Solution Overview

Problem

Conventional sorting-bundling integrated apparatuses require a linear pressing mechanism that occupies significant space and interferes with other functional modules, making it difficult to implement effectively.

Innovation Solution

A banknote stacking and tidying module with a vertical reciprocating pressing mechanism using a cam, pressing rod, and torsion spring, which eliminates the need for a linear pressing mechanism along the thickness direction, allowing for compact arrangement and efficient banknote pressing and conveying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a linear pressing mechanism is installed along the thickness direction of sheet media, then the pressing function is achieved, but the mechanism takes up much space and cannot be hidden into other functional sub-modules completely

Engineering Contradiction:
Improvespace occupationVSAvoidpressing function
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The pressing mechanism is transformed from a linear arrangement along the thickness direction to a rotational arrangement in the horizontal plane. The cam rotates about a vertical axis, and the pressing rod moves horizontally to apply pressing force, changing the dimension of the pressing action from vertical to horizontal, thus saving vertical space and enabling compact integration.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The pressing mechanism is integrated within the banknote stacking module structure. The cam and pressing rod are positioned such that the pressing action occurs within the existing module footprint, allowing the pressing function to be nested within the stacking module without requiring separate dedicated space.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Device complexity

If a linear pressing mechanism is installed along the thickness direction of sheet media, then the pressing function is achieved, but it cannot be hidden into other functional sub-modules completely and may affect the operation of other functional modules

Engineering Contradiction:
Improvemodule integrationVSAvoidoperation of other functional modules
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

By changing the pressing direction from vertical to horizontal, the mechanism fits within the horizontal plane of the stacking module, allowing better spatial integration with other functional modules operating in the vertical dimension, thus reducing interference.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The pressing mechanism is merged with the banknote stacking module, where the cam and pressing rod are integrated into the module's structural framework. The pressing rod is positioned to work in coordination with the stacking plates, combining the pressing function with the existing stacking operation without requiring separate module space.

Inventive Principle:
Principle #5Merging (Combining)

3Volume of moving object

If a cam mechanism is used for pressing banknotes, then the space occupation is reduced, but the mechanism complexity increases

Engineering Contradiction:
Improvespace occupationVSAvoidmechanism structure
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The cam mechanism serves multiple functions: it converts rotational motion to reciprocating motion, provides the pressing force through its profile, and automatically times the pressing action within the stacking cycle. This multi-functionality reduces the need for separate actuators and control mechanisms, offsetting the inherent cam complexity with functional consolidation.

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

Solution Approach 2:

The cam mechanism is self-actuating through the rotation of the cam drive shaft, which is driven by the module's existing drive system. The pressing rod automatically reciprocates as the cam rotates, eliminating the need for separate motors or actuators for the pressing action, thus reducing overall system complexity despite the cam's mechanical complexity.

Inventive Principle:
Principle #25Self-service
