Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Banknote receiving devices with blade wheel structures face limitations in maximizing banknote stacking space while maintaining orderly stacking.
Innovation Solution
A banknote receiving device with a blade wheel floating control system, where a movable support plate adjusts banknote receiving space based on the upward floating degree of the blade wheel, utilizing a coded disc, sensor, and tension springs to control the blade wheel's movement and support plate's downward displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the banknote support plate is fixed, then the banknotes can be stacked orderly, but the banknote stacking space is limited
Solution Approach 1:
The support plate is transformed from a fixed structure to a movable one, capable of vertical displacement. The blade wheel is also made movable through the floating control mechanism. This dynamic design allows the system to adapt to varying banknote quantities while maintaining orderly stacking, resolving the contradiction between stability and space.
Solution Approach 2:
The position parameter of the support plate is made variable through the transmission mechanism, allowing it to move vertically. The blade wheel's position parameter is also changed through the floating control device. These parameter changes enable the system to expand stacking space without compromising the orderly arrangement of banknotes.
2Quantity of substance
If the banknote support plate is flexibly movable, then the number of stacked banknotes may be increased, but the banknote stacking space is still limited
Solution Approach 1:
The blade wheel is nested within the supporting frame with floating capability, allowing it to move vertically within the frame's constraints. The support plate is nested below the blade wheel and can also move vertically. This nested structure enables multi-level expansion of stacking space while maintaining system compactness.
Solution Approach 2:
The system transitions from a single-level stacking approach to a multi-level vertical stacking system. The blade wheel and support plate operate in different vertical levels, with the blade wheel floating at an upper level and the support plate at a lower level. This dimensional separation significantly increases the effective stacking space and capacity.
3Volume of moving object
If the blade wheel is made floatable, then the banknote receiving space can be increased, but the device complexity increases
Solution Approach 1:
The floating control device incorporates a feedback mechanism where the sensor detects the position of the coded disc on the rotating shaft, and this information is used to control the support plate's movement. This feedback loop enables automatic adjustment of the blade wheel's floating position, simplifying the control process and reducing operational complexity despite the increased mechanical complexity.
Solution Approach 2:
The patent replaces complex mechanical floating control mechanisms with a sensor-based detection system and transmission mechanism. Instead of using complex mechanical linkages to control the blade wheel's floating, the system uses the sensor to detect position and the transmission mechanism to convert rotational motion into vertical displacement, simplifying the overall control system.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous and compact stacking of an infinite number of banknotes by increasing the banknote receiving space dynamically, ensuring orderly and efficient stacking.
Implementation Method 1
a pair of tension springs arranged symmetrically. Each of the tension springs has an upper end fixed on the respective bearing of the rotating shaft and a lower end fixed on the respective lateral plate of the supporting frame
Implementation Method 2
The coded disc is configured to optionally block a light-transmittable point of the sensor when the coded disc floats up and down with the blade wheel, to allow the sensor to sense the upward floating degree of the blade wheel
