Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If smartphone with NFC capabilities is used for access control and ticket validation, then multiple access functions are consolidated into a single device, but power consumption increases and battery life is limited
Solution Approach 1:
The patent extracts the essential access control and ticket validation functions from the smartphone, creating a dedicated standalone device. This removes the need for power-hungry components like large screens, cameras, and mobile communication modules while retaining NFC and other wireless communication capabilities for access functions.
Solution Approach 2:
The patent employs a minimalist hardware architecture with lower power consumption components, accepting that the device will have a limited operational lifespan on a single charge. This approach prioritizes power efficiency and cost-effectiveness over extended battery life, using simple visualization elements like LEDs instead of power-intensive displays.
2Adaptability or versatility
If smartphone with multiple components is used for access control, then various functions are integrated, but device cost and complexity increase
Solution Approach 1:
The patent extracts only the essential components needed for access control and ticket validation functions, removing unnecessary smartphone features. This results in a simplified device architecture with fewer moving parts and lower complexity while maintaining core functionality.
Solution Approach 2:
The patent designs a universal access device that can perform multiple functions (ticket validation, access control, parking) through a single NFC interface and communication module, eliminating the need for separate devices for each function and reducing overall system complexity.
3Ease of operation
If traditional physical interaction methods are used, then system infrastructure is simple, but user convenience decreases and wear and tear increases
Solution Approach 1:
The patent replaces mechanical interaction methods (swiping cards, inserting coins, physical key insertion) with contactless wireless communication technologies including NFC, Bluetooth, and RFID. This eliminates physical wear and tear on both user devices and system infrastructure while significantly improving user convenience through touchless operation.
4Adaptability or versatility
If multiple devices or cards are used for different access services, then service coverage is comprehensive, but user convenience and accessibility decrease
Solution Approach 1:
The patent merges multiple access control and ticket validation functions into a single standalone device. Users can store multiple digital tickets, access cards, and payment methods in one device, eliminating the need to carry multiple physical cards or devices and significantly improving convenience and accessibility.
Solution Approach 2:
The patent creates a universal access device capable of performing various functions (public transportation, parking, building access, garage door control) through a single interface, making the system adaptable to different services while simplifying user interaction to a single device operation.
