Bill Processing Device Denomination Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bill processing devices with three storage boxes, including a one thousand-yen bill storage box, a mix box for multiple denominations, and an examination box, face difficulties in efficiently dispensing higher denomination bills like the five thousand-yen bill due to random storage of ten thousand-yen, five thousand-yen, and two thousand-yen bills in the mix box, leading to increased dispensing time.
Innovation Solution
The device is configured with a first denomination bill storage box, a mix box for storing multiple denominations in a mixed manner, and an examination box that functions as a temporary storage for recounting, where only second denomination bills are stored in the examination or mix box, allowing for separate processing and rapid dispensing of specific denominations like the five thousand-yen bill by rearranging and switching bills between storage boxes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple denominations of bills are stored in a mixed manner in the mix box, then the storage space is saved and the device complexity is reduced, but the dispensing time for specific denominations is increased
Solution Approach 1:
The patent divides the storage system into separate compartments: a first storage box for one thousand-yen bills, a second storage box for five thousand-yen bills, and a third storage box for other denominations. This segmentation allows each denomination to be stored separately, enabling rapid dispensing without mixing, thus resolving the contradiction between simplified storage structure and fast dispensing operation.
Solution Approach 2:
The patent introduces a movable partition wall that can shift between positions to dynamically adjust the boundaries between storage boxes. This dynamic configuration allows the system to adapt to different storage needs while maintaining separate compartments for different denominations, ensuring both structural simplicity and operational efficiency.
2Device complexity
If bills of different denominations are stored in a mixed manner, then the quantity of storage boxes is reduced, but the productivity of dispensing operations is decreased
Solution Approach 1:
The patent implements separate storage compartments for different bill denominations using partition walls, allowing efficient dispensing of specific denominations while maintaining a compact overall structure. This segmentation enables high productivity without requiring multiple independent storage units.
Solution Approach 2:
The third storage box serves multiple functions: it stores bills of various denominations other than one thousand-yen and five thousand-yen bills, and also acts as a buffer during dispensing operations. This multi-functionality reduces the total number of storage boxes needed while maintaining high dispensing efficiency.

AI summary
A bill processing device includes: a first denomination bill storage box configured to store therein first denomination bills to be used as change; a mix box configured to store therein a plurality of denominations of bills other than the first denomination bills in a mixed manner; and an examination box configured to function as a temporary storage box in examination of recounting numbers of bills stored in the first denomination bill storage box and the mix box, the bill processing device being configured to perform reception and dispensing processing of bills. Only second denomination bills to be used as change are stored in the examination box or the mix box in the reception or after the examination, and the second denomination bills stored in the examination box or the mix box are dispensed when a dispensing instruction to dispense the second denomination bills is given.
