Accounting Apparatus with Electromagnetic Lock for Secure Change Replenishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-checkout accounting systems lack a secure method for customers to replenish change machines, requiring store workers to manually handle and transport cash, which is time-consuming and risky for the store owner.
Innovation Solution
An accounting apparatus with a built-in stocking unit for money, featuring a locking mechanism that allows authorized personnel to unlock and replenish the change machine while maintaining security, using a money bar drawer and electromagnetic locks to control access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a self-checkout accounting apparatus is used by customers, then customer service efficiency is improved, but security risk increases due to lack of stocking units for security
Solution Approach 1:
The accounting apparatus enables customers to perform accounting operations independently through the self-checkout interface, eliminating the need for store workers to manually handle cash transactions. The system automatically manages money flow between the change machine and stocking unit, allowing customers to serve themselves while maintaining security through automated controls.
Solution Approach 2:
The control unit acts as an intermediary that manages the money transfer process between the change machine and stocking unit. It automatically detects money shortages, initiates replenishment operations, and controls the door locking mechanism, thereby mediating between customer operations and security requirements without human intervention.
2Reliability
If store workers manually replenish change machines, then security is maintained, but time and effort are consumed
Solution Approach 1:
The system performs self-replenishment operations where the control unit automatically detects when the change machine needs money, opens the door at appropriate times, and transfers money from the stocking unit to the change machine without requiring store worker intervention. This eliminates the time and effort previously spent on manual replenishment while maintaining security through automated control.
Solution Approach 2:
The control unit continuously monitors the money status in the change machine and receives feedback about money shortages. Based on this feedback, it automatically initiates replenishment operations by controlling the door locking mechanism and money transfer, creating a closed-loop system that responds to actual needs without human intervention.
3Ease of operation
If customers can access the stocking unit, then replenishment is simplified, but security risk increases
Solution Approach 1:
The control unit serves as an intermediary that manages all access to the stocking unit. It receives replenishment requests from the customer interface, validates them, and then controls the door locking mechanism to allow or deny access. This mediates between customer convenience and security requirements, allowing simplified operations only when properly authorized.
Solution Approach 2:
The door locking mechanism dynamically changes its state based on operational needs. The control unit locks the door during normal operation to prevent unauthorized access, but temporarily unlocks it during authorized replenishment operations. This dynamic control allows the system to be secure when needed and accessible when required, resolving the contradiction between security and ease of operation.

AI summary
According to one embodiment, an accounting apparatus includes: a case body that accommodates a change machine for dispensing a change and a stocking unit for stocking money to replenish the change machine; a door that is provided at the case body so as to be able to be opened and closed and closes an accommodation unit for accommodating the stocking unit; a first electromagnetic lock that is shifted between a locked state where the door is not able to be opened and an unlocked state where the door is able to be opened; and an opening and closing control section that maintains the first electromagnetic lock in the locked state in a normal mode in which accounting processing of driving the change machine such that the change machine dispenses a change with respect to a price of a sales target is executed, and enables the first electromagnetic lock to be shifted to the unlocked state in a specific mode based on an input of unlocking permission information for the electromagnetic lock.
