Solution Overview

Problem

Existing document processing apparatuses for value documents, such as banknotes, often experience jams due to dog ears, folds, or crumples, making it difficult to access and remove jammed documents from the transport path.

Innovation Solution

The apparatus features a pivotable movable part that can be easily swung open to access the transport path, allowing for easy removal of jams, with a modular design that includes a singler for separating documents and a transport system with driven elements to manage document flow without needing transmission to the stationary part, and a sensor arrangement for controlling document routing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the apparatus uses a fixed enclosed transport path, then the document processing is protected and secure, but access to the transport path for removing jams becomes difficult

Engineering Contradiction:
ImproveAccess to transport path for jam removalVSAvoidDocument processing security and protection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The movable part is designed to be pivotable between a closed position (forming the transport path) and an open position (providing access to the transport path). This dynamic configuration allows the apparatus to switch between protected operation mode and maintenance/access mode, resolving the contradiction between security and accessibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The apparatus is divided into a stationary part and a movable part that can be separated spatially. The movable part containing output pockets can be pivoted away from the stationary part, creating access to the transport path while maintaining the integrity of the processing system. This segmentation enables independent access without compromising the overall system protection.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the apparatus includes a pivotable movable part for easy access, then jam removal becomes simple, but the device complexity increases

Engineering Contradiction:
ImproveJam removal easeVSAvoidStructure with movable and stationary parts
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pivotable movable part provides a simple mechanical solution for accessing the transport path. By using a single degree of freedom (pivoting motion), the design achieves easy access without requiring complex mechanisms, motors, or control systems that would increase device complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Instead of making the entire apparatus movable or using complex disassembly mechanisms, the invention inverts the approach by having a fixed stationary part and a movable part that opens away from it. This inversion simplifies the overall structure while providing the needed access functionality.

Inventive Principle:
Principle #13The other way round (Inversion)

3Device complexity

If the transport system uses driven elements contained in the movable part, then transmission to the stationary part is eliminated, but the movable part must bear additional mechanical load

Engineering Contradiction:
ImproveTransmission system complexityVSAvoidMechanical load on movable part
Core Design Contradiction:
Device complexityVSForce

Solution Approach 1:

The driven transport elements are merged with the movable part, eliminating the need for separate transmission mechanisms between stationary and movable parts. This consolidation simplifies the overall system architecture by integrating the drive function directly into the movable component.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The movable part serves multiple functions: it provides the output pockets for processed documents, enables access to the transport path when opened, and houses the driven transport elements. This multi-functionality reduces the need for additional components that would increase device complexity.

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