Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a mobile device incorporates contactless card technology and NFC chips for short-range communications, then data exchange capability is improved, but device complexity increases

Engineering Contradiction:
Improvedata exchange capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The NFC device is designed to perform multiple functions including contactless card operations, data exchange, and serving as a virtual card selector. The system allows a single NFC device to replace multiple separate functions (physical cards, multiple communication protocols), thereby improving adaptability while managing complexity through functional consolidation

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent creates virtual copies of physical cards in digital form within the mobile device. These virtual cards replicate the functionality of physical contactless cards but can be managed, selected, and modified digitally, enhancing data exchange capability while reducing the need for multiple physical card components

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If multiple payment applications are supported in a digital wallet, then versatility is improved, but ease of operation deteriorates due to selection complexity

Engineering Contradiction:
Improvepayment application versatilityVSAvoidapplication selection ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically determines which payment application to use based on the NFC card being presented. The mobile device autonomously selects the appropriate payment application by analyzing the card type and matching it with the corresponding digital wallet application, eliminating the need for manual user selection and simplifying the user interface

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback from the NFC card detection to dynamically select and switch between payment applications. When a card is presented, the system receives feedback about the card type and automatically adjusts the active payment application accordingly, creating a seamless user experience without requiring manual intervention

Inventive Principle:
Principle #23Feedback

3Ease of operation

If user interface modes are dynamically changed based on location and context, then user experience is improved, but processing requirements and energy consumption increase

Engineering Contradiction:
Improveuser experienceVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system periodically checks location and context parameters to determine when to switch user interface modes, rather than continuously monitoring and processing all possible changes. This periodic approach allows the device to balance improved user experience with reduced energy consumption by activating location-based mode changes only at appropriate intervals or triggers

Inventive Principle:
Principle #19Periodic action
