Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated teller machines (ATMs) face challenges in detecting manipulation attempts, such as skimming devices, which are difficult to distinguish from original controls and often require complex monitoring systems.
Innovation Solution
An ATM with a camera mounted inside the control panel housing, equipped with a wide-angle lens and connected to a data processing unit for image processing, edge detection, and classification, allowing for reliable detection of manipulation attempts and operational errors, including the use of additional cameras to monitor users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex monitoring systems with multiple sensors are used to detect manipulation attempts, then detection reliability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the manipulation detection function from complex multi-sensor monitoring systems and implements it using a simple camera system with image processing algorithms. The camera captures images of the control panel, and software analysis detects overlays or manipulations by comparing image features against reference patterns, eliminating the need for multiple physical sensors while maintaining high detection reliability
Solution Approach 2:
The patent replaces mechanical and electronic sensor-based monitoring systems with an optical camera system combined with digital image processing. Instead of using multiple physical sensors to detect manipulation, the system uses optical imaging and algorithmic analysis to identify manipulative actions, thereby reducing hardware complexity while improving detection capabilities
2Adaptability or versatility
If cameras are mounted outside the control panel to monitor the user area, then user monitoring capability is improved, but detection accuracy of manipulation attempts deteriorates
Solution Approach 1:
The patent merges the user monitoring function with the manipulation detection function into a single integrated camera system. The camera is positioned to simultaneously capture both the user area and the control panel, allowing the system to perform both user surveillance and manipulation detection through a single device rather than requiring separate monitoring systems
Solution Approach 2:
The camera system is designed with multi-functionality, serving both as a user monitoring device and a manipulation detection device. By positioning the camera to capture both the user area and control panel simultaneously, the system achieves universal monitoring capabilities without compromising the precision of manipulation detection
3Manufacturing precision
If narrow-angle cameras are used to capture detailed images of control elements, then image detail is improved, but coverage area deteriorates
Solution Approach 1:
The patent transitions from two-dimensional image capture to three-dimensional spatial coverage by positioning the camera at an angle that captures both close-up control elements and the broader user area. This angular positioning allows the system to simultaneously achieve detailed imaging of specific elements while maintaining wide coverage of the entire control panel and user interaction space

AI summary
An automated teller machine (ATM) is proposed having a control panel (CP) that has elements (1, 2, 3, 4, 5) arranged therein that are provided for users of the automated teller machine (ATM) and that has a camera (CAM) to detect manipulation attempts on the automated teller machine (ATM). The camera (CAM) is mounted in a housing section of the automated teller machine (ATM) surrounding the control panel (CP) and aligned in such a way that the camera (CAM) captures images of at least two of the elements (1, 2) arranged in the control panel (CP). In particular, the camera (CAM) captures image of the money dispensing compartment (1) and the keypad (2) in order to unequivocally detect any overlays installed there and similar manipulation or skimming attempts.
