Solution Overview

Problem

High-throughput banknote processing systems require rapid evaluation of large volumes of sensor data, necessitating high computing power, which is often expensive and complex, and the requirements can vary based on the number and type of sensors and processing speed.

Innovation Solution

A system with at least two evaluation units and a data bus, where each unit has interfaces for receiving and transmitting sensor data streams, a processor for evaluation, and a forwarding device for partial forwarding and storage, allowing for parallel evaluation using simpler processors and reducing the need for expensive hardware.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If high computing power is used to process sensor data in real time, then processing speed is improved, but device complexity and cost increase

Engineering Contradiction:
Improveprocessing speedVSAvoiddevice complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The evaluation system is divided into multiple independent evaluation units (first evaluation unit, second evaluation unit, etc.), each capable of processing sensor data in parallel. This segmentation allows the system to achieve high processing speeds without requiring a single complex high-power processor, thereby resolving the contradiction between processing speed and device complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple evaluation units are combined to work together on the same sensor data stream, with each unit performing different evaluation tasks or processing different portions of the data. This merging of multiple simple processors achieves the computational power of a complex processor while maintaining lower individual component complexity

Inventive Principle:
Principle #5Merging (Combining)

2Speed

If high computing power is used to process sensor data in real time, then processing speed is improved, but cost increases

Engineering Contradiction:
Improveprocessing speedVSAvoidcost
Core Design Contradiction:
SpeedVSEase of manufacture

Solution Approach 1:

The system uses multiple standard evaluation units instead of a single high-performance processor. Each evaluation unit can be manufactured using standard, cost-effective components, and their parallel arrangement achieves the required processing speed without the prohibitive cost of a single powerful processor

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The evaluation units are designed to be relatively simple and potentially replaceable components. Rather than investing in expensive, complex processors, the system uses multiple simpler units that can be manufactured more cheaply and replaced if needed, reducing overall system cost

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Measurement precision

If the number of sensors is increased to improve detection capability, then measurement precision is improved, but the amount of sensor data increases requiring more computing power

Engineering Contradiction:
Improvemeasurement precisionVSAvoidcomputing power requirement
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The sensor data processing is segmented across multiple evaluation units, with each unit handling a portion of the data or performing a specific type of analysis. This distribution prevents any single processor from becoming overwhelmed by the increased data volume from multiple sensors

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each evaluation unit is designed to be multi-functional, capable of processing data from different sensor types and performing various evaluation tasks. This universality allows the system to handle data from multiple sensors without requiring specialized processing hardware for each sensor type

Inventive Principle:
Principle #6Universality (Multi-functionality)
