Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing self-service terminals (SSTs) face space and legal constraints due to separate media interface aperture covers and PIN pads, limiting display screen size and vulnerability to identity theft through skimming and residue detection.

Innovation Solution

Integration of a combined media interface aperture cover and user interface component, including a PIN pad or encrypted touch screen, which can retract to dispense or receive media and prevent skimming and residue-based identity theft.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If separate media interface aperture cover and PIN pad are used, then device functionality is maintained, but device complexity increases and space is consumed

Engineering Contradiction:

Improvestructure complexityVSAvoidfunctional integration

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent combines the media interface aperture cover and PIN pad into a single integrated assembly. The PIN pad is positioned within the aperture cover structure, allowing both components to function as one unit. This merging reduces the number of separate parts, simplifies the overall device structure, and decreases the space required while maintaining both media interface and PIN entry functionalities.

Inventive Principle:

Principle #5Merging (Combining)

2Area of moving object

If separate media interface aperture cover and PIN pad are used, then functional requirements are met, but display screen size is limited

Engineering Contradiction:

Improvedisplay screen sizeVSAvoidcomponent arrangement

Core Design Contradiction:

Area of moving objectVSDevice complexity

Solution Approach 1:

By integrating the PIN pad into the aperture cover assembly, the patent creates a more compact structure that allows for a larger display screen area. The combined assembly reduces the overall footprint of the lower section of the device, freeing up space that can be allocated to the display screen, thereby increasing its size while maintaining functional requirements.

Principle #5Merging (Combining)

3Object-affected harmful factors

If touchscreen is used to avoid PIN skimming, then security against skimmers is improved, but residue analysis vulnerability remains

Engineering Contradiction:

ImprovePIN skimming vulnerabilityVSAvoidresidue marks

Core Design Contradiction:

Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the PIN entry function from the touchscreen interface and places it within the physical aperture cover structure. This separation means that PIN entry occurs on a dedicated pad within the closed aperture structure rather than on an exposed touchscreen, eliminating the residue marking problem while maintaining security against skimmers through the enclosed design.

Inventive Principle:

Principle #2Taking out (Extraction)

4Ease of operation

If small display screens are used, then legal compliance is achieved, but user accessibility and usability are reduced

Engineering Contradiction:

Improveuser accessibilityVSAvoiddisplay screen size

Core Design Contradiction:

Ease of operationVSArea of moving object

Solution Approach 1:

The integrated aperture cover and PIN pad design allows for optimized spatial arrangement that prioritizes display screen area. By consolidating the media interface and PIN entry functions into a compact unified structure, the patent maximizes the available space for the display screen, thereby improving user accessibility and usability while maintaining legal compliance through efficient space utilization.
