Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for classifying value documents, such as bank notes, are not reliable and efficient due to separate processor units performing redundant evaluations on sensor data from different sensors, leading to inefficiencies and potential errors in classification.
Innovation Solution
An apparatus and method that combines sensor data from multiple sensors using an evaluation device to classify value documents based on waves reflected on both sides and properties captured in different regions, eliminating the need for redundant evaluations by merging and linking sensor data from various measuring principles, thereby enhancing reliability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate processor units are used for each sensor to perform pre-evaluation, then each sensor can be independently processed, but redundant evaluations occur and classification reliability decreases
Solution Approach 1:
The patent merges sensor data from multiple sensor devices into a single evaluation device, combining their outputs to form a unified classification result. This eliminates redundant evaluations and improves classification reliability by ensuring all sensor data is processed consistently in one centralized location rather than through multiple separate processor units that may produce conflicting results.
2Productivity
If separate processor units perform pre-evaluation of sensor data, then processing can be distributed, but redundant evaluations increase processing time and reduce efficiency
Solution Approach 1:
The patent consolidates evaluation functions into a single evaluation device that processes sensor data from multiple sensor devices simultaneously. This merging eliminates redundant pre-evaluation steps that occur when separate processor units independently analyze the same data, thereby reducing total processing time while maintaining comprehensive data analysis.
Solution Approach 2:
The sensor devices perform capturing of waves and generation of sensor data as preliminary actions before the unified evaluation. This allows the main evaluation device to receive pre-processed raw data that requires minimal additional processing, optimizing the overall processing efficiency by distributing only the necessary computational workload to the central evaluation device.
3Measurement precision
If sensor data are captured from multiple sensor devices, then classification accuracy can be improved, but data processing complexity increases
Solution Approach 1:
The patent merges sensor data from multiple sensor devices into a unified evaluation device, which processes all data through a single evaluation algorithm. This approach maintains high classification accuracy by incorporating data from multiple sources while reducing processing complexity compared to having multiple separate processor units, each requiring independent evaluation logic.

AI summary
An apparatus and method for classifying value documents includes least two sensor devices arranged to capture waves reflected on a front side and on a back side of a value document and to generate corresponding sensor data or to capture properties of the value document in at least two different regions of the value document by means of different measuring principles and to generate corresponding sensor data. At least one evaluation device is arranged to classify the value document with the aid of the sensor data generated by the at least two sensor devices, which sensor data relate to the waves reflected on the front side and back side of the value document or to the properties of the value document captured in the at least two different regions of the value document by means of different measuring principles.
