Modular Cash Register Assembly for Obstructed Box Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cash storage box of existing cash registers is difficult to remove from the cash collecting device due to obstructions by building structures or other facilities.
Innovation Solution
A cash register design that allows the banknote storage module to be assembled with the banknote input module from above or below, utilizing a banknote transport mechanism and a banknote storage pressure plate, with engagement recesses and protrusions for secure coupling, and a banknote transport path with inclined, horizontal, and arcuate sections, enabling flexible installation despite obstructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the cash storage box is combined with the cash collecting device in fixed positions, then the structural stability is improved, but the ease of installation and removal deteriorates due to obstructions by building structures or other facilities
Solution Approach 1:
The cash register is divided into separate modules: a banknote input module and a banknote storage module. These modules can be independently assembled and disassembled, allowing flexible installation in different locations without being constrained by building structures. The segmentation enables each module to be installed separately while maintaining overall system functionality.
Solution Approach 2:
The combination frame incorporates dynamic coupling mechanisms including engagement recesses, engagement protrusions, and latch structures that allow the modules to be easily connected and disconnected. This dynamic design enables quick assembly and disassembly operations while maintaining stable connection when assembled, resolving the contradiction between structural stability and ease of installation.
2Ease of operation
If the banknote storage module is detachably assembled to the banknote input module, then the ease of installation and removal is improved, but the structural stability deteriorates
Solution Approach 1:
The combination frame incorporates dynamic coupling mechanisms including engagement recesses, engagement protrusions, and latch structures that allow the modules to be easily connected and disconnected. This dynamic design enables quick assembly and disassembly operations while maintaining stable connection when assembled, resolving the contradiction between structural stability and ease of installation.
Solution Approach 2:
The banknote input module and banknote storage module are merged through the combination frame structure that integrates both modules into a unified assembly. The merging maintains structural stability when connected while preserving the ability to detach when needed, achieving both ease of installation and structural integrity.
3Reliability
If the cash register components are designed with engagement recesses and protrusions for secure coupling, then the reliability of connection is improved, but the device complexity increases
Solution Approach 1:
The coupling mechanism is segmented into standardized components: engagement recesses in one module correspond to engagement protrusions in the other module. This segmentation creates modular coupling elements that can be repeatedly used across different assembly configurations, maintaining reliability while managing complexity through standardization.
Solution Approach 2:
The engagement recesses and protrusions are designed as universal coupling features that can accommodate different module configurations. These multi-functional elements serve both alignment and securing purposes, reducing the need for additional specialized components and thereby managing device complexity while ensuring reliable connection.

AI summary
A cash register includes a banknote input module including a first housing and a banknote transport mechanism, and a banknote storage module including a second housing and a banknote storage pressure plate. The first housing has a banknote inlet, a banknote outlet and a first combination frame. The banknote transport mechanism is disposed in the first housing and located at the banknote inlet and between the banknote inlet and the banknote outlet. The banknote storage pressure plate is movably disposed in the second housing and abuts against the second combination frame. The first combination frame is coupled to the second combination frame of the second housing from above or below to combine the money input module with the money storage module. A banknote enters the first housing from the banknote inlet and is transported by the banknote transport mechanism and enters the second housing through the banknote outlet.
