ATM Cash Drawer Ink Layout for Explosion-Resistant Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ATM and Bancomat drawers lack sufficient space for marking devices due to the integration of burglary detection means, automatic banknote transport devices, and other electronics, and are vulnerable to explosion-induced failure of ink transfer systems.
Innovation Solution
A drawer design that integrates a marking device within the drawer itself, with a tank and distribution system positioned below the base support, ensuring the marking fluid is applied even in explosions, and does not exceed the available space by incorporating the necessary components efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the marking device is placed inside the drawer, then the marking function is ensured, but the available space for banknotes is reduced
Solution Approach 1:
The marking device is positioned in the vertical dimension below the base support rather than occupying horizontal space within the drawer body. This dimensional relocation allows the marking function to be integrated without reducing the available volume for banknotes, as the ink tank and distribution system are arranged in the unused vertical space beneath the drawer's base structure.
2Ease of operation
If the channelling system is used for ink distribution, then the marking process is simplified, but the system may break down during explosions
Solution Approach 1:
A flexible membrane is introduced as an intermediary element between the ink tank and the distribution system. This membrane acts as a pressure equalization and safety mechanism that allows the marking system to function during normal operation while protecting against explosion-induced failures. The membrane can deform to accommodate pressure changes without causing system breakdown, thereby maintaining reliability during explosive events.
3Volume of moving object
If the marking device is integrated into the drawer, then space is saved, but the drawer cannot accommodate large denomination banknotes
Solution Approach 1:
The drawer is segmented into functional zones: the marking device is isolated in the vertical space below the base support, while the main drawer body remains dedicated to banknote storage. This segmentation allows large denomination banknotes to be accommodated in the primary storage area without interference from the marking device components, maintaining both space efficiency and adaptability for various banknote sizes.
