Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional card-based ATM access is used, then users can perform transactions at ATMs, but the system suffers from deteriorated card readers, technical malfunctions, and card loss or damage issues

Engineering Contradiction:

ImproveATM access reliabilityVSAvoidcard reader deterioration and technical malfunctions

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical card insertion system with an optical/electronic QR code scanning system. Instead of physically inserting a card into a deteriorating card reader, users present a QR code through a mobile device camera, which is then scanned and decoded by the ATM's imaging system. This eliminates wear and tear on card readers and removes the physical card as a failure point.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a digital copy (QR code) that represents the user's banking credentials. Instead of relying on a physical card that can be lost, stolen, or damaged, the system uses a regenerable digital representation stored on the user's mobile device. This digital copy can be repeatedly scanned without degradation.

Inventive Principle:

Principle #26Copying

2Productivity

If static Check Identity Records (CIRs) are used for fraud detection, then the system can process checks, but fraud detection confidence deteriorates over time

Engineering Contradiction:

Improvecheck processing capabilityVSAvoidfraud detection confidence

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent transforms the static CIR system into a dynamic one by implementing automatic updates based on newly processed checks. The system continuously refreshes the reference images in the CIR database, ensuring that the fraud detection algorithm compares new checks against the most current and relevant reference data, thereby maintaining high detection confidence over time.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback loops where processed checks are used to update and refine the CIR database. This feedback mechanism ensures that the fraud detection system learns from new data and adapts to changing patterns, maintaining accuracy and confidence levels despite the passage of time.

Inventive Principle:

Principle #23Feedback

3Reliability

If QR code scanning is implemented for ATM access, then card reader deterioration is eliminated, but the system requires additional components (camera, QR code generator)

Engineering Contradiction:

ImproveATM access reliabilityVSAvoidsystem components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent leverages the universal presence of camera technology in modern mobile devices. By using a camera for QR code scanning, the system repurposes an existing, widely available component rather than requiring specialized hardware. This approach minimizes additional complexity while achieving the goal of reliable, contactless access.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If conventional check processing is used, then US bank checks can be processed, but the system struggles with non-US bank checks and varying image qualities

Engineering Contradiction:

Improvecheck type compatibilityVSAvoidfraud detection accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent employs image processing techniques that adjust parameters such as contrast, brightness, and resolution to normalize varying image qualities. By dynamically adjusting these parameters, the system maintains consistent fraud detection accuracy across different imaging conditions and check types, including non-US bank checks with varying formats and languages.

Inventive Principle:

Principle #35Parameter changes

AI summary

A method comprising using at least one hardware processor to: receiving a QR code image associated with an ATM from an ATM machine; detecting through a mobile banking application the QR code features within the QR code, wherein the features are associated with an encoded information; decoding the detected QR code to extract the encoded information corresponding to the ATM; verifying the ATM machine to be used by the user; and granting access to the ATM and user account.
