills from other rejected bills, then the handling of rejected bills is improved, but the device complexity increases
Solution Approach 1:
A conveying mechanism acts as an intermediary between the discrimination device and the storage compartments. This intermediary automatically directs discriminated bills to the appropriate storage compartment based on discrimination results, reducing the need for complex manual sorting mechanisms while achieving versatile sorting functionality.
Solution Approach 2:
The counterfeit bill identification and sorting function is extracted as a separate capability from the general bill handling process. The discrimination device identifies counterfeit bills specifically, and the conveying mechanism extracts these identified bills to a dedicated first storage compartment, allowing the system to maintain adaptability while managing complexity through functional separation.
3Productivity
If the apparatus automatically discriminates and sorts bills, then productivity is improved, but the device complexity increases due to additional discrimination and conveying components
Solution Approach 1:
The discrimination of bills is performed as a preliminary action before the bills reach the storage compartments. By identifying counterfeit bills and determining their destination in advance, the system enables automated sorting and improves processing efficiency without requiring complex real-time decision-making mechanisms during the conveyance and storage phases.

AI summary
A paper processing apparatus includes a discriminating unit. The discriminating unit can discriminate papers inserted into the papers processing apparatus. Discriminated papers are ejected to storage compartments based on discrimination results. Only papers that are discriminated as counterfeit are ejected to one of the storage compartments.
