Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If smartphones with NFC capabilities are used for access control and ticket validation, then multiple functions are consolidated into a single device, but the device requires complex, power-hungry components (large LCD screens, cameras, mobile communication modules) that limit battery life and overall durability
Solution Approach 1:
The patent extracts and removes power-hungry components (large LCD screens, cameras, mobile communication modules) from the device, keeping only the essential wireless communication modules (NFC, Bluetooth, RF, UWB) needed for access control and ticket validation functions
Solution Approach 2:
The patent employs a simple, robust housing design without fragile components like large screens or cameras, creating a durable device that can withstand frequent use in harsh environments
2Adaptability or versatility
If smartphones with NFC capabilities are used for access control and ticket validation, then various access control and ticket validation functions are integrated into one device, but the solution becomes expensive and requires a constant internet connection to function correctly
Solution Approach 1:
The device includes a local backend system that can process access control and ticket validation requests independently without requiring constant internet connection, enabling the device to function autonomously in offline scenarios
Solution Approach 2:
The system is segmented into the portable device with wireless communication modules and a separate backend system, allowing the backend to be deployed locally or cloud-based, providing flexibility in connectivity requirements
3Ease of manufacture
If traditional physical interaction methods (swiping cards, inserting coins, manually opening gates) are used, then system infrastructure is simple, but the methods are time-consuming and prone to wear and tear on user's access device and system infrastructure
Solution Approach 1:
The patent replaces mechanical interaction methods (swiping cards, inserting coins, manual gate operation) with wireless communication technologies (NFC, Bluetooth, RF, UWB), eliminating physical contact and mechanical wear while maintaining simple infrastructure
Solution Approach 2:
The device integrates multiple wireless communication protocols (NFC, Bluetooth, RF, UWB) to provide universal compatibility with various access control systems and ticket validation terminals, enabling seamless wireless operation
