Engineering Contradictions & Design Principles
Engineering 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
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.
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.
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
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.
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.
3Reliability
If banknotes are conveyed through a complex mechanism, then the stacking function is achieved, but banknote deformation and misalignment issues occur
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.
4Reliability
If auxiliary mechanisms are added to cooperate with the conveying mechanism, then the stacking function is improved, but the overall mechanism complexity increases
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.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables reliable and efficient stacking of a large number of banknotes in a tidy manner, reducing the complexity and cost of the mechanism while preventing deformation and misalignment, and ensuring smooth conveying processes.
Implementation Method 1
the friction force between the O-shaped belts and the banknotes drives the banknotes to move forward to a position of the front baffle
Implementation Method 2
The elastic strip is further provided on the platform, and the elastic strip has two ends fixed onto the platform, and a middle portion forming an arched elastic platform part. The elastic platform part is higher than the flat belt by 1mm to 2mm in a free state.
