Bill Receiving Box With Dual Pressing Boards for 700+ Bills
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bill receiving apparatuses are limited in capacity, requiring frequent retrieval of cash boxes due to the instability of pressing mechanisms when handling more than 700 sheets of bills, leading to potential jamming issues.
Innovation Solution
A bill receiving box design featuring dual pressing boards and springs that allow for stable receipt and storage of at least 700 sheets, with the capability to handle up to 1,000 sheets by using front and rear pressing boards and springs that sequentially press bills into a receiving space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the bill receiving space and sliding travel of the pressing board are increased to receive more than 700 sheets of bills, then the bill receiving capacity is improved, but the operation stability deteriorates and bill jam occurs
Solution Approach 1:
The single pressing board is divided into front and rear pressing boards, with the front pressing board for receiving bills and the rear pressing board for pushing bills. This segmentation allows each pressing board to have optimized dimensions and travel distance, maintaining stability while increasing overall capacity to receive more than 700 sheets of bills.
2Quantity of substance
If the elastic force and operation travel of the spring are increased to handle more bills, then the bill receiving capacity is improved, but the operation stability deteriorates
Solution Approach 1:
The single spring is divided into front and rear springs. The front spring connects the front pressing board to the rear pressing board, and the rear spring connects the rear pressing board to the box body. This segmentation allows each spring to have optimized elastic force and travel, maintaining operational stability while enabling the system to handle more than 700 sheets of bills.
3Quantity of substance
If a single pressing board and spring are used, then the device complexity is reduced, but the bill receiving capacity is limited to 100-500 sheets
Solution Approach 1:
The pressing mechanism is segmented into front and rear pressing boards with corresponding front and rear springs. This segmentation enables the system to receive more than 700 sheets of bills by distributing the pressing function across multiple components, each with optimized dimensions and travel distance.
Solution Approach 2:
The pressing mechanism utilizes the front-rear dimension by positioning the front and rear pressing boards at different locations along the bill insertion path. This dimensional arrangement allows bills to be received and pressed in sequence, increasing capacity while maintaining manageable complexity through spatial distribution of functions.
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
Enhances operational stability and reduces the frequency and time needed for manual retrieval by enabling the secure storage of a larger number of bills without jamming.
Implementation Method 1
a spring for returning the pressing board. When a bill enters the passage via the bill inlet, the delivery device of the bill receiving device is activated to move the bill rearward... the pressing board is biased by the elastic returning force of the spring to press against the bill for positioning and storage
Implementation Method 2
The bottom cover is pivotably connected to the bottom portion of the box body and is configured for controlling opening and closing of the bill retrieving opening

AI summary
A bill receiving box includes a box body having a bill pressing opening intercommunicating with a receiving space of the box body for receiving bills. Front and rear pressing boards are slidably received in the receiving space and spaced from each other. Front and rear springs are disposed in the receiving space of the box body. Two ends of the front spring respectively abut against the front pressing board and the rear pressing board. Two ends of the rear spring respectively abut against the rear pressing board and a rear end of the box body. The rear spring biases the rear pressing board and the front spring forward, and the front spring biases the front pressing board forward, such that the front pressing board presses the bills forward to abut against a rear side of the bill pressing opening. The receiving space receives at least 700 sheets of stacked bills.
