Problem

Conventional banknote stacking devices have complex structures and are inefficient in stacking large numbers of banknotes tidily, leading to potential misalignment and deformation issues during conveying.

Innovation Solution

A banknote stacking device with a simpler configuration, utilizing an input mechanism with upper and lower conveying belts, a stacking platform with baffles and an elastic strip, and a pressing and conveying mechanism with O-shaped belts to align and stack banknotes, along with an output mechanism for self-adaptive stacking and outputting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional banknote stacking device uses a complex mechanical clamping mechanism and impeller device to stack banknotes, then the stacking function is achieved, but the device complexity increases and the volume increases

Engineering Contradiction:
Improvestacking reliabilityVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the complex mechanical clamping mechanism and impeller device from the stacking system. Instead, it uses a simple platform mechanism where banknotes are conveyed one by one and stacked naturally under their own weight, eliminating unnecessary mechanical components while maintaining stacking functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The banknotes stack themselves automatically on the platform without requiring external clamping or manipulating mechanisms. The gravity of the banknotes themselves provides the stacking force, and the platform simply receives and accumulates them in an orderly manner.

Inventive Principle:
Principle #25Self-service

2Productivity

If the banknote stacking device processes a large number of banknotes, then the processing capacity increases, but the volume of the stacking mechanism increases and cost increases

Engineering Contradiction:
Improveprocessing capacityVSAvoidstacking mechanism volume
Core Design Contradiction:
ProductivityVSVolume of stationary object

Solution Approach 1:

The platform is designed to be movable rather than fixed, allowing it to adapt its position and capacity dynamically. The platform can be raised or lowered to accommodate different stack heights, and the entire stacking mechanism can be adjusted to handle varying volumes of banknotes without requiring a permanently large structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The simple platform mechanism serves multiple functions: it receives banknotes, stacks them in an orderly manner, and can accommodate varying quantities. This universal design eliminates the need for specialized large-volume mechanisms while maintaining high processing capacity.

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

3Reliability

If banknotes are conveyed through a complex mechanism, then the stacking function is achieved, but banknote deformation and misalignment issues occur

Engineering Contradiction:
Improvestacking reliabilityVSAvoidbanknote deformation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent removes the complex mechanical clamping and manipulating mechanisms that cause banknote deformation. By using a simple platform where banknotes are conveyed one by one and stacked under their own weight, it eliminates the harmful mechanical stresses that lead to misalignment and deformation.

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If auxiliary mechanisms are added to cooperate with the conveying mechanism, then the stacking function is improved, but the overall mechanism complexity increases

Engineering Contradiction:
Improvestacking reliabilityVSAvoidoverall mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the need for auxiliary mechanisms by using a straightforward platform-based stacking approach. Banknotes are conveyed one by one and stacked directly on the platform without requiring additional cooperative mechanisms, thereby reducing overall system complexity.

Inventive Principle:
Principle #2Taking out (Extraction)
